Some trees are cool but not all .why?

* Why? What? How? 🤔

 Question: 

                        It is much colder under some trees. To make   that difference in the shade of the trees?

 Answer: 

                 If there is shade under almost all the trees we get cold feeling in summer. Depending on the size of the leaves on the tree and the thickness of the branches, dense or thin shadows may form. Achieving different levels of cooling under different trees is affected not only by the intensity of the shade but also by how high the leaves of those trees are on our heads and the amount of water received by those trees. If the alleys between the leaves and between the branches are good, the shade intensity will be less and the coolness will be less. If the leaves of the trees are too high on the head, the feeling of coolness will be less due to the hot air around us repeatedly touching us even if the shade is good. The feeling of coolness is better if the height of the trees is low. Finally, let us see how the amount of water supplied to the trees determines the coolness.In summer, each tree tries to save water by reducing the transpiration that normally occurs in its leaves. So that the percentage of moisture in the air beneath them is low. But if water availability is good, evaporation will take place in such leaves and the temperature of their leaves and branches will be . The air blowing over them is also cool and makes us feel comfortable.

* Question: * Can some creatures see colors?

* Answer: 

 We can see the color ... some animals can not see ... even sharks ... New research has revealed!

Imagine for a second you were transposed into the karmic driven world of Earl. The colorful fish swimming in the blue water, the strange plants and the coral islands are all amazing sights. But all these beauties are visible to us. Because some aquatic animals cannot see color. Researchers have recently discovered that sharks are just as good. That means the whole world is like a black and white movie to them.

How do we know that sharks do not see colors? Have you ever wondered if they can open their mouths? Humans and animals have been shown to have retina in their eyes, which are visualized by a system that senses light rays falling on it. There are two main types of light-absorbing cells on the retina. Away rod, cone cells. Rod particles detect differences in the intensity of light and motion of objects, while cone particles display a variety of colors. Scientists can look at the retina of any animal to see if there are any cells and find out what the world looks like to them.

So some scientists have researched about 17 species of sharks in Australia. Ten species have no original cone cells. The rest are homozygous cells of the same type. Based on this they concluded that they could not notice the color differences.

'What do we look like?' Do not expect. Millions of sharks are dying in fish traps around the world. If you know how to look at them, you can make traps and nets that do not attract them. That puts them at risk. As well as their swimwear for diving in the sea can also be designed in a way that does not attract them. Hence the risk to us.

* Dogs and cats do not see red and green colors.

* Cattle such as cows and buffaloes appear all over the world in black and white.

* Many types of fish and birds can see the color.

* Bees can see ultraviolet color which is not even visible to us.

* Ants do not see red.
