Yes. it provides energy for the rest of the cell by creating energy from nutrients.
Answer:
1 A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus.
2 Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
3 Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
4 The plasma membrane.
Cytoplasm.
Ribosomes.
Genetic material (DNA and RNA)
5 Prokaryotes
Answer: Vestigial organ
Explanation:
Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.
The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.
In a research, the independent variable is the one which causes a change in the dependent variable. In this case, the nurse visit in hoped to cause reduction of doctor visits. That means the doctor visit is dependent variable and nurse visit will be the independent variable<span>.</span>
