Answer:
A and C
Explanation:
they provide food and have helped with medicinal discoveries
Answer:
kinetic energy
Explanation:
When the molecules or atoms of a substance have high kinetic energy, the atoms/molecules move rapidly and collide frequently and harder. Most collisions are inelastic meaning that some of the energy in the collision is lost mostly as heat. This is why increasing the kinetic energy of a substance’ atoms/molecules causes the temperatures of the substance to rise. This is how heating by magnetic induction works.

The given question is incomplete as the option are not provided however, the correct options are as follows:
Defective proteins are often degraded quickly, making their effects temporary.
Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.
Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.
Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.
ch mRNA molecule is only translated once and then degraded
Answer:
The correct answer is - statements 1, 3, and 4.
Explanation:
DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.
RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited
The process of transcription is quick.
Answer:
Factors than can decrease the risk of esophageal cancer include intake of FOODS THAT ARE HIGH OR RICH IN VITAMIN C
Explanation:
Esophageal cancer can also be known as the cancer of the oesophagus.
Esophageal cancer is caused by either genetic reasons or by a continuous smoking activity. Sometimes when people experience a terrible acid reflux in their system, there is a tendency they might have esophageal cancer.
Common symptoms of esophageal cancer includes:
a. Heart burn
b. Indigestion
c. Unexpected weight loss
d. Pain in the chest area
e. Consistent coughing
f. Pain and difficulty with swallowing foods.
Esophageal cancer can be effectively managed by
a) Used of chemotherapy
b) Use of other kinds of drugs.
c) Consumption of fruits that are rich in vitamin C.
