why do polysaccharides like cellulose and peptidoglycan able to resist degradation and enzymatic activity

mixer [17]

Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.

EXPLANATION:

Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
But the polysaccharide like cellulose cannot be absorbed by our body.
Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.
Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes.
Thus, cellulose degradation requires a complex enzyme and cellulose.

This diagram shows the menstrual cycle.

LiRa [457]

Answer:

According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.

Explanation:

The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.

During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.

In the case of a pregnant woman:

Estrogens continue to increase after ovulation, produced by the ovaries and placenta.
Progesterone also increases its levels, as it is a hormone produced by the ovaries and placenta.
Hormone human chorionic gonadotropin (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.

The diagram represents the normal cycle of a woman who is not pregnant.

Two linebackers tackle a quarterback. One hit him with a force of 105 N and the other hit him with a force of 150 N. They are bo

Setler [38]

The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.

Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.

Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.

X has successfully been transmitted to your body; you are now infected. All of the following among A-D are possible consequences

Natasha2012 [34]

The complete options to the question includes:

A.You never show any symptoms of disease and there is no sign of the pathogen in your body.

B.You exhibit mild symptoms of disease and the levels of the pathogen in your body are quickly reduced and eliminated.

C.You succumb to the worst effects of the disease but survive due to administration of antimicrobial agents.

D.You never show any symptoms of disease, but the pathogen persists in your body.

E.There are no exceptions, A-D are all plausible outcomes.

Answer: The correct option is A (You never show any symptoms of disease and there is no sign of the pathogen in your body).

Explanation:

Infectious diseases occurs when an individuals system is invaded by pathogenic microorganisms (virus,bacteria,fungi and parasite). These microorganisms may or may not cause disease but this depends on the healthy state of the host. They can also be transmitted from one person to another.

To explain the options why all are plausible outcomes when X has successfully been transmitted into the body except A includes:

B) option B can occur when the immune system of the host is able to combat X.

C.) Option C can occur when antimicrobial is given to suppress the activities of X

D) option D can occur when the individual may become an asymptomatic carrier of X. ( Individual shows no symptoms and signs of disease caused by X but the pathogen is still present in the body).

But option A is not possible as X must be present to show there was a transmission.
