question
How many different types of cells are in the human body? 5 ex.
answer
Over 200 different type of cells. ex: skin cells, muscle cells, neurons, stomach cells ,plateletes
question
Explain differentiation. How can cells perform different functions when they all have the exact same dna
answer
Differentiation is the process by which basic cells become more specialized to perform a specific function. Cells can perform different functions even if they have the exact same DNA by only using the instructions that are needed depending on their function.
question
How do cell differentiation and cell division work together?
answer
Cell differentiation and cell division both work together by starting out with a somatic cell(basic cell) and cell differentiation gives it the specific instructions in the DNA to enable it to perform its function, then cell division comes in also known as mitosis, and it makes the cell with the whole package included with its function
question
What are three circumstances where mitosis or cell division will occur?
answer
Growth and development, regeneration and replacement
question
Do you think that cell types with shorter or longer life spans go through mitosis more often? explain your answer.
answer
cell types with shorter life spans go through mitosis more often because every time a cell dies it needs to be replaced.

Replacement
answer
different cell types have different life spans. When a cell dies it must be replaced.

question
Regeneration
answer
In some multicellular organisms, limbs or bodys parts can be regenrated through mitosis.

question
mitosis
answer
A cell splits into 2 and both cells that are created are identicall meaning they have the exact same DNA

Question
What is the right structure for an essay
Answer
A paragraph is a related group of sentences that develops one main idea. Each paragraph in the body of the essay should contain:
  • a topic sentence that states the main or controlling idea
  • supporting sentences to explain and develop the point you’re making
  • evidence from your reading or an example from the subject area that supports your point
  • analysis of the implication/significance/impact of the evidence finished off with a critical conclusion you have drawn from the evidence.
