Q1. Which category is described: 'basic unit; most shared characters'?
- A.Species
- B.Family
- C.Order
- D.Class
Answer: A. Species
Quick parse - a typical biology numerical. We are after the quantity the stem asks for. Tool of choice - F = m*a, V = I*R, n = m/M, v = f*lambda, KE = (1/2) m v^2). Rearrange it for the unknown before substituting. Numbers in: F = m*a, V = I*R, n = m/M, v = f*lambda, KE = (1/2) m v^2). Common-sense check: recall the defining law / equation for the named quantity (e.g. Lock in option A) Species. Trap-watch: option B) 'Family' is incorrect: Family: a group of related genera; option C) 'Order' doesn't hold - Order: a group of related families.
Q2. Which category is described: 'a group of closely related species'?
- A.Genus
- B.Order
- C.Class
- D.Phylum/Division
Answer: A. Genus
First, read what's there - a typical biology numerical. We are after the quantity the stem asks for. Tool of choice - valency = group number (I, II, ...) or 8 - group (V-VII). Rearrange it for the unknown before substituting. Numbers in: valency = group number (I, II, ...) or 8 - group (V-VII). Common-sense check: the modern periodic law: properties of elements are periodic functions of their atomic number. Lock in option A) Genus. Trap-watch: option B) 'Order' doesn't hold - Order: a group of related families; option C) 'Class' misses the point - Class: a group of related orders.
Q3. Which category is described: 'a group of related genera'?
- A.Family
- B.Class
- C.Phylum/Division
- D.Kingdom
Answer: A. Family
Asked for the unknown; data is laid out in the stem. By valency = group number (I, II, ...) or 8 - group (V-VII). valency = group number (I, II, ...) or 8 - group (V-VII). the modern periodic law: properties of elements are periodic functions of their atomic number. Hence option A) Family. Others fail: option B) 'Class' fails since Class: a group of related orders; option C) 'Phylum/Division' doesn't hold - Phylum/Division: a group of related classes.
