Answer:
The correct answer is: A. Only the best-adapted animals in a population survive.
Explanation:
- Natural Selection is the process by which the individuals of a species which has the potential to sustain and survive in adverse or changing environment gets a survival advantage over those individuals which are unable to adapt themselves to altered environmental conditions.
- As the less potent individuals die in altered environmental conditions the adaptable individuals escapes competition with them for natural resources.
- Evolution causes species to alter their characteristics depending upon the demand of the conditions. These changes can vary, can be less or drastic.
- Animals pass all the newly adapted traits to the successive generations either as genetic traits or as acquired traits, as this is necessary for the offspring to survive in the altered environment.
- Natural selection is best defined as "the survival of the fittest".
Yes, the human body is composed of approximately 60% of water. The given statement is true.
Water is essential for human health and for the survival of life on earth.
It keeps them alive, stale and healthy by providing oxygen and chief nutrients to the body.
It lubricates joints, knees and also removes waste materials from the kidney, and keeps them clean.
In adult humans, there is approximately 60% of water in their bodies.
The concentration of water is more in lean tissues than in fat tissues.
Women's bodies have more fats than men and water makes up only 55% of their bodies.

Answer:
- flippases translocate lipids from outer (extracellular) leaflet to inner (cytosolic) leaflet,
- floppases, move phospholipids from inner (cytoplasmic) leaflet to outer (extracellular) leaflet, ABC transporter, move phospolipids across the lipid bilayer down the concentration gradient
- scramblases Not ATP-dependent, Activation may result in increased membrane lipid symmetry, translocate phosphatidylserine, preventing apoptosis and engulfment by macrophages,
Explanation:
Flipases are transportes that require energy for their functioning (ATP dependent) beause they move phospolipids across the lipid bilayer against the concentration gradient (from extracellular side to cytosolic side).
Floppases are ABC transporters, opposite than flippases (move phospholipids from the cytosolic side).
Scrablases are bidirectional transporters, responsible for asymmetry formation. It also enables exposure of phosphatidylserineon the outer leaflet when it is necessary.
Species is defined as a group of organisms that consist of similar individuals capable of interbreeding or exchanging genes among themselves.
