Answer:
''If the old cells inoculated in chicken, it produces resistance in the chicken against new V. cholera cells.''
Explanation:
From the data provided by Louis Pasteur, we make a hypothesis i. e. ''If the old cells inoculated in chicken, it produces resistance in the chicken against new V. cholera cells.'' From these observation we can assume that by allowing old V. cholera cells to chicken, it did not cause any disease but make immunity against the new V. cholera cells which are more effective from old V. cholera cells.
It’s called a rock avalanche
Answer:
See below
Explanation:
A) First of all, it must be considered that HIV has a RNA genome.
The reverse transcriptase is a viral enzyme able to convert a RNA molecule (in this case the RNA would be the viral genome) to DNA. This process is important for two reasons:
* The DNA molecule is more stable than RNA --> Therefore, there is a higher likely that the molecule wouldn't be degradated by the host.
* The viral genome made of DNA will be integrated into the host genome --> To do so, it requires to be DNA instead of RNA
B) The inibitor is able to target the Reverse Transcriptase --> So, the likehood of converting RNA to DNA is lower. In this case, the single RNA molecule is less stable than the DNA and the host can degradate it more easily.
C) In general, the viral will not survive the treatment and, hence, the patient will not suffer from the viral infection
Question 9: The right answer is B (the second one)
The two major types of cellular, prokaryotic and eukaryotic organisms.
* Prokaryotes are identified with bacteria: most live as single-cell organisms but some bacteria associate in a chain. Prokaryotes have their DNA in the cytoplasm of the cell.
* Eukaryotes have a nucleus, a compartment separated from the rest of the cellular contents, which contains the DNA.
Question 17: The right answer is incomplete dominance.
Incomplete-dominated genetic action is a type of genetic action where one of the alleles outweighs the other in the production of qualitative phenotypes, without the dominant allele completely overshadowing the heterozygous recessive allele. Two copies of the dominant allele are required to produce the dominant phenotype. Since the recessive allele can perform its function at the heterozygous stage, this genotype produces a phenotype (the heterozygous phenotype) which differs little from the dominant phenotype.
In our case the phenomenon of incomplete dominance gave a pink color (between white and crimson) instead of crimson color when the white flowering plant was mixed with the crimson flower plant.
Question 19: The right answer is Speciation occurs gradually.
Speciation is a term that means the formation of new species.
Gradualism is an evolutionary theory according to which new species occur by gradual transformation of ancestral species, by evolution.
These transformations are slow and regular. Otherwise expressed: evolutionary theory according to which speciation is gradually effected by small successive changes over long periods.
Answer:
B) It can produce coagulase
