Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.

An increase in heart rate will most likely result in
O (1) a decrease in metabolic rate
O (2) an increase in pulse rate
O (3) an increase in cell division
O (4) a decrease in body temperature

Answers

Answer:

O (2) an increase in pulse rate

An increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).

What is Heart?

Heart is a fist shaped organ which pumps blood throughout your body present in the centre of the chest tilted slightly towards the left. It is the primary organ of the circulatory system which pump blood around the body as the heart beats. The blood sends oxygen and nutrients to all parts of the body and carries away unwanted carbon dioxide and waste products from there.

Heart has four chambers (lobes) made up of muscles- two on the left side and two on the right made up of three layers of tissue -epicardium, myocardium and endocardium. These layers are surrounded by the pericardium which a thin outer lining protecting the heart.

It circulates abut 5-8 liters of blood. Heart, blood and blood vessels together make the cardiovascular system. Blood is pumped around your body through a network of blood vessels- Arteries, Capillaries and veins. Heart has four valves which act like gates which keep the blood moving in the right direction.

Thus, an increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).

it may affect the animals and other tree's.

Explanation:

it may affect animals because since it is a new tree, you might not know that it may be harmful for some animals, like maybe the berries the produce are poisonous or fruits some animals are forbidden to eat. this may be a problem because some animals may accidentally eat that fruit and possibly be injured or die.

trees need sunlight and food, if another tree hopes in suddenly there would be more competition for sunlight and water, there may also be not enough water and sunlight for all the trees to share. this is a problem because if the trees can't get enough sunlight and water, they would die and this leads to a broken home for the animals living in that tree.

Speckled trout and red drum both prey on mullet along the Texas coastline. Dead zones are caused by excessive nutrient pollution, along with other factors that deplete the oxygen from the water. What likely effect would increasing dead zones have on the populations of speckled trout, red drum, and mullet?

Answers

Answer:

All Three Populations Would Decrease

Explanation:

Dead zones have little to no life in them, and besides the fact that this would mean the popoulations of all of them would just be down because of this, mullet will die out due to nothing to feed on, which will make drums and trout also die out, so all of the populations would go down.

The effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.

What do you mean by Prey?

Prey may be defined as an animal that is hunted and killed by another for food.

Dead zones lead to a decline in biodiversity of that area, due to the excessive nutrient pollution and depletion of oxygen. If the members of mullet species get reduced in an environment, species of speckled trout and red drum feel the shortage of food, and hence they also get eliminated or die from the surrounding.

Therefore, the effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.

Why is genetic variation among individuals beneficial?(1 point)

A) More genetic variation means higher rate of survival versus species that have less genetic variation.

B) Genetic variation staves off extinction because it creates a fit population.

C) Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.

D) Genetic variation leads to more new traits in the population which means evolution can occur faster.

Answers

Answer:

Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.

Explanation:
