Answer:
It is an increase in available food amount.
Explanation:
An increase in predators would result in the prey species dying off. A decrease in habitat size would result in the species not having a place to live or hide from predators. A decrease in amount of available water would make the species die of dehydration.

Answer:
<u>Digestion</u> is a process by which large ingested molecules are mechanically and chemically broken down to produce basic nutrients that can be absorbed across the wall of the GI tract.
Explanation:
Digestion is the process by which large molecules of food are broken down into molecules small enough to be absorbed by the body's cells, that is, through this process the body obtains nutrients from food to function properly. The organs that perform this function are part of the digestive system. Digestion and absorption takes place in the gastrointestinal tract (GI track), during its passage through this tube, food remains 3 to 5 hours in the stomach, 4 hours in its movement along the small intestine and 6 to 20 hours in the large intestine .
Answer: Option A.
first degree heart block
Explanation:
First degree atrioventricular block is a condition that is associated with electrical condition system of the heart in which the electrical impulses is conducted from the cardiac atria to the ventricles via atrioventricular node in a slow manner compare to the normal transmission.
It is first degree great block because it is characterized by prolong PR interval on an electrocardiogram (ECG) to more than 200 msec and atrial impulse is transfered to the ventricles, which lead to regular ventricular rate.
The PR interval of the surface ECG is measured from the start of atrial depolarization (P wave) to the commensement of ventricular depolarization or QRS complex.
Answer: Nuclear power
Explanation: No greenhouse gases are produced in the fission process, and only very small amounts are produced across the whole nuclear life- cycle. Nuclear power is an environmentally-friendly form of electricity generation and does not contribute to air pollution
