The answer is; C
Most often some ancestral characters are preserved in an organism's development hence can be used to study evolutionary relationships. One of these features is the gill slits in embryos. These have been used to postulate that all land organisms, that exhibit gill slits in their embryonic development, emanated from a common fish ancestor. In humans, these gill slits later develop in the pharyngeal.
Ans.
Chlorophyll b is a green colored, accessory photosynthetic pigment that helps in the process of photosynthesis by collecting enegry. It traps solar energy and transfers it to the chlorophyll a.
Chlorophyll b absorbs red and blue light of electromagnetic spectrum, which ranges from 650-680 and 450-480 nano meter. The light primarily absorbed by the chlorophyll b is blue light.
Thus, the correct answer is 'blue light.'

Answer:
Hydrophobic molecules don't like water,just like the membrane.Since the membrane and these signaling molecules are made of the same thing,liquid,they can easily mix together.
Explanation:
Hydrophobic signalling molecules move right through the cell membrane to the target inside the cell.
