<span>The specific heat of the metal is 0.5 cal/ (0C.g). This means the energy needed is 0.5 cal to raise the heat of 1 gram of metal by 1 degree C. Therefore, the energy needed to raise 100 g of the metal by 20 degrees C is:
0.5 * 20 * 100 = 1000 cal.

Answer:
The homozygous dominant phenotype is higher than expected, indicating that evolution has occurred.
Explanation:
At the start there are 200 fishes in the pond, 100 of them are AA(50%) and 100 of them are aa(50%). Using the Hardy-Weinberg Equilibrium equation we can say that the gene frequency is
A=0.5
a=0.5
With those frequency, the expected percentage of offspring with dominant genotype will be:
AA= 0.5 * 0.5 = 0.25 = 25%
The number of homozygous dominant found is 35% which is higher than expected (25%). Higher homozygous dominant frequency than expected means the Hardy-Weinberg Equilibrium is changed. In this case, evolution probably the cause that shifts the gene frequency.
<span>Using a genetic cross, we can look at the following
A = brown a = White, B = Tall, b = small
With the capital letters being the dominant allele
A a
B AB aB
b Ab ab
The allele we are looking for is Ab which as 1/4 chance
To work out how many are in 2/6 also (1/3)
we do 1/4 x 1/4 x 1/4 = 1/64</span>
The hormones send signal to the mammary glands in the body for it to start to produce milk to feed the baby. However there are times humans rely on to cow's milk. There are differences though between the two.Human milk has more whey protein compared to the cow yet they has less casein which is another type of protein compared to cow's milk. For carbohydrates, human milk is higher than the cow's milk. For the fatty acid, the cow's milk contains more unsaturated fat.
The cell cycle is regulated at the molecular level by a set of protein known as CYCLIN . Cyclin are a core regulator of the cell cycle. They are group of related proteins and four different types have been identified in humans. Each cyclin is associated with a particular phase of the cell cycle.
