Nutrients enter a cell DOWN the concentration gradient by the process of DIFFUSION.

This process of absorption of digested nutrients mainly uses diffusion (only some times active transport), which is a kind of method of material transportation where the net movement is fluid will flow from a region of higher concentration to the region of lower concentration, due to its original random movement.
Therefore, this net movement can be described as down the concentration gradient, and this process is diffusion.

In two or more complete sentences, compare species diversity and genetic diversity, and glve an example for each one.
Bingel [31]

Answer:

Diversity in the genetic characteristic or traits present in a species throughout populations of particular species called genetic diversity. Genetic diversity deals with the number of alleles and genes found between individuals. It is responsible for the adaptation and distribution of species.

Species Diversity is the relative abundance of species found in a given biological organization in a community and interacts with biodiversity by changing biotic factors.

A man with normal vision marries a color-blind woman. Red-green color blindness is an X- linked recessive disorder. They have a
jeyben [28]

Answer: The probability is 100%.

Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:

  • If it is a boy, he inherites the chromosome Y from his father and X from his mother;
  • If it a girl, she inherites X from her father and X from her mother;

In the question, the woman is color-blind, which means she carries the recessive alleles: X^{d}X^{d}

The man, on the other hand, is normal, so his X-linked genotype will be: X^{D}Y.

Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one X^{d} from her mother and one X^{D} from her father.

So, the daughter's genotype can only be heterozygotic  X^{D}X^{d} in other words, the probability is 100%.
