Answer:
Option (1).
Explanation:
Enzymes are the bio catalyst that increases the rate of biochemical reactions of the body. Enzymes are highly specific in nature and works at optimum temperature and pH conditions.
The enzymes work according to the lock and key mechanism. This mechanism explains that the active of enzyme should fit into the substrate in such a way as the key fits into its lock. Hence, this determines the complementary shapes of the substrate and enzyme.
Thus, the correct answer is option (1).
The Smith family is afflicted with a genetic disorder known as Pinocchio nose syndrome, which causes affected adults to grow noses in excess of five inches long. 100 members of the Smith family show up for a family reunion. Of the fifty-three women, thirty-seven have unusually large noses. Of the forty-seven men, thirty-six have an enormous nose. Based on these figures, Pinocchio nose syndrome is probably
A) dominant and sex-linked.
B) recessive and sex-linked.
C) dominant, but not sex-linked.
D) recessive, but not sex-linked.
Answer:
C- Dominant, but not sex-linked
Explanation:
The disorder is not sex-linked because almost equal numbers of people have Pinocchio nose syndrome. If the disorder was sex linked you would have way more men than women having the disorder.
You can tell that the genetic disorder is dominant because there is a 3:1 ratio for those who have the disorder.
36 out of 47 men ≈0.765
37 out of 53 women≈0.69
These numbers approximate a 3:1 ratio (even if it's not exact), meaning that the disorder is most likely dominant
the answer is actually D. not sex-linked but unable to tell if it is dominant or recessive

Fungi can act as decomposers in the environment. Why is this inportant
Answer:
Fungi help in clear waste and dead material and provide nutrients to the plants.
Explanation:
Decomposers are very essential for any food web in an ecosystem. If there were no decomposers in any ecosystem, the autotrophs would not get important nutrients, and waste and the dead matter would pile up.
Fungi are the primary decomposer of litter in most of the ecosystem. They decompose dead, organic matter or waste by releasing various enzymes to break down the material. They absorb the nutrients form in the decaying material.
Hyphae are the part that breaks down and absorbs nutrients,
Thus, the fungi help in clear waste and dead material and provide nutrients to the plants.

which body system produces movement by contracting and relaxing
Answer:
The Muscular System
Explanation:
Answer:
Muscular system
Explanation:
The muscular system is made up of different cells that is referred to as muscle fibers, which their function is based on contraction and relaxation. The movement in our body is possible as result of contraction because their is an attachment of the muscle to the body internal organs. This movement as result of contraction aid the body joint stabilit( this as a result of extension of tendons over the body joints), posture(responsible fort us to stand and sit).
The skeletal muscles in our body are in active service to make sure thebody is held in stationary positions.they provide the free movement that allows the body to run and walk, in addition they provide subtle eye movement and even facial expressions.

Explanation:
Elizabeth is getting ready to run a marathon. She's hoping that the ATP in her body is good for long-term energy storage for the race. Why is her thinking incorrect?
Answer:
Her Thinking is wrong because ATP is not a long term Energy Storage.
Explanation:
We need energy to perform every single task of everyday life. This energy is obtained from the food we eat. There are three main sources of energy in our food.
1. Carbohydrates
2. Lipids
3. Proteins
Carbohydrates are hydrolyzed into glucose upon breakdown and this glucose is used as energy by most of the cells. While Lipids are more complex molecules and usually used to store energy to be used later. Proteins help in muscle building and provide essential amino acid to the body.
There are two ways to store energy, Long term storage and short term storage. The ATP is obtained by breaking down the large molecules and considered as short term energy as it last for only few seconds. While the long term energy is obtained from lipids hydrolysis.
Answer:
ATP is an unstable molecule
Explanation:
Recall that ATP and ADP are too unstable to serve as long-term energy storage units. In contrast, glucose has a stable molecular structure, so it stores energy more efficiently than ATP.

How can you quantify total biomass in a region?
Total biomass in a region is quantified by measuring the blank mass of all the plants and blank in a population, habitat, or region.
Answer:
Quantifying biomass will depend on the quantity of the biomass and what is being measured. Biomass is the mass of living biological organisms in a given area, species or community at a specified time, which include plants, microorganism or animals.
Answer:
The correct answer would be - 1) Dry and 2) animals.
Explanation:
The biomass is the total or collective mass of the dry matter available in the particular ecosystem at any particular time. The representation of biomass is a pyramid known as the pyramid of biomass.
Biomass includes the animals and plants and other organisms present in that ecosystem.
Biomass is the total mass of all living material within a certain area. This includes all plants, animals and other organisms found there. The area is defined by a scientist so that it can be a specific habitat or region.
Thus, the correct answer is - 1) Dry and 2) animals.
Assume that tall (represented by T) is dominant over short stature (represented by y) in corn. If
a heterozygous tall plant is crossed with a short plant, show, using ratios the genotypes and
phenotypes you would expect the seeds from this cross to produce
a. Genotypes _____________________________________________
b. Phenotypes ____________________________________________
Answer:
a. 1 : 1
b. 1 : 1
Explanation:
In this case, a heterozygous tall plant (Ty) is crossed with a homozygous short plant (yy) - which we can deduce as the recessive alleles only exhibit themselves in the absence of the dominant alleles.
The resulting offspring would have the genotypes (refer to attached image):
Ty (Tall)
Ty (Tall)
yy (short)
yy (short)
The genotypic ratio would be - 1:1 (Ty & yy are the genotypes present)
and the phenotypic ratio would be - 1:1 (tall and short are the phenotypes present)

What's responsible for preventing the gas giants from collapsing into a star?
Gas giants do not have enough mass that holds much gravitation force to ensure collapsing into a star. The gravitation pull is not strong enough to cause the fusion of hydrogen atoms. These gas giants, such as Jupiter, therefore, do not become stars.
Answer:
They spin very quickly on their axes.
Explanation:
The gas giants spin very quickly, creating a strong centrifugal force. This strong centrifugal force prevents them from collapsing under gravity.

Our body temperature will stay around 98.6 degrees, even when it is hot or cold outside. This is an example of:
A. A behavioral adaptation
B. Structural Adaptation
C. Homeostasis
D. Equilibrium
Answer:
Option C, Homeostasis
Explanation:
Homeostasis is a mechanism through which body maintain its state of stability/equilibrium. Thermoregulation is one of the mechanism of homeostasis by which body maintain its internal temperature. The average human body temperature is 98°F (37°C). When the external temperature increases, the body sweats or vassolidate to maintain the stable temperature.
When the external temperature decreases, the body undergo vasoconstriction or thermogenesis to main its average temperature.

Which should be true about a research topic? A. It should have unlimited scope. B. It should be of interest to you. C. It should have been researched by at least two others. D. It should have a large number of keywords.
A research topic should be of interest to you (option B). It should engage your passion, have a manageable scope, be nuanced and debatable, and allow for various perspectives.
Explanation:When choosing a research topic, it should be of interest to you - option B is correct. A good research topic is one that engages your curiosity and passion, which can make the researching and writing process more enjoyable and fruitful. A topic with unlimited scope would be too broad to handle in a single paper and creating a research question with too many specific keywords could limit the exploration of the topic. Moreover, while it can be beneficial if the topic has been previously researched, it is not a requirement that it must be researched by at least two others; what matters is that you can find sufficient material and evidence to support your research. Lastly, the topic should be nuanced and debatable, allowing for various perspectives and insights rather than a simple yes-or-no question.
Teddy is explaining to his class that hydrothermal vents form isolated ecosystems. Which point should he explain? A. The organisms of the hydrothermal vent do not interact with the organisms of different ecosystem. B. The organisms of the hydrothermal vent are a part of other food webs. C. There is a continuous input and output of energy and materials in the hydrothermal vent. D. Sunlight plays a vital role in the hydrothermal vent ecosystem.
Answer:
A
Explanation:
In such an isolated ecosystem, there is usually an autotroph species that coverts the abiotic elements in the environment to biotic elements. In a hydrothermal vent, it is likely that there are some chemoautotrophic bacteria that covert the sulfur and other chemicals in the water into organic molecules. This energy is then transferred up the food web in the closed ecosystem. In such an ecosystem, even the waste product of one life form may be utilized by another species.

how are mitosis and meiosis similar?
Answer:
Explanation: both involve cell division although meiosis breaks it down farther. they have the same process names as well.
Answer:
Cell division is taken by two different means: meiosis and mitosis. Both types of cell divisions have similarities even though they have a different purpose. The mitotic cell division generates 2 daughter cells with the same number of chromosomes while meiosis produces 4 daughter cells with half number of the chromosome to their parent cells.
Except for this, meiotic and mitotic cell divisions are similar in the mechanism. Both cycles go through multiple stages. In these multiple stages both meiotic and mitotic cell division experience the same events as DNA replication and condensation, spindle formation, segregation of chromosomes and nuclear formation .
Thus, both cell cycles have several similarities.

which layer or Earth has partially melted material that moves the tectonic plates??
A - Crust
B - Inner Core
C - Mantle
D - Outer Core
Answer:
Mantle
Explanation:
The correct answer is C. Mantle
Explanation:
The Earth's mantle is one of the layers that compose Earth; this differs from other layers because it is partially melted and it represents most of the volume of Earth. Besides this, its composition and location below the outer core make this layer responsible for changes and phenomena in the surface such as volcanoes, new mountains, and Earthquakes, this is because the tectonic plates are over the mantle and the mantle is composed of soft and flexible materials that move and change. According to this, the mantle is the layer with partially melted material that moves the tectonic plates.
Which hypothesis is best supported by this graph?
A graph is supported by a line, so probably a line.
The hypothesis is best supported by this graph is the Cardinals’ food supply increased. Therefore option D is correct.
This can be inferred from the increasing trend in the number of cardinal chicks over time. As the food supply for cardinals increased, more chicks were able to survive and thrive, leading to an increase in the population of cardinal chicks.
The graph does not provide direct evidence or information about the population of cardinal predators, the feeding behavior of dominant cardinal chicks, or the spread of disease among cardinals.
Therefore, the most reasonable explanation based on the information provided is that the increased food supply contributed to the increase in the number of cardinal chicks observed in the graph.

Difference between bioprospection and biopiracy
Bioprospection is an attempt to search for new chemical contents in living things, both microorganisms, animals, and plants that have the potential as a drug or other economic benefits while Biopiracy is the theft of biological resources for the benefit of certain parties and detrimental to other parties
Further explanation
From the answers above it can be concluded that bioprospection and biopiracy are the opposite.
Bioprospection can be said to have two different sides. On one hand, the many bioprospecting activities provide opportunities to make human life better. While on the other hand, this activity poses a threat to biodiversity because it provides opportunities for biopiracy.
Biopiracy is often done by parties with advanced technological developments, but do not have enough biological resources for their progress. So developing countries that are rich in biological resources become their main goal. The government and the community may be familiar with the main goals of the developed countries but often cannot hamper the pace of biopiracy.
The solution is:
By making national laws and regulations and international laws. To make bioprospection truly prosperous without worrying about the occurrence of biopiracy, in addition to the drafting of the law, many things must be addressed and considered. Because bioprospection activities should also be subject to various international and national regulations to prevent the occurrence of biopiracy practices.

Both Bioprospecting and Biopiracy are contradictory to each other.
Bioprospecting involves research for potential usage of any animal or plant species for economic purposes such as usage in drugs, cosmetics, or any other industry. Biopiracy is the illegal or unlawful usage of purposeful plants or other species which prevents its general usage to certain parties providing commercial benefits to others.Explanation:
Bioprospecting :Many plants and animals have medical usage that could cure many diseases and other conditions, apart from the medical usage these species can also be beneficial for other sectors such as agriculture, cosmetics, and others. Bioprospecting is the legal and well-organized search for such species which can yield benefits to companies and governments.Bioprospecting has many benefits such as it promotes research and development, it helps in deep research of many species of plants and animals which in turn provides medical and economic benefits.Biopiracy:The ill use of intellectual property rights and exploitation of indigenous natural resources claiming unauthorized patents and GIs. Many countries and companies exploit vulnerable countries and their people by claiming authority over their products through finding loopholes in-laws is called biopiracy.
