Though the lockdown has undoubtedly had somewhat of a negative impact on certain acpects of our society, there’s no denying that our environment has seen certain benefits since we’ve tucked ourselves away in our homes. According to the Earth Observatory at NASA, satellites have detected decreased levels of air pollution as well as carbon monoxide emission. This is attributed to the closure of most industries as well as the lack of cars and other transportation on the road. Though it isn’t just the air we’re beginning to notice changes in- for the first time in a very long time, the canals in Venice are crystal clear. With fewer boats and tourists about, the water is free of pollution for the first time in centuries. With these facts in mind, I can safely say that I believe the lockdown has definitely positively benefited the environment, but it’s up to us to keep it that way once it ends.
The symbiotic relationship between fungi and algae is lichen. Brainliest please :)
Answer:
A living being or organism is a complex set of organizational material, in which molecular communication systems intervene that relate it internally and with the environment in an exchange of matter and energy in an orderly manner, having the ability to perform the basic functions of life that are nutrition, relationship and reproduction, in such a way that living beings work by themselves without losing their structural level until their death.
Explanation:
The matter that composes living beings is formed in 95% by four elements (bioelements) that are carbon, hydrogen, oxygen and nitrogen, from which biomolecules are formed: 3 4
Organic biomolecules or immediate principles: carbohydrates, lipids, proteins and nucleic acids.
Inorganic biomolecules: water, mineral salts and gases.
These molecules are constantly repeated in all living beings, so the origin of life comes from a common ancestor, as it would be very unlikely that two living beings with the same organic molecules have independently appeared.5 6 Stromatolites have been found 3700 million years old, 7 so that life could have arisen on Earth 4100-3800 million years ago.1 8 9
All living things are made up of cells. Inside these are carried out the sequences of chemical reactions, catalyzed by enzymes, necessary for life.
The science that studies living things is biology.
I believe it would be determining the true age if rock layers. Hope this helps :)
