Use the scientfic method to design an experiment testing the hypothesis that cows produce a different amount of milk when fed freshly cut grass than when fed commercial feed. Identify dependent, independent, and controlled variables.

The experimental protocol is:

Two treatments are carried out, one of them with 10 cows that feed on freshly cut grass and another treatment with 10 cows that only feed on commercial food, it is important that the cows are dairy cows.

After 5 days of feeding them, for 10 days the cows will be milked by measuring the amount of milk with a container that measures liters and is equal.

Subsequently, a graphic analysis will be made with Liters of milk as a dependent variable and treatment 1 and time as a dependent variable in each of the treatments.In this case the amount of grass and the type of grass are controlled variables.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
