Answer:
Hypothalamus
Explanation:
The hypothalamus is a part of the brain which possesses temperature receptor cells that detect changes in the man’s temperature, thereby sending signals in the form of electrical nerve impulses to the man’s muscles and nervous system, which in turn respond in counteracting the drop in the normal temperature of the body.
Once the muscle cells of this man receive these signals, they produce heat through thermogenesis by shivering when the muscle cells begin to contract. This is one of the mechanisms by which thermoregulation is achieved as controlled by the hypothalamus in the brain of the man.
Answer:
D) Urethra is the correct answer
Answer:
In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.

Answer:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, ATP is produced directly in the reactions that transform glucose. However, more ATP is later produced in a process called oxidative phosphorylation.
Archaea differ from bacteria in that archaea lack peptidoglycan.
<h3>
What about archaea and bacteria?</h3>
- Although archaea lack internal membranes, they do have a cell wall and swim by using flagella.
- The difference between bacteria and archaea is that bacteria have an ester-linked cell membrane, while archaea have an ether-linked cell membrane.
- Organelles and other internal membrane-bound structures are not present in the cells of bacteria and archaea.
- In contrast to eukaryotes, bacteria and archaea do not have a nucleus that separates their genetic material from the rest of the cell.
- Similar to Eubacteria, Archaea have a polysaccharide and glycoconjugate-rich cell wall.
- The strong cell borders that archaea form despite not having peptidoglycan make them resistant to high internal osmotic pressure.
