Answer:
Option-C
Explanation:
Scientists found a fossil of a fish with four limbs or legs. The fossil was estimated to be around 375 million years old.
The fossil showed the fins and scales of a fish but they also possess the bones of proto-wrist, shoulders and the elbow.
The presence of these bones can be a clue that the fish evolved the limbs to walk on the land and will later evolve into animals belonging to amphibians, reptiles and mammals. Therefore, the Tiktaalik is considered the missing link of how life evolved from water to land.
Thus, Option-C is correct.

Answer: The size.
Explanation: On the one hand the Emperor Penguin is bigger reaching up to 48 Inches (120cm) of height and 100 Lb in weight, on the other hand the Galápagos Penguin is much smaller. For example a large adult usually goes up to 21 Inches (53cm) and 5 Lb of weight.
This is directly related to the temperature of the environment in which each one develops, because a body exchanges heat in two dimensions through the surface. So, it's easier for a big creature to maintain core temperature stable.
This is really important in environments like the Arctic where temperature goes below zero and the opposite happen in the Equator where there is a tropical weather all the time.
Answer:
In the dark phase (which takes place in the stroma), the ribulose bisphosphate added to the carbon dioxide gas (CO2) in the air results in the production of organic compounds, principally carbohydrates or sugars, whose molecules contain carbon, hydrogen, and oxygen.
Explanation:
Answer: There will be one homozygous straight wing, two heterozygous straight wings, and one homozygous curly wing.
Explanation: A true breeding pair means that both parents are heterozygous (Ww). Set up a Punnett square with two Ww parents. The offspring will be 1 WW (homozygous straight), 2 Ww (heterozygous straight), and 1 ww (homozygous curly).
