<em>Cone-Bearing Plants</em> also known as <em>Conifers, </em>are classified as Gymnosperms
Answer:Tay-Sachs is an autosomal recessive disease caused by mutations in both alleles of a gene (HEXA) on chromosome 15. HEXA codes for the alpha subunit of the enzyme β-hexosaminidase A. This enzyme is found in lysosomes, organelles that break down large molecules for recycling by the cell.
Explanation:
Answer:
Only some species may survive the event
Explanation:
Evolution is most likely to occur when catastrophic events alter community composition. Catastrophic global event can influence that only the hardiest, generalist species may survive. Specialists may be left without food and starve.

Explanation:
Sodium (Na) and Chlorine (Cl) are two electrolytes that play important role in the absorption of water and nutrients in the small intestine. However, as mentioned in the question, the release of sodium and chlorine would lead to a loss of water in the intestines. This is because of the OSMOTIC phenomenon.
Osmosis is the movement of water molecules from a region of high concentration of water/low concentration of solute to a region of low concentration of water/high concentration of solute via a semipermeable membrane. In this case, the Na+ and Cl- ions serve as the solutes, which when released out of the intestine causes the solution in the intestines to be HYPOTONIC compared to the intestinal environment. This causes an OSMOTIC GRADIENT.
This osmotic gradient i.e. difference in concentration provokes osmotic flow of water from the intestines, which has a low solute/high water concentration, to the outside of the intestines, which has a high solute/low water concentration. Hence, water is lost from the intestine because the solute concentration becomes low when sodium and chlorine ions are released.
Answer:
Phenotypes
Explanation:
'Phenotype' is just a fancy way of saying 'what an organism looks like'. Those words describe an organism's physical appearance and not its genetic makeup--that's its genotype.
You can remember it this way:
Phenotype
Physical characteristics/appearance
----
Genotype
Genetic makeup
