Answer:

bicarbonate-carbaminohemoglobin-dissolved in plasma

Explanation:

Transport of CO2 in the blood occurs in three main forms. Most of the CO2 is carried in the blood as bicarbonate. It accounts for transport of about 70% CO2. In RBCs, CO2 reacts with water in the presence of the enzyme carbonic anhydrase to form carbonic acid, which dissociates into H+ and HCO3-. Bicarbonate formation also occurs in blood plasma.

About 23% of CO2 is carried in the form of carbamino-compounds. Binding of CO2 to hemoglobin forms carbaminohemoglobin. The smallest percentage of CO2 (about 7%) is dissolved in blood plasma and is diffused into the alveolar air as it reaches the lungs.

What is the main source of carbon in an ecosystem?
sleet_krkn [62]

The main source of carbon dioxide in an ecosystem is the carbon dioxide gas present in the atmosphere. This carbon dioxide is used by the  plants and animals in different ways.

The plants use this carbon dioxide to perform the process of photosynthesis.This is carried out by the help of green pigment called chlorophyll that absorbs light from the sun, water from soil and carbon dioxide from atmosphere.

The carbon in animals comes when they eat these plants.

melomori [17]

Answer:

The experiment should have more different subject groups, with each group consuming a different amount of beta carotene.

Explanation:

When designing an experiment, to determine the effect of the amount of a substance, the experimental design should be done to accommodate more than two experimental group with each group treated with different amount of the substance and also a control group. This will enable the researcher to determine the effect of the different ranges of amount.

In the example, in other to determine if vitamin A is dependent of the amount of beta carotene consumed, there should be more different subject groups, with each group consuming a different amount of beta carotene.
