True, centrioles can be found in animal cells
Answer:d.are eventually replaced by electrons from photosytem 11
Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen
Answer:
b. become part of the body's structural systems.
Explanation:
- Minerals are the inorganic regulators needed for different functions inside the body.
- Minerals donot provide energy but involved in generation of energ through their metabolic function. (Hence option A is excluded)
- They provide a good medium for the protoplasmic activities (permeability of cell membrane and normal functioning of cell)
- Maintaining bod fluid balance.
- For structural units.
- Cannot be degraded in the body neither can be destroyed while cooking ( Hence option c and d are excluded)
- They become the part of the body's strctral systems (Hence option B is the right answer)
answer: binary fission
explanation:
binary fission is when a single celled organism divides to asexually reproduce two new organisms
