Answer:
pulmonary ventilation and external respiration
Explanation:
Respiration includes pulmonary ventilation, external respiration, and internal respiration. Pulmonary ventilation is also called breathing and is the process of flow of air into and out of the lungs. It includes the flow of air between the atmosphere and the alveoli of the lungs and is driven by alternating pressure differences created by contraction and relaxation of respiratory muscles.
External respiration is also called pulmonary respiration. It refers to the exchange of gases between the alveoli of the lungs and the blood in pulmonary capillaries. The exchange occurs through the respiratory membrane. External respiration males the capillary blood rich in O2. The capillary blood loses CO2 during the process.
Answer:
C,D,,B) The molecule is likely a sugar.
Explanation:
The molecule is(hexose) a glucose.It is a sugar formed as the products of photosynthesis.It is also a carbohydrate because all sugars are CHO,although not all CHO are sugars.It is the smallest components of cell membranes.Protein are the largest components based on molecular mass,while phospholipids are the largest components.
The three major elements in the molecule are Carbon.Hydrogen and Oxygen. The general formula of carbohydrate is Cx(H2O)y. The ratio of hydrogen to oxygen is 2:1.Thus the hydrate refers to the water content.
Sugar as monosaccharide glucose is the simplest form with general molecular formula of (CH2O)n where may be n = 3 to 6. In glucose n=6,and it is called Hexose. Therefore the molecule of glucose is C6H1206 in ratio 1:2:1.
The arrangement of glucose could be in straight chain or ring structure,Hexose sugar of glucose and pentose can be ring structure.They have C-H chain length long enough to form ring structure.
In glucose this can either be alpha or beta ring structure. Therefore the molecule is either the alpha or beta-glucose ring.
Answer:
Population
Explanation:
A population in biology, is simply a group of individual organisms of the same species sharing a common gene pool that are dwelling in a similar habitat or geographical area. The individuals of a group have the capability to interbreed with each other to produce viable offspring that are fertile, however, interbreeding with other similar groups is usually not successful. Also, genetic variation exists within individuals of a population. Examples of a population are: mountain gorillas in Africa, African elephants etc.
