Answer:
Focal length of the lens increases hence the size of the lens increases.
3)B
4) B
Explanation:
3)Focal length of the lens increases hence the size of the lens increases.
Pupil of the eye decreases in size so as to decrease the amount of sunlight entering the eye when the person looks at the sky. As the size of the pupil was increased for increase the intake of the light while reading a book in the shade
4) Im not really sure, but i am pretty sure it's B. Don't take my word ;D
Hope this helps,
Best of Luck
Answer: Phosphorylation of mitotic sites at the start of mitosis (N-terminal S22 and C-terminal S392 in human lamin A/C)
Explanation: During mitosis the nuclear lamina is dissociated by phosphorylation- dependent mechanisms that causes conformational changes in structure at N- and C-terminals (non alpha helical terminals) during the start of cellular mitosis that leads to its disassembly. This is because the nuclear lamina has two sites that accept phosphates (phosphoacceptor sites) causing a phosphorylation reaction.
The nuclear lamina is a fibrillar network of intermediate filaments as well as membrane proteins and are involved in DNA replication, cellular division as well as providing mechanical support within the cell.
Answer:
d) It binds to intracellular receptor.
Explanation:
Nitric oxide is a compound produced by many cells of the body. It relaxes vascular smooth muscle by binding to the heme moiety of cytosolic guanylate cyclase(intracellular receptor) ,activating guanylate cyclase and increasing intracellular levels of cyclic-guanosine 3',5'-monophosphate, which then leads to vasodilation.
B evaporation because the partacals r moveing
