Answer:
Photosynthesis is a key part of the carbon and energy cycles by means of the atmosphere and the biosphere.
Answer:
<u><em>The correct option is C) genetic variation</em></u>
Explanation:
Genetic variation can be described as the differences present in the genetic material i.e DNA of organisms present in a population. Genetic diversity allows organisms of a species to better adapt to an environment. A population in which the genetic variability is scarce might become wiped out by a disease or an invading predator.
As the birds show different variations hence the term that best described them is genetic variation.
Answer:
trocophore larva
Explanation:
The trocophore larva is a marine planktonic larvae. The mollusca, annelida, and nemerteans shows trocophore as larval stage.
The trocophore larva shows similarities with invertebrates group of organisms. This similarities provide evidence that bilateral symmetry organisms evolved from radial symmetry. The larva represents a transitional stage in ctenophore emergence. There are close similarities in trocophore larva and annelid larva (echinoderm). Thus, a close evolutionary relationship between annelids and mollusks is suggested by the presence of a <u>trocophore </u>larva in both phyla as well as by molecular sequence comparisons.
Answer:
. 2C- acetyl Co-A from the link reaction enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6- Citrate
The Citrate forms intermediate Isocitrate, which eventually formed 6-C alpha ketoglutarate.
The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed 5C-succinate.
5C -Succinate forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.
The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid from which other products are formed from.
