Lock and key theory states that enzymes have a specific shape that directly correlates to the shape of the substrate.
<h3>What is the lock and key theory of enzymes?</h3>
Enzymes are globular protein that catalyses a biological chemical reaction.
One of the characteristics of enzymes is that they are usually substrate-specific i.e. They bind and act to a particular substrate.
This characteristics is explained by the lock and key theory of enzymes, which states that enzymes have a specific shape that directly correlates to the shape of the substrate.

The parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).
<h3>What genotype and phenotype?</h3>
The genotype refers to the information present in an individual's genome. Unlike the phenotype, it is not observable and rarely changes. The phenotype, in turn, depends on a combination between our genotype and the environment and can be defined as the observable characteristics of an individual.
With this information, we can conclude that the parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).

Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Explanation:
The pith is the center of a stem and can store food.
Pith is the tissue that is located in the center of the stems of vascular plants. Pith is made up of soft spongy distinctive parenchyma cells which are large but have thin walls. The major function of pith is to convey nutrients to every part of the plant and to store nutrients in its cells.
