Answer:
Global warming is making the sea more salty, according to new research that demonstrates the massive shifts in natural systems triggered by climate change. Using state-of-the-art climate models, the scientists simulated events over both parts of the ocean with and without increased levels of greenhouse
The given observation in sea urchins implies that new proteins should be synthesized so that the process of cell division can take place.
Sea urchins belong to the phylum Echinodermata. These organisms are mostly preferred by the embryologists for studying the process of cell division because they produce gametes in abundant amount which can be obtained easily. The sea urchins produce eggs as well as embryos which are transparent in nature.
Early cell divisions in sea urchins are fast-paced. Radial holoblastic cleavage can be observed in sea urchins. The proteins that are manufactured during cleavage use mRNAs present in the cytoplasm given by the female parent.

Explanation:
Answer:
Cells of skin, for instance, have highest mitotic index.
Explanation:
Many cells are capable of dividing rapidly. <u>For example</u>, in plants, the cells near the root tip in the apical meristem divide rapidly to push through the soil because the root cap detects the gravity and direct rapid division and growth of cells near the tip.
If we take muscle, skin, kidney, and lung as examples that are given in real question, <u>skin cells have the highest mitotic index because they need to get replaced most frequently</u>.
