if a mutation occurs in the somatic tissue, approximately how many of the gametes will carry the mutation?
Mrac [35]

None: Only those mutations that occur in the germ line and result in gametes will have a chance of being passed on to progeny. An alteration in DNA that occurs after conception.

Somatic mutations can occur in any of the body's cells except germ cells (sperm and egg) and are therefore not passed on to children. These alterations can (but not always) cause cancer or other diseases. Mutations in somatic cells are called somatic mutations. Because they do not occur in the cells that give rise to gametes, the mutation is not transmitted to the next generation sexually. Human somatic cells have 46 chromosomes: 22 pairs and 2 sex chromosomes that may or may not form a pair. This is the 2n or diploid condition. Human gametes have 23 chromosomes, each of 23 unique chromosomes, one of which is a sex chromosome. Somatic cells are the cells in the body other than sperm and eggs (called germ cells). In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one inherited from each parent. Mutations in a somatic cell occur in somatic cells and are transmitted by mitosis, resulting in cancer. However, mutations in a gamete are passed on by meiosis, resulting in mutated offspring. A genetic mutation occurs during DNA replication, and chromosomal mutations occur during meiosis.

The qrs complex is associated with ________. the qrs complex is associated with ________. depolarization of the ventricular sept
Zepler [3.9K]

In a typical ECG (Electrocardiogram) the first wave obtained is P wave; The P wave represents the depolarization of the atria. After this, the QRS complex is formed. The QRS wave represents the depolarization of the ventricles.  During the depolarization phase, the ventricles contracts and pushes the blood into the atria. Hence, the correct answer is depolarization of the ventricles.

What is digestion and how does it work
slamgirl [31]

Answer:

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Explanation:

Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.
