Answer:
D. Ligase
Explanation:
Ligase is an enzyme that can catalyze the fusion of two large molecules through the formation of a new chemical bond, which is usually accompanied by the hydrolysis of a small end chemical group.
Ligases play an important role in linking DNA breaks during excision repair, DNA damage, or spontaneous lesions such as basal sites or oxidized bases.
I believe the answer is a Meander. (beware that this is actually a geography question not a biology one, please put it in the right section next time and it will be answered quicker!)
Answer:
A.) I
Explanation:
The first one is the most likely to be solid at room temperature because it is the only structure depicting a saturated fat.
Saturated fats have no double bonds between the carbons in the parent chain. This allows the molecules to assume very compact positions, causing it to be solid at room temperature.
Unsaturated fats have these double bonds which bend the structure. These "kinks" in the molecule are what make unsaturated fats liquid at room temperature.
How diseases happens to spread in communities is the direct contact of bacteria, viruses or other germs from one person to another. This can happen when an individual with bacterium or virus touches, kisses, or coughs on someone who isn’t infected.
