<span>Transpiration is considered as necessary evil because during CO2 and other gaseous exchange, water also escapes and that could be harmful to the plant.</span>
The answer is 99.
Amino acids <span>contain a carboxyl group (carbon-containing) and an amino group (nitrogen containing). Proteins are made by forming peptide bonds between the carboxyl and amino group of amino acids.
</span>If a protein is made of 100 amino acids, that means there are 99 peptide bonds (because the last, 100th amino acid will not bind the next (101st) amino acid). For each peptide bond that is created, one oxygen atom and two hydrogen atoms are taken. Therefore, one water molecule is created for each peptide bond. If there are 99 peptide bonds, 99 water molecules are created.
Hello there!
The helmet-like region of the sperm that is similar to a large lysosomr and assists penetration of the egg is called the Acrosome.
The correct term would be "Acrosome".
Hope this helps!

Answer:
1.Small cell: has larger surface-area to volume ratio
Bigger Cell: has little space to volume ratio
2. Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.
Amoeba and some bacteria's are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area.
Where as humans have small surface area: volume so diffusion is very slow or does not take place at all.
3. Diffusion and Cell Size
The larger a cell is, the greater the surface area available for diffusion. ... Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.
