The Cenozoic Era follows the end of the _______ period.
1.Triassic
2.Jurassic
3.Permian
4.Cretaceous
Answer:
Option (D)
Explanation:
The Cenozoic era starts after the end of the Cretaceous. It is marked by the global mass extinction event known as the Cretaceous-Tertiary (K-T) boundary. The Cenozoic era started from about 65 million years back to the recent.
The new species started to evolve from the start of this era and there were abundant land animals during this era, and so this era is often regarded as the age of mammals. This is the most recent era in the geological time scale and is marked by the diverse group of organisms that has appeared after a long evolutionary process.
The Cenozoic era is again divided into three parts-
1) Tertiary- It is divided into (a) Palaeogene, (b) Eocene, and (c) Oligocene
2) Neogene- It is divided into (a) Miocene and (b) Pliocene
3) Quarternary- It is divided into (a) Pleistocene and (b) Holocene
Thus, the correct answer is option (D).
What is the objective lens used to locate the specimen and first focus?
The objective lens of a microscope is used to locate the specimen and achieve initial focus. With magnification values typically from 5x to 100x, these lenses are parfocal, allowing for easy magnification changes while keeping the sample in focus.
The objective lens on a microscope is the lower lens used to locate the specimen and first focus on it. In a typical microscope setup, there are typically multiple objective lenses with magnification values ranging from 5x to 100x, which are mounted on a rotating turret that allows for changes in magnification. These objectives are generally parfocal, meaning they are designed so that the sample remains in focus when switching between different magnification objectives. The combination of the objective lens and the eyepiece or ocular lens enables the microscope to magnify small objects, where the objective lens plays a crucial role in establishing magnification and initial focus.
To properly view a sample, optimal illumination is necessary. The light source should be centered on the specimen, with parallel light rays focused by the condenser lens system. The condenser can be moved up and down to adjust focus, and the condenser diaphragm regulates the amount of light suitable to the size of the objective lens. To focus on the sample when using higher magnifications, an increased amount of light is needed.
Overall, the objective lens is instrumental in the first step of magnification and focusing, and when used in conjunction with the ocular lenses inside the eyepiece, it allows for detailed examination of microscopic samples.
How will the level of carbon in the atmosphere change if humans do nothing to reduce their impact on the carbon cycle?
Answer: If human beings will not do anything then the amount of carbon dioxide will increase in the environment. The amount of carbon dioxide will keep on increasing in the atmosphere because there are various sources by which it can be released into the environment. The burning of fossil fuel, emission from vehicles, gases released from industries contributes to the increase in amount of carbon dioxide in environment.

In symphysis joints the articular surfaces of the bones are covered with hyaline cartilage.
What is hyaline cartilage?
Hyaline cartilage covers the end of the bone in symphyses, but the link between bones is made by fibrocartilage. Symphyses are present at the vertebral joints. There is virtually little movement in any type of cartilaginous joint.
The symphysis pubis connects the bodies of the pelvic pubic bones. The cartilage covering the neighboring sides of these structures runs collagen fibers from one pubis to the other. The pubic symphysis is a one-of-a-kind joint made up of a fibrocartilaginous disc wedged between the articular surfaces of the pubic bones.
Therefore, Hyaline cartilage covers the articular surfaces of the bones in symphysis joints.

Which is not a requirement for natural selection to occur?
The Hardy – Weinberg principle has seven conditions that should occur in the evolution of the population. One is when mutation does not happen. Two, is when natural selection is not occurring. Three, if the population is infinitely large. Four, if all the members of the population produce offspring. Five, sexual intercourse is random. Six, the population will produce the same number of offspring. And lastly, the population does not migrate from one place into the other. The thing that would disrupt the genetic equilibrium is the mutation.

Explain why other factors besides heredity influence a person’s health.
Answer:
The other factors like eating habits, lifestyle and environmental conditions affects the person's health.
This is because the body is completely affected by the foods that we eat and the lifestyle in which we live in.
No matter how healthy a person is but once he or she starts having unhealthy fooding habits then the person will suffers from obesity and other respiratory disorders.
The health of the person depends on the food that he eats and the environment he lives in so a person's health is depends on the other factors more than hereditary.
Which of the following is a pseudocoelomate?
1.Fish
2.Shrimp
3.Roundworm
4.All Of The Above
Answer: 3.Roundworm
Explanation:
Pseudocoelomate animals which have a fluid filled body cavity. The tissues in these organisms are derived from the mesoderm. These organisms lack a circulatory system, lack a endothelial lining of a coelom. The hydrostatic pressure build inside the fluid body cavity is responsible for giving a body supportive framework that gives a skeletonic structure to the animal. Example of these organisms includes the nematodes or roundworms.

Which of the following is an example of active transport?
A. osmosis of water across the cell membrane
B. transport of glucose into a cell
c. the sodium-potassium pump found in nerve cells
d. none of the above
Any process that requires energy to diffuse is considered active transport. Since osmosis occurs naturally, this can be disregarded. The correct option is C.
Thus, the molecule is too big to normally enter a cell, glucose transport can either be active or passive.
A vital membrane protein present in animal cells, including nerve cells, is the sodium-potassium pump. In opposition to their concentration gradients, it actively transfers potassium ions (K+) into the cell and sodium ions (Na+) out of the cell.
This pump preserves the gradients in these ions' concentrations, which are essential for a number of cellular functions include nerve impulse transmission and maintaining cell volume.
Thus, Any process that requires energy to diffuse is considered active transport. Since osmosis occurs naturally, this can be disregarded. The correct option is C.

A lipid is any substance of biochemical origin that is insoluble in non polar solvent.
What are lipids?The fundamental units of the composition and operation of living cells are lipid molecules, which are hydrocarbon-containing molecules. Lipids contain things like fats, oils, waxes, some vitamins (including A, D, E, and K), hormones, and the majority of the cell membrane that isn't protein.
Since lipids are non-polar, they cannot dissolve in water but can do so in non-polar solvents like chloroform.
When metabolized, the hydrocarbons in lipids oxidize to release significant amounts of energy, making lipids an efficient type of energy storage.
Therefore, A lipid is any substance of biochemical origin that is insoluble in non polar solvent.

"during which phase of mitosis does the nuclear membrane dissolve completely and the chromatid pairs arrange themselves in a single file?"
The answer is metaphase. It is marked by the arrangement of chromosomes at the center of the cell, half way between each of the mitoic spindle poles. Movement is intermediated by the kinetochore microtubles, which push and pull on the chromosomes to align them into what is called the metaphase plate. The chromosomes on the metaphase plate are held there firmly by pushing and pulling forces from the microtubules. Cells can stop in metaphase for days until the chromosomes are properly aligned and the cell go in anaphase.
The prophase of mitosis is the phase in which the nuclear membrane dissolves completely and the chromatid pairs arrange themselves in a single line. This prepares them for segregation during metaphase.
Explanation:The phase of mitosis you're referring to, in which the nuclear membrane dissolves completely and the chromatid pairs arrange themselves in a single file, is the prophase. During prophase, the nuclear membrane breaks apart and the chromatids congregate at the center of the cell. They become organized in a structure known as the mitotic spindle, which will help separate the chromatids in a subsequent phase, metaphase. This is a crucial step in the cell division process which ensures the correct distribution of genetic material to the two daughter cells.

Explain how individual and public health are affected by environmental and genetic factors.
Environmental and genetic factors jointly shape individual and public health. Environmental influences include exposure to toxins and lifestyle choices, while genetic factors can predispose individuals to certain health conditions.
Both environmental and genetic factors play a significant role in individual and public health. The environment can influence phenotypes such as body weight, which is also subject to genetic tendencies. Lifestyle choices like diet and exercise can mitigate or exacerbate these genetic tendencies. For example, two people with the same genetic predisposition to obesity might have different outcomes based on their environments and behaviors.
Environmental health is a public health branch that studies the interaction between human health and the environment. Factors like air quality, water contamination, and exposure to toxic substances can influence health outcomes. At the same time, human activities impact environmental conditions, creating a cyclical relationship.
Genetic factors also have a deep impact on health. Specific populations may be more susceptible to certain diseases due to inherited conditions like sickle cell disease. Genetic predispositions necessitate that individuals consider both lifestyle modifications and increased disease screenings to potentially reduce health risks.
However, genetics alone do not determine health outcomes. Environmental stress and lifestyle choices interact with genetic makeup to influence an individual's response to environmental stress and risk for diseases. Understanding this interplay is crucial for addressing noncommunicable diseases like obesity that are prevalent in industrialized societies.
