Answer – DNA (Deoxyribonucleic acid)
The DNA provides the information for cell growth and function of all known living organisms. It also carries the information for their development and reproduction. Most of the DNA is located in the cell nucleus (in this case, called nuclear DNA), but some amount of DNA are also contained in the mitochondria (in this case, called mitochondrial DNA)
Answer:
d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell
Explanation:
An axon is a fiber of the nerves that transmits nerve impulses( electrical signals) away from a cell body and towards another neuron, muscle fiber or gland cell.
We have two types of axons in the body.
a. Myelinated axons
b. Unmyelinated axons.
The difference between Myelinated axons and Unmyelinated axons is that the Myelinated axons has an external covering or insulation which is called the myelin sheath.
The myelinated axons are very numerous and mush faster than the unmyelinated axon.
Answer:
A disaccharide combines with water to produce two monosaccharides in the process known as hydrolysis.
Explanation:
Disaccharides are formed by joining of two monosaccharide units with the release of a water molecule. This type of reaction is called a condensation reaction.
A hydrolysis reaction is the opposite of a condensation reaction. It is a reaction in which a single molecule of water breaks different kinds of bonds. Hydrolysis causes a disaccharide to join with a water molecule to break it back into its two monosaccharide units.
Answer: The human body is organized at different levels, starting with the cell. Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems
Explanation:
Distance is the length of the path travelled
displacement is the shortest length of the path travelled
distance does not have direction, hence, it is a scalar quantity
displacement has direction, hence, it is a vector quantity
