All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.

The very first microscope was made by Robert Hooke and was a simple looking microscope. It has been many years since then and technology has evolved more and more. Modern microscopes can see things so small they’re invisible to the human eye.
The study of cells will have evolved as well, with scientists discovering something new everyday that will go in future textbooks for future generations to learn.
The impact of the modern day microscope has helped so much with the study of cells.
Answer:
412.5 Parts per million.
Explanation:
Based on preliminary analysis the global average atmospheric carbon dioxide in 2020 was 41 2.5 parts per million setting a new record high amount despite the economic slowdown.
Answer:
Because they are yet to perform photosynthesis, which requires sunlight
Explanation:
The leaves of plants are the site of a unique process called PHOTOSYNTHESIS. Photosynthesis is the process by which plants synthesize their food in form of glucose in the presence of sunlight. The glucose they synthesize is however, stored as STARCH (a carbohydrate polymer) in the leaves. This is why the leaves of a plant will naturally test positive for starch at certain times.
However, the leaves of plants will not test positive for starch early in the morning but do so at the end of the day because the leaves of that particular plant is YET to undergo photosynthesis due to lack of light from sun. However, at the end of the day, it would have performed photosynthesis and synthesize sugar and hence, test positive.
