When the cells grows , or increases in size, it might reach, say, double (x2) it's original size, the cell then divides in half (x.5) and returns to it's original size. To show this mathematically.... e.g. original size = 10 units original size x 2 = 10 x 2 = 20 the cell divides so, 20 x .5 = 10 back to the original size, the 2 cells then grow and when they become double the size they divide leaving 4 cells, they grow and so on...
Think of it like Play-Doh.When you take a large lump, split it in two, and again, and again, you have eight "cells", except since cells don't shrink when they multiply, but grow another one, you will then go from one cell, to eight cells of the same size.
when the cells increases: these are examples
When the cells grows , or increases in size, it might reach, say, double (x2) it's original size, the cell then divides in half (x.5) and returns to it's original size. To show this mathematically....
e.g.
original size = 10 units
original size x 2
= 10 x 2
= 20
the cell divides so,
20 x .5
= 10
back to the original size, the 2 cells then grow and when they become double the size they divide leaving 4 cells, they grow and so on...
When it decreases:
the cell divides and it replace, and add new cells from the old cells to create a new and a healthy cell and to prevent cell loss..............''<.....>''
Cell division has three ways it prevents problems in cell growth. The three ways are as follows: when cells increase, when cells decrease, and preventing cell loss.
When a cell becomes to large it begins to pull apart so that it can reproduce. It goes through many phases: Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
They stop producing protein.
Cell division has three purposes for the organism. The are responsible for the reproduction, growth and maintenance of both single celled and multicellular organisms.
Three sources of signals related to the regulation of cell growth and division are growth factors, hormone signals, and signals from neighboring cells. Growth factors are molecules released by cells that promote cell proliferation. Hormone signals, such as those from the reproductive system, can also influence cell growth and division. Signals from neighboring cells, called contact inhibition, can regulate cell growth by preventing cells from dividing when they come into contact with other cells.
Cells must reproduce for growth, development, and repair.
Interphase{G1 (cell growth), S (DNA is copied), G2 (growth and preparation for cell division)}, Cell Division {mitosis and cytokinesis} False
- interphase - mitosis - cytokinesis
The three terms of a division problem is dividend, divisor, and quotient.
The three functions of cell division are reproduction, growth, and repair
growth developement and repair
is jopay cute
that you can score three points in one shot
excretion, cell division, growth
So the problem is: Solve: 4x2 - x = 3
per
The first number is called the dividend. The second number is called the divisor. The answer is called the quotient.
Cell division has three purposes for the organism. The are responsible for the reproduction, growth and maintenance of both single celled and multicellular organisms.
