The information given about taste and the tongue is explained below.
<h3>
How to explain the tongue?</h3>
The food enters the mouth passing the <u>TOT (tip) </u>of the tongue. It is moved around by the motion of the tongue and teeth as the food is chewed. Its movement is facilitated by the<u> taste buds</u> on the tongue which are jagged, aiding in their ability to move food.
<u>Fungiform papillae </u>on the <u>side</u> of the tongue and<u> filiform papillae</u> located on the dorsal surface of the tongue come in contact with the <u>tastant</u>.
Both types of papillae have<u> taste buds</u> that have receptors for individual tastes -sweet, sour, salty umami (savory), and bitter. Once a tastant is bound to the receptor it creates a signal that travels through one of the three carnival nerves depending on the location of the taste buds. For taste buds located on the front of the tongue, the signal travels through the <u>facial nerve</u>.
For taste buds located in the middle of the back of the tongue, signals travel through the <u>glossopharyngeal nerve</u>. The signals travel to the nucleus of the solitary tract of the brainstem, where they are relayed to the thalamus for higher processing.

Can you show choices? but i think it may be peripheral
C. either a proton or a neutron
Good luck!
Tissues are below complex organs.
<h3>What are the tissues?</h3>
- The body is made up of four different types of tissue: epithelial, connective, muscular, and nervous. Each has a purpose for which it was created.
- Connective tissue, epithelial tissue, muscular tissue, and nerve tissue are the four fundamental forms of tissue. Other tissues are held together and supported by connective tissue (bone, blood, and lymph tissues). A coating is provided by epithelial tissue (skin, the linings of the various passages inside the body).
- Tissue that gives bones their strength and structure. Compact tissue (the tough outer layer) and cancellous tissue make up bone (the spongy, inner layer that contains red marrow). Osteoblasts, which build new bone, and osteoclasts, which break down existing bone, maintain bone tissue.
- Blood tissues can be found inside blood vessels, including arteries, arterioles, capillaries, venules, and veins (for more information on the names of individual blood vessels and the course the blood takes, see systemic circulation), as well as inside the heart's chambers.
To find the level is just below organs in complexity:

Answer:
Explanation:
Since Mark's wife was a carrier, it means that she is heterozygous for the trait. And after Mark got tested, they decided to have children due to no increased risk if they do have children, it means the condition is not an autosomal dominant condition but a recessive condition because if the condition is dominant, only one copy of the affected allele is needed to increase risk.
Thus, with a no increased risk, it means Mark is normal i.e. carries no copy of the recessive allele.
