b
Explanation:
this is because Invasive species are frequently generalists in terms of food, or habitat needs, have fewer predators in their introduced environments and are better able to exploit disturbances than their native competitors.
Answer:
During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.

You would have .3 of a chromosome for each new cell
Answer:
15.21 %
Explanation:
If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:
p + q = 1
p² + 2pq + q² = 1
where;
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
Given that p= 0.68 and q = 0.39
the percentage of the homozygous recessive genotype (q² ) will be
(0.39)² = 0.1521
= 0.1521 × 100
= 15.21 %
∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %
The answer is A.
A fish is biotic because it is alive; the creek is abiotic because it is not alive.
Both the bird and the berry are biotic because they are both alive.
