1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.
3) So it doesn't gather dust and fog up the lense? that one should be self explanatory
Answer:
Biodiversity
Explanation:
refers to all the variety of life that can be found on Earth (plants, animals, fungi and micro-organisms) as well as to the communities that they form and the habitats in which they live.
<span>The oldest known vascular plants in the northern hemisphere are Devonian
This is true</span>
Explanation:
The higher the volume of water in a stream, the higher its speed and the wide its size and shape which ensures a proportionate flow rate.
To quantify how the speed of stream, we use the quantity, discharge in hydrology;
Discharge is the volumetric rate of water flow past a point at a particular time.
Discharge =
- We see that discharge is directly proportional to the volume of water in a stream.
- It is inversely proportional to the time taken.
- We know that volume is the amount of space occupied by a body. It is function of its size and shape.
- A big water body that is deeper, wider and longer will have more wate and a greater discharge.
