Answer:
The correct answer is: c) usually produces offspring that cannot reproduce.
Explanation:
Hybridization, also knowns as selective breeding, is an <u>artificial process</u><u> that involves selecting parents with specific characteristics in order to obtain an offspring with the same traits</u>.
Hybridization is very common and has been performed by humans for thousands of years: from selective breeding crop plants, to do so with dogs in order to create more desirable breeds.
Option A is incorrect because hybridation does not occur in nature, it is an artificial process.
Option B is incorrect because hybridation often happens when the selected parents are chosen to reproduce (by a human).
Option D is correct because an important amount of hybrids are sterile (for example: mules).
Option D is incorrect as well because the offspring is not identical: it shares a combination of genes from both parents.

Hi, i got this answer in my class cause we actually did the same thing.
Answer:
Proteins in a protein complex are linked by non - covalent protein - protein interactions. The process of complex formation comprises of steps namely : An encounter complex is formed that either proceeds towards final complex or dissociates again.

Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
