The correct answer is the root Cap
Answer:
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
Explanation:
The correct answer is option A, that is, a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom.
Carbohydrates are the main source of diet, they provide energy to the body, mainly via glucose, a basic sugar, which is a part of the starch and an ingredient in various staple foods.
The carbohydrates can be signified by the stoichiometric formula, that is, (CH2O)n. It can be also be stated that the ratio of the carbon to hydrogen to oxygen is 1: 2: 1 in the molecules of carbohydrates. Carbohydrates are further categorized into three sub-kinds, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the simple sugars, for example, glucose.
Answer:
Rate and depth.
Explanation:
Breathing may be defined as the process of intake of oxygen and exhalation of carbon dioxide. The inhalation and exhalation depends on the partial pressure of gases, atmosphere and pressure of alveoli.
The breathing rate can be changed easily by increasing or decreasing the time of inspiration and the expiration. This changes the volume of oxygen and carbon dioxide in the body. The depth of breathing is controlled by the respiratory center present in the brain. The stimulation of the accessory muscles may increase the thoracic volume change and alters the breathing depth.
Thus, the answer is rate and depth.
