Which of the following are NOT correct based on Darwin's theory of evolution?

Black_prince [1.1K]

Answer:

D variations in individuals are not heritable

Explanation:

Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.

Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.

Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.

<span>Actually here in this case, the nurse actually expects that the patient may get relieved from any sorts of nerve pain and tingling in any parts of the body, by receiving gabapentin, which is also a anticonvulsant OR antiepileptic drug, hence it can used for treating other nerve problems along with seizures and may also be used at initial stages for prevention of any medical complications.</span>

The ABO blood group assorts independently of the Rhesus (Rh) blood group and the MN blood group. Three alleles, IA , IB , and i,

Eva8 [605]

Answer:

Part 1:

The mother’s genotype is ii, rr, MN

The father’s genotype is IAIA/IAi, Rr, MM

Part 2:

Approximately 1/32 (3.125%) of children can be expected to have the stated blood types.

Explanation:

Part 1:

The mother has blood types 0, Rh- and MN. Therefore, her genotype has to be ii, rr, MN.

The father has ABO type A. His ABO genotype may therefore be either IAIA or IAi, as both are compatible with type A offspring with a type 0 mother. His Rh genotype must be rr, since his Rh- child necessarily has to have inherited one r allele from each parent. Finally, his MN genotype has to be MM since both alleles are codominant.

Part 2:

Using the given data, we build the following Punnett chart:

IA R N IA r N i R N i r N

IA R M

IA R N

IA r M

IA r N

IB R M

IB R N

IB r M X

IB r N

Note that, of all 32 possible combinations, only a single one of them (marked with “X” produces a genotype which matches the desired blood type, as follows:

genotype: IBi, rr, MN

blood type: B, Rh-, MN

Explain how seasonal fires benefit grassland ecosystems.

Soloha48 [4]

Answer:

Without fires, there would be no life on Earth . Fires are key to maintaining the proper oxygen concentration in the atmosphere; fire regulates the carbon cycle and life, as we know it, is based precisely on carbon

Explanation:

Although we tend to think of fires as a human invention that kills plants, animals, people, fire, as with rain or wind, is an essential natural component, basic to maintain the planet's biodiversity.

As for example, grassland ecosystems are also benefited by the same fires that allow renewal, and generate natural sustainability on the earth through the carbon cycle.
