The answer is dusk and dawn.
Crepuscular animals are active during twilight (latin crepusculum). Twilight is a period after dawn and before dusk, so crepuscular animals want to avoid dusk and dawn. Animals' activity in different periods during the day depends on temperature or other biotic factors. It also depends on predators' activities or local competition.
Answer: significantly increases risk of stroke, sudden cardiac arrest, and death.
The other molecules are triglycerides, low density lipoprotein, and high density lipoprotein.
Adenosine triphosphate (ATP) connects anabolism and catabolism in cells by storing energy from catabolic reactions and providing that energy to anabolic reaction.
Adenosine triphosphate (ATP), also known as energy molecule, is found in animal and plants cells.
It plays a huge role in anabolic and catabolic reactions.
During anabolic reaction, simple organic molecule join together to form complex molecule by using energy.
For example, carbohydrates, fats, proteins and glycerol.
While in catabolic reaction, large complex molecules disintegrate to form small molecule and in this reaction a large amount of energy is released.
This energy is stored by the body cells for later use.

Eukaryotic transcripts (mRNA) have to undergo capping and splicing before it can be translated.
<h3>RNA processing:</h3>
1. An RNA transcript is first produced in a eukaryotic cell as a pre-mRNA, which needs to be converted into a messenger RNA (mRNA).
2. The RNA transcript is given a 5' cap at the start and a 3' poly-A tail at the end.
3. The process of splicing involves cutting out some RNA transcript segments (introns), then joining the remaining segments (exons) back together.
4. Some genes have the ability to alternate splices, which produces various mature mRNA molecules from the same beginning transcript.
The introns not only do not contain the information necessary to construct a protein, but they also need to be cut off in order for the mRNA to create a protein with the correct sequence. An mRNA with extra "junk" in it will be created if the spliceosome fails to remove an intron, and the translation process will result in the production of the incorrect protein.
