what controls the role of gravity in space
Answer:
Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. ... It can also cause life-destroying asteroids to crash into planets.
Explanation:
How does oxygen concentration in the atmosphere correlate with animal diversity?
Answer:
Oxygen burns the food within their bodies and releases energy for various activities and thus it helps animal to be alive. to use it in respiration. Animals need oxygen (O) to survive. In fact, all organisms need oxygen to complete the process to burning glucose for fuel.

Which statement correctly defines asexual reproduction?
A. Asexual reproduction has 1 parent with similar offspring
B. Asexual reproduction has 1 parent with identical offspring
C. Asexual reproduction has 2 parents with similar offspring
D. Asexual reproduction has 2 parents with identical offspring
Answer:
A.)
Explanation:
We know that asexual means one. In this case, it would be A
., because there is one parent producing the cells. There may be some differences, which would make similar offspring, not identical offspring. So the answer would be A.) :) Hope this will help!

About how many genes are in every human cell?
Answer:
In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes.

7. Once you have taken a bite of an apple, which of the following represents the correct pathway of its nutrients?
A. circulatory system → cell → digestive system
B. digestive system → circulatory system → cell
C. cell → digestive system → circulatory system
D. circulatory system → digestive system → cell
Once you have taken a bite of an apple, digestive system → circulatory system → cell represents the correct pathway of its nutrients. The correct option is B.
What is nutrient?Nutrients are substances found in food that drive biological activity and are therefore necessary for the human body.
To begin the digestion process, the nutrients in the apple are first broken down by the teeth in the mouth and mixed with saliva.
After swallowing, the food bolus travels down the oesophagus to the stomach, where it is further broken down by stomach acid and digestive enzymes.
The nutrients are then absorbed into the bloodstream via the small intestine walls and carried to the liver via the circulatory system.
The nutrients are distributed to the cells throughout the body by the liver to be used for energy and other functions.
Thus, the correct option is B.

Which of the following would change the allele frequencies of a population?
A)Lack of mutation in the DNA
B)Mating is random with no selection occurring
C)A population on an island remains isolated and no one leaves or moves on the island
D) All of the answer choices would change allele frequencies of a population.
Answer: option B.
B)Mating is random with no selection occurring
Explanation:
This will cause change in allele frequency because it's a genetic drift which is the change in the frequency gene variant that is common in a population due to random sampling or random mating. When this occur it lead to a change in percentage or incidence of gene variant in a population since there is random sampling without any selection.
Mating is random with no selection occurring, which would change the allele frequencies of a population.
What would increase the allele frequency in a population?Natural selection can drive microevolution, or a difference in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations.
Thus, option"B" mating is random with no selection occurring.

A population of wolves migrates north in search of food. As the wolves travel, they enter a region that
has long, snowy winters. Some of the wolves have an allele that gives them white coats. This makes them
better able to sneak up on prey. Is this an example of natural selection? Explain.
Answer:
Yes
Explanation:
Natural Selection is not only when genes and alleles are passed down to children but also when your genes better adapt to your surroundings and the environment this shows natural selection

What is the difference between aerobic and an-aerobic cellular respiration ?Cellular respiration is just opposite to photosynthesis where glucose break down to produce energy in the form of adenosine triphosphate or ATP.
If It occurs either in presence of oxygen called aerobic respiration and in absence of oxygen called anaerobic respiration.
Aerobic respiration where organism combine oxygen with food substances and produce biochemical energy in the form of ATP, release carbon dioxide, and water as by product.
It occurs in inner membrane of the mitochondria.
Example is glycolysis.
Anaerobic respiration occurs in the absence of oxygen, involve break down of sugar into lactate and it occurs in Cytosol of cell.
Fermentation is example of anaerobic respiration.

Which evidence best supports is the theory that organisms, such as whales , have common ancestry and have evolved ? Select all that apply
Answer:
Another evidence of evolution is the convergence of form in organisms that share similar environments.
Fossil record , comparative anatomy, DNA and molecular evidence and biogeography supports the theory of evolution.
What is theory of evolution?The theory of evolution is a scientific explanation for how living species have evolved over time and how new species have emerged. The hypothesis is predicated on the notion that all living things have a common ancestor and have evolved over time by natural selection.
Natural selection is the process through which specific features or characteristics, based on their capacity to aid people in surviving and reproducing in their environment, become more or less prevalent in a population over time.
The idea of evolution is largely regarded as the best explanation for the variety of life on Earth and is supported by a large amount of evidence from disciplines like genetics, palaeontology, comparative anatomy, and biogeography.
