Answer:

Some of the associations point towards the fact that water is a more substantial contributor to atmospheric warming. Thus, they are against the fact that carbon dioxide is a significant greenhouse gas, therefore, any witnessed warming is not the outcome of human activity. According to many of these organizations, the discussion of climate change or global warming is a form of alarmism made by the media.

Answer:

The inactivation of one protein that slow down the cell cycle could lead to cancer. (option b).

Explanation:

The cell cycle is the process a cell undergoes when it divides during its life. This process includes a control mechanism to prevent normal cells from replicating more than normal, called cell cycle regulation.

In oncogenesis - the formation of malignant tumours - many factors induce the abnormal growth of a tissue by the abnormal multiplication of the cells that form it, leading to cancer. One of these factors may be a mutation in the DNA that prevents the production of regulatory proteins.

The mutation that produces exaggerated cell growth -and which can eventually lead to cancer- can create defects in a specific regulatory protein that slow down the cell cycle, so that exaggerated and uncontrolled cell replication occurs.

Once a tumor tissue has formed, successive mutations will lead to a lack of cell differentiation, the property of forming blood vessels, the ability to invade tissue and lose its apoptosis mechanism, that characterizes cancer cells.

Create a nucleotide sequence with at least 9 DNA bases. Then, replicate your DNA strand using the appropriate DNA bases.
arsen [322]

Answer and Explanation:

We need to create a nucleotide sequence, but first what are DNA nucleotides? They are the monomers of the entire nucleic acid strand of DNA.

DNA nucleotides have 4 bases: adenine (A), thymine (T), guanine (G), and cytosine (C). When pairing bases, A and T always go together and G and C always go together. (An interesting trick to remember this is Apple in the Tree and Car in the Garage.)

To create our own, we can draw up any combination of A's, T's, C's, and G's. I'm just going to arbitrarily write the following:

A A G C T T C G A T C G A C C

We need to pair these up by replicating it (remember A with T and G with C). The new strand will become:

T T C G A A G C T A G C T G G

Finally, we need to transcribe this back into the original format because replication is creating the same copy of something:

A A G C T T C G A T C G A C C

Which prediction will most likely describe how friction will affect her findings? The distance for Trial 3 will be greater than
Juliette [100K]

The complete question is :

Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.

Which prediction will most likely describe how friction will affect her findings?

Answer:

The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.

Explanation:

The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.

In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :

F' = F - f

Here, F = the force applied

         f = force of friction

And f = μ.N (N = reaction force)

Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.
