Which one of these is involved in adaptive and humoral immunity?

Biology
1 answer:
SpyIntel [72]3 years ago
4 0

Answer:

(d). B-cells.

Explanation:

Adaptive immunity can be described as immunity which develops in response to exposure to a pathogen (or foreign molecule). throughout the life. It is divided into two types, humoral immunity and cell-mediated immunity.

Humoral immunity is mediated by B cells that secrete antibodies against particular antigens. These antibodies recognize and neutralize the antigens and activate cell-mediated immunity, which is mediated by T cells.  

Thus, the correct answer is option (d).

Circuit A has twice the resistance of circuit B. The voltage is the same in each circuit. Which circuit had the higher current
Alchen [17]

Answer:

Explanation:

The higher the Resistance, the lower the current. So if the resistance is 5 and 10 then the 10 ohm resistor has the lower current.

Cells can transport these molecules by packaging them into
Paraphin [41]

Answer:

VESICLES

Explanation:

Molecules of different types are produced in different compartments of a cell. These molecules, however, needs to be transported from one location to another. For this purpose, small spherical structures called VESICLES are used by the cell.

Vesicles are compartments in the cell that functions majorly as transport sacs. They help transport materials and molecules from one organnelle to another within a cell. For example, transport vesicles help in the transportation of matured proteins from the Golgi apparatus to respective locations in the cell.

Attached earlobes are recessive to free earlobes. what is the probability of having a child with attached earlobes when an indiv
erma4kov [3.2K]
I believe that the probability of having an individual with attached earlobes will be 50%. Since the attached earlobes is recessive then its genotype will be (ee), for the unattached ear lobes the genotype will be EE, Ee. Therefore, mating between an individual with attached ear lobes (ee) and one with unattached ear lobes, heterozygous, Ee,  the offspring will be; Ee, Ee, ee, or ee. Therefore; half of the offspring will have unattached ear lones (heterozygous) while another half will have attached ear lobes.

A ball was kicked by a player, the ball was stationary, then it gains a velocity of 5 m/s North. Did the ball accelerate or no?
dimaraw [331]

Answer:

Yes, it accelerates

Explanation:

We have that:

The ball was stationary implies that its initial velocity, u = 0

It gained 5m/s means that its final velocity, v = 5m/s

Using first law of newton, we can determine whether it accelerates or not.

v = u + at

Substitute values for v and u

5 = 0 + at

5 = at

Make a the subject

a= \frac{5}{t}

<em>This implies that the ball accelerates over a period of time t</em>

<em></em>

Another way to tell if it accelerates or not is to consider the change in velocity.

When there is an increment in velocity of an object, the object accelerates.

In this case, the velocity increases from 0 to 5. Hence, we can conclude that it accelerates
