Why is the relationship between the corals and the algae in the coral reefs considered?
The relationship between the corals and the algae in the coral reefs considered because of mutualism.
Most reef-building corals have photosynthetic cells in their tissues called zooxanthellae. These unique cells and corals have a mutualistic interaction. The coral supplies the zooxanthellae with a safe habitat as well as the substances they require for photosynthesis.
In exchange, the zooxanthellae create oxygen and aid the coral in waste removal. Most significantly, zooxanthellae provide the coral with photosynthetic products such as glucose, glycerol, and amino acids.
These products are used by the coral to manufacture proteins, lipids, carbohydrates, and calcium carbonate. The interaction between zooxanthellae and coral polyps allows for tight nutrient recycling in nutrient-poor tropical environments.
Indeed, up to 90% of the organic material photosynthetically generated by zooxanthellae is transported to host coral tissue. This is the driving factor underlying coral reef development and productivity.
In addition to giving necessary nutrients to corals, zooxanthellae are responsible for the distinctive and stunning hues of many stony corals. When corals are physically disturbed, the polyps eject their zooxanthellae, and the colony becomes stark white.
This is referred to as "coral bleaching" in the industry. Coral bleaching can occur if polyps are left without zooxanthellae for an extended period of time.

with independent assortment, how many different types of gametes are possible from the genotype k/k, l/l, m/m, p/p and in what proportions are they expected?
with independent assortment each gene is 1/2 chance, so 4(1/2) = 1/16. 16 possible combinations, 1/16 chance of getting any one of them.
Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. According to the law of independent assortment, during the inheritance of two different traits, the alleles of both the traits assort and are inherited independently of one another during gamete formation.
Independent assortment occurs spontaneously when alleles of at least two genes are assorted independently into gametes. Consequently, the allele inherited by one gamete does not affect the allele inherited by other gametes. Mendel noted that the transmission of different genes appeared to be independent events. This gives both the trait equal chances of being inherited. Each gene is 1/2 chance, so 4(1/2) = 1/16. 16 possible combinations, 1/16 chance of getting any one of them.

there are two active sites in the functional enzyme (one in each subunit), but only one substrate molecule can be processed at a time. why is this? be sure to appropriately cite your source.
The reason why only one substrate molecule can be processed at a time in an enzyme with two active sites is due to a phenomenon called cooperativity.
Cooperativity is a process by which the binding of one substrate molecule to one active site of the enzyme affects the properties of the other active site. In the case of enzymes with two active sites, binding of a substrate molecule to one site results in a conformational change that makes it easier for another substrate molecule to bind to the second active site. However, this conformational change also results in the second active site being less efficient at catalyzing the reaction. Therefore, the overall efficiency of the enzyme is optimized for processing one substrate molecule at a time.

-sodium rush out of the cell, down the concentration gradient
-sodium ions may leave the cell, but are all pumped back in by Na/K-atpase pump
-sodium ions may enter the cell, but are pumped out by Na/K ATPase pump
When a red blood cell is placed in a hypertonic solution of NaCl, sodium ions rush out of the cell, down the concentration gradient.
This is because the hypertonic solution has a higher concentration of solutes, including sodium ions, than the red blood cell. As a result, water will also move out of the red blood cell, causing it to shrink and become dehydrated. The Na/K ATPase pump may work to pump sodium ions back into the cell, but it will not be able to keep up with the rate at which they are leaving due to the hypertonic solution. Therefore, the correct answer is "sodium ions rush out of the cell, down the concentration gradient."Similarly, the statement "sodium ions rush out of the cell, down the concentration gradient" is also incorrect, as the concentration gradient of sodium ions is actually in the opposite direction, from outside to inside the cell in this scenario.
The statement "sodium ions may leave the cell, but are all pumped back in by Na/K ATPase pump" is also incorrect, as in a hypertonic solution, the concentration gradient of sodium ions is from outside to inside the cell, and the pump works to remove excess sodium ions from the cell.

For example, Mendel would cross-pollinate a tall pea plant with a short pea plant, and then observe the traits of the offspring. He would then cross-pollinate the offspring with each other, and continue to track the inheritance of the height trait through several generations.
Through his experiments, Mendel was able to identify the principles of inheritance, including the concepts of dominant and recessive traits, and the law of segregation. His work laid the foundation for the field of genetics and our understanding of how traits are passed down from one generation to the next.
