Answer:
<u>C) They may provide selective advantages.
</u>
<u>D) Slight differences in the genetic code may have significant results.</u>
Explanation:
The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.
DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.
Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment. Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.
Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!
Explanation:
Shivering as a natural, involuntary response to generate heat is an example of maintaining homeostasis by regulating body temperature.
Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.
When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.
The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.
Hopes this helps happy early Christmas!!!! :D
