Suppose that brown hair (B) is dominant over blonde hair (b) and Curly hair (C) is dominant over straight hair (c)
1. Suppose a man who is heterozygous for black hair and has straight hair (recessive), marries a woman
who has blonde hair (recessive) and is heterozygous for curly hair.
What are the genotypes for these two parents?
Bbcc X bbcc
bo
BBcc X bbcc
с
BCC x bbcc
d
Bbcc x bbcc

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

you know they are heterozygous for a trait because they have it as jj or jj.
