An embryonic stem cell is pluripotent, adult stem cells are multipotent while skin cells are determined cells. Pluripotent means that the cells can differentiate into any cell type that makes up the organism while multipotent means that the stem cell can differentiate into  a limited number of cell types. A determined cell is that which is already differentiated.

Why is the microscope important to the study of microlife?
Sophie [7]
Wait this is highschool biology?! 
Woah... thought it would be harder....


Anyways, see "micro" means really small, so small that your bare eyesight can't take it (or see it, I don't care). A microscope was meant to see things that our eyes can't. Since humans cant see microlife we use a microscope.

How is loss of biodiversity connected to extinction of organisms?
Mariana [72]

Answer:

In an ecosystem, everything is connected. All ecosystems have some form of food chain and symbiosis. This means that animals rely on each other for life. If one animal were to die then others would be negatively affected. Overall, this means that when biodiversity is lost it becomes harder for organisms to survive. For example, pandas rely on bamboo to survive. So, when it gets cut down and destroyed the pandas also suffer. Additionally, in ecosystems, a wide variety of organisms helps other living creates have more forms of survival. This shows how important biodiversity is.

Describe the relationship between proteins and nucleic acid
Dmitry [639]

Answer:

Explanation:

Proteins and Nucleic Acids are not similar in structure. They look nothing alike, either as large molecules or in terms of their building blocks. While they're both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways. The major relationship between the two has to do with protein production -- DNA contains the information that a cell uses, with the help of RNA, to make protein.
