fossils are the right answer
The fossils helps to examine the mineralized bones, footprints, or organisms trapped in amber in order to determine common ancestry.
What are fossils?They are the remains or traces of ancient life, which have got preserved by natural phenomenon. It can be tiny sea shells to spectacular skeletons, tracks, imprints, and trails can also become fossilized like worm burrows or dinosaur footprints.
By examining the traces and remains of life one can learn a lot about the animals and plants that lived millions of years ago and their ancestry. The study of the history of life on the planet as based on fossils is known as paleontology.
Thus, the correct answer is fossils.

why blood flow in a leg vein is slow when there is lack of movement?
Answer:
Lack of movement allows blood to circulate in a vein very slowly by sitting still for long periods of time. Slow-flowing blood is more likely to clot than normal-flowing blood. This issue is referred to as deep vein thrombosis (DVT). In DVT, as seen in the diagram, the clot normally takes place in a leg vein.
Explanation:
Lack of movement by still for long periods of time makes blood flow very slowly in a vein it is because the blood that flows slowly is more likely to clot than blood that flows normally.
What are the veins called in the leg?Large leg veins are saphenous veins. The leg veins that become weak in the most people age are the superficial veins and perforator veins.
The superficial and undesirable visible branches are known as varicose, reticular, and spider veins.
When sitting still, the flow of blood flow becomes slow, it is caused because the blood that flows slowly is more likely to clot than blood that flows normally.
This condition is called deep vein thrombosis.
Thus, due to this condition, blood flow in a leg vein is slow when there is lack of movement.

a strand of dna contains 10% adenine. what percentage of cytosine must be present in this strand of dna then?
a) 80%
b) 40%
c) 10%
d) 20%
Answer:
[tex]\boxed {\boxed {\sf B. \ 40 \% \ cytosine}}[/tex]
Explanation:
First, recall the base pairs in DNA:
Adenine and Thymine Cytosine and GuanineWe know this strand of DNA has 10% adenine. Since A and T pair, there must also be 10% guanine.
So, A and T make up 20% of the DNA strand.
That leaves 80% for cytosine and guanine. They are pairs, so they share this percentage equally.
80/2 =40There must be 40% cytosine and 40% guanine.
The strand of DNA has 40% cytosine

Is energy required for substances to pass in or
out of the cell?
Which of the methods of transport into or out of
the cell require energy?
Which do not?
What's the function of the cell membrane?
Answer:
energy can be needed for both passing in the cell or out of the cell, it depends on the type of transport. there is active transport and passive transport. passive transport does not require energy while active transport does. the function of the cell membrane is to act as a gateway for materials to go in and out and to choose what goes in and what doesn't and what leaves and what doesn't.

7. a) How does adaptation affect the diversity of a species?
Answer:
Adaptations generally occur in order to increase the fitness and thus survival of organisms. By being able to adapt to the changing environment, organisms are better able to survive and reproduce.
Explanation:

4. Genes that are responsible for new characteristics that help a species survive in a particular environment
are most likely to do which of the following?
A. rapidly decrease in frequency
B. gradually decrease in frequency
C. increase in frequency
D. not change in frequency
Answer:
The correct answer is - increase in frequency.
Explanation:
According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.
According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.

2 examples of transfer by contact, induction, and conduction
Answer: The two examples of conduction and induction are as follows.
Explanation:
Conduction can be defined as the process of transfer of charges from the charged body to the neutral body by direct contact whereas the induction is a process in which the charges are induced in the neutral body by the charge body. The conduction process requires the direct contact between the bodies in which the charges are being transmitted.
The example of the conduction process involves the neutral metal sphere gets charged when comes in contact of aluminum plate that exhibit a charge.
The example of induction is the rubbing of the rubber balloon with that of the animal fur then the two balloons will move away due to like charge repel each other.
