Fault is a break or fracture in a block of a rock.
<u>Explanation:</u>
A fault is a term which is used in the subject Geology. A fault is a fracture or break in the continuity in a rock which result in the change in the place of the rock.

2. Horizontal movement
3. Swinging movement
4. Circular movement.
Answer: Option A.
The two types of chlorophyll are chlorophyll A and B.
Explanation:
Chlorophyll is the green pigments present in chloroplast (organelles) that is found in plants which is used for photosynthesis by reacting with carbon dioxide and water to produce carbohydrates. The two types of chlorophyll are; chlorophyii A and chlorophyll B.
Chlorophyll A is the primary photosynthetic pigment that absorb energy from blue- violet light and orange red lights wavelengths.
Chlorophyll B is the accessory pigment to receive energy and transmit it to chlorophyll A. Chlorophyll B absorbs energy from green lights wavelengths.
It happens through 3 stages
- Interphase
- Meiosis 1
- Meiosis 2
In Meiosis one the cell produces diploid daughter cells by combining homogeneous and heterogeneous chromosomes.
In Meiosis two these diploids again tear apart to produce haploid daughter cells
