Mutations are important because they bring about
A) death if the organism in which they develop
B) genetic variation needed for a population to evolve
C) benefits for the individual, not for the population
D) hardey-weinberg equilibrium within a population

Answers

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.

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.

Why does herding help a horse survive better?

Answers

Answer:

In natural environments, horses typically live in relatively stable social units. Horses live in herds so that they are able to fulfil their basic needs, which are to avoid danger or harm, and to reproduce successfully and bring up healthy foals.

Horses live in herds so they can protect themselves from danger, they would have a less chance of getting hurt if there is more of them. Another reason is because they are better able to fill there needs by being in a herd, they don’t like being alone and they are social animals. Horses are happier when they are in a herd.

Damage to the auditory nerve or to the hair cells in the inner ear results in
A. Ménière's disease
B. sensorineural hearing loss
C. conductive hearing loss
D. otitis media

Please select the best answer from the choices provided

Answers

Answer:

B. sensorineural hearing loss

Explanation:

Damage to these hair cells results in decreased hearing sensitivity, and because the inner ear hair cells cannot regenerate, this damage is permanent.

Damage to the auditory nerve or to the hair cells in the inner ear results in sensorineural hearing loss. Thus, the correct option is B.

What is the Auditory nerve?

The auditory nerve may be defined as a cluster of nerve fibers that transport hearing information between the cochlea and the brain.

When the auditory nerve or hair cells are damaged due to any injury or other reasons, it can lead to a reduction in hearing sensitivity.

The cells of this region are unable to regenerate, and hence this damage will remain permanent, and sensorineural hearing loss will result in this scenario.

Therefore, the correct option for this question is B.
