Why do you think Leeuwenhoek named the cells he observed "animalcules"
ra1l [238]

Answer:

Using single-lensed microscopes of his own design and make, Van Leeuwenhoek was the first to observe and to experiment with microbes, which he originally referred to as dierkens, diertgens or diertjes (Dutch for "small animals" [translated into English as animalcules, from Latin animalculum = "tiny animal"]).

Leeuwenhoek named the cells he observed originally as dierkens, which is the Dutch word for small animals, and translated to English as animalcules.

Hope it helps :)

Though I may be wrong :( ...

Have a great day!

The level of oxygen in the air is measured in a garden and on a city road. Which location has a higher level of oxygen and why?
GenaCL600 [577]
I would say the garden has more oxygen. oxygen and carbon dioxide is completely 2 different elements. and since there are more plants, most likely, if it has enough sunlight, the garden will have a better oxygen, because for plant photosynthesis it releases oxygen as their by product.
however please note that if the garden is dark, no light, the garden will lower the oxygen concentration because plants respire and they release carbon dioxide instead. photosynthesis only occurs in light condition as its the source of energy.
