Communicable disease or also known as infectious disease is the spread of disease from one person to another in a variety of ways: through air, contact with bodily fluids, discharges or blood, direct contact, and bites. Through the years, medical science had created lots of ways to control and prevent the spread of such diseases. One of these is the development of Immunization. Immunization works by preparing the body to fight foreign microorganisms that may harm the body. This boosts the body's natural defense against bacteria and virus by allowing the body to release more antibodies. This would enable to body to recognize the possible virus or bacteria that might invade inside the system.

Answer:

Communicable disease or also referred to as communicable disease is that the spread of disease from one person to a different in an exceedingly kind of ways: through air, contact with bodily fluids, discharges or blood, direct contact, and bites. Through the years, bioscience had created plenty of ways to manage and forestall the spread of such diseases. one in all these is that the development of Immunization. Immunization works by preparing the body to fight foreign microorganisms that will harm the body. This boosts the body's natural defense against bacteria and virus by allowing the body to release more antibodies. this might enable to body to acknowledge the possible virus or bacteria which may invade inside the system.

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.

Which of the following is a correct statement about sugar movemetn in phloem?
Simora [160]

Answer:

a. movement can occur both upward and downward in the plant

Explanation:

The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.

Explain why the size of a new moon would affect the appearance of a solar eclipse.
USPshnik [31]

A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.
