What is the purpose of dissecting a flower? What does it help us investigate?

Answer:

Flower Dissection A good way to learn about the reproductive parts of a plant is by dissecting a flower. Lilies, irises, or any flower with large parts work well for this project. Use flowers from your yard or check with a local florist for free discarded flowers.

If blood is splashed in the eye or any mucous membrane, flush the affected area with running water for:

fiasKO [112]

If blood is splashed in the eye or any mucous membrane, flush the affected area with running water for at least 15 minutes.

Have the person promptly rinse their eye(s) under running water, a warm shower, or a clean water container. Face of the individual should be held with the injured eye down and to the side. A high-pressure water stream should never be directed at the eye or eyes.

Use warm water to flush for 15 to 30 minutes.

<h3>What are the risks of infection from blood?</h3>

The likelihood of contracting an infection increases if you break or pierce your skin while coming into contact with contaminated blood. For instance, if you pierce your skin with a sharp tool that has contaminated blood on it, like a used needle.

If blood only comes into touch with your eyes, mouth, nose, or already broken skin, the danger of contracting an infection from it is reduced. For instance, if someone spits in your face, their saliva may contain blood and could end up in your mouth, nose, or eyes.

Additionally, infectious saliva may enter an already open wound, graze, or scratch. If infected, there is relatively little danger of infection. If infected blood comes into contact with intact skin, the chance of infection is quite low.

In a population of 10,000 individuals of Monstera deliciosa, four individuals have a variegated phenotype that is caused by the

Mariulka [41]

Under the assumption of this population being in Hardy-Weinberg equilibrium, the probability for the fixation of the var recessive allele equals 0.02 = 2%

--------------------------------

Available data:

N = 10,000 individuals ⇒ Large population

4 individuals have a variegated phenotype

variegated phenotype is caused by the recessive var allele

No selection, no additional mutation ⇒ we can assume Hardy-Weinberg equilibrium

We need to know the probability for the fixation of the var allele.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of variegated individuals in the population.

There are 10,000 individuals, and only 4 have variegated.

So, the phenotypic frequency, F(Var) is 4/10,000 = 0.0004 = 0.4%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(vv) = 0.4%

Finally, we can get the allelic frequency by taking the square root of this value.

F(vv) = q² = 0.0004

f(v) = q = √0.0004 = 0.02 = 2%

According to these calcs, the probability for the fixation of the var allele is 2%, and the probability that all individuals express the variegated phenotype is 0.4%.
