lina2011 [118]3 years ago
5 0
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three stages

Vitamin d _____.
svetlana [45]
Vitamin D plays a vital role in the regulation of calcium deposits and maintenance of the phosphorous levels in the blood which are two elements that are significantly important for maintaining healthy bones.

The human body needs vitamin D to absorb calcium in the intestines and to recover calcium that would otherwise be excreted through the kidneys. It also essential for the development and strengthening of bones and it blocks the release of parathyroid hormones.

The answer would be letter E. None of the above

A mitochondrion has just been engulfed by a cup-shaped isolation membrane as it undergoes mitophagy. Before lysosomal fusion, ho
harkovskaia [24]

Answer:

Option-C

Explanation:

Mitophagy refers to the process which is evolutionarily conserved in the organisms to remove the dysfunctional mitochondria in the cell.

The mitochondrial is degraded by the digestive organelles by engulfing the mitochondria.

The mitochondria are engulfed by the lysosome and then phagosome is formed which is double membrane structure. This phagosome matures into the autophagosome and now has the mitochondria engulfed.

Since the mitochondria contain toe layer and during mitophagy engulfed by the phagosome, therefore, there is a total of four-layer.These four layers separate the matric of the mitochondria with the cytosol.

Thus, Option-C is the correct answer.

The row of energy in a grassland ecosystem is shown
bixtya [17]

The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.

<h3>Trophic Level</h3>

The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.

More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.

In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.

Round seeds are dominant over wrinkled seeds in
antoniya [11.8K]

Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)

Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)

<h3>How explain your answer?</h3>

Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.

Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.

If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.

Thus, this could be the answer.
