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
Because humans are omnivorous thus they can feed on different organisms. They can never occupy the lowest levels because they are not omnivorous.
The results clearly reveal that Imipramine is by far more effective than Lithium in preventing the recurrence of depression. 62.16% of the patients taking Lithium had a recurrence of depression which is more than twice that of patients who took Imipramine (28.95%).
The results also question the effectiveness of Lithium in general since the percentage of patients who had a recurrence of depression in the Placebo group (67.65%) is only slightly higher than that of the Lithium group (62.16%).

Answer and Explanation:
To calculate the allele frequency in the population, we divide the number of occurrences of the particular allele by total number of all alleles in the population Allele frequencies can be represented as a decimal, a percentage, or a fraction.
Given the population of white (W) and black (w) sheep, 22 out of 244 sheep are black, the frequency of the dominant allele in the population = 222/244×100=
