Describe a hypothetical example showing how rising sea levels due to global warming might cause extinction.
german

Answer:

Global warming may cause more icebergs to melt than are created. This would lead to higher sea levels. Sea levels may rise above land masses located at low elevations. As a result, the animals who lived in these areas may find their habitats shrinking and resources depleting, causing their population size to decrease. If there are particular species that were only able to survive in the areas now covered by water, they may very well become extinct.

Jenner's successful use of cowpox virus as a vaccine against the smallpox virus was due to the fact that ______. (A) the cowpox
irinina [24]

Answer: option C) cowpox and smallpox are caused by the same virus

Explanation:

Cowpox is a skin disease that affects cattle. It is caused by an Orthopoxvirus, with lesions occurring principally on the udder and teats of the animals.

Human infection may occur from touching infected cows, and thus giving immunity to smallpox (an acute infection caused by the same poxyvirus, in HUMANS)

So, Jenner's successful use was because cowpox and smallpox are caused by the same virus

What is the probability that the offspring will have purple flowers?; What is the phenotypic ratio for the purple flowers?; What
Luda [366]

The probability that the offspring will have purple flowers is 50% chance Let's go ahead and assume that:

The allele A corresponds to the color of flowers.

As a result, A would stand in for the alternate white hue and represent the dominating purple color.

According to the aforementioned hypotheses, a white flower would have the genotype aa while a heterozygous purple blossom would have the genotype Aa.

Now let's connect the two flowers:

Aa x aa

Aa Aa aa aa

The genotypes, phenotypes, and odds of the offspring would be as follows based on the cross's outcomes:

Purple color, Aa; 1/2

white flower color, aa, 1/2

In other words, there is a 50% chance that the cross will result in offspring with the flower colors purple (genotype, Aa) and white (genotype, aa).
