B. More; less; phototropism
Explanation:
Auxin is a hormone which is involved in the plant growth and the development by increasing the flexibility of the cell wall of the plant.
In the given question, the vertical root is rotated to the horizontal orientation which will be sensed by the roots and the roots will then redistribute the auxin in the roots.
The auxin will be transported to the lower areas but the growth of the root in the lower portion will be lowered as a result of which root will grow downward. This is considered a condition called positive gravitropism or negative phototropism.
Since the distribution of auxin is dependent on the presence or absence of light therefore this phenomenon will be referred to as the phototropism.
Thus, Option-B is correct.

Geologists classify crystals into six groups based on the number of axes and the angles of the facets, or faces, on a specimen. The science of crystallography labels the six categories as isometric, tetragonal, orthorhombic, monoclinic, triclinic and hexagonal.
Answer:it was very effective.
Explanation:
According to report in America 1954, Salk conducted a national study, with over a million paediatric subjects wish yielded a positive outcome and on 12 April 1955, the vaccine was considered safe and efficacious. in 1955, the vaccines was used for over 29,000 cases of poliomyelitis in the US and the infection rate reduced to less than 6,000. This made Salk vaccine more recognized and it was speedily adopted worldwide reaching almost 90 countries in less than 2 years after it mass production.
A substance that is produced by a plant that affects how it grows and develops is called a HORMONE
