The tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts. So, your answer will be the Tricuslid Valve. Hope I helped!
The answer is <span>Meiosis I.</span>
<span>Meiosis is a cell division which results in the reduction of chromosome
number by half - from diploid to haploid - in daughter cells. It consists
of meiosis I and meiosis II. Meiosis I produces two
haploid cells. Meiosis
II is analogous to mitosis, so each of these two haploid cells will in meiosis
II produce two haploid cells. In total, meiosis results in four haploid cells.</span>
<span>
</span>
<span>Therefore, the production of two haploid daughter cells is in meiosis I.</span>
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)
<span>Carbon-based macromolecules are found in all life forms.</span>
It's biotic, biotic is basically anything living
