Answer: No, only identical twins will look identical.
Explanation:
Identical twins are also called monozygotic twins. Such twins are produced by the fertilization of one egg that splits into two. The genes present in these twins are same thus the expression of traits is also same in them and they have the same sex.
Sam and Joe and Maria and Ella are identical twins these pairs are expected to have same genotypic and phenotypic traits. They may be clones of each other. But if Sam and Maria are married and Joe and Ella are also married then their children will have some similar traits in common but their children will not be identical as they are not identical twins as their parents were.

Explanation:
Answer:
The correct answer is 88.84 mmHg.
Explanation:
The pressure differential between the brain and the heart while standing up will be 120 - rho × g (gravity) × h, here h is the distance from the brain to the heart. The h is 40 cm or 0.4 m.
rho×g×h = 1060 kg/m³×9.8 m/s²×0.4m
= 4155 Pa
Now converting Pa to mmHg we get:
4155 Pa × 760 mmHg / 1.01325 × 10⁵ Pa
= 31.16 mmHg
Thus, the pressure in the brain now is 120 - 31.16
= 88.84 mmHg (hypotension)
Its chlorophyll pigment would be adapted to utilizing the blude-green spectrum of sunlight for photosynthesis rather than the red spectrum like land plants. This is because red light is absorbed by the oceans and does not reach greater depths (this is why oceans appear blue). These plants would therefore appear red in color.
Plants that live in the oceans have air-spaces in their leaves that that help them stand upright in water. They use buoyancy for structural integrity. This is why even long plants such as kelp seem to be upright in water (but will collapse when put on land).
