Answer:
The animal cell will shrink due to loss of water to the external solution
Explanation:
An isotonic solution is that solution which has equal concentration with its external environment. Hence, no net movement of water occurs in an isotonic solution since there is no concentration gradient. Therefore, if an animal cell is placed in an isotonic solution at first, no net movement of water occurs because the intracellular and extracellular concentrations are at equilibrium.
However, if more solutes are added to the solution, it makes the solution HYPERTONIC to the cell i.e greater in concentration. This creates an osmotic gradient and causes water to move out of the animal cell into the solution in accordance to osmotic principles (movement of water from a low concentration of solute to high concentration of solute). This causes the animal cell to likely SHRINK.
The correct answer is C4 plants.
A plant that cycles carbon dioxide into four-carbon sugar components to get into the Calvin cycle is known as a C4 plant. These plants are very effective in dry, hot climates and produce ample energy. Various foods one consumes are C4 plants like pineapple, corn, and sugar cane.
In the C4 plants, at the start carbon fixation occurs in the mesophyll cells and the Calvin cycle occurs in the bundle-sheath cells. The PEP carboxylase combines with an incoming molecule of carbon dioxide to the three carbon-molecule PEP, generating a four carbon molecule, that is, oxaloacetate.
Answer:
The correct answer is "exchange of genetic information between parental chromosomes".
Explanation:
Homologous recombination is a genetic recombination that occurs when two similar or identical molecules of DNA exchange some of its nucleotide sequences. This type of recombination is most widely used for DNA repair purposes, however this is not distinctive of eukaryotes as prokaryotes use it as well. Therefore the most significant an unique role of homologous recombination in eukaryotes is the exchange of genetic information between parental chromosomes. This particular function is known as chromosomal crossover and it is only found in eukaryotes.
