Answer:
Option 1. i.e. They are the most abundant type of cell in a typical plant body.
Explanation:
Parenchyma cell are cells that are present in plant body to perform cellular respiration and photosynthesis. These type of cell are most easily available cells which present in large amount in any typical plant body.
There are many roles that parenchyma cells may serve. Their work is mainly based on their place in the plant, which can define if they will be used in storage, photosynthesis, or repair damage.

Answer:
d. Meiosis II in the father
Explanation:
Since the son has two extra Y chromosomes, the nondisjunction would have occurred in father because females do not have Y chromosome. Before Meiosis DNA replication occurs during which the homologous chromosomes are replicated. During Meiosis I crossing over occurs and homologous chromosomes separate from each other. During Meiosis II sister chromatids of a chromosome separate and move into individual daughter cells.
Here, during Meiosis II the sister chromatids of Y chromosome did not separate from each other (nondisjunction). They collectively moved to one daughter cell. As a result one daughter cell had two Y chromosomes and other daughter cell had none. When the daughter cell containing two Y chromosomes combined with the daughter cell containing one X chromosome from mother, XYY individual was born.
Pros: It is abundant, and can be used without interruption, cleaner than fossil fuel. Cons: Can result in air pollution, takes a lot of energy to produce, can be seasonable and competes with food production. Landfill gas, solid waste energy comes from harnessing the decomposition of organic material.
