Answer:
produced during meiosis. Which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.
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.

Answer:
The gene of interest from another source.
Explanation:
A plasmid is a small, circular double-stranded extrachromosomal DNA molecule within a cell particularly a bacteria cell that is physically separated from chromosomal DNA and can also replicate independently.
Expression vector is usually a plasmid (or a virus can also be utilized) constructed to allow for gene expression in cells. The vector is used to introduce a gene of interest into a target cell, and can drive the cell's mechanism for protein synthesis to produce the protein encoded by the gene, thus giving rise to the expression of the gene.
This gene of interest is integrated into the plasmid that is cut by endonucleases and then ligated using DNA ligase. Thus the expression differs from the normal plasmid in that it contains an external gene sequence.
Answer:
Dessert and tundra
Explanation:
Theses two biomes get very little rain and because of this they have a less diversity of fauna and flora.
The differences are that a tundra is very dry and extremely cold and on the other hand a desert is very arid and hot and it can go as high as 54°C (130°F).
