Which example represents a DISADVANTAGE of asexual reproduction? A) Genetic variety slowly causes hundreds of species of beetles to form from a single species. B) A single antibiotic is able to quickly and easily kill millions of genetically identical bacteria. C) Millions of bacteria are quickly produced by cell division, in one afternoon in a jug of milk that has been left on the counter. Eliminate D) Male anglerfish must live on larger females as parasitic mates, since they encounter other anglerfish so infrequently in the deep ocean.

Answers

Answer:

The correct answer would be an option B.

Asexual reproduction is a reproduction in which offspring are produced from a single parent.

It does not involve fusion of gametes and crossing over due to which the offspring contain identical genome as that of parents.

This reduces the genetic diversity in a population due to which all the organisms of a population are at equal risk of extinction under unfavorable conditions such as high temperature, antibiotics, change in pH of surrounding medium et cetera.

Thus, the disadvantage of asexual reproduction is the lack of genetic diversity due to which a single antibiotic is able to kill millions of genetically identical bacteria.

When the atmosphere is warmed by the sun the changes in air pressure and air temperature result in:

Answers

Answer: Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure. But, air pressure also affects temperature - the more those molecules bump into each other, the more heat they generate.

What specifically is this biochemical used for, and how is it broken down during digestion?

Answers

digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.During carbohydrate digestion the bonds between glucose molecules are broken by salivary and pancreatic amylase.The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.DNA and RNA are broken down into mononucleotides by the nucleases deoxyribonuclease and ribonuclease (DNase and RNase) that are released by the pancreas.
