What is chemiosmosis?

Biology
1 answer:
Arada [10]3 years ago
6 0

Answer:

Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An example of this would be the formation of adenosine triphosphate by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis.

kow [346]

Answer:

B. He believed that sexuality is a continuum and wanted to classify people more precisely

Explanation:

Kinsey quantified in his studies heterosexuality and homosexuality on a continuous scale from 0 to 6, specified in heterosexual and homosexual experience and reactivity in each story. 0 on this scale is assigned to individuals with exclusively heterosexual sexual contacts and experiences and 6 to exclusively homosexual individuals.

He proposed a model according to which there are many intermediate degrees between heterosexuality and homosexuality. This gradualness was embodied in what is now known as the Kinsey scale.

when Na lost e it shrank and the CI+ grew in size does that say anything about the location of the electrons before and after it
ValentinkaMS [17]

<span>We know that electrons are occupied on a cloud surrounding the nucleus. So which means that the bigger the electron cloud, the bigger the number of electrons. So in this case, since Na shrank so it lost some electrons. And since Cl+ grew in size of the electron cloud so electron was added to it.</span>

When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference
REY [17]

Answer:

The best answer to the question: What is the most likely explanation for this observation, would be, B: RNA processing removes the different segments from the mRNA molecules of each person prior to translation.

Explanation:

In order for cells to work, they depend on one of the four major macromolecules; proteins. These proteins are the messengers that carry out genetic commands from the DNA and they will ensure that all processes, including transcription and translation of new proteins, are carried out correctly. In order to produce proteins, the first step is for the DNA to be transcribed into mRNA, a nucleic acid that carries out the information on the DNA for protein generation. Once transcription stops, mRNA undergoes a series of clipping and reorganizing steps that will ensure that when it is decoded for protein formation, the process will be successful. These control steps are all part of the RNA processing mechanism that enures mRNA will successfully be translated into working proteins.

The reason why from genes of different people, a very similiar protein chain may result, is also explained from the fact that codons (a grouping of three nucleotides present in mRNA), when read by ribosomes, and coupled by tRNA, can pair these codons with similar amino acids. Thus, one codon, or similar codons, may code for a singular amino acid. However, mechanisms in the cells prevent these kinds of anomalies, by repairing the mRNA sequence before it is translated into protein.
