Answer:
Cells divide by two processes termed as mitosis and meiosis. All the autosomal cells divide by the process of mitosis whereas the sex cells divide by the process of meiosis.
Cytokinesis is one of the most important aspects during cell division as it ensures that both the daughter cells get equal amounts of DNA.
During cytokinesis, the microfilaments which are made up of actin deepen the furrow due to which the cell is able to separate into two new daughter cells.
Answer:
Answer: There is 100% chance that the pea plant will have green pods.
Explanation
Yellow pod color is recessive trait and green pod color is dominant trait. Let the allele for the yellow pod color be 'Y' and for the green pod color be 'y'.
Genotypes of the parents according to the question are-
Yy ( hetrozygous plant) and YY ( homozygous dominant plant)
When these parents are crossed, there is a 100% chance that the pea plant will have green pods. This is because the dominant allele Y is present in all the offsprings. This gives them a green pod color.
Answer:
The process of Desensitization
Explanation:
Subjects are able to perceive a residual image once the green cones in the retina get desensitized. Since every group involved in this study reported having seen a rather intense residual image, we can safely conclude that the green cones did indeed get desensitized.
Answer and Explanation:
Fossils can be formed in a variety of ways. First and foremost, organisms that possess bones (or shells) are the best candidates for fossilization because these structures commonly remain in fossilizing substances such as mud.
The most preserved fossils come from animals that die in aquatic environments or in environments that have a high level of humidity. This occurs because the animal gets buried in a sediment like mud, leading to the decomposition of soft structures and the fossilization of hard structures, such as bones. As layers of sediment are added, the dead body of the organism becomes a fossil.
Also, animals can leave well-preserved fossils during volcanic eruptions when they get trapped in hot ash flows. In addition, this could also occur in tundra ecosystems when animals get trapped in ice, leaving a well-preserved fossil inside. Moreover, plants are also fossilized, this generally takes place in sediments such as coal.
Finally, paleontologists are able to find the fossils once they become exposed thanks to a process called erosion.
<span>Meiosis is a special type of cell division that reduces the number of chromosomes by half so that the resulting daughter cells have half a complement of chromosomes. The order of meiosis is: Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Cytokinesis, Prophase II, Metaphase II, Anaphase II, Telophase II, then cytokinesis again.</span>
