which of the following would be the best method of doing so?
(a) carry out a survey of people with normal bone density to find out whether they
take Vitamin D tablets or not
(b) compare the bone density of two groups of people with low bone density after
providing only one of the groups with Vitamin D
(c) compare the incidence of people with low bone density in two different populations
(d) carry out an experiment in which a group of people with normal bone density are
exposed to very little sunlight to prevent the production of Vitamin D
Answer:
The correct answer is- Synthesis(S) phase
Explanation:
Interphase is the phase where cells spend most of their time. It is known as the resting phase and contains 3 stages called G1, S, and G2 phase. In G1 phase cells grow in size and produce those enzymes which are required for DNA replication.
In the synthesis phase, the DNA is replicated and gets doubled. This event is very important in the cell cycle because it allows each cell produced after cell division to take an equal amount of genetic material which is identical. Therefore in the cell cycle DNA replication occurs in the synthesis phase.
True or False
Answer:
Parasitism
Explanation:
Parasitism is the association between two organisms in which one organism (parasite) is benefited while the other (host) is harmed. The parasite is a heterotrophic organism that derives its nutrition from the living tissues of the host organism. In the given example, tick suck blood from their host and are exhibiting parasitism.
