Answer:

The thermal energy will flow from the computer to the person.

Explanation :

Usually computer are such devices which converts electrical energy into thermal energy and then it gets transferred to the person. The energy flows from the higher amount to lower amount. In this case, computer is producing higher thermal energy than the person that’s the reason for the flow of energy from computer to the person.

The chemical mechanisms used to avoid errors in protein synthesis are different from those used during DNA replication. DNA poly
Savatey [412]

Answer:

(C) Aminoacyl-tRNA synthetases have an additional active site that binds to non-cognate tRNAs. The tRNAs that bind to this second active are hydrolyzed and released from the enzyme.

Explanation:

In case of translation, proof reading is done by aminoacyl-tRNA synthetases only. Aminoacyl-tRNA synthetases have two mechanisms to avoid error during translation which are mentioned as under:

<u>(1) Chemical proof reading:</u> Incorrect amino acids rather than being hydrolyzed in catalytic pocket get hydrolyzed in editing pocket and thus they hardly get attached to tRNA.  

For example: For distinguishing similar amino acids like isoleucine and valine, isoleucyl-tRNA synthetase uses a second active site which is meant for only valine not for isoleucine. In this particular site, valine which had entered the enzyme is cleaved away with the help of editing reaction after which the enzyme is well prepared to process isoleucine which is the correct amino acid for this enzyme.

<u>(2) Kinetic proof reading: </u>Even if an incorrect amino acid has entered a particular aminoacyl-tRNA synthetase, it does not cause appropriate conformational change in the enzyme because of which the incorrect amino acid loosens from the enzyme and does not get incorporated.

Note: In this example, only chemical proof reading is mentioned not kinetic proof reading.

Bezzdna [24]

Answer:

four phenotypes appear in the ratio 9:3:3:1

Explanation:

<em>For a dihybrid cross in which the two genes concerned obey simple dominant/recessive law and are independently assorting, </em><em>four phenotypes are produced in the ratio 9:3:3:1. </em>

The dominant gene takes up the largest ratio (9/16) while the recessive gene takes up the smallest (1/16). Any deviation from 9:3:3:1 and the number of phenotypes produced from a dihybrid cross is an indication that the genes involved do not obey Mendelian laws.

Which are come of the advantages of body segmentation?
Len [333]

Answer:

b. Segments can become specialized on a particular function

Explanation:

Segmentation conditions virtually every aspect of the structure and functioning of animals with a consecutive body. Generally speaking, we can say that the main advantage of segmentation is that each segment can become specialized in a specific function.

One of its advantages is related to locomotion and comes, on the one hand, from the fact that the volume of celiac fluid remains constant in each compartment, acting as an antagonistic force against which muscles can act and, on the other, from the possibility of independently control each segment . This allows the peristaltic movement (circular muscle contraction wave followed by longitudinal muscle contraction) to be localized and involve only those muscles that are strictly necessary, making the movement's energy needs considerably more profitable.

The compartmentalization of the body led to the repetition of structures, namely excretory, nervous and circulatory in each segment. This can be seen as another advantage of segmentation as it may lessen the impact of damage to the animal's body; Undamaged segments can maintain their normal functions and thus increase the likelihood that the animal will overcome the damage sustained.

Another advantage is that segmentation allows modification of certain portions of the body to perform specialized functions such as feeding, locomotion and reproduction.
