Answer:

B. Mosquitoes are limited by temperature, with reproduction levels high in the spring and summer and low in the fall and winter.

-Explanation:

Since mosquitoes reproduce when the temperatures are warm, their populations undergo a predictable increase in the warmer months. The first frost will kill many of the larvae and decrease the reproduction of these short-lived individuals.

What is the structure of DNA?

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.

Deoxyribonucleic acid (DNA) is made up of the four nucleotides A, C, G, and T. These nucleotides are linked together by a backbone made up of alternating phosphate and deoxyribose sugar residues. The complementary pairs of these nitrogen-containing bases are governed by their capacity to generate hydrogen bonds.

DNA is located inside the nucleus, a specific region of the cell, in eukaryotic species.

Therefore, chromosomes are the name for this DNA that has been packed.

The PH at which an enzyme will function best is;

In the optimal range

Explanation:

Every enzyme has an optimal pH value which is specific for the enzyme, and where their maximum activity of the enzyme is observed, which is known as its optimal pH

When the enzyme is placed in a different pH, the enzyme activity is observed to be diminishing until the effect of the enzyme stops

This is so because, as the pH of the environment changes, the shape of the active site on the substrate to which the enzyme binds to have an effect changes and the enzyme is no longer able to effectively interact with the substrate

The enzymes in the stomach work best in the acidic environment of the stomach and have an optimal pH of 2, while the enzymes of the small intestine have an optimal pH of 7.5

Since sun can filter to the bottom of a pond because it is shallower than a lake, what would you find at the bottom of a pond that you won't find at the bottom of a lake? A. Rocks B. Fish C. Plants D.Mud

Answers

Answer:

The correct answer is - C. Plants.

Explanation:

As we know and also given that the pond is usually smaller and shallower than a lake. Due to this reason, ponds have plants growing on the bottom of them from one side to the other as they get enough light as there is only the photic zone in ponds.

In lakes, there are various zones present and the lakes are deep and big to the ponds and the bottom of the lakes did not get sunlight. Plants require sunlight to grow and lakes are usually too deep to get the sunlight for plants to grow on the bottom.

How does a cell control the process of cell division?

Answers

In cell division, the cell that is dividing is called the "parent" cell. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.

Cells control their division by communicating with each other using chemical signals from special proteins which is known as cyclins.

What is Cell division?

Cell division is defined as the process by which a parent cell divides into two daughter cells usually as part of a larger cell cycle in which the cell grows and changes its chromosomes before dividing.

A single cell divides to give rise to two cells where these two cells then divide to form four cells, and so on. This process is called "cell division" and "cell reproduction" because new cells are formed when old cells divide. This plays an important role in all living organisms which is essential for growth, repair and reproduction.

This process helps in:

Renewing of damaged cells. Production of new cells from older ones.

Thus, cells control their division by communicating with each other using chemical signals from special proteins which is known as cyclins.

Helppppp please What characteristic of water
means that clear water is not
necessarily clean water?
A. the density of the water
B. high specific heat capacity
C. the temperature of the water
D. ability to act as a universal solvent

Answers

Answer:

Explanation:

Ability of water to act as a universal solvent means that clear water is not necessarily clean water. Therefore, option (D) is correct.

What is clean water?

Clean, safe water is defined by the USGS as "water that won't hurt you if you come in touch with it." Although drinking water is often mentioned when discussing clean water, clean water is also crucial for all residential uses.

It is impossible to smell, taste, or even see the microscopic contaminants that pollute water, such as bacteria, viruses, and parasites. Therefore, just because your water is clear doesn't imply it's okay to drink.

Therefore, due to the fact that water is a universal solvent, meaning that it is capable of dissolving a wide range of substances with relative ease clear water is not considered clean.

Through these fossilized artifacts, scientists can make conclusions. Some hominid trends include a flatter face as hominids modernized. Refer to diagram M. According to Hominid trends, which of the three jaws would most likely b that of a modern hominid?

Answers

Answer:

The first and second hominids have a more recent common ancestor than the first and third hominids.

Explanation:

The similarity in DNA can definitely reveal us about common ancestry but it does not guarantee that the two species must be mating and reproducing. The best example to support this statement is that humans and chimpanzees share a common ancestor and both have so much similarity in their DNA. The DNA of humans and chimpanzees is around 99% similar but still humans and chimpanzees cannot mate to produce off springs. Several attempts have been made in past to obtain fertile off springs by mating humans and chimpanzees but so far their mating has not produced any fertile off spring.
