Answer:
Radiolabeled carbon atom in CO2
Explanation:
Photosynthesis is the process by which green plants fix the atmospheric CO2 into glucose. The process includes carbon fixation during which RuBisCo enzyme catalyzes the reaction of CO2 and a five-carbon compound called RuBP to form 3-phosphoglycerate (3-PGA). The 3-PGA enters the reduction phase of the Calvin cycle wherein it is reduced into glyceraldehyde 3-phosphate. Two molecules of glyceraldehyde 3-phosphate make one molecule of glucose.
To test the hypothesis that glyceraldehyde 3-phosphate from photosynthesis is used by plants to synthesize lipids, radiolabeled CO2 must be used. The radiolabeled carbon atom in the CO2 would be fixed in the form of glyceraldehyde 3-phosphate. If the plant uses glyceraldehyde 3-phosphate as a precursor for lipid synthesis, the synthesized lipid molecules would carry the radiolabeled carbon atom.
Answer:
The evolutionary history for a group of species is called a <u>phylogeny.</u>
Explanation:
Phylogeny is defined as the evolutionary history or evolutionary chronicle of the species, that is, it studies the relationship deals with the relationship between members of a group of species from the morphological, anatomical and embryological point of view. In this way, phylogeny explains the chronicle of each species, the different bifurcations, families and genetic structures, focusing on the evolution of the species in a global way.

Answer:
Amino acids with non-polar side chains.
Explanation:
The class of proteins that is unable to form hydrogen bonds with water are the amino acids with non- polar side chains. This class includes the amino acids
Alanine
Valine
Leucine
Isoleucine
Proline
Phenylalanine
Cysteine
Methionine
Tryptophan
These are the nine proteins which are considered to be strongly hydrophobic. All these amino acids are hydrophobic in nature due to their side chains. Glycine is not added to this list as it does not have a side chain.
Answer:
A coral reef can be described as an ecosystem of the ocean which is made up by reef-building corals. Coral reefs benefit the environment in a number of ways, one of them is protecting the shoreline. <em><u>Coral reefs tend to absorb most of the waves from the ocean and so help the coastline from erosion. It reduces the chances of ocean water waves to destroy the crops and buildings nearby and hence prevents erosion. </u></em>
