According to Darwin’s theory:

During human evolution, there was natural selection for the loss of body hair, as it enabled them to better stay cool and to therefore hunt throughout the day.

Early humans went from bodies covered in hair (Ex. Chimpanzee) to having mostly hairless bodies, excluding the heads and other areas.

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.

In translation, the cell uses the genetic information contained in mRNA to make the proteins that carry out the cell's work.
Jobisdone [24]

Answer: d). UAG

Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.

From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.
