Hi btw
This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.
<h3>What is a food chain?</h3>
Food chain is the sequence of matter and energy transfers as food from one organism to another.
Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.
The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.
Thus, it can be concluded that this is the main reason behind the number of snakes consumed as compared to other organisms.

Answer:
The egg contains both food and mitochondria in addition to its vital DNA, thats why it is much larger. The sperm cell has to be much smaller than the egg cell, because it is the one that swims. If a sperm cell were as big as an egg, it would not be able to move very fast nor very far.
