Answer:
Ty has two pet mice. One mouse has the gene for black fur color and the other mouse has the gene for white fur color. The female mouse is pregnant now, and Ty wonders what color or colors the baby mice will be. Read each offspring description phrase below and select the correct pattern of dominance for each.
___ all white fur offspring, white fur in this case is dominant
___ all gray fur offspring, this is incomplete dominant.
___ all black fur offspring, this is black fur dominantice
___ all black and white offspring, this is codominance .
Explanation:
Incomplete dominance: Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance.
Codominance: Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
Answer:
a) 1.75s b) 17.2 m/s (down)
Explanation:
d1= 15m d2= 0m (because it hits ground)
a= -9.81 m/s^2 t=???
Equation
the triangle means change in so d2-d1
Δd= v1 * t + 1/2 * a * t^2
0m-15m= v1*t + 1/2 a t^2
-15 m= 0m/s*t (goes away) + 1/2* a *t^2
-15mx2= t^2
-15mx2/a= t^2
Square root (-30/-9.81m/s^2)
t=1.75 s
b) now v2!!
Im going to use v2= v1 + a*t
v2= 0m/s + -9.81 x 1.75s
v2 = -17.2 m/s or you can say 17.2 m/s down!!!
