ATP and ADP both play a role in cellular reactions involving energy. How are these two molecules related

Answers

Explanation:

If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. ... When it's run down, it's ADP.

ATP is converted into ADP and ADP can be changed back to ATP by the addition of a phosphate group.

The function of a virus?

the function of a bacteria?

Answers

Answer:

the function of a virus is to deliver its genome into the host cell to allow its expression by the host cell. It will, at least attempt to, take over the body and infect the body with the disease virus on it.

the function of a bacteria can be good or bad. for good purposes for example, would be the digestive bacteria that breaks down the food and uses the energy to give the body energy. the bad version of bacteria is to spread from surface to surface, like the flu for example.

Explanation:

A flu virus can remain infectious on surfaces such as desk and doorknobs for long periods of time how does the ability of the flu virus to remain infectious on surfaces lead to high rates of the flu illness

Answers

Answer:

Explanation:

For question 3 the answer is DNA contains genetic material!!

Hershey and Chase used radioactive isotopes to label a bacteriophage. ... After allowing the bacteriophage to infect the bacteria, the presence of radioactive phosphorus in the bacteria confirmed that DNA was the genetic material found in genes!!

For question number 4 the answer is X-ray diffraction!!

X-ray crystallography

Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.

what will happen to us if our body temperature fluctuate​

Answers

Answer:

If the body temperature is too low, the enzymes in the body become inactive so many metabolic reactions cannot happen effectively, our metabolic rate will be affected, we may suffer from hypothermia.

If the temperature is higher than 37degree celsius, we will have a fever. But this actually allows enzymes to work at their optimum temperature, which speeds up the metabolic reactions in the body and is good for us.

D)Infrared waves are used to transmit information from
remote controls.

Answers

Answer:

C) Radio waves are used to transmit television and radio  programs.

Explanation:

Radio wave is a form of electromagnetic radiation which is used in communication technologies, such as radio, television, and mobile phones. Communication technologies or devices receive radio waves and then they are converted into mechanical vibrations in the speaker that creates sound waves.

Hence, the correct answer is "C) Radio waves are used to transmit television and radio  programs."

What factors might affect the availability of fish to eat for the egret and stork
populations?

Answers

Answer:

Factors such as pollution, the depth at which both birds go down to catch the fish (if you look at experiments populations of fish tend to deplete quicker when in a shallow depth than a deeper depth), another factor would be the use of mammals fishing for food- this factor can range from a bear all the way down to humans taking huge quantities of fish in from the sea.

These are only a few factors I could genuinely think of.

HELP ASAPPP Why can insertions and deletions affect more than just the codon(s) that they directly change? Hint: Why are they called frame-shift mutations?

Answers

Answer:

Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions, and deletions are usually more harmful than a substitution in which only a single amino acid is altered.

Explanation:

What part of the rotifer is responsible for crushing food?
I said foot but I might be wrong. Help, anyone?

Answers

Answer:

Rotifers are specialists at living in habitats where water dries up regularly.

The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]

The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]

Explanation:

The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.

Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.

Answer:

Trophi (got it right on my quiz)

Explanation:

The trophi located behind the rotifer's mouth are responsible for crushing food.

How many membranes cover the Golgi apparatus?

Answers

Answer:

The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.

Explanation:

The Golgi apparatus is a series of membranes shaped like pancakes. The single membrane is similar to the cell membrane in that it has two layers. The membrane surrounds an area of fluid where the complex molecules (proteins, sugars, enzymes) are stored and changed.

Answer:

3 to 8 membranes called cisternae
