Answer:
The rate of photosynthesis is at a maximum over a narrow range of light intensities.
Explanation:
Light provides the energy required to drive the process of photosynthesis. Starting from a low light intensity, the rate of photosynthesis increases as intensity increases. Hopefully helps ig
Answer:
Phenotypic changes:
When Rhodobacter is cultured in total darkness for multiple generations, the ability to produce it's own photopigment reduces with time with little or no ability to undergo its own photosynthesis due to absence of enzymes or pigment for photosynthesis.
It becomes expensive for the Rhodobacter to undergo photosynthesis. This allows mutants that can grow in the dark to take over from the culture grown in the dark.
Evolutionary processes:
It's natural selection that allows the fittest organism to survive. As in the case of the mutants
There are three phases of stem cells mitosis, gene expression, and differentiation.
<h3 /><h3>What are stem cells?</h3>
Stem cells that are totipotent or omnipotent. programmable stem cells. Multiple-potency stem cells, stem cells with oligopotency, the body's building blocks are stem cells, which are cells that give rise to all other cells with specific roles.
Daughter cells are created when stem cells divide properly in the body or a lab to create additional cells. Most stem cells are found in the bone marrow.
They divide at this stage to produce new blood cells, Once fully developed, blood cells leave the bone marrow and travel into circulation.
Therefore stem cells develop into different cells through differentiation.
