Select all that apply.Which characteristics are common to both birds and reptiles?
scales
ectothermic
amniotic eggs
beaks
feathers
hollow bones

Answers

Answer 1

Answer: The answer is scales and amniotic eggs.

It is obvious that reptiles have scales, which are very important for their survival. But birds have scales, too. Their claws, feet, legs and beaks are covered by scales.
Reptiles and birds, together with mammals, belong to the group of Amniote, which means their eggs are amniotic. Amniotic eggs are either laid on land or retained inside the mother, unlike anamniotic eggs that are laid in the water.

Some of the listed characteristics are not common to both groups:
- Only reptiles are ectothermic (cold-blooded animals) while birds are endothermic (warm-blooded animals).
- Birds have beaks and reptiles have teeth.
- Birds are the only animals with feathers.
- Birds have hollow bones, and thus, lighter which help them to fly. Reptiles bones are dense and heavy.

Answer 2

Answer:

Answer:

Scales

Amniotic eggs

Beaks

Explanation:

According to the reading,

"Birds are said to have evolved from the Reptilia. They do have some similar features. They have scales on their legs and feet; they lay amniotic eggs, but with a hard shell; they have beaks, similar to many reptiles, particularly turtles."

Which of the following factors does not favor a change in gene frequency and, therefore, evolution?(A) large populations
(B) mutations
(C) emigration
(D) genetic drift
(E) all of the above
Can anyone explain this one?

Answers

Genetic drift does not favour a change as it is all about the variation of genes within a SMALL population; smaller population = smaller variation of genes

All the rest do favour a change in gene frequency

Cold-blooded animals use photosynthesis to convert sunlight into energy for cell functions.
Green plants use photosynthesis to ...

Answers

Photosynthesis is carried out in the chloroplasts which contain the green pigment chlorophyll. Chlorophyll is what gives plants their characteristic color and it works by capturing the energy that is in the sunlight that strikes the plant. Photosynthesis is important to life on Earth because grass uses photosnthesis to produce glucose, which is used within the grass for growth. Subsequently, organisms that consume the grass obtain energy and so on. Therefore, photosynthesis is the process through which energy enters an ecosystem.

the answer is chlorophyll
