Answer:
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.
Explanation:
The correct answer is option B a molecule.
Cells are the basic structural and functional units of living organisms. If a bunch of keys represents a cell, each key in the bunch represents a molecules. The levels of organization in an organism is as follows.
atom ⇒ molecule ⇒ cell ⇒ tissue ⇒ organ ⇒ organ system ⇒ organism.
Molecules represent the keys in a key bunch. A molecule is made up of one or more atoms held by chemiclal bonds. A cell is made up of various biomolecules. The cell wall consists carbohydrates, cell membrane consists of fats and proteins, the cytoplasm of the cell consists of water molecules, proteins, fats, carbohydrates and the nucleus has the biomolecules called the nucleic acids. Thus, many such biomolecules make up a cell.
Answer:
Option B, kinesthesia
Explanation:
Kinesthesia is also known as Kinesthesis. It is the study of determining both the conscious and unconscious owns' body movements through perception . It makes an individual able to find the change in the position and movement of the body without depending on information from sense organs. However, the senses received from the sensors located in tendons, joints, and muscles also helps us in perceiving this information.
Hence, option B is correct.
