g Riboswitch is a mechanism of gene activity regulation by mRNA conformation. Riboswitch can regulate ______.

Biology
1 answer:
Nastasia [14]3 years ago

Answer: c. both transcription and translation

Explanation:

Riboswitchs are mRNA elements that influence the activity of genes certain genes by regulating same and are found in other organisms apart from humans such as bacteria, plants and fungi.

They regulate activity by binding to specific small molecules known as ligands thus causing a structural rearrangement that enables either transcription or translation to be modulated in the gene.

Answer:

Explanation:

1. C

2.

A) Authotropic

B) The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration.

C) Oxygen

3. Photosynthesis. Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

A group of single-cell organisms collected from the ocean was brought into the lab for examination. The lab assistant was concer
jolli1 [7]

The correct answer is C. She added water that was hypotonic to the culture of organisms, and they ruptured.

Explanation:

In biology, a hypotonic solution is a substance with less concentration than the inner concentration in cells, this is the opposite of a hypertonic solution that has a higher concentration. Additionally, if cells are in hypotonic solution water or liquid will begin to get into them and this would make cells burst and finally explode and die due to the pressure in them.

This occurred in the case presented as it is likely the organisms collected from the ocean had a high concentration and therefore hen they were exposed to clean water in which concentration was lower, water entered into the cells and made them explode, which explains the only remains of them were bit and pieces.

Do prokaryotic organisms carry out<br> cellular respiration? If so, how?
Stella [2.4K]

Hi

Do prokaryotic organisms carry out  cellular respiration? If so, how?

The answer is yes as well as no, because some prokaryotes like Archeae and some bacteria donot use cellular respiration because they are anaerobic. The Archaea are also known as Methanogens that reduce Carbon di oxide from environment to Methane that is eventually oxidized to NADH (that is used as an energy source).

However, there are some bacteria that use cellular respiration as a source for the energy production.Cellular respiration is a process which occurs in the cells of higher living organisms as well as in cells of some small organisms like Bacteria. During process of cellular respiration in bacteria, glucose is broken down with the help of oxygen into water and Carbon di oxide. In the process of cellular respiration, bacteria just like humans goes through three stepsi.e Glycolysis, Kreb cycle and Electron transport chain that ultimately lead to the production of ATP (energy).

Hope it helps!

What are the nator new substances (molecules) in a chemical equation called?
mylen [45]

Answer:

A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
