Answer:
A. Solar energy being converted into chemical energy
Explanation:
Solar energy from the Sun is used by the primary producers which are plants through photosynthesis in the production of chemical energy. This validates the conversion of solar to chemical energy as a way of measuring primary productivity in the ecosystem.
The chemical energy which is in the form of molecules such as glucose(C6H12O6) are what the consumers feed on to enable sustainability.
Actually, heat energy is all around us – in volcanoes, in icebergs and in your body. All matter contains heat energy.
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
For example, an ice cube has heat energy and so does a glass of lemonade. If you put the ice in the lemonade, the lemonade (which is warmer) will transfer some of its heat energy to the ice. In other words, it will heat up the ice. Eventually, the ice will melt and the lemonade and water from the ice will be the same temperature. This is known as reaching a state of thermal equilibrium.
B. is slightly crooked when pressing the pedals
Body positioning while driving is to maximize control over your vehicle, comfort, and ensure that you don't suffer from back pain due to incorrect sitting posture.
To do this, make sure your bottom is firmly touching the back of the seat. Your seat should be raised high to give yourself maximum visibility and pulled back only enough, so that your knee is still slightly crooked when pressing down on the pedals.
Let me emphasize that you must make sure your seat is pulled far enough forward, so you can fully press the accelerator and the brake pedal, while still having a slight bend in the knee.
Answer:
In nearsightedness (myopia), the light rays form an image in front of the retina. In farsightedness (hypermetropia), the rays focus behind the retina.
