andrey2020 [161]

Hello. The chart mentioned in the question above is attached just below.

Answer:

A) has increased with increasing human population

Explanation:

As you can see in the graph below, the line that indicates the number of endangered species increases as the line that represents the increase in the human population increases. This means that the number of extinct species has increased with the increase in the human population.

This is because with the increase in the human population, there is a growing need for natural resources, in addition to increasing the need for cities to expand. All of this results in greater deforestation and extraction of natural resources, which ends up causing an increase in the factors responsible for the extinction of animals.

In a hypothetical breed of dogs, coat color is controlled by two genes. There are six different coat colors in this breed: black
Andru [333]

The correct statements are C and F.  

There are two elementary types of pigments, which are responsible for the color of the coat, that is, phaeomelanin and eumelanin. Eumelanin is basically a black pigment and cells produced by it are responsible for a black dog coat color. However, there are genes that result in changes in eumelanin to produce brown, gray, or dusty pale brown coat color. The genes responsible for this change leads to the modifications in the creation of the eumelanin in the cells.  

Due to this reason, dusty pale brown and gray dogs are considered as dilutes. Eumelanin can also be witnessed in eyes and nose. On the basis of the genes in dogs, the nose can be brown, black, dusty pale brown, or gray. The other pigments, that is, phaeomelanin is red. Most of the dogs exhibit both phaeomelanin and eumelanin, and the manner in which these two pigments get amalgamated is controlled by agouti locus.  

The white color in dogs is not stimulated by any pigment, but by the cells that do not possess the capability to produce any kind of pigment. The entire animal can be affected in a different manner to albinos, or it can be restricted like the white coat patterns.  

The correct statements regarding the mode of inheritance of the coat color genes are:  

1) One of the genes modifies the expression of the other.  

2) One of the genes is autosomal, and the other is X-linked.

. Daughter cells produced when cells undergo mitosis are genetically _______, and daughter cells produced when cells undergo mei
Radda [10]
Answer; 
D. identical, diverse
Daughter cells produced when cells undergo mitosis are genetically identical, and daughter cells produced when cells undergo meiosis are genetically diverse.

Explanation; 
Meiosis and mitosis are the two major types of cell division. Mitosis takes place in the somatic cells (body cells) in which parent cells undergo division to yield daughter cells that have similar number of chromosomes as the parents. Meaning the daughter cells are identical to the parent cells in terms of genetic material composition.
Meiosis on the other hand, involves division in the germ-line cells in which parent cells divides to yield daughter cells that contain half the number of chromosomes as the parent, meaning that they are not genetically identical, however they re genetically diverse due to the process of crossover and recombination.
