A)
The rotting remains of plants add to the fertility of the soil.


B)
The soil becomes so fertile that eel grass is replaced by other plant species.


C)
The roots from plants help stabilize the sediment, keeping it in place.


D)
The concentration of salt becomes so high that all plant life is destroyed.

B)
These two species evolved under similar environmental pressures.
C)
These two species do not have a common ancestor, but evolved from

identical phenotypes.
E)
These two species share a more recent common ancestor than they do with
other mammalian species.

Answers

Answer: a and b

Explanation:

i just took it

The relationship between these two mammalian species is that Convergent evolution occurred in these two mammalian species. That is option A.

What is Convergent evolution?

Convergent evolution is the type of evolution where distantly related organisms evolve similar traits to adapt to similar environmental conditions.

The marsupial mole and the placental mole are distant species with similar features.

Therefore, the relationship between these two mammalian species is that Convergent evolution occurred in these two mammalian species.

Which of the following is an example of genomic imprinting in humans? Which of the following is an example of genomic imprinting in humans? A random pattern of autosomal allele inactivation is observed. In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed. The maternal and paternal alleles of a gene pair are both expressed. Human males have only one Y-chromosome and one X-chromosome. One of the two X-chromosomes in females is randomly expressed and the other is repressed.

Answers

Answer:

In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed.

Explanation:

Genomic imprinting is an epigenetic phenomenon where alleles are differentially expressed depending on their parental origin (for example, paternally expressed when it is inherited from the father). Genomic imprinting is controlled by epigenetic modifications (for example, DNA methylation, histone acetylation, etc) which works together to preferentially activate the expression of the allele inherited from one parent and simultaneously silence or “​imprint” the expression of the allele inherited from the other parent. In humans, an example of genomic imprinting is the case of the insulin-like growth factor 2 (Igf2) gene, which is maternally imprinted (repressed), thereby this gene is only expressed from the paternal allele.

Answers

Answer:

Qualitative observations are those that cannot really be counted or measured by empirical figures, but are rather described by the features they have such as their color or taste.

Quantitative observations can be measured and counted by empirical figures  i.e. numbers such as age and temperature. Number operations such as addition can be performed on them as well.

Which of the following best explains the evolutionary basis of human skin color? two parents who are heterozygous for each of the alleles have a greater probability of having a child with medium skin than one with very light or very dark skin in a diverse population, the distribution of the trait will be a bell curve, so most people will fall in the middle the inheritance of the alleles from each parent is completely random but in a population there may be natural selective pressure from the environment to favor different levels of expression multiple genes and multiple alleles each have an additive effect on how intensely the trait is expressed.

Answers

Answer:

From the given Options, Option  C is correct.

the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression

Explanation:

The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.

The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option  C.
