Answer:
Motion is defined as phenomenon in which an object move from one place to another over a time.
Generally there are four types of motion: Linear, rotary, reciprocating and oscillating.
Linear motion: In this motion an object moves in a straight line. for example: an athlete running in a straight line.
Rotary motion: In this motion an object moves around an axis. For example: Wheel.
Reciprocating motion: In this motion an object moves in a continuous up and down motion or back-and-forth motion. For example: piston.
Oscillating motion: In this motion an object moves in a swinging motion (backwards and forwards) on an axis. For example: Pendulum.
Answer:
d. With the direction of gravity
Explanation:
- Geotropism or gravitropism is a coordinated process of plant growth in fungi and plants to respond to the changing gravity. It a general feature that are found in higher and lower altitude plants.
- The roots show positive gravitropism and the stem negative gravitropism this they appear to be bend upside on a hill or slope. Can be seen with a potted plant, was the woody stems are capable of bending.
Answer:
Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.
