Why do the cells of the digestive system secrete proteolytic enzymes, such as pepsin, in their inactive forms
Kipish [7]

Answer:

In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.

It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.

Why is mitosis incompatible with the production of sperm and oocytes
Naily [24]

Answer:

Mitosis creates diploid cells, while gametes (sperm and oocytes) are haploid cells

Explanation:

Mitosis is the process by which somatic (non-germ line) cells replicate, and two identical cells, called daughter cells are produced from each division. These cells are diploid, meaning that the cell has paired chromosomes. Meiosis is the process by which gametes, sperm cells and oocytes, are produced and these cells must be haploid, or contain unpaired chromosomes, so that when fertilization occurs, the chromosomes from the sperm cells and the chromosomes from the oocytes can recombine to create unique pairs of chromosomes for the resulting zygote. Thus, mitosis will never be able to create germ cells as germ cells must be haploid.

Which list below describes the next steps of evaporated water through the water cycle?
KATRIN_1 [288]

Answer:

The correct answer would be A. Condensation, precipitation, runoff, groundwater.

Water cycle explains the cyclic movement of water through the four spheres of the earth.

The water undergoes different physical states while moving through the cycle.

It starts with the evaporation by surface water is transported from the hydrosphere to the atmosphere in the form of water vapors. Transpiration and sublimation also lead to the formation of water vapors in the atmosphere.

The temperature keeps decreasing as the water vapors rise up in the sky. The lower temperature condenses the water vapors into tiny drops which form clouds and fog in the sky.

The tiny droplets accumulate to form bigger droplets and with the combined effect of temperature, wind, and gravity they precipitate in the form of rain, snow, frost, dew et cetera.

The water that falls on the earth surface then runoff into water bodies like stream, lakes, river, seas, and oceans.

Some of the water infiltrates into the soil and form the groundwater.
