What is the name of the gradient between high pressure and low pressure?
Answer:
Pressure gradient
Explanation:
Hope this helps :)
Answer:
Pressure gradient
Explanation:
The change in pressure measured across a given distance is called a "pressure gradient". The pressure gradient results in a net force that is directed from high to low pressure and this force is called the "pressure gradient force". The pressure gradient force is responsible for triggering the initial movement of air

Only one plane divides the bodies of humans, dogs, and rabbits into roughly symmetrical "left" and "right" halves.
What type of symmetry do these organisms have?
A.
orbital
B.
bilateral
C.
radial
D.
rotational
Answer: Bilateral
Explanation:
symmetry is a type of symmetry in which only one plane divides an organism into halves that are roughly mirror images of each other. The halves need to be mirror images only on the exterior.
If more than one plane of symmetry exists for an organism's body, then it is radially symmetric.

What are ocean waves caused by? What affects how large they are?
Answer:
Waves are most commonly caused by wind.The size of a wave depends on three factors: the distance over which the wind blows across open water, the strength of the wind, and the duration that the wind blows. The larger these factors, the larger are the waves.

A.The metal will melt and the food will burn.
B.The metal insulates the food from the heat.
C.The metal reduces the heat until the food freezes.
B.The metal will heat well so the food will cook evenly.
2. The mutation below is best described as a
A.nonsense mutation.
B.missense mutation.
C.frameshift mutation.
D.point mutation.
Answer:
Frameshift mutation
Explanation:
The first nucleotide is removed or deleted but it's not up to three so it can't code for any amino acid.
The coding shifts from one point to the next.
Which nitrogenous base would pair with adenine during DNA replication?
A
O cytosine
<
B
O guanine
C
Othymine
D
ouracil
The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.
What are nitrogenous base?
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules and adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G). 18% became cytosine pairs with G. A pairs with T. T and C are not complementary base pairs, but we know that if molecules consists of 32% T, it must have 32%.
The discovery of the structure of DNA was useful because it revealed how mRNA was used to make proteins. There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
HDL stands for high-density lipoprotein or good cholesterol which absord cholesterol and send it to lever. The lever then flushes it from the body. High-density lipoprotein can lower your risk for heart disease and stroke.
Therefore, The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.
