Animals takes in this oxygen and release it as (blank)?

Answers

Animals take in this oxygen and release it as carbon dioxide. It is the process of respiration that helps the animals to survive. Actually the oxygen is transferred to the blood and the cells and then the carbon oxide is transferred from the blood and cells to the lungs for breathing out. Carbon dioxide is a waste material for our body. The build up of carbon dioxide in the body can be very fatal and lead to death of the animal. It is actually the reverse in case of plants. Plants take in carbon dioxide for making food by the process of photosynthesis and gives out oxygen. So it is a balancing act between animals and plants.
Animals release it as Carbon Dioxide

What happens during transcription?a. The transcription process stops.
b. RNA polymerase is guided to the correct place.
c. mRNA is produced from the DNA.
d. DNA is produced from the mRNA.

Answers

c. mRNA is produced from DNA

Transcription happens before translation. :)

Final answer:

During transcription, mRNA is produced from the DNA. It involves the enzyme RNA polymerase and requires specific protein factors and DNA promoters.

Explanation:

During transcription, mRNA is produced from the DNA. It is the first step in gene expression and takes place in the cell nucleus. The enzyme RNA polymerase is responsible for transcribing the DNA sequence into an RNA molecule, which will later be used to produce proteins. It requires specific protein factors to initiate the process and DNA sequences called promoters to guide the RNA polymerase to the correct place.

An eagle is a carnivore. It MOST LIKELY gets the energy it needs to reproduce fromA) oxygen.
Eliminate
B) plants.
C) the sun.
D) rodents.

Answers

Answer:

The correct answer is option D, rodents

Explanation:

Eagle is carnivore thus it feed on flesh of other animals. Thus among all the given options flesh can be obtained from rodents only. However the common diet of eagle includes mammal of sizes varying from small to medium. Mammals like squirrels, raccoons and rabbits are among the common diet of eagle. However,  some eagle also feed on bird and fishes.  

.

The correct answer is D. This is because if something is a carnivore it consumes meat. Rodents are made of meat.

The function of glycogen phosphorylase is: question options: a. the conversion of glucose-1-phosphate to glucose-6-phosphate.
b. inhibit the production of glucose-1-phosphate.
c. to breakdown atp.
d. stimulate the buildup of glycogen.
e. catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules.

Answers

Answer:
             The correct option is e (catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules).

Reason:
              It is that type of enzyme which is responsible for the conversion of glycogen into glucose through a series of reactions. First of all glycogen is converted to glucose 1-phosphate catalysed by glycogen phosphorylase. It is then converted into glucose 6-phosphate with the help of phosphoglucomutase. In liver it is then converted into glucose which enter into blood stream.
I hope it will help you. If not then look at diagram you will easily understand the phenomenon. 

Final answer:

Glycogen phosphorylase catalyzes the phosphorolysis of glucose-1-phosphate from glycogen molecules, playing a critical role in the process of glycogenolysis. It helps in the conversion of stored glycogen into glucose for use as energy by the body.

Explanation:

The function of glycogen phosphorylase is to catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules. What this means is that it helps to break down glycogen, a form of energy storage in animals, into glucose-1-phosphate. In other words, glycogen phosphorylase plays a critical role in the process of glycogenolysis, which is the process of converting stored glycogen into glucose for use as energy by the body. It does this by adding a phosphate group to the glycogen molecule, creating glucose-1-phosphate, which can then be converted into glucose-6-phosphate and ultimately used to generate ATP, the cell's primary energy currency.

20. Neutrons and
are found in the nucleus of an atom. (1 point)

Answers

You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together.

Gene is investigating what makes bread moldy. He put two identical slices of bread on separate plates. He made one slice moist and kept the other slice dry. He left the uncovered plates on a table for 2 hours. Then, he sealed them in plastic bags and put them in a dark, warm place. He looked at them each day for five days. After five days, he observed that 50 percent of the moist slice was moldy, and none of the dry slice was moldy. If Gene observed the slices for three more days, what would he most likely observe?
