Water, air, food. and heat.
Answer:
Energy added to cold water, E1
E1 = m•Cp•ΔT = 6 x 4.187x(42-20) = 6x4.187x22
Energy lost by hot water, E2:
E2 = X(CpΔT) = X x 4.187 x (75-42) =X x 4.187 x 33
So, since E1 = E2
6x4.187x22 = X x 4.187 x 33
X = 6x22/33 = 4.0kg
So the mass of the hot water added to the 6kg of cold water is 4.0kg
The expression or comment "Brain Freeze" means that the roof of your mouth is getting so cold that its affecting some of the nerves in your brain making it feel like a brain freeze.
ATP? Adenosine TriPhosphate
A cross between two linked genes was done in coupling configuration and in repulsion. In coupling, the recombination frequency is greater than 1/16 and in repulsion, the recombination frequency is less than 1/16
If the cross between two linked genes is in coupling, then the recombination frequency is greater than 1/16 having the genotype aabb and phenotype ab.
If the cross between two linked genes is in repulsion, then the recombination frequency is less than 1/16 having the genotype aabb and phenotype ab.
Coupling is the gamete entered having genes from identical parents having same inheritance.
Repulsion is the gamete entered from different parents having separate inheritance.
Genes in coupling configuration on a homologous chromosome have two wild alleles and two mutant alleles on the other homologous chromosome.
Genes in repulsion configuration have a wild allele on one gene and the second gene on other homologous chromosome having a mutant allele.
