Answers

I think you wanted to know whether the statement in question is true or false. Based on this assumption, i am answering this question and hope that it helps you. It is absolutely true that the slash and burn system of deforestation reduces the number of oxygen producing and puts more carbon in the air.

Answer: True

Explanation: Slash and burn deforestation increases the amount of carbon-di-oxide as a result of combustion. The burning process releases carbon-di-oxide into the atmosphere this depletes the amount of the oxygen in the atmosphere. The trees that are cut down liberates oxygen during photosynthesis, there won't be oxygen from the deforested trees.

Hence, If an organism has allele BB then he has a homozygous dominant trait.

Where is the moon when you are in a location experiencing a low tide?A. directly over head at your location
B. on the opposite side of the Earth from you
C. halfway between you and the opposite side of the earth
D. over the north pole or south pole

Answers

Answer:

Explanation:

The gravity of the sun and moon pull on the water of the oceans of the earth hence causing a bulge of these waters at the point on earth where the moon is above. The region where the moon is above, and the opposite side on the earth, will therefore experience high tides while the places at right angles (on the surface of the earth in relation to the moon position) will experience low tides.

John is a newly diagnosed diabetic that contacts the office with complaints of severe nausea and vomiting. What instructions should the APRN provide related to his insulin doses?

Answers

Every 4 hours, check your blood sugar levels and take regular insulin based on the results.

What is the effect of insulin?

A glucometer is typically used to measure blood sugar levels during sliding-scale insulin therapy regimens.

About four times per day, this is performed (every 5 to 6 hours, or before meals and at bedtime). Your bloodsugar reading determines how much insulin you receive at mealtime.

The following factors determine whether an APRN is allowed to prescribe prohibited medications to patients: A patient has been given an oral medication with a high first-pass effect.

Therefore, every 4 hours, check your blood sugar levels and take regular insulin based on the results.
