Answer:
The main organelles of a eukaryotic cell are the Nucleus,endoplasmic reticulum,Golgi apparatus,ribosomes,lysosomes,mitochondria and cytoskeleton
Explanation:
1.Plasma membrane : It is a outer most layer of a cell surrounds the cytoplasm and isolate a cell from its external environment.The internal oganelles of a eukaryotic cell are membrane bounded.
2.Cytoskeleton: It maintains cell shape.It is made up of microtubules,intermediate filaments and microfilaments inside the cytoplasm
3. Nucleus: It contains genetic material DNA which is binds with protein such histones
.The other organelles description is given in the table format.
You did not provide options therefor i can not be exact but the cell membrane and cell walls are what contain the cytoplazm so it would not be ar

Answer:
Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow.

Answer :There was enough oxygen in the atmosphere to support a major burst of life on Earth
Explanation:
The Great Oxygen Event marks the time, approximately 2.5 billion years ago, when there was enough oxygen in the atmosphere to support a major burst of life on Earth
For the first half of the Earht's history, there was no oxygen in the atmosphere. It was inhabited only by single-celled organisms.Of those simple life forms, the cyanobacteria may have. evolved a way to take energy from sunlight, and used it to make sugars out of water and carbon dioxide. They used the same chemical process we know as photosynthesis. This released vast quantities of oxygen into the atmosphere and triggered the evolution of complex life.
