Describe the relationship between chromosomes, messenger RNA, and proteins.

1 answer:

8 0

A chromosome is a packaged and organized structure containing most of the DNA of a living organism. Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

Please Help! Which material undergoes radioactive decay? A) all elements that have a half-life B) all elements that contain atom

Anvisha [2.4K]

Answer: C

Proof: This would be C because radioactive decay is when atoms and protons decide to slowly decay or separate from the atom. Therefore, they would produce radiation. Just like atomic bombs or nuclear waste. (Hope this helps-)

What are routes followed by nerve impulses as they pass through the nervous system?

n200080 [17]

Nervous system involves transmission of impulses from the receptors to the effector cells. it involves the detection of the stimuli by the receptor cells (includes the skin,eyes,mouth), then the stimuli is carried by the sensory neurone (joins the receptor cells and the spinal cord) to the central nervous system (the spinal cord), then the impulse is picked by the relay neurone and taken to the brain for processing, where the brain interprates the stimuli and sends a response. then the relay neurone from the brain joins to the motor neurone which connects the brain and the effector cells. The motor neurone carries the message to the effector cells (muscles and the glands), and finally a response is experienced in the specific place of the body by either movement of body muscles or secretions by the glands.

When a tastant enters the mouth, what are all the structures it passes on its way to

Bond [772]

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 TOT (tip) 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 taste buds on the tongue which are jagged, aiding in their ability to move food.

Fungiform papillae on the side of the tongue and filiform papillae located on the dorsal surface of the tongue come in contact with the tastant.

Both types of papillae have taste buds 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 facial nerve.

For taste buds located in the middle of the back of the tongue, signals travel through the glossopharyngeal nerve. The signals travel to the nucleus of the solitary tract of the brainstem, where they are relayed to the thalamus for higher processing.

When enough experimental data support a hypothesis, the hypothesis becomes alan)

vekshin1

B. theory

if many people perform the experiment and conclude the same things/ come to the same results, the hypothesis then becomes a theory. A theory is an idea that is widely accepted as true, but not 100% proven factual (ex: the theory of gravity)

Although cells have differences that reflect their specific functions in the body, what functions do they have in common?

madam [21]

All cells have a nucleus, which contains the genetic material of the cell. Also, all cells have a mitochondrion, the powerhouse of the cell. Finally, all cells have ribosomes, cell membranes, and cytoplasm. These parts of the cell do the same thing regardless of where they are in the body.
