The correct answer is option C

Animals get nitrogen from the plants and animals they eat. The plants take nitrogen from the soil by the help of nitrogen fixing bacteria and then these plants are eaten by the animals and they get nitrogen in this way.

The carnivores animals feed on small animals that contain nitrogen.When they die the nitrogen gets back into the soil to be used again by the plants.

In this way the animals get nitrogen by eating the plants and animals present in the environment.

5 goals of psychology?

Svetllana [295]

1. Describe - the first goal is to observe behavior and describe.
2. Explain - While descriptions come from observable data, psychologists must go beyond what is obvious and explain their observations. In other words, why did the subject do what he or she did?
3. Predict - Once we know what happens, and why it happens, we can begin to speculate what will happen in the future.
4. Control - Once we know what happens, why it happens and what is likely to happen in the future, we can excerpt control over it
5. Improve - Not only do psychologists attempt to control behavior, they want to do so in a positive manner, they want to improve a person’s life, not make it worse.

The Griffith experiment showed that certain strains of Streptococcus bacteria could transform from one strain to another when co

AnnZ [28]

Answer:

The options

A. It suggested that DNA is the

"transforming principle."

B. It confirmed that DNA is a double helix composed of two antiparallel strands.

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.

D. It proved that DNA is

semiconservative replication.

The CORRECT ANSWER IS A.

A. It suggested that DNA is the

"transforming principle."

Explanation:

A. It suggested that DNA is the

"transforming principle."✔

Griffith's experiments proved

that transformation can be seen in

pneumococcus, but gave no proof based on what molecular background the transformation was

WHILE, the Avery MacLeod-McCarty experiments proved that DNA was THE TRANSFORMING PRINCIPLE.

B. It confirmed that DNA is a double helix composed of two antiparallel strands.❌

These findings were established by James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.❌

The findings was established by Erwin Chargaff.

D. It proved that DNA is semiconservative replication.❌

The findings was established by Matt Meselson and Franklin Stahl.

The output region is the site of ______________________.

tester [92]

Answer:

The correct answer is option C (voltage gated Na+ channels).

Explanation:

Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.

The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.

At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.

Thus, option C (voltage-gated Na+ channels) is the correct answer.

Adrenaline stimulates glycogen breakdown in skeletal muscle cells by ultimately activating glycogen phosphorylase, the enzyme th

r-ruslan [8.4K]

Answer:

d) A constitutively active mutant form of PKA in skeletal muscle cells would lead to an excess in the amount of glycogen available.

Explanation:

This occurs in the process of Glycogenolysis. The process involves breaking down of glycogen to glucose -1- phosphate and glycogen which helps in the release of glucose into the blood stream to prevent hypoglycemia(low blood sugar). The glucose-1-phosphate is later converted to glucose -6-phosphate. The latter enters the glycolytic pathway in which the reaction is catalysed by the enzyme phosphoglucomutase.

This homeostatic glucose regulation is regulated by the protein kinase(PKA)/ cAMP pathway in the skeletal muscles, the liver and the pancreas.
