Hello!!! Princess Sakura here ^^
Explanation:
Genetic variations is an advantage to a population because it allows them to adapt to their environment.
Example: The arctic fox has brown fur in the summer but in the winter it grows in white fur. That's because it needs to blend in with its surroundings.

. the negatively charged part of an atom
Answers
Answer:
Electrons are the negatively charged particles of an atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The mass of an electron is almost 1,000 times smaller than the mass of a proton.

Study Finds Aardvarks Suffering as African Climate Heats Up
Little is known about Africa's elusive aardvarks, but new research says they are vulnerable to climate change like many other species.
Hotter temperatures are taking their toll on the aardvark, whose diet of ants and termites is becoming scarcer in some areas because of reduced rainfall.
Drought in the Kalahari Desert killed five out of six aardvarks that were being monitored for a year, as well as 11 others in the area.
The aardvarks' body temperatures plummeted during the night because they were not getting enough energy from diminished food sources. They tried to conserve energy by looking for insects
during the warmer daytime, but their efforts to adapt could not save them
Researchers said some birds, reptiles and other animals use aardvark burrows to escape extreme temperatures, reproduce, and hide from predators. They could have fewer refuges available ir
aardvark populations shrink because of rising temperatures, they said.
The aardvark, which lives in many parts of sub-Saharan Africa, is identified as an animal of "least concern on an international "red list of threatened species. There are no indications that the
population is changing significantly in southern Africa, though it is speculated that numbers may be declining elsewhere because of habitat destruction, the bushmeat trade and other factors.

Which of the following best identifies the author's claim?
Answers
The option that identifies the author's claim is B. Aardvarks are a keystone species and their decline could have a trophic cascade effect on the ecosystem.
The claim of an author simply refers to what the author is trying to point out. Here, the claim of the author is that aardvarks are a keystone species and their decline could have a trophic cascade effect on the ecosystem.
The author stated that aardvarks are vulnerable to climate change like many other species and this could lead to their reduction. Some birds, reptiles and other animals use aardvark burrows to escape extreme temperatures, reproduce, and hide from predators. Therefore, the reduction of aardvarks will have a negative effect on the population of such animals.

They are a keystone species, aardvarks' extinction might cause an ecosystem-wide cascade of trophic levels. The correct option is B.
Thus, An author's claim simply refers to what the author is attempting to make a point about. Aardvarks are a keystone species, according to the author, and their extinction could have a negative trophic cascade effect on the environment.
According to the author, aardvarks, like many other species, are susceptible to climate change, which could result in a decline in their population.
Aardvark burrows are used by some birds, reptiles, and other creatures as a refuge from harsh weather, a place to mate, and a place to hide from raptors. Aardvark populations will therefore be negatively impacted by the decline in aardvarks.
Thus, They are a keystone species, aardvarks' extinction might cause an ecosystem-wide cascade of trophic levels. The correct option is B.

how does carbon from the carbon cycle leave the ecosystem?
Answers
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

Osmosis is the diffusion of water across a membrane, where the water at a higher concentration naturally moves to the side of the membrane that has a lower concentration to even it out. Active transports move any ions or molecules, not just water, and require energy to move in and out of a membrane.

Answer:
B) genetic variation needed for a population to evolve
Explanation:
Mutations are important because they bring about the genetic variation needed for a population to evolve.
Mutation brings about changes in the DNA sequence of an organism. Most times, mutation results when an organism tries to adapt and evolve to unfavorable conditions. Mutation can originate from mistakes in DNA sequencing. It can also be due to environmental influences.Fill in the blank lines in the diagram above to label the two types of connective tissue
