The process during meiosis that contributes to the gamete having a material that is unique is the anaphase. This step splits the chromosomes into two separate chromatids. The resulting gametes contain 50% of the chromosomes and this 50% is not the same for the other gametes.
physical and chemical barriers that form the first line of innate defense include the acidity of the stomach, tear fluid from the eye, an un-punctured skin and mucus and cilia of the respiratory tract.
Food is digested by the stomach, a J-shaped organ. It generates acids and enzymes. Food is broken down by this concoction of digestive juices and enzymes so that it may move on to your small intestine. The digestive system includes your stomach. Humans and many other animals, including numerous invertebrates, have a muscular, hollow organ called the stomach in their gastrointestinal tracts. The stomach is a crucial organ in the digestive system and has a dilated configuration.
In animals, the respiratory system is divided into the respiratory tract, which is engaged in the respiration process. The respiratory epithelium and respiratory mucosa line the respiratory tract. There are upper and lower airways in the respiratory tract.

Answer:
The ATP molecule shown consists of a base,<em> Adenine</em>, and a chain of three phosphates.
Explanation:
ATP can be described as a molecule which is the main energy source for cells of an organisms body. ATP is made up of a nucleotide base which is adenine and three phosphates attached to it hence the name adenine triphosphate.
The energy is released from an ATP molecule by breaking or hydrolyzing it. This process releases adenine diphosphate, a phosphate molecule along with loads of energy. ATP is the main molecule which cells use to carry out their normal functions.
Answer:
The correct answer choice is C.) 2 identical, diploid daughter cells.
Answer:
Reverse mutations in the colonies enabled to recover the ability to synthesize histidine. The 2-aminoanthracene is a chemical agent that induce mutations and therefore it is potentially a carcinogen.
Explanation:
A reverse (suppressing) mutation is a type of mutation capable of restoring the activity of previously mutated genes. On the other hand, 2-aminoanthracene is an aromatic amine carcinogen capable of inducing hepatic and skin tumors. In this case, 2-aminoanthracene has been used to induce reverse mutations at <em>loci</em> responsible for the synthesis of histidine.
