Complete question:
Question: Genes in different chromosomes _____ during meiosis. Genes that are very close together in the same chromosome are _____.
a) do not assort independently; unrelated
b) assort independently; unrelated
c) assort independently; linked
d) do not assort independently; linked
Answer:
c) assort independently; linked
Explanation:
During anaphase-I of meiotic division, homologous chromosomes are moved to the opposite poles of the cell. This segregation also separates the alleles of genes present on the chromosomes to the opposite poles. The segregation of genes is a random event which means that the alleles of one gene segregate independently of the alleles of some other gene. This requires that the genes are present on separate chromosomes.
The genes present close together on the same chromosomes are linked. This means that they are inherited together and do not exhibit independent assortment.
The similarity of 94% in their DNA sequence suggest that they have originated from a common ancestor and are closely related species.
Explanation:
The difference in DNA sequences in different species is due to the accumulation of genetic variation in the course of natural selection and evolution. Less is the difference in DNA sequences of two organisms the more related they are.
Genes determine the characteristics in an organism, and they are DNA sequences determining the protein to be formed. The similarity in DNA sequence of two species establish the evolutionary relationship among them.
Due to the genetic variation in species, the natural selection of the species had caused the evolution of the species adapted well to the environment.
<span>The correct answer is true. Sustainability can be achieved through careful resource management. By managing the resources and making proper use without wasting them ensures sustainability. The concept of sustainability demands careful and responsible people working towards a common goal of resources management.</span>
Answer:
Half-life is that the quantity of your time occupied for half the preliminary material to fragment. Therefore the nuclide with smaller half-life fragments over the nuclide with the lengthier half-life. Therefore nuclide A fragments a lot of manufacturing extra beta emissions than nuclide B. therefore nuclide A harvests the larger emission experience.
Answer:
an object at <u>rest</u> stays at <u>rest</u> or an object that is <u>moving</u> at a <u>velocity</u> in a straight <u>line</u> keeps moving at that <u>velocity</u> unless another <u>force</u> acts on it
