Answer:
Skin cancer refers to the abnormal activity of skin cells associated with carcinogenesis
Explanation:
This disease is associated with the DNA damage (mutations) often caused by the irrational exposition to UV sun rays that trigger DNA mutations capable of both inactivating tumor suppresor genes and activating oncogenes
Hi there!
For all organisms to survive, they start off with sunlight. That's the main and immediate source of energy to any organism(s).
Sunlight gives warmth and energy and light of course.
Hope this helps!
Answer:
Land can become polluted by household garbage and by industrial waste. In 2014, Americans produced about 258 million tons of solid waste, according to the U.S. Environmental Protection Agency. A little over half of the waste — 136 million tons— was gathered in landfills. Only about 34% was recycled or composted.
Hope this helps and I hope its correct.
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.

Reducing sugar is any sugar (all monosaccharides, some disaccharides, oligosaccharides, and polysaccharides) that is capable of acting as a reducing agent because it contains free aldehyde group or free ketone group.
Aldehyde group or alkanal is an organic compound containing formyl group. The formyl group is a functional group consisting of a carbonyl center bonded to hydrogen and an R group. This group can be readily reduced to primary alcohol with the help of catalyctic hydrogenation either applied directly or by transfer hydrogenation.
Ketone group unlike aldehyde group does not have a hydrogen atome bonded to the carbonyl group but it can still be hydrogenated.
