Answer:

an amino group, carboxyl group, hydrogen atom, and a side chain bonded to the central carbon atom  

Explanation:

An amino acid essentially comprises amino group (-NH₂), carboxyl group (-COOH), hydrogen atom (-H), and a side chain (represented by R) which are attached to a central carbon atom. The central carbon atom to which all of them are attached is known as alpha carbon (α carbon). The bonds that -NH₂ and -COOH make with α carbon are known as phi (Ф) and psi (Ψ) bonds respectively.

The structure of a typical amino acid is depicted as under:

          H

            |          

H₂N  -  C  -  COOH

            |

           R

The position of -NH₂ and -COOH decide whether it is a L amino acid or R amino acid.

Answer: C. An amino group, carboxyl group and a side chain bonded to the central carbon atom.

Explanation: The amino acid structure consists of amino group, a carboxyl group (Acid group) and a side chain. These three groups are bonded to a central carbon atom.

Which choice below best describes the factors that can affect an ecosystem’s stability?
kirill [66]

Predator and Prey relationships would have the most effect on an ecosystem's stability because they keep a limit number on the opposing population (ex. rabbit population can only get so high because wolves keep eating them / wolf population can only be so high because there is't enough rabbit to eat)

What is anthrax? how was anthrax used in the crimes?
love history [14]
Anthrax is a rare bacterial disease spread by animals, insects, and mosquitoes. Victims may feel ill or have skin ulcers and difficulty breathing. I believe that you can find how it was used in a (story I believe in your case) by trying to find its significance of it to the story. Try to imagine what the story would be like without it? Does it change the ending? 

Hope this helps!

Animals that maintain internal body temperature using heat generated by their own metabolism are called
denpristay [2]

Answer:

Explanation:

The complete question is as follows :

Animals that maintain internal body temperature using heat generated by their own metabolism are called:

A)thermoregulators.

B)hibernators.

C)aerophiles.

D)endotherms.

E)dormants.

  • An animal that is capable of maintaining a body temperature that is metabolically favorable for the organism is known as an endotherm.
  • The body temperature is maintained by an endotherm by using its internal body capacity to generate heat rather than depending on the ambient temperature.
  • Some of the mechanisms used by endotherms to maintain a suitable internal body temperature include shivering, uncouple oxidative phosphorylation, sweating, flushing, etc.
  • The endotherms include birds and mammals.
  • The ability to perform endothermy is owed to the presence of a large number of mitochondria that enables the organism to increase the rate of metabolism to generate heat as and when required.
