A pulmonary embolism is a Non infectious disease
Red blood cell
the biconcave shape helps it to squeeze through blood vessels smaller than itself and not get stuck inside (the lack of nucleus also helps it to do this as it has a smaller volume) and the haemoglobin causes the oxygen to stick to it to be transported to other parts of the body.
If a drought were to occur, an organism who has an adaptation for moisture retainment would be the most likely to survive. This is because they will be able to survive the lack of water during the drought and still stay hydrated.
A good situation similar to this would be succulents in the desert. Each of them have the ability to retain high amounts of water when there is precipitation, which allows them to perform all of their needed functions in order to survive.
I hope I helped!

Because macroevolution is the set of global transformations in the evolution of species according to their genetic patterns and biological behaviors across time and place.</span>
Explanation:
The classical cell theory was proposed by Theodor Schwann in 1839. There are three parts to this theory. The first part states that all organisms are made of cells. The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells. The third part, which asserts that cells come from preexisting cells that have multiplied, was described by Rudolf Virchow in 1858, when he stated omnis cellula e cellula (all cells come from cells).
Since the formation of classical cell theory, technology has improved, allowing for more detailed observations that have led to new discoveries about cells. These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within cells.
