Answer: 10 cm

Explanation:

The water at 10 cm has the biggest survival rate for the embryos with ultraviolet B protection as compared to that of embryo which are not protected by UV-B.

Ultraviolet rays can be very harmful as it can reach the fetus but due to some particles present in water the intensity of UV-B becomes attenuated below 10 cm of water.

So, the correct answer is 10 cm.

kkurt [141]

Answer:

The correct answer is - tight junctions.

Explanation:

Tight junctions are one of the cell-cell junctions that make a barrier to the passage of material which is a present in epithelia. This barrier is impermeable to most of the materials with soluble molecules. This barrier is made up of the occludin and claudin proteins.

Tight epithelia have tight junctions and examples of such junctions are the distal convoluted tubule or DCT, and the collecting duct of the nephron in the kidney.

Thus, the correct answer is - tight junctions.
