In eukaryotic cells, such as animal cells and plant cells, DNA replication occurs in the S phase of interphase during the cell cycle. The process of DNA replication is vital for cell growth, repair, and reproduction in organisms.
How does biomagnification put a top predator at a disadvantage?*
Answer:
Food is much harder to find the farther up the food chain you go. Toxins and chemicals accumulate in the bodies of everything that was eaten by the food that you eat. Toxins and chemicals bind to the tissue of larger animals better than smaller ones.

Explain the causes of the seasons
pls help
Answer:
Seasons change because of earth's rotation.
Explanation:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere.

Explanation:
An animal that is endothermic and homoeothermic A. uses metabolic energy to regulate its body temperature and maintains a relatively constant body temperature B. has its body temperature determined primarily by the environment, but maintains a relatively constant body temperature C. has its body temperature determined primarily by the environment and has a broad range of body temperature variation D. behaviorally regulates its body temperature and has a broad range of body temperature variation E. uses metabolic energy to regulate its body temperature but has a broad range of body temperature variation
Answer: The correct option is A (uses metabolic energy to regulate its body temperature and maintains a relatively constant body temperature).
Explanation:
HOMOEOTHERMIC animals are also called endothermic animals. They are the warm blooded animals which uses heat energy generated metabolically to regulate and maintain a relatively constant body temperature. Examples of animals that are endothermic include the birds and mammals.
The temperature which they maintain is deep inside the body and not the skin temperature.
Also the temperature of a body is affected by the heat it gains and losses. The body gains heat mainly:
--> by absorbing it from its surroundings
--> from the heat released during the catabolic reaction that occur all the time in the body cells.
--> by conduction, convection and radiation from the surface of the body
--> through evaporation, especially of sweat and
--> in the air that is exhaled and urine that leaves the body.
Under normal circumstances, the heat the body gains is balanced by the heat it loses. A RISE in body temperature stimulates the following processes to get rid of excess body heat:
--> A decrease in metabolic rate: the body slows down its activities to decrease the metabolic rate. This reduces the heat released by metabolic reactions, hence minimizing heat production within the body.
A FALL in body temperature stimulates the following processes to produce and conserve heat:
--> increasing metabolic rate: The body increases its metabolic rate, especially that of the liver, to produce more heat

What is nuclear energy?
A. the energy released in nuclear reactions
B. the energy it takes to bond elements to form compounds
C. the energy holding the particles in a nucleus together
D. the energy that causes the water in a pot on the stove to boil and form steam
Answer:
C
Explanation:
Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe, and energy is what holds the nucleus together. There is a huge amount of energy in an atom's dense nucleus.

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because O she did not believe the new formula helped plants grow better than the old formula. O it was necessary to see data from more plants before the conclusion could be accepted. O it was necessary to have tested the fertilizer on different kinds of plants. O she thought he should test additional fertilizer formulas on the same two plants.
Answer:

Which statement best describes the pioneer organisms involved
in ecological succession?
Select one:
Pioneer organisms are restricted to desert biomes.
Pioneer organisms do not require sunlight.
Pioneer organisms are the last organisms to appear.
Pioneer organisms modify the environment.
Answer: Pioneer organisms modify the environment.
The statement that best describes the involvement of pioneer organisms in ecological succession is as follows:
Pioneer organisms modify the environment.Thus, the correct option for this question is D.
What is Ecological succession?Ecological succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Pioneer organisms are those organisms that arrive first in any ecosystem which is bare. The pioneer species are always found to be present in the bare area. The organisms that are the last organisms to appear known as climax organisms.
Pioneer organisms modify the environment in such a way that makes the bare atmosphere a little bit improved with respect to the need of other organisms.
Therefore, the correct option for this question is D.

Down syndrome is a common genetic disorder that is caused by having an extra copy of chromosome 21. Which method will show whether or not a baby has down syndrome?
a. Karyotype
b. Family history
c. Genetic survey

Answer:
a. Karyotype
Explanation:
Karyotypes describe the chromosome count of an organism, so all the chromosomes would be in front of you, and it'd be easy to tell if there are 2 or 3 chromosome 21.
What is the speed of a wave with a wavelength of 0.5 m and a frequency of 20 Hz?
Answer:
You multiply 0.5 by 20 which will give you 10 your answer is 10
the speed of a wave with a wavelength of 0.5 m and a frequency of 20 Hz is 10
what is speed ?Speed can be referred as the ratio of distance to the time in which the distance was covered which is a scalar quantity as it has only direction and no magnitude.
The speed is represented as s=d/t, Where, s is the speed in m.s-1, d is the distance traveled in m, t is the time taken in s
There are four types of speed like Uniform speed, Variable speed, Average speed, Instantaneous speed
Uniform speed is where the object covers equal distance at equal interval of time, variable speed is defined as when the object covers a different distance at equal intervals of times.
Instantaneous speed is defined as an object is moving with variable speed, then the speed at any instant of time is known as instantaneous speed.

If two populations of people share the same DNA "spelling difference" (i.E., mutation), what does this mean about these two populations?
Answer:
It could mean that those two populations could be common ancestors because the spelling differences are the same
Explanation:
The similar spelling variations between the two populations could imply that they share common ancestry.
What is DNA?Deoxyribonucleic acid, or DNA, is the name given to the genetic material carried by humans and nearly all other species. An individual's DNA is present in nearly all of their cells.
Nucleotides are the molecular building components that make up DNA. A phosphate group, a sugar group, and one of four different nitrogen bases make up these building components. Nucleotides are joined into chains and the locations of the phosphate and sugar groups are switched to form DNA strands.
Every cell in the body has DNA in its nucleus. Groups of these firmly bound fragments make form chromosomes. The majority of people possess 46 pairs of chromosomes, or 23 pairs per pair.
Thus, The similar spelling variations between the two populations.

The abyssal zone, which lies between 4,000 and 6,000 meters (13,000 and 20,000 feet) below the surface, is the deepest region of the ocean. So, option B is the answer.
The region of the ocean that lies beyond the continental shelf is commonly referred to as the oceanic zone. The sunshine zone, twilight zone, midnight zone, and abyssal zone are the four vertical zones that make up the open ocean.
Abyssal zone is characterized by high pressure, low temperatures, and very little light.
Kelp forest is found in shallower areas, often between 20 and 100 meters deep and Coral reefs are located in tropical, shallow waters.
