A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.

Which of the following actions would help the skater reach the top of the other side of the half pipe?


Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.


Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.


Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.


Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.

Answers

The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.

The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.

The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.

As the heat energy is lost to the surrounding environment, the skateboard loses velocity.

Bending down by the skateboarder will provide additional energy to make up for the lost energy.

Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.

A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?

A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.

B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.

C.
The mutation is an insertion which causes an increase in the genetic variation of a population.

D.
The mutation is a substitution which causes an increase in genetic variation of a population.

Answers

The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.

MUTATION:

Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs.

A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence.

In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation.

However, this mutation will cause an increase in the genetic variation i.e. difference in a population.

The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.

Hope it helps you... pls mark brainliest if it helped you

Answer:

The nerve(s) in your leg.

Explanation:

It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.
