Answer:

C. there is a prominent primary root from which secondary roots branch out

Explanation:

A tap root system is a mass of roots that comes from a radicle of the embryo. It consists of a tap root, secondary roots, tertiary roots, and rootlets; for that reason, it is said that is a primary root from which secondary roots branch out. Moreover, the primary root is known as a tap root; it is the most prominent, thickest, and largest of all. The secondary and tertiary roots are the branches of the first and second order.

Answer:

The cell membrane of malignant cells contains proteins called tumor-specific antigens.

Explanation:

The cell membranes are affected in cancer cells, which alters fluid movement to and fro from the cell. The cell membrane of malignant cells has the tumor-specific antigens proteins, lowered fibronectin, a cellular cement and a weak or fragile chromosomes.

They exhibit pleomorphism I.e. they have a large and intermittently shaped nuclei.

If the tasmanian devil has ______, then it is a boy. If the tasmanian devil

Llana [10]

Answer:

If the tasmanian devil has XY, then it is a boy. If the tasmanian devil has XX, then it will be a female

Explanation:

Just like other mammals, the tasmanian devil is a marsupial, that possess 14 chromosomes including the sex chromosomes with the male being heterogametic (XY) and the female producing two similar chromosome (XX). Thus, if the tasmanian devil has XY, then it is a boy. If the tasmanian devil has XX, then it will be a female, just like in the human normal chromosomes.

A population of 150 fish have two alleles for the size of a black spot on their sides: large spot alleles and small spot alleles

MAVERICK [17]

Answer:

1. genetic drift; 2. natural selection; 3. gene flow; 4. natural selection

Explanation:

1. A fish net captures twenty fish, all who happened to have large spots: 

The mechanism of evolution that is playing out in this situation is most likely genetic drift. Genetic drift occurs when a random change occurs, resulting in the selection of a number of individuals by chance, rather than based on their level of fitness. The fish with large spots allele were selected against by chance, not necessarily because the fish with the small spot alleles were better fitted.

2. Small spotted fish escape from predators better:

The situation here is natural selection. The small spotted fish possess a greater fitness as they become well adapted to escaping from predators better than the large spotted fish, which gives confers on them a greater fitness to be selected for against the large spotted fish.

3. 15 large spotted fish move into this population:

The movement or introduction of new individuals i nto a population is what is referred to as gene flow in evolution, which is another mechanism of evolution that changes the allele frequency of the original population.

4. Fish-eating birds catch large spotted fish more easily:

This is another example of natural selection. The small spotted fish possess a greater fitness which makes them not easily preyed upon by Fish-eating bird easily, compared to large spotted fish. Natural selection favors the fish with small spotted alleles against the large spotted fish, and as a result, more small spotted fish would survive and reproduce more offspring with the small spotted alleles compared to those with large spotted alleles.
