Lamarck's theory cannot account for all the observations made about life on Earth. For instance, his theory implies that all organisms would gradually become complex, and simple organisms disappear.

Lamarck’s theory of evolution, also called as theory of inheritance of acquired characters was rejected since he suggested that the acquired character which an organisms gain through its life experiences are transferred to its next generation, which is not possible since acquired characters does not bring any change to an individual’s set of genes.

Carbon dioxide is carried from the tissues to the lungs by a variety of mechanisms. Which of the following lists these mechanism
Yakvenalex [24]

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.
