Answer:
D. determine the probability of traits
Cells must move materials through the {membrane} and throughout the {cytoplasm} to maintain {homeostasis} Movement of substances is regulated because membranes are {semi} permeable. Membranes are {phospholipid} bilayers that contain embedded {proteins} The cells external environment and cytoplasm are aqueous, meaning that solutes such as {salt}are dissolved in a solvent called {water} Water may travel slowly through the membrane by {osmosis} or quickly through protein channels called {aquaporins}
Hii!!
The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres
2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)
3) Anaphase: sister chromatids are pulled to opposite poles of the cell
4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin
● The order of the stages of mitosis can be remembered using the mnemonic PMAT.
Hope this helps!! if it has pls mark me as the brainliest Xd :D
