<u>Answer:</u>
The correct answer option is B. Green wavelengths are the least used in photosynthesis.
<u>Explanation:</u>
Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.
From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.
Therefore, this reflection of green light makes the leaves to appear green.
Answer:
When it needs water it will release oxygen into the atmosphere. That makes more room for water and it can suck it up.
Explanation:
Answer:
If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.
Explanation:
A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other
.
The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.
- <em>Adenine is combined with Thymine A=T
</em>
- <em>Cytosine is complemented with Guanina C≡G
</em>
In this way, given a sequence on a DNA strand
:
<em> T-T-C-C-G-G-A-A</em>
The complementary strand will have this sequence:
<em> A-A-G-G-C-C-T-T</em>
Answer:
Proximal tubules.
Explanation:
The proximal tubules make up a significant portion of the kidneys and they are also the site of<em> active solute secretion, hormone production, and many of the metabolic functions of the kidney</em>. This segment of the nephron in kidney has two main functions: absortion and secretion. <em>A hundread percent of organic solutes, such as glucose and amino acids are reabsorbed</em><em>, that's why they should not be present in his urine.</em>
