which strand of the DNA molecule A or B was used to produce the messenger RNA?

Which Strand Of The DNA Molecule A Or B Was Used To Produce The Messenger RNA?

Answers

Answer 1

Answer:

Strand A

Explanation:

Why is it strand A when it looks exactly like strand B? During transcription, a strand of RNA is made that compliments the DNA. Meaning they don't exactly match but they're the partner nucleic acid. These are the instructions that tell what protein to make.

Answers

Answer:

The genetic variation in the population will decrease or stay the same

Explanation:

In an ecosystem , if environmental conditions forced a population of these organisms to use only asexual reproduction, the genetic variation in the population will decrease or stay the same.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

As the mass of an object increases, what happens to the gravitational force created by that object?

Answers

Answer:

the gravitational force is proportional to the mass of both interacting objects, bigger objects will attract each other with a greater gravitational force. So the mass of either object increases, the force of gravitational attraction between them also increases.

Answer:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force.So the gravitational attraction between them also increases.

When you touch the screen of a smartphone, these receptors are sending messages to the brain.
pain receptors
thermoreceptors
proprioreceptors
mechanoreceptors



EXPLAIN

Answers

The mechanoreceptors are for touch, thermoreceptors detect changes in temperature, pain receptors detect pain, this only leaves proprioreceptors, therefore, this is your answer

Answer:

Mechanoreceptors

Explanation:

If Propriorceptors are for sensing light, thermoreceptors are for decenting temperatures, and pain receptors are for detecting injury, then mechanoreceptors would be used for sensing touch, and in this case you are touching the iphone screen, so mechanoreceptors is the correct answer.
