Because it’s in smaller price so therefore can’t melt faster than the block, since the smaller peices will melt at the same time as one another.
Plasma membrane. controls in/out of cell.
chromosomes. DNA, instructions for protein synthesis.
ribosomes. manufacture proteins.
metabolic enzymes. building and breaking down molecules.
cytoskeleton. skeleton of cell that proteins can move by.
For the answer to the question above, I believe the answer to the question is that <span>the steroid receptor protein cannot enter the nucleus so the gene of interest is repressed even in the presence of the hormone. I hope this helps</span>
²²⁷₉₀ Th is the daughter nucleus (nuclide) produced when ac227 undergoes beta decay by emitting an electron.
A fast energetic electron or positron called a beta particle is released from an atomic nucleus during beta decay, which changes the original nuclide into an isobar of that nuclide. When a nucleus has too many protons or neutrons, beta decay happens when one of the protons or neutrons is converted into the other. A neutron decays into a proton, an electron, and an antineutrino in beta minus decay: n p + e - +.
During beta decay, an unstable nucleus undergoes the conversion of a neutron into a proton, so
¹₀ n ----> ₁¹p + ₋₁⁰e ( Z + 1 )
The complete reaction is as follows:
²²⁷₈₉AC -----> ²²⁷₉₀ Th + ₋₁⁰e
Therefore, the daughter nucleus is ²²⁷₉₀ Th.

Answer:
Option 4, they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands
Explanation:
Thymine dimer is formed on adjacent thymine and hence they lie next to each other on the same strand. They do not lie on strand that are opposite of each other on different DNA strand.
Hence, option 4 is correct
