Answer:
In compare to eukaryotes,prokaryotes are morphologically simpler,more evolutionary primitive,less sensitive to physical environment.
Explanation:
Prokaryotes are unicellular organism which don't possess cell organelle like nucleus,mitochondria,Endoplasmic reticulum,golgi body, etc.
They are the first living organism in the primitive earth and the genetic components are located in the cytoplasm which is enclosed by cell membrane.
prokaryotes contain 3 domains that are Archaea, bacteria and eukarya.
The cytoplasm is enclosed by cell membrane.
Molecular studies have reveal that eukaryotes are evolved from prokaryotes.
Some prokaryotes bear long projection which helps them for locomotion,called as flagellum.This is present in gram positive and gram negative bacteria.
Answer:
The role of carbon in biological systems is to allow the formation of organic molecules, in addition to providing energy for living beings.
Explanation:
Carbon is the fourth most abundant element on earth and one of the main elements of the viological systems, and its presence is essential for life on the planet to be maintained.
Carbon is necessary for all living beings, without exception. This is because it is used in the construction of organic molecules without which no living thing can survive, in addition to providing energy when it participates in sugar molecules, such as carbohydrates.

Mosquitos are an example of organisms with r-reproduction strategy. This means that they tend to overproduce, have many offspring , but do not provide care for them. This happens because those organisms live in unstable, unpredictable environments, so rapid reproducing is very important. R strategy helps them produce a huge number of offspring, because at least some of them will survive to reproduce.
Elephants are an example of organisms with k-reproduction strategy, meaning that they have few offspring at a time, take care of them and have a long live span. These organisms occupy more stable environments, usually are stronger, better protected and more energy efficient. Their reproductive strategy is to grow slowly and to produce offspring with high probability of survival.
You would call an 'essay' a serious or witty composition meant to briefly express ideas, views, feelings, or reactions to situations in life. This will make the correct answer C.
