Answer:

Option E.

In order for oxygen in the inspired air to reach hemoglobin, it must diffuse across all of the following structures, except: one or two smooth muscle cells.

Explanation:

In the process of oxygen reaching hemoglobin it gets diffused across layer of surfactant, an endothelial cell, type I pneumocyte, and the plasma membrane of the erythrocyte.

The molecule that is responsible for the carrying of oxygen into the blood cells is protein hemoglobin.

The normal adult human's blood is the mixture of six different species of hemoglobin molecules. These all molecules consist of same function as well as structure.

Anna11 [10]

The correct answer is Broca's area or Wernicke's area.

What are the roles of producers consumers and decomposers in an ecosystem

mariarad [96]

Answer: The producers refers to green plants that carry out the process of photosynthesis in order to produce food for themselves and others. The principal function of producers is to manufacture food for themselves and all other living organisms.

The consumers refers to those living organisms that can not produce their own food and have to depend on the food produce by others. Consumers can be categorized into primary, secondary and tertiary consumers depending on where they are located on the trophic levels. They can also be classified as herbivores, carnivores and omnivores depending on the type of food they eat. The major function of consumers is transference of energy. Consumers transfer the energy they obtain from the food they eat to those animals that feed on them.

The decomposers are those micro organisms that are majorly found in soils.The principal function of decomposers is to break down dead organic matters so that they can be absorbed by the roots of plants. The broken down organic substances serve as nutrients, which the plants used to grow and develop.

These three types of organisms work together in the ecosystem to maintain the balance of the ecosystem.
