Answer:
In the human body, cells are the basic units of life. Groups of cells working together for a specific function form tissues. Organs are two or more tissues operating together. Even separate organs work together, forming body systems.
Olfaction is not a tactile sensation, nor it's related to chewing food.
Olfactory receptors are chemical receptors in the nasal cavity that react with different odors creating the sense of smell that is interpreted in the brain.
So, olfaction is a chemical sensation that we experience while inhaling different odors through our noses.
Answer: silent mutation: a nucleotide base in a codon is replaced with a different base BUT the resulting amino acid isn’t affected.
Missense mutation: similar to a silent mutation, the only difference is that the switch of the nucleotide DOES result in a DIFFERENT amino acid
Nonsense mutation: a nucleotide base is changed, but that change results in a premature stop of translation
(Remember that after transcription, you are left with a strand of mRNA that Is then translated into a protein. The mRNA is read in increments of three nucleotide bases (A,U,G, or C) which is called a codon. That codon makes a single amino acid, and a strand of amino acids makes a protein)
Answer:
B) sugars; leaf; apical meristem
Explanation:
Phloem is one of the vascular tissues and is mainly involved in the transport of sugars. Phloem sap is the aqueous solution that moves through sieve tubes of phloem. Phloem sap mainly consists of sugars but also carries amino acids, hormones, and minerals. Sucrose is the most prevalent sugar.
Phloem sap moves from sites of sugar production (called sugar sources) to sites of sugar use or storage (called sugar sinks). A sugar sink is an organ that either uses the sugars for energy production and other functions or stores it.
In late spring, the fully grown leaves serve as a source of sugars. Apical meristem is responsible for the growth of stem and root length and serves as a sugar source as it obtains sugars from the leaves and uses them during the growth of shoot and roots.

You sneeze
Explanation:
I think so, when the cilia clears the germs you sneeze
