Answer:
in sexual reproduction we get genes from both our parents and we have a combination of them...that leads to genetic diversity...more diversity means more chances to survive different environment conditions.... in asexual reproduction.. offsprings are identical.if environment conditions are rough...all of them won't stand a chance...and also....in sexual reproduction genetic variation can lead to evolutionary advancements
Answer:
C2
The atlas is the first cervical vertebra (C1) and bridges the occiput with the axis, the second cervical vertebra (C2), and the rest of the cervical spine.
Because it ........................., the brain's HYPOTHALAMUS ultimately controls the endocrine system.
The hypothalamus is the part of the brain that controls the endocrine system, it does this by linking up the nervous and the endocrine system via the pituitary gland. Hypothalamus functions by releasing hormones which either inhibit or stimulate production of hormones in the anterior pituitray gland.
Answer:
The universality of genetic code.
Explanation:
The DNA is a molecule made up from 4 different nucleotides (A, T, C or G). The sequence in which these nucleotides are ordered constitute a code that gives a cell instructions to produce a specific protein. This is called the genetic code.
Every three nucleotides code for a specific amino acid. For example, ACG codes for Arginine, CUC codes for Proline, and so on.
The genetic code is universal. This means that in all living organisms, a particular sequence of three nucleotides will code for the same amino acid. This property guarantees that the human gene that codes for human insulin will also code for human insulin in bacteria.
Darwin illustrated that natural selection sorts between the hereditary variations, for example, the weight of an organism, its height, and color of the coat and so on. The most current discussions of heredity focus on heredity traits like those that can be shown to be passed on genetically.
The discussions of heredity show confusions between the process accountable for the individual development and the processes accountable for the conduction of traits from one generation to the next.
The Darwin's understanding of heritability debilitated his arguments as he was not 100 % sure on what he actually is discussing about. However, if he could argue the truth and demonstrated them with facts, then it would be rational.
