Snakes and lizards are reptiles. both organisms have pelvic organs, even though snakes don’t have hind legs. what are the best explanations for this situation?
select all the correct answers
a. snakes evolved from lizards, and the hind legs are vestigial in nature.
b. snakes and lizards share a common ancestor.
c. snakes and lizards belong to same species.
d. lizards evolved from snakes, which lost their hind legs during evolution.
e. lizards and snakes don’t share a common ancestor.

Option B, Snakes and lizards share a common ancestor.

Explanation:

From the description provided, it is clear that both the lizard and snake (including pythons) have evolved from the same ancestors which had hind legs. Since both the organism (i.e lizard and snake) underwent evolution (differently) for million of years such that the hind legs in lizard are visible and used even today but the hind legs in snakes are buried in  muscles toward their tail ends and are not used. Such features which are not used at all or are poorly used are called as vestigial organs.

Hence, option B is correct

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
