Answer:
Modified apocrine sweat glands
Explanation:
The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.
As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.
This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
Answer:

4) - F)
Explanation:
<u>Transferases (B)</u>: Transeferases is the class of enzyme that catalyzes reactions involving the <u>transfer of certain functional groups. (1)</u>
Example: Transaminase transfers nitrogenous groups
<u>Isomerases (E)</u>: Isomerases is the class of enzyme that catalyzes <u>isomerization reactions and intramolecular rearrangements. (2)</u>
Example: Triosephosphate isomerase interconverts aldoses and ketoses
<u>Oxidoreductases (A)</u>: Oxidoreductases is a class of enzyme that catalyzes <u>redox reactions (3) </u>which involves the simultaneous transfer of electron.
Example: Alcohol oxidoreductases acts on the alcohol functional group
<u>Ligases (F)</u>: Ligases is a class of enzyme that catalyzes reactions involving <u>chemical bond formation between two molecules. (4)</u>
Example: DNA ligase joins DNA fragments
The original source of all energy in a food web is the sun. the sun provides light energy that producers use in photosynthesis. animals eat the producers and other animals eat those animals. the energy flow goes up the web, but it all originated at the sun
