What is the primary goal of Earth system science?

1 answer:

5 0

To understand how Earth’s subsystems interact and affect one another is the primary goal of Earth system science. Thus, the correct option is D.

What is Earth made of, explain?

The composition of the Earth is diverse. The Earth's core, which is primarily composed of nickel and iron, is located close to the planet's center deep within. The rock that makes up the Earth's mantle, which is located above the core, contains minerals such as silicon, iron, magnesium, aluminum, and oxygen.

Understanding how the Earth is changing and the effects on life on Earth is the goal of Earth System Science, with a focus on enabling prediction and mitigating unfavorable outcomes.

Ipatiy [6.2K]

Answer: 1, 3, 5, 2, 6, 4

Explanation:

The sympathetic nervous system stimulates many parts of the body for action during times of danger.

This signalling starts when the postganglionic neuron depolarizes, and postganglionic neuron releases acetylcholine, then the acetylcholine binds to nicotinic receptor in order to transmit impulse, and further the acetylcholine binds to sweat gland’s muscarinic receptor to disrupt or inactivate the action of acetylcholine. Finally, the neuron releases acetylcholine, and the neuron exits lumbar segment of spinal cord.

The danger has now been fully interpreted.

Why can't both strands of DNA be replicated at the same time?

saw5 [17]

Answer: DNA is a molecule made up of two strands, twisted around each other in a double helix shape. The two strands are complementary which have a 5 prime end and a 3 prime end. To understand this question you must first understand the steps that follow.

DNA Replication:

Step one: 

DNA Helicase (unzips) separates the strands.

Step two:

DNA Primase starts the process and makes a small piece of RNA called a primer. This marks the starting point for the DNA.

Step three:

DNA Polymerase binds to the primer and will make the new strand of DNA. DNA Polymerase can only add DNA bases in one direction, from the 5 prime end to the 3 prime end.

The leading strand is made continuously.
The lagging strand does not run continuously because it runs in the opposite direction. Each fragment is started with an RNA primer. DNA Polymerase then adds a short row of DNA bases from the 5 prime to 3 prime direction. This results in okazaki fragments because it can only replicate in small chunks. The process is repeated.

Step four:

Once the new DNA is complete the enzyme exonuclease removes all the RNA primers from both strands of DNA.

Step five:

Another DNA Polymerase fills in the gaps that are left behind with DNA.

Step six:

DNA Ligase seals up the fragments in DNA, in both strands to make a continuous double strand.

Final answer:

DNA Replication cannot replicate at the same time due to the leading and lagging strand.

Good luck!
