This is true, a covalent bond is always a shared pair of electrons between 2 atoms. This is done to stabilize both atoms but making their outer energy level more or totally complete with electrons.

In humans, the maintenance of a stable internal temperature is a direct result of___________.
vampirchik [111]

The given question is incomplete. The complete question is:

In humans, the maintenance of a stable internal temperature is a direct result of___________.

a. detection of and reaction to stimuli in the  environment

b. digestion of starches and absorption of  protein from the internal environment

c. diffusion of water and excretion of glucose to  the external environment

d. transport of ATP and locomotion through  the environment

Answer:

a. detection of and reaction to stimuli in the  environment

Explanation:

Thermoreceptors present in skin layers of the human body sense the deviation of the body temperature from the normal range. As the body temperature rises above normal, the thermoreceptors send signals to the brain which n turn signals dermal blood vessels to dilate and sweat glands to secrete sweat. The heat from the body surface is lost to the surroundings to drop the body temperature towards the normal range.  

On the other hand, when the body temperature goes below the normal range, thermoreceptors send signals to the brain which in turn signals dermal blood vessels to constrict to conserve the body heat. If body temperature continues to drop, muscles are signaled to contract involuntarily to generate body heat to raise the body temperature towards the normal range.

Which of the following is not attached to the central carbon atom in an amino acidA. A carboxyl functional groupB. An amino func
gavmur [86]

Answer:

The correct answer is C. An oxygen

Explanation:

Amino acid is a compound which serves as the building block or proteins. They are the smallest and simplest unit of protein. They contain carbon, oxygen, hydrogen, and oxygen.  

Each amino acid has a central carbon atom which is designated as alpha carbon which is attached with a carbonyl functional group, an amino-functional group, a hydrogen atom, and a side chain(R group). So oxygen is not bound directly with the central carbon atom.

The R group is different in different amino acid. Glycine is the simplest amino acid and it has H in place of the R group.
