Answer:
10 cm
Explanation:
water depth had the biggest difference in survival rates for embryos with UV-B protection versus embryos without UV-B protection is 10 cm . the bar graph attached in the shows that the lengths of yellow and brown bars differ the most at 10 cm.
Hence,The biggest difference between the survival rates of UV-B protected and unprotected can be seen at the depth of 10 cm.

In the formation of flat bones such as the skull the mandibles and the clavicles
Answer:
Explanation:
Let the volume of air be V. at atmospheric pressure, that is 10⁵ Pa
At 20 m below surface pressure will be
atmospheric pressure + hdg
10⁵ + 20 x 9.8 x 1000 = 2.96 x 10⁵Pa
At this pressure volume V becomes V/ 2.96
This volume will last 1/2.96 times time that is 60/2.96 = 20.27 minutes.
Positive charge=proton
Negative charge=electron
No charge/neutral=neutron
