Answer:
Genetic information is bundled into packages of DNA known as chromosomes.
Explanation:
Chromosomes can be described as thread-like structures made up of genes. A genes can be described as a hereditary molecule which is made up of a segment of DNA. Hence, a chromosome contains genetic information packaged into bundles of DNA.
The number of chromosomes vary for each organism. For example, the number of chromosomes in each somatic cell of the human body is 46. These chromosomes occur in the form of homologous pars.
Answer:
The advantage of inside fertilization is that the fertilized egg is protected against dehydration on land. The embryo is segregated from the woman, limiting young predation. The fertilization of internal eggs by a certain male is also improved.
Explanation:
Interior fertilization is the union in the female body of the egg and the sperm. The female has more control over internal fertilization, as opposed to its counterpart, exterior fertilization. There has to be a technique for males to introduce the sperm into their reproductive system in order for internal fertilization to occur.
Copulation, an intromittent organ, is inserted into the vagina or cloaca in mammals, reptiles, and some other group of species. The cloacal kiss is employed in most birds, and the two animals squeeze their cloacas together as sperm is transferred. Salamanders and Spiders are internally regulated by passing a bundle of sperm from the male to the female. Some insects and certain mollusks are fecundated. The embryos are placed as eggs in the organisms or continue to develop within the mother's reproduction tract as young, viviparous creatures after fertilization.
