What describes the specific job that something does?

What describes how body cells grow and reproduce?

Flagella
______ refers to the parts of an object and how the parts are put together?
Structure
The daughter cells are called ______

What cells can divide and become whatever kind of cells the body needs?
stem cells
How are unicellular and multicellular organisms different
Unicellular organisms have one cell but multicellular organisms have two.
what are three things that plant cells and animal cells have in common
nucleus, mitochondrion, and cell membrane
What is the function of the stem cell and why is it important?
Th stem cell can develop and the new cells can come in and help. They are important because they can give the body any cell it needs when it is sick and replace damaged cells.
How is mitosis different from cytokinesis?
Mitosis how body cells reproduce and grow. cytokinesis is the dividing of the cytoplasm of the cell which makes daughter cells.
Give two examples of how organisms obtain the energy they need to stay alive?
They use clean air and water and materials to build there homes.
identify characteristics of living things?
Uses resources, is made up of cells, grows and develops, responds to stimuli.
How do cells differ?
bye being different they work different jobs like how flagella are found in animal and plant cells and cilia traps dust and particles and keeps mucus away from lungs.
Describe examples of specialized cells?
Muscle cells, nerve cells, and blood cells
Describe the process of mitosis?
The chromosomes copy themselves. Then the chromosomes become a x shape which is a copy of each other. Next they line up in the middle. After that the fibers pull apart the duplicated chromosomes. Then a nucleus forms around each chromosomes Finally cytoplasm creates a new cell that is identical to the first one.
Describe the process of meiosis?
First the chromosomes are copied. Then they line up and exchange DNA. After that the chromosomes separate into pairs with a x shape chromosomes in each 2 pairs. Then the nucleus breaks down and the chromosomes line up in the center of the cell. the network of fibers forms and attaches the chromosomes Then the strands pull away from each other. Finally a new nucleas forms which means there are 4 cells now.
What percentage of a cell is water?
70% of water.
What does DNA stand for?
deoxyribonucleic acid
What is a nerve cell
neurons
How many chromosomes does a human child child have?
46 chromosomes
How many chromosomes does a human pair have?
23 pairs
