However, the amount of food they produce is MUCH MUCH less than the amount of food produced by the leaves.

It is actually mist made out of tiny water droplets, like the white 'smoke' we see from a boiling kettle or the clouds in the sky.

Water vapour in our exhaled breath loses heat to the cold air in the surroundings (because it is a cold place) and condenses (changes from gas to liquid) into tiny water droplets.

Hence, we can see this mist.

It is the colour of the clouds. Before it rains, there are many tiny water droplets in the sky, which is what clouds are made out of.

You will notice that the clouds appear red/orange/yellow in cities or areas with a lot of lights. This is because the light from the street lights (which are usually orangish) shines into the sky as well. This reaches the clouds and is reflected back into our eyes. Hence, we see red/orange/yellow.

Glass only easily breaks when it is thin. Glass is very strong when it is thicker. It will only break when a large force is applied (like something smashing through it or it falling on the floor).

Ceramic is also similar, it is considered to be strong.

Both glass and ceramic are brittle. Brittle means that they do not bend and will shatter break when a large force is applied. Some materials are strong but not brittle, like plastic. Plastic will usually bend instead of shattering.]]> 2021-11-30 02:25:36 UTC https://padlet.com/mrrahull/QuriosityP3P4/wish/1919394080 MrRahull https://padlet.com/mrrahull/QuriosityP3P4/wish/1919396003 Paper is made after 'breaking' many pieces of wood and 'joining' them together. Hence, paper is much weaker than the original wood from which it is made from.

One of these factors is density. The lower the density, the better that object is at floating.

Wood has a lot of air spaces inside it, so it has a very low density and can float.

You are right that wood absorbs water. After a VERY LONG time, wood will absorb water and sink. However, this takes so long that we don't really see it happen. Hence, we see that wood floats.

Metal has a much higher density so it sinks quickly.]]> 2021-11-30 02:29:37 UTC https://padlet.com/mrrahull/QuriosityP3P4/wish/1919400115 MrRahull https://padlet.com/mrrahull/QuriosityP3P4/wish/1919491327 The simple differences are:

1) Bacteria can only be seen using a microscope while fungi can be seen with the naked eye.
2) Fungi reproduce by spores while Bacteria do not reproduce by spores.

Read the following for more information:

The biggest difference is that fungi are usually multicellular (made up of many cells) while bacteria are unicellular (made of single cells). Fungi more complex living things compared to bacteria. There are many more differences between them, in how they reproduce, eat and live.

Bacteria do not have a cell nucleus while Fungi have a cell nucleus. ]]> 2021-11-30 03:29:23 UTC https://padlet.com/mrrahull/QuriosityP3P4/wish/1919491327 MrRahull https://padlet.com/mrrahull/QuriosityP3P4/wish/1919494004 Pelagibacter ubique is one of the smallest known free-living bacteria, with a length of 370 to 890 nm and an average cell diameter of 120 to 200 nm.

Reptiles today are cold-blooded while dinosaurs were believed to be warm blooded.
