A come,a seats 250 people. If 170 people are in the cinema, what percentage of the seats are filled?

Answers

Answer 1
Answer:

Given that there are 250 seats in the cinema and they are 170 people sitting on the seats provided, in order to get the percentage we will first arrange the given details.

250 seats

170 seats filled

X = percentage

Take 170 / 250

So it will be 170 ● 100 = 17,000

Next, 17,000  250 = 68

So we will have 170 is the 68% of 250. Therefore, 68% of the seats in cinema are filled.

In Africa savanna more wildebeest are born than the environment can support. Which is most likely to happen over a period of years as a result

Answers

Answer;

Individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce.

Explanation;

-In Africa savanna more wildebeest are born than the environment can support. As a result over a period of years individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce. This is referred to as natural selection.

-Natural selection is the process where organisms with favorable traits are more likely to reproduce. In doing so, they pass on these traits to the next generation. Over time this process allows organisms to adapt to their environment.

As a result of having more wildbeest than the environment can support, over a period of years to come, it is only the ones that are able to adapt to the situation that will survive and give birth to young ones while those that are unable to adapt to the situation will die out. This phenomenon is called the survival of the fittest. Because there were more wildebeest than the food resources that are available, there will be competition and only those who can cope will survive and reproduce while others die out.

In an unfortunate accident, a young man is struck in the leg by a bullet that tears through an artery just above his right knee. The subsequent blood loss leads to a rapid drop in blood pressure. Receptors in the aorta monitor blood pressure and send signals to the vasomotor center of the brain. In this case, the vasomotor center will increase its stimulation of smooth muscle in the blood vessels, which will cause them to constrict. This constriction leads to an increase in blood pressure. What represents the effector in this feedback system?

A) blood vessel diameter
B) receptors in the aorta
C) vasomotor center
D) blood pressure

Answers

Answer:

Answer is D. Blood pressure.

Explanation:

Blood pressure is the pressure of the blood within the arteries, produced by the contraction of the heart muscle.
