Nonvirulent bacteria can still be transformed into virulent bacteria if it is combined with debris from heat-killed virulent bacteria that is first treated with RNase, protease, or no enzyme because these are important factors for the establishment of virulence and are often required when bacteria modify their genetic record in response to the conflicting or adverse situations.
Answer:
Genetic diversity is important because it allows organisms to adapt to changes around it, thereby preventing extinction- <u><em>True</em></u>
Explanation:
Genetic diversity is one of the main reasons that brings about the survival of an organism in an ecosystem. As alleles of a gene assort independently during gamete formation, this phenomenon brings about genetic diversity. The genetic diversity allows organisms with better traits to survive and hence, they become better adapted to live in a habitat. As the organisms with better traits survive, extinction of species becomes lesser through this phenomenon.
They are performed when both lungs give out. the risks are death.
The short answer is that cell death by apoptosis in various phases of cell cycle depends on the cell-type and inducer/stimulus. Hematopoietic cells can undergo apoptosis at all stages of cell cycle as noted by Bertrand. However, mesenchymal or epithelial cells usually undergo apoptosis at the G1/S or G2/M phase of the cell cycle.
The answer is C. Succession returns a disturbed
ecosystem to a more stable state. This is also classified into two (2) types:
Primary Succession and Secondary Succession. The Primary succession arises when
a new land is transformed and a bare rock has been exposed providing an environment
that can be occupied for the first time. While, secondary succession occurs
when a previously occupied environment was disturbed that kills much of all its
community.
