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:
NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits.
Explanation:
The correct answer is: C) secreting releasing and inhibiting factors into a tiny portal system.
Hypothalamus is part of the brain that consists of many nuclei and has the function to connect the nervous system to the endocrine system via the pituitary gland. Hypothalamus is linked with the anterior pituitary via hypothalamic–adenohypophyseal axis. Releasing hormones or factors produced in hypothalamic nuclei are first released from the prolongation of the hypothalamus and then into a tiny portal system called hypophyseal portal system. This system of blood vessels transports hormones to the anterior pituitary where they act on the secretion of adenohypophyseal hormones.
3) a glacier because a river would be a V shape, mud flow would cause the valley to have flat bottom
Answer:
The flowchart that identifies an animal as herbivore or carnivore is attached as an image and discussed as follows:
Explanation:
Suppose we have two animals an elephant and a lion, now the flow chart for the elephant would be as follows:
start -- Read the name of the animal (elephant) -- Does it eat only plants?---Yes--Print Herbivore-- end
Now, the flowchart for the lion would be as follows:
start -- Read the name of the animal (lion)--Does it eat only plants?---No---Print Carnivore-- end
Thus, these are two examples given above to make a flowchart to find and classify an animal as herbivore or carnivore.
