Answer:
Genetic Variation
Explanation:
Mutations, gene flow, and sexual reproduction causes genetic variation. Mutatio is the changes in the sequence of genes in the DNA. Gene flow is the movement of genes from one organism to another, and sexual reproduction, is where new combinations of genes are created.

PLEASE HELP!!!
In the space below, discuss some of the advantages and disadvantages of asexual and sexual reproduction. Compare and contrast individuals that are sexually and asexually reproduced. Use complete, meaningful sentences to explain the information you give as your answer.
Answer:
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population

What part of a nuclear fuel rod is reused for nuclear weapons after its spent?
A-Uranium
B-Plutonium
Answer:
Uranium
Explanation:
I had it on a quiz
Plutonium is the wasted portion of a nuclear fuel rod which is reused for nuclear weapons. So, the correct option is B.
What is Plutonium?Plutonium-239 is an explosive substance that may be used as nuclear reactor fuel or as a nuclear bomb explosion. It is created from uranium-238 in nuclear reactor fuel rods via a process known as nuclear transmutation. When uranium-238 receives a neutron, it is transformed into plutonium-239, which can fission and release energy.
The plutonium-239 produced in a nuclear reactor is utilized as fuel, together with uranium-235, to continue the nuclear chain reaction. The plutonium-239, on the other hand, may be extracted from spent nuclear fuel and refined for application in nuclear weapons. Nuclear reprocessing is a contentious problem due to the concerns of nuclear proliferation and the possibility for nuclear terrorism.
Therefore, the correct option is B.

How does air flow when a low-pressure center occurs in the atmosphere?
Answer:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

Which of the following statements is NOT true about the stratosphere?
A.
The stratosphere contains a layer of ozone.
B.
The stratosphere absorbs ultraviolet radiation which protects life on Earth.
C.
Commercial jet aircraft avoid the stratosphere due to the high turbulence there.
D.
The stratosphere is above the troposphere and below the mesosphere.
Answer:
Explanation:
After doing some g0ogle searches, I believe C is incorrect. Stated from g0ogle, "Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. " It seems to me that jets avoid the troposphere, which is below. <3

The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

A sugar farm near the coast of Florida applies a nitrogen based fertilizer to their soil three times a year. When rain falls on these fields after it has been fertilized some of the fertilizer runs off into the ocean causing the nitrogen levels in the water to increase. The increase levels of nitrogen can lead to many ecological effects beginning with the rapid growth of algae. This process is known as eutrophication.
How can eutrophication affect other organisms in the water?
Group of answer choices
The algae provide food for fishes and other organisms, leading to decreased algae populations.
The oxygen in the water is used up as algae is decomposed, reducing the amount available to other organisms.
The water becomes better able to support aerobic organisms.
The extra nitrogen provides additional food for the other organisms, increasing their population.
Answer:
The algae provide food for fishes and other organisms, leading to decreased algae populations
Explanation:
Excessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. ... Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants.

The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
What is Photosynthesis?Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
Light-dependent reactions and light-independent reactions are the two main stages of photosynthesis. The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine.
Therefore, The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.

A high rise condominium is planned for a barrier island that lies off the southwest coast of Florida. Which of these predictions could be made about the impact this construction will have on the sustainability of the coastal ecosystems?
Group of answer choices
Predators will abandon the habitat as humans are the top predator in any ecosystem.
The ecosystem will be destabilized as abiotic resources like available space are reduced.
The costal ecosystem populations will decline until new species evolve that are adapted to live new humans.
Key species found on the barrier island will move to a new habitat.
Answer:
The ecosystem will be destabilized as abiotic resources like available space are reduced.
Key species found on the barrier island will move to a new habitat.
Explanation:
Due to living of humans on the barrier Island with adversely affected the organisms present on that Island because the loss of habitat occur due to living of humans and the important species migrated to other habitats where no humans are present. So this action greatly change the environment of barrier Island and the ecosystem will be destabilized.
