Explanation:
Answer:
B. An animal's weight
Explanation:
An animal's weight is the factor that does not influence population size in an ecosystem because this factor does not cause an increase or decrease the population of animals in an ecosystem. The birth and death rate of animals and number of animals in habitats are the factors that tells us about the increase and decrease in the population of organisms in an ecosystem but weight of organism can't affect the population.
Answer:
The work done by the gas expansion is 5875 J,
Since the work done is positive, the work is done by the gas on the surroundings.
Explanation:
Given;
change in internal energy, ΔU = -4750 J
heat transferred to the system, Q = 1125 J
The change in internal energy is given by;
ΔU = Q - W
Where;
W is the work done by the system
The work done by the system is calculated as;
W = Q - ΔU
W = 1125 - (-4750)
W = 1125 + 4750
W = 5875 J
Since the work done is positive, the work is done by the gas on the surroundings (energy flows from the gas to the surroundings).
Therefore, the work done by the gas expansion is 5875 J
Explanation:
According to the given data, the turnover number can be calculated as follows.
Turnover number = 
Therefore, moles of 
hydrolyzed is as follows.
Moles of hydrolyzed = 
= 
= 0.00682 moles
Now, moles of hydolyzed per second is calculated as follows.
Moles of hydolyzed per second = 
= 
And,
Moles of enzyme = 
= 
= 
moles
Therefore, the value of 
is as follows.
= 
per second
= 
per minute
= 
per minute
Thus, we can conclude that the turnover number () of carbonic anhydrase (in units of 
) is per minute.
