The correct answer is option A- HIV virus.

HIV virus is an example of enveloped virus, that has the ability to infect a host cell by attaching itself to it and fusing with the host cell. Once infected, the virus leaves the host cell and moves to another cells to infect them. The HIV virus contains glycoprotein spikes to attach to the host cell.

Q. A person’s blood glucose level fluctuates during the day, asrepresented in Figure 1. Two hormones, insulin and glucagon,are di
Minchanka [31]

Answer:

If the person has another meal after 5 pm, the glucose level in the blood will increase, and the insulin level too.

Several hours after the meal, the glucose levels will decrease, and the glucagon levels will increase.

Explanation:

When a person ingests another meal after 5 p.m, the glucose levels in the blood will increase, as the body does not need all that glucose right now the insulin levels in the blood will increase to store glucose for later. The glucagon levels after a meal are very low because the aim is to store glucose not use it.

Several hours after the meal, the body needs the energy to keep operating so it will use the glucose that was stored, to do this, the levels of glucagon in blood have to increase and release the glucose, and the levels of insulin in blood have to decrease.

what types of minerals are good conductors of electricity, are strong and can be formed into various shaped and sized products w
Sidana [21]

Minerals which are good conductors of electricity are described below.

Explanation:

  • metals tend to be highly efficient conductors of heat and electricity. The vast majority of elements on the periodic table are metals, and most of these fall into one of five families: alkali metals; alkaline earth metals; the very large transition metals family; and the inner transition metal families, known as the lanthanides and actinides.
  • Metals are lustrous or shiny in appearance, and malleable or ductile, meaning that they can be molded into different shapes without breaking. Despite their ductility, metals are extremely durable and have high melting and boiling points. They are excellent conductors of heat and electricity, and tend to form positive ions by losing electrons.

The function of the liver in humans is to maintain the [glucose] circulating in the blood stream at reasonably constant levels.
Archy [21]

Answer:

Due to difference in function.

Explanation:

Glucokinase in liver behave differently than the hexokinase in other cells because glucokinase performs different function in the body. Glucokinase is an enzyme that is responsible for sensing the glucose level in the blood and also plays a key role in the storing of glucose as glycogen while on the other hand, this storing ability is absent in hexokinase so that's why the glucokinase in liver behave differently than the hexokinase in other cells.
