Answer:
True
Explanation:
Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.
When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.
Answer:
D
Explanation:
A group or member of a species would overtime become differentiated from the original species that originate from if they occupy a different niche that has a different and unique environmental conditions. In an attempt to adopt to the condition of the new environment, they would develop specific features. For example, the honeycreepers having a bill that are well adapted to eat certain foods.
Therefore, the most likely conclusion the scientist would make is D.
Answer:
these chromatids separate longitudinally to become individual chromosomes.
one chromosomes is composed of and DNA molecule
Answer: a. True
Explanation:
The main aim of the IRB is to safeguard the right of the human subjects used for the purpose of research conducted by the governmental authority. It also emphasizes over the protection of the researchers from illegal complaints. The risks to the human subjects can be minimized by using procedures which cause no harm to them and a detail consent of the research practice should be taken from these subjects by informing the purpose of research.
Answer:
Cell X
Explanation:
Prokaryotes do not have a nucleus or any other membrane-bound organelles (including chloroplasts). So cell X is a prokaryote.
