All organisms, including plants, undergo what essential process?
A. Photosynthesis
B. Cellular Respiration.
C. Sexual reproduction.
Answer:All the living organisms undergo cellular respiration.
Option B
Explanation:Cellular respiration is the process of production of energy from food. This process includes different chemical reactions which squeeze out energy from the food and store that in form of Adenosine Tri Phosphate for the cells to use in future. Thus without cellular respiration, a cell can't survive.
Now the photosynthesis is only restricted within a group of autotrophs which contains chlorophyll and can use Sun's energy to produce glucose from carbon dioxide and water.
Sexual reproduction is also not a feature of many lower organisms like bacteria which divide by means of binary fusion.

Which of the following statements are true about hemophilia?
It is an example of an autosomal dominant disorder.
It is an example of an autosomal recessive disorder.
It is an example of a sex-linked disorder.
It involves a protein inside the red blood cells.
It is a disease in which a person has trouble stopping bleeding.
Its a sex linked disorder and it makes stopping the bleeding slower in affected individuals.
Explanation:Hemophilia is a sex linked recessive disorder which occurs due to a gene present in the X chromosome. The presence of this gene in males surely make the individual hemophilic because the Y chromosome doesn't contain any dominant factor of this gene. In females, the recessive individuals become carriers without expression of this gene. Only the dominant individuals in females expresses Hemophilia.
Its a disease where the Christmas factor (Factor IX) or the antihemophilic factor(Factor VIII) is absent in the affected individual. This makes the cascade theory incomplete and there's a defect in blood clotting in both the intrinsic and extrinsic pathways. Thus the persons if starts bleeding, loses a lot of blood before coming to a stability.
Answer:C.) It is an example of a sex-linked disorder. E.) It is a disease in which a person has trouble stopping bleeding.

Explanation:
Teoría cinética molecular. Las leyes de los gases desarrolladas por Boyle, Charles y Gay-Lussac, que establecieron las principales relaciones entre la presión, el volumen y la temperatura de un gas, están basadas en observaciones empíricas y describen el comportamiento de los gases en términos macroscópicos.
The statement which best describes the Kinetic Theory Model is that When particles in matter gain or lose energy, they change state. Thus, the correct option for this question is C.
What is the kinetic theory model?The kinetic theory model may be defined as a type of theory that significantly states that all matter is composed of particles in motion and that the rate of motion varies directly with the temperature. As the temperature rises, the movement of particles gradually increases.
According to this theory model, the molecular composition of the gas is in terms of a large number of submicroscopic particles which include atoms and molecules. Further, the theory explains that gas pressure arises due to particles colliding with each other and the walls of the container.
Therefore, when particles in matter gain or lose energy, they would definitely change state with respect to the energy that is administered to them. Thus, the correct option for this question is C.

A heterozygous male and a homozygous female plants are cross-pollinated. What is the genotypic ratio of the offspring
Answer:
When a heterozygous male and homozygous female plants are cross-pollinated the genotypic ratio of the offspring will be tt, Tt
Explanation:
In a pea plant, when the heterozygous male plant (Tt) is cross-pollinated with homozygous female plant (tt) ;
T × t = Tt
t × t = tt
t × T = tT
t × t = tt
Therefore, the genotypic ratio of the offspring is short and tall (tt, Tt) because the dominance of tall trait is less that the short trait, indeed the chances of tall offspring is low.

1. Wind and moving water provide____ energy. A.chemical
B.mechanical
C.thermal
D.none of the above
plz help;-;
Answer: most likely D
Explanation:
A was close, B not it and C is only for heat use
Wind and moving water provide mechanical energy. They are renewable energy sources that harness the kinetic energy of natural movements to generate electricity. The correct answer is option (B).
Wind and moving water provide a form of energy known as mechanical energy. This type of energy is harnessed through the movement of turbines which convert the kinetic energy of wind or flowing water into electrical energy. Both forms of energy, wind power and hydroelectric power (hydroenergy), are considered renewable energy sources.
Winds and moving water are driven by the energy from the sun, which heats the Earth unevenly, causing wind, and evaporates water to high elevations, where it can later fall and flow due to gravity, powering turbines as it moves. This mechanism is similar across different forms of energy generation, such as fossil fuels, biofuels, nuclear energy, and solar thermal systems, where a spinning turbine creates an electric current.
Thus, the correct answer to the student's question is option B) mechanical energy.

Identify the producers and consumers in this food web which organisms in the food web receive their energy directly from sunlight?
The cactus and brittle bush get their energy from sunlight because they are plants and use photosynthesis to make their own food.
Final answer:
Plants, algae, and some bacteria are the producers in the food web that receive their energy directly from sunlight.
Explanation:
Producers in a food web are organisms that conduct photosynthesis or synthesize sugars through other means, such as plants, algae, and some bacteria. These organisms obtain their energy directly from sunlight and convert it into usable chemical energy. Consumers, on the other hand, rely on producers, either directly or indirectly, for their energy. They include animals, fungi, and various microorganisms. For example, a deer receives its energy by eating plants, which in turn obtained their energy from sunlight. Therefore, the producers in the food web that receive their energy directly from sunlight are the plants, algae, and some bacteria.

An excessive, abnormally large scar is a:
O callus.
O corn.
O cicatrix.
O keloid.
A keloid is an excessive, abnormally large scar caused by an overproduction of collagen that exceeds the original wound and may continue to grow even after it has healed.
Explanation:The excessive, abnormally large scar referred to in the question is known as a keloid. Unlike a callus, corn, or cicatrix, which are all common types of scar formations, a keloid forms when the healing process in the skin extends beyond the original wound, resulting in a large raised scar. This is due to an overproduction of collagen, creating a smooth, hard growth. It is important to note that keloids may continue to grow long after the wound has healed.
