Pedigree is the symbolic representation of the history of an individual's family connections, presenting their ascendants and descendants in an organized manner. This is an important instrument in the genealogical process, as it is a way of gathering data about the ancestors of the members who participated in a person's family building so that the connections between these individuals are established.
The family pedigre shown in the above question would be:
Hanna's mother and Hanna's father have three daughters of Hope's order, Holly and Hanna. Hanna and Harry have a son named John. John is married to Jane. His children are Lee and Leah (diagnosed with galactosemia
). Janes's mother is Hilda and the brother is Joe. Joe is married to Jen and his son is Les.
The best answer is b - it is rigid.
The cell wall is defined as the rigid, outermost layer found in plants and also certain bacteria, algae and fungi. It is absent in animal cells.
The plant cell wall is made up cellulose which is a structural carbohydrate. The cell wall is rigid and thus offers structural support allowing plant such as trees to grow to great heights.
It also helps prevent water loss, helps protect against insects and pathogens and keeps the shape of the plant.
