The correct answer is - b) parasitism.

The kudzu is a plant that has adapted to get stuck to the other plants, usually trees and bigger shrubs, and get nutrients and water through them. In this way, the kudzu shows elements of parasitism, as it is using a host plant in order to satisfy its needs.

The native plants and shrubs will have a big problem with an introduction of the kudzu in their environment. They will not have a defense mechanism, and the kudzu will spread out very quickly and suck the nutrients and water out of them, hindering their growth and even killing them over the coarse of longer period of time.

This would be a prime example of parasitic relationship between the kudzu and the native plants.

The traits for blood type and Rh are the result of the presence or absence of particular on the erythrocytes.g
just olya [345]

Answer: Antigens

Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).

Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.

What percent of one’s daily caloric intake should come from carbohydrates?
NISA [10]
This answer will vary a lot, depending on who you will ask. If you're asking proponents of the LCHF (low carbs, high fat) diet, they would say you should reduce your intake of carbohydrates down to around 10 to 20 percent, making either A or C your desired answer.

If you would ask people who propose the current nutritional guidelines as the best way of eating, the amount of caloric intake that should come from carbs according to them would be more in the range of around 40%, making B the correct answer.

There isn't really any clear cut answer here.

Arrange the order of events for the internalization of LDL particles into cells:
ElenaW [278]

Answer:

The correct answer is "5-1-3-2-4".

Explanation:

Internalization of LDL particles into cells, is needed to form the intracellular vesicles known as endosomes. The order of events that allow for this process are:

5) LDL receptors migrate to the cell surface and cluster in clathrin-coated pits. Clathrin acts directing the receptors to the cell membrane region where endosomes are formed.

1) A combination of cholesterol and apolipoprotein binds to LDL receptors and becomes internalized as endocytotic vesicles. Once the receptors are in the proper cell membrane region, cholesterol and apolipoprotein are bound and internalized.

3) Several endocytotic vesicles fuse to form an endosome.

2) The environment of the endosome becomes acidic, which causes the LDL to dissociate from its receptor; additionally, the endosome fuses with a lysosome. LDL should be dissociated from its receptor since it is going to be degraded in the following step.

4) The LDL particle is degraded by the lysosome. This takes place after endocytosis, when LDL particles are transported into lysosomes once they are fused, cleaving the cholesterol esters into cholesterol and fatty acids.

When the DNA molecule folds, coils and super coils to fit in the cell what structure does it form?
Alexeev081 [22]

Answer:

<h2>A. Chromosome</h2>

Explanation:

In intermediate phase of cell cycle, DNA replication occurs (in S-phase), so in inter phase, DNA become unfolded and in relaxed state and is available for replicating machinery.

When cell enter into prophase, DNA folds, coils and super coils and finally become in condensed form, which can be seen by microscope.

So this compact form of DNA is called as chromosome.

In humans. there are total 46 chromosomes.
