Answer:

Glucose is the carbohydrate produced by photosynthesis. Energy-rich glucose is delivered through your blood to each of your cells.while glucose is a usable form of energy.

ATP is the usable form of energy for your cells.ATP is a storable form of energy

Explanation:

The difference between ATP and glucose, is glucose is a storable form of energy, while ATP is a usable form of energy. Thus, option D is correct.

ATP or Adenosine triphosphate principal energy currency of the cell.

It is the byproduct of  photophosphorylation, cellular respiration, and fermentation process. It is highly soluble in water.

Beside energy source, ATP have a role in signal transduction pathways  and DNA synthesis.

Structurally ATP is a nucleotide which made up of adenosine molecule  and three phosphate molecules.

The three phosphate molecules are connected by two phospho-anhydride bonds which releases huge amount of energy upon hydrolysis.

After hydrolysis of ATP is converted into adenosine diphosphate (ADP) energy is released.

In ATP hydrolysis, removal of  one phosphate group releases  7.3 kilocalories per mole, or 30.6 kilojoules per mole.  

Thus, option D is correct.

2.   Pyloric sphincter is the part present between the stomach and small intestine which regulate the flow of food particles from stomach to the intestine. Vagus nerve control the activities of pyloric sphincter. Vagus nerve help the pyloric sphincter to relax.

3.  Efferent nerves of vagus nerve help the gall bladder to contract. Vagus nerve is stimulating the gastric tract to contract. So the vagus nerve stimulation promotpromotprthe production of CCK hormone and it will lead to the contraction and secretion of hormones from the gallbladder. Those contractions will help the gallbladder to empty the hormones from gallbladder.

Answer:

Here is 1 example for some help! :)

Explanation:

Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.

1] Aquatic plants have leaves that float on the surface of water.

2] Thier leaves are rarely have stomata.

3] Thier leaves can perform all the work without xylem.

4] They are usually lack cuticle layer in order to avoid excessive dryness.

Answer:

The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.

Four characters of aquatic plants are as given below:

1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.

2) aquatic plants keep their stomata always open for they do not need to retain water.

3) on each side of their leaves are a number of stomata.

4) aquatic plants have less rigid structure since water pressure supports them.
