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.

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

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.

A V-shaped valley, like the one shown, is a narrow valley with steep sides that appear to form the shape of a "V." Which statement best explains how this type of valley is typically formed? A) They are formed by weak streams, slowly wearing away rock over time. B) They are formed by forceful streams, cutting down into rock over time. Eliminate C) They are formed by massive mountain glaciers slowly moving down slopes. D) They are formed by forceful winds moving between the walls of the valley.
Answer:
The answer is B
Explanation:
In the picture there is 2 streams also I took the question myself for you and the answer was B.
This type of valley is typically firmed by forceful streams cutting down into rock over time. So the correct option is B.
What is a valley?Valley: an extended depression on the surface of the Earth. Rivers are most often responsible for draining valleys, which can be found on relatively level plains or in between groups of hills or mountains. Rift valleys are those valleys created by tectonic activity. Gorges are the name given to similar-looking, extremely deep, narrow valleys. Despite being possible in different geological contexts, both of these latter kinds are frequently cut in strata with a flat topography.
There is potential for the land surface to develop into the well-known patterns of hills and valleys wherever there is enough rainfall. In fact, there are hyperarid regions with little activity. There are also geomorphological conditions where water cannot concentrate on the ground surface due to the permeability of the rocks or sediments causing excessive infiltration.
Therefore the correct option is B.

PLS ANSWER QUICK What do you think would happen to each species if the water became too cloudy for sunlight to penetrate?
Answer: Turbidity blocks the sunlight that plants need to produce oxygen for fish and other aquatic life. ... One effect is an increase in rooted aquatic plants, since sunlight can now penetrate to greater depths.
Explanation:
PLS ANSWER How is sunlight important in your life? Describe some of the positive and negative effects of sunlight.
Answer:
Sunlight is important in my life because you need it if you have a plant and you want to take care of the plant.Postive effects of sunlight is Sun water and needing health
Answer:
I know one reason is that plants need sunlight, and without plants we would all die. This is because plants need sun, and if we didn't have plants, we would be robbed of that resource, and then animals who eat the plants would die, so meat would be taken from us as well and we would all DIE.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
competition
random chance
being the luckiest
Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
Scientists find evidence of a large meteor impact on the coast of the Yucatán Peninsula in Mexico. What can the scientists most likely expect to find in the layers of rock that are about the same age as
the impact?
evidence of the mass extinction of many species
evidence of a gradual change of one species over time
evidence of a rapid change in one species
evidence of the stability of many species over time
Answer:
evidence of a gradual change of one species over time
Explanation:
Scientists can most likely expect to find evidence of the mass extinction of many species in the layers of rock that are about the same age as the impact. Therefore, option (A) is correct.
What is mass extinction?Mass extinction refers to a widespread and rapid decrease in the biodiversity on Earth, where a large number of species become extinct within a relatively short period of time.
The impact of a large meteor on the Earth can cause widespread destruction and have far-reaching consequences, including the extinction of many species. The impact can cause a global environmental crisis, which can include the release of massive amounts of dust and debris that block sunlight, leading to a drop in temperature and changes in climate.
These changes can have catastrophic effects on living organisms, particularly those that rely on photosynthesis for survival. As a result, scientists can expect to find evidence of the mass extinction of many species in the layers of rock that are about the same age as the impact.

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.
