Which graph représents selection that may lead to reduced variatior
rewona [7]

The SECOND graph represents selection that may lead to reduced variation. It is an example of stabilizing selection.

<h3>What is Stabilizing selection?  </h3>

Stabilizing selection is a type of natural selection that leads to a  decrease in the genetic variation of the population.

In Stabilizing selection, natural selection tends to favor an average phenotype and then can remove (select) extreme variations.

Stabilizing selection generates a modified bell curve graph in which the central portion is narrower and it is taller than the normal distribution bell shape.

Which contraceptive method is 100 percent effective at preventing pregnancy?
emmainna [20.7K]

The correct answer is D. Abstinence

Explanation:

A contraceptive method or birth control method refers to a method used to avoid pregnancy or reduce the probability of getting pregnant. From antiquity, there have been different contraceptive methods but only in the last decades, methods have been designed based on science and its effectiveness has been studied.

Because of this, nowadays there are many contraceptive methods such as pills, condom, and implants that are about 80% to 95% effective, sterilization that is a around 98% effective and natural methods that have a lower percentage of effectiveness. But the only method that has been proven as completely effective or 100% effective is abstinence because by avoiding any type of sexual intercourse it is virtually impossible an egg can be fertilized by a spermatozoid.

A plant can produce either purple flowers or white flowers. What is the probability of purple-flowered offspring if two plants t
AnnZ [28]
You would be crossing Pp and Pp. If you put them in a punnet square, the four possible gene combination you get would be PP, Pp, Pp, and pp. In all cases except the last, the resulting flower's phenotype would be purple. So the probably of purple flowered offspring is 75%, or 3/4.
