Completed part of the questionErrors in copying can result in changes in the DNA sequence that could be inherited by future generation.
Answer:
DNA stores genetic information in the sequence of its bases
DNA can be replicated by making complementary copies of each strand
Errors in copying can result in changes in the DNA sequence that could be inherited by future generation.
Explanation:
<u>the fact that DNA is located in the Nucleus is not related to double strands.</u>
<u>the DNA csn change is not relevant ,</u>
<u> therefore the above 3 options are the correct answers.</u>
Answer:
active transport, like Na + ions leaving the cell
Explanation:
The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.
Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.
The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.
The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.
An action potential involves the transfer SODIUM and POTASSIUM ions across an axon's membrane.
During depolarization, when the ion channels open, they allow the influx of sodium ions into the cell, thus changing the electro-chemical gradient of the cell, in order to counter balance this, potassium ions will be allowed to flow out of the cell.<span />
