Answer:
help you with what theres no question here??
Explanation:
Explanation:
s waves are shear waves. they move by material flexing or deformity sideways from the direction of waves travel
Crossing over at prophase I results in the linked genes (those on the same chromosome) becoming unlinked and separated. Prophase I is this first stage of meiosis, the chromosomes condense, form tetrads, and exchange DNA. The nucleolus and nuclear envelope disappear.
Yes accumulation of mutation can drive aging process.
Explanation:
The molecular damage that occurs in cells and tissues for a long time due to DNA damage and epigenetic changes gets accumulated in the cell.
This leads to lowering of the homeostasis in the cell during stress conditions and eventually risks of life-threatening diseases as cancers or neurodegenerative disorders develop.
Due to mutation in the gene DNA repair mechanism also gets affected this also contributes to the ageing of cells.
The telomere of the chromosome is shortened after every mitotic division but telomerase enzyme keeps adding the DNA sequence preventing shortening aging and death of the cell. If the mutation occurs in this enzyme it will increase the ageing of cells at high rate.
Note: Question is incomplete i have added full question in ask for detail section.
Answer:
Option a) Velocity increases.
Explanation:
When liquid flow from wider vessel to narrow it follow bernoulli's law. It means the velocity will increase. I have attached picture for better understanding.
