Answer:
a prezygotic barrier
Explanation:
Both wild tigers and lions are said to be reproductively isolated.
Reproductive isolation is defined as the existence of barrier between organisms of different species such that they cannot reproduce.
The mechanisms of reproductive isolation varies. While some act to prevent the formation of zygotes (in case of mating) between organisms of different species, some ensures that the resulting zygotes are invalid.
Reproductive isolation mechanisms that act to prevent fertilization and formation of zygotes are referred to as prezygotic mechanisms while those that ensure that invalid zygotes result (in case of successful fertilization) are referred to post zygotic mechanisms.
<em>The natural differences in the ranges of wild tigers and lions ensure that both animals do not mate with each other, let alone results in zygote. This is a form of pre-zygotic reproductive isolation mechanism.</em>
d. scientific theory
Explanation:
The statement that all living things like planktons are made up of cells is a true scientific theory.
All living organisms are made up of cells and all cells are derived from pre-existing cells is the first and most fundamental postulate of the cell theory.
- the concept that living things are made up of cell is from the cell theory.
- the cell is the fundamental unit of life.
- the cell theory provides an explanation into cells as the unit of life

The symptoms of a lung-expansion injury tend to appear immediately after the dive while the symptoms of decompression sickness tend to appear usually slower after the dive.
Why does oxygen treat scuba-related illnesses?
Decompression sickness (DCS) patients address the disease process by dissolving air bubbles in the blood and tissues and diffusing excess nitrogen to oxygenate ischemic regions.
Needs to be recompressed Recompression was traditionally carried out with the assistance of a personal doctor or technician and a customized chamber that allowed for a controlled rise in atmospheric pressure. DCS divers have to travel further to decompression rooms since the number of rooms accessible for 24-hour emergency care countrywide is decreasing at an alarming rate.

In the case of left-sided heart failure, blood backs up into the lung circuit. You would expect Mr. Kalani to have pulmonary direct result of this edema.
<h3>The effects of Left-sided heart failure</h3>
Left-sided heart failure occurs when the heart becomes unable to pump blood to the whole body. This is because the heart can not handle the blood that is coming from the lungs.
When left-sided heart failure occurs, fluid leaks from the affected capillaries into the nearby tissues of the lungs circuit leading to pulmonary edema.
Excess fluid in the tissues is called edema and in the case of a left-sided heart failure, other parts of the body such as the feet, legs and ankle are equally swollen.

ATP, which is a storage molecule that stands for adenosine triphosphate. The body requires ATP in order to be able to perform basic functions. ATP is found in the mitochondria of cells.
