Occurs when a new organism is formed from the same organism
The formation of a new organism is a result of evolution via genetic mutation
The number of cells in an organism constantly changes. Cells die and are replaced by new cells all the time. As I type, cells on my fingertips die, fall off and new cells replace them. There are far too many cells to count in any organism, and they are constantly changing. Here's an interesting fact- if one of the cells on the tip of your nose was the size of a football pitch, your head would be the same size (roughly) as the world!
The head of the spermatozoa buries itself in the egg and the tail drops off. At the exact same moment the surface of the egg changes to prevent any other sperm from entering it. The coating of the head of the sperm then opens and the DNA is released and the egg becomes like a new cell with a new set of DNA in addition to its own. The egg then begins to split and split again, and again and again until a human is created.
No, scientific theories change all the time as new observations present new data, new theories are formed to explain the observations and are checked to see if they predict correctly the outcome of new experiments.The scientific method remains the same.
i am doing the same worksheet right now.... Molecule
Magma is formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantel rock.
a mixed compound accours when new compounds are formed
Fragmentation occurs when an organism of many cells breaks into two or more parts and these parts survive to produce a new organism.
A new substance is formed only after a chemical change.
the colour,appearanceand composition changes.
Budding is a form of reproduction. It is asexual reproduction that occurs when a cell divides at a certain place. The result is a bud, or growth, from this bud a new organism is formed.
