Answer: All Viruses are obligate intracellular parasites that can only replicate inside a host cell.
Explanation:
Obligate intracellular parasites are parasite that cannot complete their life cycle or live outside a host cell . They become living and replicate in a host cell. Viruses are obligate intracellular parasites that reproduce and grow inside a host cell by using the intracellular resources in the host cell. Examples are human deficiency virus (HIV), AIDS virus, bacteriophage e.t.c.
Answer:
cell wall and nucleus are the answers
Answer:
The correct option is;
D. 45%
Explanation:
From the Hardy- Weinberg law, we have;
p² + 2·p·q + q² = 1
p + q = 1
Where:
p = Dom inant allele frequency in the population
q = Recessive allele frequency in the population
p² = The percentage of individuals in the population that are hom ozygous dominant
q² = The percentage of individuals in the population that are homo zygous recessive
2×p×q = The percentage of hete rozyous individuals in the population
The number of individuals that express the recessive phenotype = 86
The number of individuals in the population = 200
The percentage of individuals that express the recessive phenotype, q² = 86/200 = 0.43
Therefore;
q = √0.43 = 0.656
p + q = 1
p = 1 - q = 1 - 0.656= 0.344
∴ The frequency of individuals that express the do minant phe notype, p = 0.344
The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%
Answer:
b. Disorder
Explanation:
The universe has no means or organization, it moves in a state of disorder.
