Answer:

(B) the mouth

Explanation:

"Light penetration in a river or stream is likely to be lowest at the mouth of the river".

This is because in the beginning, the river is basically free of particulate matter and is also clear and so there is an ample amount of light penetration in the beginning.

At the middle portion, the suspended thing is high, but due to the speed of the water, the particles get cleared.

However, at the mouth of the river, there is a large concentration of particulate matter, and thus light penetration is the lowest.

Hence, option B is correct.

MAVERICK [17]

Answer:

The correct answer is option d, that is, endocytosis.

Explanation:

A procedure in which a component gains entry within the cell without getting passed through the cell membrane is termed as endocytosis. In this process, the cell captivates the substances from the external of the cell by engulfing and combining them with its plasma membrane.  

The process is further differentiated into three distinct kinds. These are phagocytosis, pinocytosis, and receptor-mediated endocytosis.

Use the information below to answer the following question(s). In a survey, the rate of heavy smokers was reported as 270 per 10
Eddi Din [679]

The probability that neither of them is a heavy smoker is 0.53 or 53%

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.

In this case:

Probability that selected one is heavy smoker is:

p=270/1000=0.27

Number of individuals selected  is 2 and We know that:

P(X=x)=nc_x(1-p)^{n-x}(p)^x

We need to prove that X=0:

P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0

P=0.5329
