Answer:
Protozoa are single-celled eukaryotes
Explanation:
Eukaroytes are organisms whose cells have nuclei
Answer:
The correct answer would be They comprise the Calvin cycle.
Calvin cycle refers to the set of chemical reactions taking place in the stroma of the chloroplast in which carbon is fixed into food (glucose). The whole process is divided into three stages namely: fixation, reduction, and regeneration (ribulose bisphosphate or RuBP).
It takes place in light-independent reaction of the the photosynthesis.
It does not require light energy to carry out the reactions however, it depends upon the products of light reaction (ATP and NADPH).
Fixation of one molecule of glucose requires 6 molecules of carbon dioxide, 9 ATP and 6 NADPH.
The fixation of carbon is catalyzed by an enzyme RuBisCO.
Protein function is directly related to the structure of that protein. A protein's specific shape determines its function. if the structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.
False. Oxygen is absorbed in the alveoli sacs of the lungs.
Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.
