At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting from this soil called?

Answers

Answer: They are called Moraines

Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.

Glaciers constantly move on land and they do this under their own weight.

As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.

The resulting hill formed as a result of this soil movement is called a Moraine.

A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.

Fossils can be body parts of ancient organisms, or they can be traces. Give five examples of trace fossils

Answers

Answer:  

Trackways/footprints, mold and cast fossils, feeding marks, coprolites, and burrows. Trace fossils show the activity of ancient organisms rather than the body fossil itself. However, it is rather difficult to identify an organism by use of mere trace fossil, and therefore, it is less accurate.

1. Entry requirements to higher education are the necessary and important criteria that students intending to acquire higher education must attain before they can be granted admission.

2. Four reasons why knowing the entry requirement is important include;

a. It helps the students chose the right courses in high school.

b. It provides a standard for the universities to evaluate students objectively.

c. It ensures the admittance of students to courses suited for their capabilities and strengths.

d. It prepares students for the tasking academic environment by ensuring that they have a background knowledge of their chosen course.

Explanation:

Before students can be granted admission into schools chosen by them, they must meet certain standards to be deemed qualified by the admitting institution. Knowing these standards on time gives the students a sense of purpose and helps them to develop skills and abilities that make them qualified for admission into these schools.

It also helps the university choose the right students for different courses. Studying ahead to have the required certificates for admission helps the student gain background knowledge of their future course.

When a person is suddenly cut by a sharp object, a nervous impulse is sent along a sensory neuron to the spinal cord. The impulse is immediately transmitted through motor neurons to produce a response. Which of the following correctly identifies and describes this response?
A.It is a leamed response that does not occur in infants and small children
B. It is a reflex response that causes various muscles to contract in order to move away from the object.
C.It is a conditioned response that occurs only to prevent injury!
D. It is a voluntary response that is initiated only after the impulse has been caried to the relevant area of the brain.​

Answers

Answer:

B. It is a reflex response that causes various muscles to contract in order to move away from the object.

Explanation:

I just took the Test

It is a reflex response that causes various muscles to contract in order to move away from the object. Therefore, option (B) is correct.

What is reflex response?

A reflex response is an automatic, involuntary response to a stimulus that does not involve the conscious part of the brain. In this case, the reflex response causes various muscles to contract in order to move away from the sharp object, which helps to minimize further injury. Reflexes are a protective mechanism that can operate without the need for conscious control or decision making.

The reflex response described in this scenario is not a learned response, a conditioned response, or a voluntary response. It is an innate, automatic response that occurs in response to a specific stimulus, and it occurs in both infants and adults.

The Go' for the reaction Citrate  Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate  α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?

Answers

Answer:

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Explanation:

ΔG°' for Citrate is +6.64 kJmol-1

ΔG°' for Isocitrate is -267 kJmol-1

ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant

ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

what is the function of valves between the heart chambers

Answers

The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.
Tricuspid valve. This valve is located between the right atrium and the right ventricle.
Pulmonary valve. The pulmonary valve is located between the right ventricle and the pulmonary artery.
Mitral valve. This valve is located between the left atrium and the left ventricle. It has only 2 leaflets.
Aortic valve. The aortic valve is located between the left ventricle and the aorta.
