Answer:

C.) lungs

Explanation:

In the cladogram, amohibians and reptiles are seperated under the 'lungs' branch.

Therefore, having lungs is a shared characteristic among amphibians and reptiles

According to the cladogram bony skeleton and lungsare the derived characteristic shared by amphibians and reptiles. Hence the correct option is C.

A bony skeleton is a derived characteristic shared by both amphibians and reptiles. Unlike more ancient organisms like cartilaginous fish, which have a skeletal structure made of cartilage, both amphibians and reptiles have evolved to possess a bony skeleton composed of hard, calcified bones. This bony framework provides greater support and protection.

Lungs are another derived characteristic shared by amphibians and reptiles. As vertebrates that have adapted to life on land, both groups require a reliable respiratory system to breathe air. Lungs are specialized respiratory organs that enable these organisms to extract oxygen from the air and release carbon dioxide.

Hence the correct option is C.

The given question is incomplete, the complete question is

Answer:

41 minutes

Explanation:

According to this question;

- Roberto spent 90 minutes doing homework

- Roberto spent 2/3 hour reading. Since 1 hour = 60 minutes

2/3 hour = 2/3 × 60 = 40 minutes.

- Roberto spent 540 seconds making his lunch for the next day. Since, 60 seconds = 1 minute

540 seconds = 540/60

= 9 minutes.

The total amount of time Roberto spent reading and making his lunch is = 40 + 9 = 49 minutes.

Therefore, the amount of time Roberto spent doing his homework than reading and making his lunch is (90 - 49) = 41 minutes.

The shape, size, daily activities, structure, and function of an organism can be determined by the fossil. Hence all options are correct.

Any surviving remains, impression, or evidence of a once-living thing from a previous geological epoch is referred to as a fossil. Examples include exoskeletons, bones, shells, animal or microbe imprints in stone, items preserved in amber, hair, petrified wood, and DNA traces. The fossil record is the collection of all fossils.

The study of ancient plants and animals that have subsequently faced extinction or have evolved into present species is made possible by the discovery of fossils.

Important evidence for evolution and the environmental adaptability of plants and animals can be found in fossils. Hence, all options are correct.

450 % change occur in the amount of runoff in urban area as compared to forest area.

450 % is the percent change in the amount of runoff in urban areas as compared to forested areas. We can see in the diagram that in forest area only 10% is runoff water while some is absorbed by the soil and other evaporated in the air.

While on the other hand, in urban area 55% of water leaves the area through runoff which is 45 % higher than forest area so when we put these values in the formula of percent change we get 450 % so we can conclude that 450 % change occur in the amount of runoff in urban area as compared to forest area.
