The weight gained by Cricket within the 1-year period would be 8.75 or 8 3/4 pounds.
- Cricket weighed 3 3/4 pounds initially and 12.5 pounds after one year.
- In order to calculate the weight gained within the said period, the initial weight would be subtracted from the final weight.
Thus:
Weight gained = 12.5 - 3 3/4
= 12.5 - 3.75 or 12 1/2 - 3 3/4
= 8.75 or 8 3/4

Your nerves send feedback to the brain to tell you what you are touching. I suppose that is a feedback mechanism. I dunno if it is entirely helpful.
Answer:
21 minutes or 0.35 hours
Explanation:
The formula for exponential population growth is
where
initial population of E.coli i.e 100
k is the rate of population growth i.e 2 as the population doubles
t is the time period i.e 20 minutes
Substituting the given values in above equation, we get -
Generation time
minutes
or 0.35 hours
Answer:
In areas of Africa where malaria is prevalent the number of sickle cell cases remains consistent generation after generation. ---- support the hypothesis.
In Canada the incident of sickle cell anemia has been increasing in the population. ----- contradicts the hypothesis.
Explanation:
In areas of Africa where malaria is widespread the number of sickle cell cases remains consistent generation after generation while on the other hand, In Canada the incident of sickle cell anemia are lower in the population because of environmental condition is not good for increase in malarial disease. In Africa, the environment is suitable for the mosquitoes that causes malaria so there is high increase of sickle cell anemia in the population.
Answer is c. If one essential nutrient within an ecosystem runs out, primary productivity will be limited
According to Vitousek et al., 2010, nutrient limitation defined as meaningful additions of an essential element in biologically available forms which increases the rate of primary productivity or increase in the biomass in an ecosystem. Alternately, nutrient limitation may also explained as when the supply of one essential nutrient of the ecosystem runs out the primary productivity of the plants will be limited.
