Answer:
The correct answer will be option-The mice will die. Transformation of genetic material from R to S was required.
Explanation:
Frederick Griffith performed an experiment on the mouse using two strains of the <em>Streptococcus pneumonia</em> which are R (rough avirulent strain) and S (smooth-virulent strain).
In the experiment when he injected the live S bacteria with dead R bacteria, the mice died, opposite of the expected result that mice would not die. This amazed Griffith and he concluded that some transformation of the bacteria has happened due to which the mice died. The R bacteria became S bacteria (virulent) due to the transformation which was proved later that the bacteria took the DNA of the dead S bacteria from the surrounding.
Thus, the selected option is the correct answer.
Question:
Albinism in blue jays is a recessive trait. Over time, the percentage of albino blue jays in a population will remain stable in a population from generation to generation if which conditions are met?
Answer:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Explanation:
If frequencies stabilize in the population, generation after generation, then it means the population met Hardy-Weinberg equilibrium. Populations in H-W equilibrium will get the same allelic frequencies generation after generation.
Hardy-Weinberg assumption for a population in equilibrium:
• Random matings: Any individual get crossed with any other individual
• No superposed generations: each individual can leave their gametes in the pool only once.
• No mutations: No mutations originate in any new gametes.
• No migration: No incorporation of gametes from other populations
• Infinite population size: the probabilities of randomly taking an A gamete from the pool are p, and the probability of taking a B gamete is q.
• No natural selection: Each individual has equal surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
<span>The answer to this question is no, everything that is ingested needs to be metabolised, unless it is a medicine specifically formulated for oral adsorption directly into the bloodstream, or in this instance the energy source is a ketonic monosaccharide. Because it is so small and a simple structure, it can enter the blood barrier directly and the body can then use this as energy.</span>
