Answer:
C: All offspring with at least one R will have red flowers.
Explanation:
Mendel's Law of Dominance states that: “In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.”
This simply means that if there exists two contrasting traits (I.e Rr), one of the traits will always suppress the other, thereby expressing itself. R suppresses r, thus making the offspring with big R have red flowers. The trait is called a dominating trait and the suppressed is called recessive trait.
zooplankton
algae
predatory birds
small fish
The correct answer is predatory birds.
The flowing of toxic chemicals and heavy metals into the water body when the agricultural, industrial, and human wastes run off or are discharged intentionally into the water body is known as biomagnification. These pollutants result in genetic mutations, disease, reproductive difficulties, birth defects, death, and behavioral modifications in various marine species.
However, the extremity of the destruction varies significantly among the species. In various circumstances, the animals close to the top of the food chain are most influenced by the procedure of biomagnification.
Several of the harmful toxins get settle at the lower level in a water body and are then consumed by the species, which feed or live on the bottom dwellers. As these constituents are not digested, they gathered inside the bodies of the species, which consumes them.
It signifies that the higher level predators, like fish, birds, or marine mammals accumulate more harmful concentrations of toxic substances in comparison to the animals lower on the food chain. Thus, in the given case, the more concentrated amount of toxins would be found in the predatory birds.
In a large lake ecosystem, the population with the highest concentration of the toxin would likely be the zooplankton. This is because they consume contaminated algae, transferring and concentrating the toxins in their bodies.
The population with the highest concentration of the toxin in a large lake ecosystem would likely be the zooplankton. Zooplankton are primary consumers that feed on algae, which is where the toxin would accumulate. As they consume contaminated algae, the toxin would be transferred and concentrated in their bodies.
Although other organisms like ducks, predatory birds, and small fish may also be affected by the toxin, the highest concentration is expected in the zooplankton because they have a direct dependence on the algae.
This scenario is applicable to a Biology class in High School, where students learn about ecological interactions and trophic levels.

Answer:
Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch.
Answer:
The correct answer would be hybridization.
Hybridization refers to the process by which organisms of different breed, species, or varieties are selectively interbred in order to produce offspring with desired characters.
Similarly, Maltese dogs were selectively bred in order to attain characters like the small size, less shedding of hairs et cetera.
