Answer:
I would say We don't have enough evidence or Cell theory is still changing.
Explanation:
There are so many cells in everything so it's almost impossible to know exactly what is going on. Theories about cells have been going on for over 500 years, and we still don't know exactly what is what.
Answer:
1. Thin Humus layer, minerals deep beneath the surface
2.Solar energy
Explanation:
I just took the test and got it right.
Answer:
The cells of living things are made mainly of four elements: carbon, hydrogen, oxygen and nitrogen. They make up 96% of the atoms that are in living things, so they would be considered major chemicals. However, depending on how you define major, other elements that only make up a few percent of cells can top the list.
Explanation:
B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.
Explanation:
The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.
According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
