A batsman is unlikely to score a century in every cricket match. This is an example of "partial reinforcement".
<u>Option: C</u>
<u>Explanation:</u>
Unlike constant reinforcement, partial reinforcement is only strengthened during certain times or time ratios, rather than emphasizing the action every single time. This method of arranging reinforcement is also called intermittent reinforcement after certain number of correct answers or certain interval of time. Thus here a batsman donot plan intentionally to make a century in every cricket match, but it goes random. Although when they need to score high on pressure, they force themselves to stretch as much possible which is not general.
It's a pyramid of numbers, I believe.
The correct statements are-
Erosion occurs even when the mountains are forming. Erosion is the movement of sediments from the broken rocks through the agents like gravity, wind, water and others. It is a constant process occurring even while the mountains are forming. It is affected by gravity.
When new mountains or plateaus form, the cycle starts over. Weathering is the breakdown of rocks by the weathering agents. These sediments move due to the process of erosion. A new sediment may be dropped nearby or in a new place by the process of deposition. Weathering, erosion and deposition occur together as a cycle and have almost leveled the land surface.
Weathering, erosion and deposition have almost leveled earth’s surface. These three processes occur as a cycle and have almost leveled the land surface.
Answer:
Passive transport.
Explanation:
The transport of molecules across the plasma membrane can occur by the two process- active transport and passive transport. No amount of energy is required during the active transport.
Passive transport includes the diffusion and osmosis. Both the diffusion and osmosis do not require energy and the molecules move down from the region of higher concentration towards the region of lower concentration. Small molecules, ions and proteins can go through the passive transport.
Thus, the correct answer is option (c).
