Answer:
Cleavage is a process in which cell is divided into several parts without increasing in size. There are 4 stages of cleavage i. e. 2-cell, 4-cell, 8-cell and 16 cell stages. 2 cell embryo cleavage occurs after 30 hours of fertilization. 4 cell embryo cleavage occurs after 48 hours. 6 cell embryo cleavage occurs on third day of fertilization. 8 cell embryo cleavage occurs on fourth day of fertilization and more than 100 cells are formed.
its answer is A.

The right Answer is <u>NITROGEN </u>
Nitrogen is quantitatively the most important nutrient that plants acquire from the soil. It is well established that plant roots take up nitrogen compounds of low molecular mass, including ammonium, nitrate, and amino acids. ... Intact protein also was taken up into root cells most likely via endocytosis.
Thus I prove that my answer is true.

Answer:
The process that releases ATP by breaking down glucose into ethanol and carbon dioxide is known as B alcoholic fermentation.
Explanation:
Alcoholic fermentation is an anaerobic process that deals with the breakdown of glucose into ethanol and carbon dioxide along with ATP generation.
First of all glucose molecule is Catabolized to pyruvate by glycolysis pathway.The so formed pyruvate is reduced to Acetyldehyde and carbon dioxide by the catalytic activity of Pyruvate Decarboxylase enzyme.
in the final step Acetaldehyde is undergo further reduction to generate ethanol by the help of Alcohol dehydrogenase enzyme.
This two reduction steps helps in the regeneration of oxidized NAD+ .
