Answer:
It occurs only in cells in the reproductive structures of organisms.
Explanation:
Meiosis only occurs in the reproductive cells, producing gametes with half of the genetic information as the parent cell.
Meiosis can be best described as the event which occurs only in the cells which are the part of reproductive structures in an organism. Thus, the correct option is B.
What is Meiosis?
Meiosis is a type of cell division which occurs in sexually reproducing organisms. It is also known as reductional division as in this division, the chromosomal number is reduced to half. This division is responsible for introducing genetic variations in a population.
Meiosis is a type of cell division which occurs in the sexually reproducing organisms. This division is responsible for reducing the number of chromosomes in the gametes or sex cells such as eggs and sperms by half. In humans, normal body cells or somatic cells are diploid in nature. These cells contain two sets of chromosomes i.e., one from each parent.
Therefore, the correct option is B.

Explanation:
single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because...
Answer:
Because cells maintain homeostasis despite the amount.
Explanation:
When a change occurs in an animal’s environment, an adjustment must be made so that the internal environment of the body and cells remains stable. The receptor that senses the change in the environment is part of a feedback mechanism. The stimulus—temperature, glucose, or calcium levels—is detected by the receptor. The receptor sends information to a control center, often the brain, which relays appropriate signals to an effector organ that is able to cause an appropriate change, either up or down, depending on the information the sensor was sending.
Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.
Unicellular organisms like bacteria have various ways of maintaining homeostasis. There are various cellular structures and particles to maintain homeostasis. For example,
Bacteria also have sensors, a protein molecule, that sense and respond to toxic levels of heavy metals in the environment and also help regulate beneficial metal ions.Unicellular such as bacteria can control the lipid composition in their plasma membranes to regulate the permeability for substances to move in or out.Bacteria and paramecium are unicellular organisms that use contractile vacuoles to control the amount of water inside of them.Thus, Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.

Which of the following can limit the growth of a population of organisms?
Group of answer choices
A. Neither the number or predators nor diseases can limit the growth of a population of organisms.
B. The number of predators can limit the growth of a population of organisms, but diseases cannot.
C. Both the number of predators and diseases can limit the growth of a population of organisms.
D. Diseases can limit the growth of a population of organisms, but the number of predators cannot.
Answer:
c
Explanation:
population growth is entirely dependent on both of these
The one can limit the growth of a population of organisms is the number of predators, and diseases can limit the growth of a population of organisms. The correct option is c.
What is the population?The amount of people in a population is referred to as its population size. The average number of people per unit of area or volume is referred to as population density. This is a term that refers to the human population that lives in a specific geographical area.
The map depicts the concentration of the human population on the planet from all the continents depicted. A population pyramid is a diagram that depicts the total number of organisms that are successfully living and interacting with one another in a specific location at a given time.
As a result, the population pyramid predicts that the population is increasing.
Therefore, the correct option is C. Both the number of predators and diseases can limit the growth of a population of organisms.

Explanation:
An increase in the volume of forests and phytoplankton would lead to a reduction in free "blank" , which in turn could cause a decrease in carbon dioxide in the atmosphere.
Answer: Carbon dioxide
Explanation:
The forests and phytoplankton are carbon sinks, which absorbs the green house gas carbon dioxide from the atmosphere for photosynthesis. The carbon dioxide from the atmosphere and water are used as reactant in photosynthesis to yield carbohydrates and oxygen as products. Thus the carbon dioxide level in atmosphere decreases. This is necessary for controlling pollution in the environment and reducing the environmental temperature as carbon dioxide can make the environment warm.
Which finding would have disproved Virchow’s hypothesis?
1.) Animalcules are not organisms.
2.) Animals are made of non–cell-based matter.
3.) Plants are made of non–cell-based matter.
4.) Cells can generate from nonliving matter.
Answer:
Virchow was a German scientist whose most important work was in the filed of cellular biology and pathology.His scientific experiments and examinations aimed to disprove the idea of spontaneous generation. This idea is based on an assumption that life can spontaneously appear out of non-living matter. After years of scientific work he concluded that only living cells can produce other cells, or that only life can produce life.Therefore, if it was somehow proven that cells can be generated from non-living matter, that would disprove his findings.

It is not coal. I know that for sure, that is why it's not an option here.
Answer:
Hydrates
Explanation:
they're the most abundant source of natrual gas. "Hydrates are a much more abundant source of natural gas than conventional deposits. According to the U.S. Geological Survey, global stocks of gas hydrates range account for at least 10 times the supply of conventional natural gas deposits, with between 100,000 and 300,000,000 trillion cubic feet of gas yet to be discovered."

The process through which scientists review one another's work to validate results and conclusions, is the best definition of peer review. The correct option is D.
What is peer review?The system of peer review is employed to assess the merit of a manuscript prior to it being published.
Independent researchers in the relevant research area evaluate submitted manuscripts for originality, validity, and significance to assist editors in deciding whether to publish a manuscript in their journal.
Peer review is essentially an academic term for quality assurance. Each article that appeared in a peer-reviewed journal was thoroughly reviewed by a panel of experts on the topic of the article.
Peer review is meant to evaluate the validity, quality, and, in some cases, originality of articles submitted for publication. Its ultimate goal is to protect scientific integrity by filtering out invalid or low-quality articles.
Thus, the correct option is D.
