Which of the following are benefits of genetic diversity? Select all that apply.
DanielleElmas [232]

Answer:

<u><em>The benefits of genetic diversity include:</em></u>

  • 2- species survive despite negative mutations
  • 4- species adapt to ever-changing environments
  • 5-gene pool is strengthened

Explanation:

Mutations resulting from errors within gene replication frequently accumulate within species, becoming more stable over time. They lead to other forms of the same genes called alleles.

Several alleles within a population's gene pools leads to higher diversity. These may become beneficial,  as the environment of the organism changes.  

Mutations that confer benefits tend to help organisms survive and produce offspring, passing on these genes. However, some mutations may be deleterious/harmful and fatal. High diversity reduces the deleterious effects of some mutations on a population for a stronger gene pool i.e. the species survives.

Imagine that a researcher claimed to have created a genetically modified plant that produces twice as much energy as it harnesse
Virty [35]
According to the Law of Conservation of Energy, energy is neither created nor destroyed. Technically, it is impossible for the plant to produce energy twice this input. It could only be possible if an external energy is required to create a reaction that would create more energy. This external energy could in the form of energy or another chemical containing potential energy.

A species of fly lives in a canyon. Some of the flies prefer the side that gets sunlight during the day, while others prefer the
Dvinal [7]

Answer:

D. habitat preference

Explanation:

Habitat preference is one of the driving forces for ecological speciation that does not allow interbreeding between the members of a species. In habitat preference, some members of a species have a different preference for habitat than the others. They live in different habitats and do not interbreed. Over generations, these two populations of a species living in different habitats develop genetic variations and interbreed with the members of their own populations only. Gradually, these two populations would develop reproductive isolation and would evolve as two different species.

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?
Wittaler [7]

Answer :B. By changing the shape of the enzyme's active site.

check the attachment

Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the  active site.

On binding, it disrupts the  normal hydrogen bond and hydrophobic   interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and   ACTIVE SITE of the  enzyme (changed it shape).

Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit  for binding with the substrate, therefore  the efficiency  is reduced. No substrate-enzyme complex, and hence no substrate-product  complex for the release of  products, this brings down the turnover rate and eventually

<u>the rate of reaction of the enzyme</u>

Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
