Answer:
Option 1, 0
Explanation:
Complete question
Flower color in the varieties of pea plants studied by Mendel is controlled by alleles at a single locus. A group of peas homozygous for purple flowers is grown in a garden. All flowers are purple, yet there is some variation in the intensity of the purple color. The estimated heritability for this observed variation in flower color would be
- 0.
- 0.5.
- 0.75.
- 1.
- Cannot be determined without additional information
Solution
Given all the pea plants in the garden are homozygous purple (PP)
If we cross two PP parents, the following offspring will be produces
PP * PP
PP, PP, PP, PP
This means that all offspring are also homozygous purple.
Thus, chances of inheriting variation in the purple color of offspring are negligible. However, the variation in their color can be due to their individual interaction with the variable factors in the environment
Hence, option 1, 0 is correct
Enzymes and acidic juices in the stomach, which break proteins down into smaller molecules, is known as proteolytic enzyme.
Proteolytic enzyme (also known as protease) is any group of enzymes that break down the long chainlike proteins molecules into smaller molecules (peptides) and later into amino acids. In the stomach, protein digestion takes place. The three main proteolytic enzymes; pepsin (produced by the stomach), and trypsin and chymotrypsin (produced by the pancreas) breaks down proteins into polypeptides which are eventually broken down into amino acids by several exopeptidases and dipeptidases.
For the first question the answer is D. Systemic
For question number 2 the answer is B. Lungs
I think the correct answer would be D. The specialized structure that helps a vascular plant to soak up water after a rainfall in a desert would be the extensive shallow root system with root hairs. An example of this would be the cactus. It has a root system that is very different from any plant that is not found in the desert. The roots are found just exactly below the surface. It is ready anytime to suck up water from rain or snowfall and transport it to the stem of the plant. Also, after a rain, the cactus would grow tiny roots in its body to aid in the absorption of water more quickly.
