<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 tryptophan synthase enzyme catalyzes the synthesis of tryptophan. This enzyme is found in all kingdoms except animals.
Tryptophan synthase has a hydrophobic channel that facilitates the passage of an intermediate from one enzyme to the other during the biosynthesis of tryptophan, which makes faster the metabolic process.
Answer:
The average density of deer in 1923 was 1 deer per 8 acres
Explanation:
Given -
In 1923, the population of deer rose to 
The density of any species is equal to total population divided by total area of the land in which this population is residing.
Where d represents the density
P represents the population and
A represents the area of land
Substituting the given values in above equation, we get -
Thus, the average density of deer in 1923 was 1 deer per 8 acres
Answer:
The options are not included but the relationship between them is MUTUALISM.
Explanation:
The question depicts a relationship between two different species of organisms (hibiscus and bumblebees) called Symbiosis. Symbiosis can be of different types depending on whether the effect of the relationship on the involved organisms. The type in this case is MUTUALISM, which is a relationship between two organisms that are both benefitting from the relationship.
The bumblebees are benefitting from the relationship by getting fed from the nectar produced by the hibiscus flower plant while the hibiscus is benefitting from the relationship by getting its pollen transferred to another plant by the bees.
