How does sweating during exercise help maintain homeostasis?
natima [27]

The correct option is B. It regulates body temperature.

<h3>What is homeostasis?</h3>

In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.

  • This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range).
  • Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.
  • Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms.
  • All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.

Assuming that transcription and translation both proceed from left to right, which is the correct orientation of the DNA templat
aleksklad [387]

The correct answer is:

DNA template 3'– ……… –5'

RNA transcript 5'– ……… –3'

Protein product H2N– ……. –COOH

In nucleic acids, DNA and RNA 5’ end refers to phosphate group attached to the 5′ carbon of the ribose ring, while 3’ end refers to the ribose -OH substituent. Nucleic acids can only be synthesized in the 5′-to-3′ direction, which means that the DNA template is 3’—5’. Translation of the protein by the ribosome will also proceed in a 5′ to 3′ direction, which means that the mRNA template is 3’—5’.

The protein during the synthesis is extend from its N terminus toward its C terminus.
