Yanni made a chart to compare the strong and weak forces. Which best describes Yanni’s error? Only the weak force is active in t
cluponka [151]

Answer: Option (d) is the correct answer.

Explanation:

Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.

But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.

This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.

Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.

Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.

Explain why each chromosome must become two strands before the cell divides.​
sp2606 [1]

Answer:

To allow transcription enzymes to access the DNA strand

Explanation:

The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.

DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.
