Answer:
exposure to ultraviolet radiation is a correct answer.
Explanation:
Ultraviolet light exposure results in the formation of pyrimidine dimers. Ultraviolet radiation damage the DNA by resulting in chemical changes.
Ultraviolet radiation is absorbed by the pyrimidine bases( cytosine and thymine in DNA) and result in the formation of covalent bonds between the succeeding bases.
The formation of the pyrimidine dimers results in the distortions of DNA helix and disrupt the base-pairing during the replication of DNA which results in a mutation.
A gamete is randomly getting a copy of a chromosome from its mother and father. This means that gamete will get #1 from the mother and the next chromosome will be a pure chance of getting chromosome #2 from mother or father.
Explanation:
- Meiosis is the process that separates the two chromosomes and giving one copy of each to the gamete. This is the reason why egg and sperm together are forming zygote which is diploid.
- The main advantage of sexual reproduction is that each clone is different. Each and every egg is different from each other. This is the same in the case of sperm too.
- At the end of meiosis, males will have 1 cell with 4 sperms all are different in nature, but in females, it will one egg because, during cell division, one cell will hog the cytoplasm.
Sterol and stanol esters, also go by the name - phytosterols and help lower blood cholesterol level or LDL cholesterol. LDL is also called bad cholesterol.
The correct answer is class.
Taxonomic category (rank) is the level of a group of organisms in a taxonomic hierarchy. The major ranks are domain, kingdom, phylum, class, order, family, genus, and species. Higher rank has more general characteristics of organisms. The lowest rank-species contains most specific descriptions of life forms in it.
