Answer:
The insect pictured is in the order coleoptera
Answer:
Coelenterates are the first invertebrates to develop a true nervous system.
Explanation:
Answer:
At least 17 PCR cycles or 16 PCR cycles
Explanation:
As we know -
In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.
The general mathematical representation of this is
where "n" is the number of PCR cycles.
It is given that DNA strands to be produced is 16 times the original quantity of DNA.
So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA
The chloroplasts had inner membrane
Explanation:
The primitive photoautotrophs utilized hydrogen sulphide as the electron donor to perform photosynthesis for energy production.
Later upon understanding the endosymbiotic relationship of cyanobacteria which resided in the mitochondria of a eukaryotic host cell, the use of chloroplasts for photosynthesis was understood.
Generations after generations led to the development of chloroplasts by the cyanobacteria due to this symbiotic relationships which developed into the chloroplasts.
The unique presence of the inner membrane and its components like the stroma, thyllakoids helped the organism to utilize water as the electron donor for photosynthesis like the present day eukaryotes. This is the main reason why cyanobacteria is considered as the ancestor for eukaryotes.
Answer:
The function of carotenoids in plant is the dissipation of excess light energy.
Explanation:
Carotenoids are a group of chemicals that are found in food, the chemicals possess antioxidant properties, which help the cell to get rid of radical species. Carotenoids are also presents in plants. In plants, carotenoids help the plants to absorb energy from sunlight to carry out photosynthesis. They also protect chlorophyll in plants from been damaged by the sun.
