Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2
2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2
3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4

The observation of the relationships between the anemone and clownfish supports the statement 'symbiotic relationships are important to an ecosystem' it is a fundamental ecological interaction.
<h3>What is symbiosis?</h3>
Symbiosis is a type of ecological interaction where both organisms are benefited from such interaction.
Symbiosis is a fundamental biological interaction that supports the delicate equilibrium (homeostasis) of both marine and terrestrial environments.
The relationships between the anemone and clownfish represent a piece of clear evidence that symbiosis not only helps these species but also the entire ecosystem.

Answer:
Explanation: The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
Answer:
Explanation:Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability
Answer:
Adverse effect on the animals.
Explanation:
If the rabbit population suddenly shrank due to disease, it will adversely affected the population of eagle, fox and coyote because these animals depend on them through feeding. Eagle, fox and coyote feed on the rabbit so if the population of rabbit decreases, then there will be scarcity of food for these animals and as a result decrease occur in their populations so we can say that adverse effect occurs on the population of eagle, fox and coyote.
