Answer: A. A scientific paper is a reliable source of information.
Explanation:
A peer review is a kind of analysis of the research outcome by the people who generally exhibit the same competency as that of the author or researcher and knowledge for a particular subject or topic in which the research has been conducted. Such a process makes the research outcome more authentic and reliable. The author learns to improvise the research process and corrects the mistakes after the peer review.
The pigment that traps energy is Chlorophyll.
Chlorophyll is a green pigment commonly found in almost all
plants, algae and cynobacteria. Leaves appear green because they contain this
pigment. This pigment absorbs the light energy from the sun to complete the
process of photosynthesis or food production of plants. Chlorophyll is said to
absorb light in the long wavelength and blue in the short wavelength regions of
the visible light spectrum. Green light is not absorbed, thus making the leaves
of some plants green. Chlorophyll is found at the plant’s chloroplasts, which
comes to have different structures.
Answer:
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
The stem of the plant should be cut at least three to four inches above the surface level.
The glass capillary should be tightly fixed with the stem.
The initial water level and the final water level should be carefully noted.
The droplets on the leaves should be observed and conclude that these drops are not from transpiration.
