Answer: B.  Wave A is louder than Wave B.

Explanation: The loudness of sound is measured in unit called decibels (dB).

A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.

Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.

Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.

In certain classes of antibody, the monomeric versions join to form dimers. what portions of the molecules adhere to each other
TiliK225 [7]
There are five classes of antibody.
1) <span>IgA (immunoglobin A)
2) IgD (immunoglobin D)
3) IgE (immunoglobin E)
4) IgG (immunoglobin G)
<span>5) IgM (immunoglobin M)

They form Y shaped antibodies. The crystallized fragment is the stalk of the Y shaped antibodies. The bond formed by this stalk will determine the form of the antibody. One Y is called monomer, two connected Ys are called dimers, and 5 connected Ys are called pentamers.</span></span>

Which part of photosynthesis is represented by the diagram to the right
Yanka [14]

Answer:

<em>Light-dependent reactions</em>

<em></em>

Explanation:

Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.

The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).

Why are scientific theories changed but never thrown away?
faltersainse [42]
They are like that because they can't always be faulty and may have at least some spark of truth to this theory also as stated earlier a theory in scientific terms is just an observation so it can't really be turned down hence theory.
