Predict the fur color of the offspring of a brown heterozygous rabbit and a white homozygous rabbit. Brown is dominant and white
fgiga [73]

Answer:

To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:

        b        b

B   Bb         Bb

b   bb         bb

The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.

there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.

True or false: during stressful events, there is decreased blood supply to the skin, which results in "goose bumps."
Sonbull [250]
False.
In a stressful event, there will be a hormone released to the blood called adrenaline. Adrenaline hormone can prepare the body for fight or flight response. One of the effects of this hormone is making the muscle around hair called musculus arrector pili contracted. This contraction of the muscle is what causing the goosebumps. The decreased blood supply has no role in this event.

Which organisms are not examples of an adaptive radiation?
gavmur [86]

Answer:

Option B, Mammals and reptiles in the post-dinosaur age.

Explanation:

Adaptive radiation is mechanism through which species evolve very fast from common single ancestors. In simple words two different species are said to have evolved through adaptive radiation when they have descended from a single lineage. This is not the case with mammals and reptiles.  

Generally in adaptive radiation, a species evolve when it faces new environmental challenges due to change of habitat or area. For example mammals have evolved from dinosaurs.  

Hence, option B is correct
