How does a cell control the process of cell division?
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.

Answer:
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
The cell membrane is semi-permeable only allowing certain materials in and out of the cell?
True
False
In other words, plasma membranes are selectively permeable—they allow some substances through but not others. In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.

How are bacteria cells DIFFERENT from plants/animal cells?
How are bacteria cells SIMILAR from plants/animal cells?
Answer:
Difference:Bacteria cells are very different from animal, plant or fungal cells. They don't have organelles such as nuclei, mitochondria or chloroplasts. Although they do have ribosomes and a cell wall, these are both different in structure to the ribosomes and cell walls in the cells above.
Similar:Plant cells and bacteria alike have cell walls, strong flexible layers surrounding their cell membranes that help to counteract osmotic pressure so the cell does not burst as water diffuses into it.
Explanation:

The ability of certain specifically shaped molecules to attach to a cell is
primarily determined by the cytoplasm of the cell
Organisms have structures which are known as intracellular receptors
which are found in the cytoplasm of cells .
These receptors help in the binding of molecules such as protein which are
useful by the cells for synthesis and other metabolic processes required for optimal functioning.

Compare how the surface area for gas exchange is increased in gills and lungs
The gills and lungs of vertebrates are designed to have as much surface area as possible for gas exchange. A dense network of blood arteries is present on the alveoli's partitions.
What is a gas exchange?As a result, lungs maximize the area for the gaseous transition by having a wide range of alveoli that are well supplied with blood.
A portion of the lungs in humans are constructed of bronchioles, alveoli, which resemble balloons, and a network of blood capillaries that serve as the groundwork for gas exchange.
Therefore, this takes place in the lungs between the alveoli and a group of microscopic blood arteries called capillaries that are positioned inside the alveoli's borders.

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

Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere?
1. Explore: Use the Gizmo to create a path for carbon that begins and ends in the atmosphere. Fill in the
steps in the path below. Then, label each location with the system it represents. Finally, summarize very
briefly how the carbon atom got to that location.
Answer:
Yes.
Explanation:
Yes, everything made or modified by humans with the help of knowledge and education. Without knowledge it is impossible to made new things or modify it. Carbon move from atmosphere to the biosphere by the process of photosynthesis done by plants in order to produce their own food so for that reason the plants take carbondioxide from the atmosphere and change into food whereas in the breathing of organisms this carbon moves again to the atmosphere. Carbon also moves from atmosphere to hydrosphere by dissolved in ocean water and lakes and the volcanic eruption and acid rain causes exchange of carbon between atmosphere and geosphere.
