Answer:
Explanation:
The ecological interaction between the sea anemone and monster crab is said to be a mutualism.
Mutualism is an ecological interaction between two or more species where all the parties benefits.
The sea anemone-boxer crab relationship as described is a mutualism. The anemone provides protection from predators of the crab using its powerful stinging claws. This prevents the crab from enemies. The anemone in return is able to get nutrient from the leftovers of the crab. Both organism serve a need for another and depends on one another for life.
2. For a parasitic situation to surface, one fictional assumption would be that, the boxer crab keeps getting protected by the stinging claws of the Anemone. The boxer crab on the other hand does not leave any leftover behind for the anemone to feed on.
In parasitism, only one specie benefits while the other loses from the relationship. If the boxer crab feeds without leaving any remnants, the sea anemone would get no nourishment. This might hamper the survival of this specie.

I believe that aquifer is the correct answer.
Answer:
B) 50%
Explanation:
Recessive alleles need two be present in both homologous chromosomes to express and to observe the phenotype they determine in the individual.
The possible genotypes and phenotypes for fur pigmentation in tigers are:
- aa: white
- Aa: normal
- AA: normal
The phenotypically normal heterozygous tiger is <em>Aa</em> and is crossed with a white tiger <em>aa</em>.
The Aa tiger produces 1/2 <em>A</em> gametes and 1/2 <em>a.</em> The aa tiger only produces <em>a</em> gametes.
<u>The possible offspring resulting from the combination of those gametes is:</u>
- 1/2 Aa: normal
- 1/2 aa: white
So 1/2 = 50% of the offspring will be white.
