Answer:

jayfeather friend me

Explanation:

Answer: The mechanical advantage of a machine is 4. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.

Answers

Answer:I feel like some of the answers for me would be A and B but if you only had to choose one I would choose A

Explanation: When you buy recycled you are helping the local economy and the environment. You already know that recycling keeps useful materials from going to waste in landfills or incinerators. But did you know that buying recycled-content products ensures that markets for those recovered materials are strong

Edit: Just figured out it's not B here's why:

Plastics marketed as "biodegradable" will contribute to plastic pollution if they are lost or littered. They do not break down as quickly and completely in the environment as the term might imply and thus can harm wildlife and ecosystems. Sorry if it's long

At the time when the consumers do to make sure that more materials are recycled so here option A is considered i.e. buy products made from recycled materials.

Recycled materials:

At the time when we purchase the recycled so you helped the economy as well as the environment. Also, recycling plays a vital role for minimizing the wastage and make the proper utilization of the product.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?

Answers

Answer:

Option D

Explanation:

The complete question is

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?

a) Energy was destroyed during certain steps in the experiment.

b) The steps in the experiment required more energy than was available

c) The experiments created energy that was then used up at a faster rate.

d) Some energy was transformed into unwanted heat or sound that was not detected

Solution -

Option D is correct

While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.

Is energy recycled?

How is the age of the earth used as evidence of evolution?

Answers

Answer:

Explanation:

All radiometric evidence points to the age of the Earth as about 4.54 billion years old. The old age of the Earth is evidence for evolution, a change in the genetic makeup of a population over time.

Answer:

The age of the earth can be used as evidence of evolution because it withholds the past that we are capable of uncovering bit by bit. We excavate fossils buried in the ground which we use accordingly. The fossil record reveals that the deeper you go, the farther back in history you unearth. This is known as the Law of Superposition. With these fossils, we can compare and contrast the anatomy of closely related organisms and possibly uncover vestigial structures. All of which is evidence that evolution has taken place.

Which of the following statements explains the importance of enzymes that check for and repair mistakes during DNA replication?

A
The enzymes replace the DNA with RNA
B
The enzymes speed up the rate of RNA synthesis.
C
The enzymes prevent many genetic mutations from being expressed
D
The enzymes remove many recessive gene copies from the nucleus.

Answers

Answer:

C!!

Explanation:

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

What is RNA polymerase?

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
