Pathogens are microorganisms - such as bacteria and viruses - that cause disease. Bacteria release toxins and viruses damage our cells. White blood cells can ingest and destroy pathogens. They can produce antibodies to destroy pathogens, and antitoxins to neutralize toxins

100 individuals whose genetic makeup is composed of 20% recessive alleles join an established population. The established popula
NeX [460]

Answer:

population = 600

heterozygotes = 2pq

The homozygous recessive percentage = q^{2}

q = 0.1

Solve for q:

∴ q = \sqrt{q}

∴ q = \sqrt{0.10}

∴ q = 0.316

solve for p:

for p + q = 1,

thus p = 1 – q = 1 – 0.316 = 0.684  

The heterozygotes = 2pq

2pq =  2 x 0.316 x 0.684 = 0.432

600 x 0.432 = 259.2  = 259

so,  the population reaches Hardy Weinberg equilibrium, 259 of indviduals should be heterozygous for this trait.

Hence, the correct answer is 259 .

Which statement is FALSE? A. Phototropism and geotropism are adaptations of plants that allow for survival. B. Tropism is the gr
MariettaO [177]

Answer:

A. Phototropism and geotropism are adaptations of plants that allow for survival.

Explanation:

Ideally, TROPISM is the growth response of plants to their environment due to external stimuli as rightly stated in this question. However, based on what stimulus the plant is responding to, there are different types of stimulus.

Phototropism (photo-light) is the response of an organism to a light source while Geotropism (geo- gravity) is the response of an organism to gravity. Hence, based on this question, a plant's response to moonlight is phototropism while it's response to gravity is geotropism.

Also, tropism can either be positive or negative depending on whether the response is towards the stimulus (positive) or away from the stimulus (negative). Therefore, the FALSE statement is "Phototropism and geotropism are adaptations of plants that allow for survival"
