Answer:
There would be two populations of fish:
Light-colored fishes near the surface
Dark-colored fishes near the bottom.
Explanation:
After many generations, there would be two populations of fish: Light-colored fishes near the surface and Dark-colored fishes near the bottom as light-colored fish survive better near the surface and dark-colored fish survive better near the bottom due to the lighting conditions and predators in the new habitat.

Calculate the mass of the book on the moon.
On moon surface gravity (g) is 1.6 N/kg
Answer:
The Moon has a smaller mass than the Earth and so the pull of gravity by the moon on an object is smaller than on the earth. The moon has a smaller gravitational field strength. On the Moon, g = 1.6 N/kg.

Explanation:
A sperm cell has a tail 40 micrometers long and a student draws it 40mm long. Calculate the magnification
Answer:
The formula for calculating magnification is:
Magnification = Size of drawing / Actual size
Size of drawing = 40 mm
Actual size = 40 micron meter
Convert 40 mm to micron unit: 40 * 1000 = 40,000 micron
Magnification = 40,000 / 40 = 1000.
The magnification is 1000 X.
This answer means that the drawing is 1000 times bigger than the actual size of the cell.
plz help asap! The activity of many cellular enzymes is regulated by activators and inhibitors. Enzyme activity is also regulated in eukaryotic cells by which of the following mechanisms?
Compartmentalization and restricting enzymes to specific organelles or membranes
Secreting enzymes out of the cell
Limiting the availability of substrates
Changing the primary structure of enzymes
Answer:
compartmentalization and restricting enzymes to specific organelles or membranes
Cellular steroid gradients are produced by the compartmentalization of enzymes into various organelles of a cell, and this might impact how well the various steroid products are balanced. Thus, option A is correct.
What is Compartmentalization?In biology, the biomembrane, or biological membrane, effectively compartmentalizes enzymes by allowing them to perform only certain functions within a limited area.
The enzymes may be located on the membrane surface or inside the defined compartments.
A percentage of the enzymes would likely not work or their ability to catalyze reactions would likely be insufficient if there was just one cellular compartment.
This is because enzymes catalyzing distinct reactions frequently have variable temperature and pH optimums.
Therefore, Compartmentalization and restricting enzymes to specific organelles or membranes.

What factor most affects whether a mutation will be passed to offspring?
ANSWER PLEASEEEEEEE
Answer:
Mutations are only passed on to offspring when they occur in germ cell DNA, which are the cells that create sperm or ova. ... The mutation will be inherited only if it occurred on a chromosome in either the sperm cell or the ova cell out of many that eventually unite to form a zygote.
They are present in all body cells and can be passed down to new generations. Acquired mutations occur during an individual's life. If an acquired mutation occurs in an egg or sperm cell, it can be passed down to the individual's offspring. Once an acquired mutation is passed down, it is a hereditary mutation

How do our bodies have so many different types of cells with different functions?
Please help this is due today and I really need help.
Answer:
Humans are multicellular, complex organisms. The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.
For example:
Cells in the brain may be longer in shape so they can transmit signals more efficiently.
Cells of the heart have more mitochondria because they need a lot of energy.
Cells in the respiratory system are responsible for taking up oxygen and releasing carbon dioxide.
All the cells work together to keep the human body running efficiently.

4. Sunlight, water, and carbon dioxide are environmental factors that affect the rate of photosynthesis?
What would happen to the rate of photosynthesis if producers did not get enough of one or more of these
factors?
Answer:1.Yes plants take in carbon dioxide for "air" they need water to keep hydrated sunlight helps it make food.
2.Then the entire process of photosynthesis would crash. If no carbon dioxide the plant would not be able to breath and die, No water and it dies of thrist and no sunlight and the plant shivers and dies.

Describe the difference between a hot cup of water and cold in terms of thermal energy.
Answer: If you had two cups of water, one filled with hot water and another with cold water, the cold water will retain more molecules. The compounds that make up hot and cold water are the same. One oxygen and two hydrogen atoms make up each molecule. The pace at which the molecules wobble about is the disparity between them.

Using your knowledge of the water cycle, why do you think high sea surface
temperatures correlate to a large amount of water vapor in the atmosphere?
Answer:
Explanation:
The correlation between sea surface temperature and water vapor is that both are driven by seasonal changes. They both increase in the hemisphere during summer. Seasonal changes in water vapor are, however, more evident across the land, largely due to changes in land surface temperature.
