During respiration, a seed metabolizes sugars. what is the source of the sugar metabolized by the seed?
pashok25 [27]

The source of the sugar metabolized by the seed is photosynthesis.  

The procedure used by plants to transform light energy into a chemical form of energy is known as photosynthesis. The chemical energy can afterward be discharged to fuel the plants to perform their activities.  

During photosynthesis, carbon dioxide and water can be combined in the existence of chlorophyll and sunlight to generate oxygen and glucose (carbohydrates). However, the prime component generated in the procedure is glucose (sugar) that is the molecule, which generates energy to mediate the activities of the cell.

A peptide has the sequence of Gly-Ser-Glu-Leu-Ala-His-Gly-Arg-Leu-Ala-PheCys-Leu. (pKR=4.25, 6.0, 8.2, 12.5. Assume pKa’s of ami
Aloiza [94]

Answer:

The correct answer is option a. "7.1".

Explanation:

One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.

Genes that are close together in the same chromosome:_________
Pepsi [2]

Answer:

C. tend to be transmitted together.

Explanation:

Independent assortment of alleles of the genes during anaphase-I of meiosis-I requires that the genes should be present on different chromosomes. The genes that are present on the same chromosomes deviate from the independent assortment. These closely placed genes are called linked genes. They move from one generation to next together and do segregate randomly. This results in the generation of more proportion of the parental types in the progeny. The linked genes may be present on both autosomes and sex chromosomes.
