Answer:

A replacement of a letter with different letter would indicate a missense mutation. (eg. GGA would become something like GCA and it would make something completely different).

Explanation:

A missense mutation is when the RNA replicates the instructions wrong from the DNA. When RNA is transcribed to make amino acids, it will make a completely different amino acid rather than the one that is needed/blueprinted. For example, if the sequence was AAG in the RNA (Derived from TTC DNA), it would create Lys amino acid. However, if the RNA sequence was AGG (Derived from abnormal TCC DNA), it would make Arg amino acid, which is different.

antoniya [11.8K]

Answer:

Metabolism consists of all the energy transformation reactions in an organism. (Ans. B)

Explanation:

Metabolism is defined as the total sum of the chemical reactions which synthesized in every cell of living things and provides energy for formation of new organic materials and vital processes (such as movement, growth, reproduction and development).

In living metabolism, enzyme mediated chemical reactions takes place. Energy which comes from nutrients and solar energy fueling multistep reactions and converting into the molecules which is necessary for maintenance and growth.

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot
Mama L [17]

Answer:

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."

Explanation:

The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact.  When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.
