Answer: All of them seem to apply.

Explanation:

A., Its important to know if your car that is being collided is a small car or big truck, as they will end up effecting who gets hurt the most.

B., Same thing as A. but with the other vehicle.

C., The velocity matters a lot with a collision, since a slow crash won't have as much damage as a car going fast and hitting someone. Also it won't be as likely to be fatal if the car crashing into you is going slow.

D., This is the only one I'm not too sure on, but it seems like how fast the car can accelerate once collided with would be a big factor on whether it would come to a halt or skid across the road.

Which kingdom contains heterotrophs with cell walls of chitin?

kirza4 [7]

It would not be plants, even though it has cell walls. They are not made of chitin. Plants are also not heterotrophic.

Fungi, however, decompose other matter, and have cell walls made of chitin. This would fit the description.

In humans, the alleles for unattached earlobes is dominant over the allele for attached earlobes. The allele for dark hair domin

SVEN [57.7K]

First, let's define the alleles:

(Dominant) allele for unattached earlobes is E

Allele for attached earlobs is e

(Dominant) allele for dark hair is H

Allele for light hair is h

Heterozygous would mean that for both sets of alleles, they will be EeHh.

Now for a Punnett Square:

EH Eh eH eh

EH EEHH EEHh EeHH EeHh

Eh EEHh EEhh EeHh Eehh

eH EeHH EeHh eeHH eeHh

eh EeHh Eehh eeHh eehh

These are all the possibilities for the parents' offspring. Since the square is 4x4, then the number of genotypes is 16.

Now for the probabilities of each genotype (the amount of times a certain genotype appears divided by the total number of genotypes):

EEHH: $\frac{1}{16}$

EEHh: $\frac{2}{16}$

EEhh: $\frac{1}{16}$

EeHH: $\frac{2}{16}$

EeHh: $\frac{4}{16}$

Eehh: $\frac{2}{16}$

eeHH: $\frac{1}{16}$

eeHh: $\frac{2}{16}$

eehh: $\frac{1}{16}$

(If you ever want to check if your probabilities are off, just add them together and they should add up to the total!)

Hope this helps! :)
