<span>Succession is described as the orderly, natural changes, and species replacements which occurs in communities of an ecosystem over time. Succession can be primary, secondary.
</span>Ecological succession on the other hand is an occurrence when an ecosystem becomes unstable; It is a slow and natural change in an ecosystem over hundreds or thousands of years. During ecological succession, growth of young hardwoods affect the organisms living in an ecosystem by outgrowing them because there was an increase in shading by the fully grown hardwoods. For instance, the sun loving pines are outgrown because the forest floors are shaded.
The Pentose Phosphate Pathway is an example of <u>anabolism</u>.
Explanation:
The pentose phosphate pathway (PPP))is more anabolic as it synthesizes complex molecules like reducing agents (NADPH) and pentose sugar from simpler glucose molecules.
The main functions of this pathway are:
Generation of reducing equivalents like reduced nicotinamide adenine dinucleotide phosphate (NADPH) (reduced form of NADP) is used for cellular anabolic reduction reactions of biosynthesis of nucleic acids, fatty acids. The PPP metabolic pathway accounts for about 60% of NADPH synthesis. NADPH functions both as a co-factor and as a fundamental metabolite in cellular biosynthesis.
The pentose sugar or the five-carbon link sugar ribose-5-phosphate (R5P) synthesized in PPP is used for biosynthesis of nucleic acids and nucleotides.
Since the products of phosphate pentose pathway are primarily used for anabolic reactions in biosynthesis, this is more anabolic.
Answer:
The best explanation for a partial solar eclipse is that moon only partially covers the sun during the eclipse (option D).
Explanation:
A solar eclipse occurs when the<u> moon stands between the sun and the earth</u>, which happens when the moon is near the plane of the ecliptic, that is, the point where the orbits of the earth and the sun intersect.
A partial solar eclipse occurs when the moon partially covers the sun, which depends on the observer's point of view on the earth and his geographical location.
The other options are not correct because:
<em> A. If the earth stands between the sun and the moon, </em><em><u>lunar eclipses </u></em><em>occur.
</em>
<em> B and C. During a solar eclipse it is not possible to see</em><em><u> lunar phases</u></em><em>, which occur when the sun's rays are reflected off the satellite.</em>
Answer:
AB type blood consists of RCB's having both 'a' and 'b' type antigens on their surface. Thus any possibility of cross reaction with any other similar peptide and generation of anti-A and anti-B is not possible, because self antigens do not elicit immune response and do not produce any antibody specific to them.
