I looked up the definition of transmitted and it fits better

DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The correct answer is option C.

What is the role of mRNA ?

mRNA is the code of DNA that carries the information of coding proteins from the nucleus to the cytoplasm.

DNA is transcribed into mRNA where it is transcribed intro message to which kind of protein is about to be formed. A triplet forms one amino acid and this process is taking place in the ribosome.

The chain of amino acids forming a protein is released in the cytoplasm and the proteins is then assigned a particular position where so ever is them needed mostly in the cytoplasm.

Therefore, DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The activity takes place in the ribosome.

I am able to fill a glass of water to the top and it does not overflow…which property of water allows this to happen

Answers

Answer: surface tension

Explanation:

Answer:

When we fill the glass with water, we notice right away that it can go over the brim of the glass without spilling. This is because of surface tension. Surface tension holds the water together and acts against what would normally cause the water to fall – gravity – because each molecule of water is attracted to the other water molecules around it.

Explanation:

extra facts Water molecules are attracted to each other and is why you can fill a glass and as it gets to the top it will stay together to a certain point. However that stick together ability is pretty mild so when gravitational forces take effect the bonds are broken and it flows down the sides of the glass. Unfortunately, the attraction between the water molecules is only so strong. As we add coins, the amount of water spilling over the edges is getting larger and larger until the water just can’t take it anymore! Gravity is pulling on too many of the molecules for their attraction to keep them up, and the water spills down the side of the glass.What to Do. Place the glass on the saucer and fill the glass of water all the way to the brim. You’ll notice that the water hangs slightly over the top of the glass but doesn’t spill out just yet. Now, add the coins one at a time to the glass of water, dropping them in rim-first (not face down).

Metamorphic rocks are common when two continental plates collide because There is a lot of stress when enormous slabs of crust push together Sediment buries rocks to increase pressure O Magma bodies are common because there is a lot of melting O All of these​

Answers

Answer: Metamorphic rock, estimated to be as old as 3.8 billion years, located near Isua at Qorqut Sound, Greenland.In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Sedimentary and igneous rocks began as something other than rock. Sedimentary rocks were originally sediments, which were compacted under high pressure. Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened. A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock.

The conditions required to form a metamorphic rock are very specific. The existing rock must be exposed to high heat, high pressure, or to a hot, mineral-rich fluid. Usually, all three of these circumstances are met. These conditions are most often found either deep in Earth’s crust or at plate boundaries where tectonic plates collide. In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock.

triggering of the muscle action potential occurs after

Answers

Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.

An action potential is an electrical signal that travels along the cell membrane as a wave.

This action potential (muscle action potential) drives the contraction of muscle fibers.

When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.

Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.

what is the effect of water temperature on corals from inshore and offshore reefs?

Answers

Answer:

When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.

Explanation:

When the water temperature rises too high, algae can no longer live inside corals and leave. Coral bleaching occurs when the corals turn from green to white.

What are coral reefs?

A coral reef is an underwater ecosystem characterized by corals that build reefs. Reefs are made up of coral polyp territories hosted along by calcium carbonate.

The vast bulk of coral reefs are mainly composed of stony corals, which have polyps that coalesce together.

Coral reefs grow in shallow water with temperatures ranging from 68° F to 97° F. The Indo-West Pacific biogeographic region contains more than 90% of the world's coral reefs.

When the temperature of the water rises too high, algae can no longer live inside corals and must leave. Coral bleaching occurs when corals alter color from green to white.

The Earth's air and oceans are becoming warmer as a result of climate change. Coral bleaching is becoming more common as the oceans warm.

Thus, this is the effect of water temperature on corals from inshore and offshore reefs.
