jok3333 [9.3K]

Answer:

The main measure that must be taken to alleviate this situation is the proper disposal of garbage in the community in which Dino lives.

Explanation:

Inadequate disposal of garbage can cause a series of very serious illnesses and accidents to the entire community, which reinforces the need for all residents of a community to promote the proper disposal of waste. This is not happening in the community where Dino and his family live.

The inadequate disposal of garbage can contaminate the water and food of the community, causing diarrhea in Dino. This garbage also caused the accumulation of standing water, allowing the dengue mosquito to develop and infect his sister. In addition, garbage has created a suitable environment for maleficent microorganisms, such as the bacteria that causes tuberculosis.

If crossing over did not occur, how could the passing on of physical features be affected?
kupik [55]

Answer:

<em>If crossing over did not occur there would be no diversity among organisms.</em>

Explanation:

Crossing over and independent assortment are the two phenomena of meiosis by which genetic and physical diversity occurs. If crossing over did not occur then there would not be changes in the physical features of children. No physical diversity would be produced. Children would have the same physical features as the parents. Each chromosome would be identical to one of the parents and hence there will be reduced variations.

Describe how an allosteric regulator can regulate enzyme activity.
Rainbow [258]

Answer:

Explanation:

An allosteric enzyme is one in which the activity of the enzyme can be controlled by the biniding of a molecule to the "allosteric site". This really just means somewhere other than the active site. Thus allosteric control of an enzyme can be classed in two ways. A positive allosteric modification is the binding of a molecule to the enzyme which increase the rate of reaction. Sort of like catalysing the catalysing effect of an enzyme. Obviously the opposite is true of negative allosteric modification. A good example for this is the activity of phosphofructokinase, which is promoted by a high AMP concentration, and inhibited by a high ATP concentration. This should make sense if you think about the action of a kinase etc.
