Damaged cells of an organism are usually by mitosis?
Replaced.
Why would a change in DNA sequence change that organism?
In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism In an organism, a genetic code is made by the cells, but in that genetic sequence, if one or more letters are change, replaced, or deleted, then those cause mutations in the organism
Is petrified wood abiotic or biotic?
Wood is biotic because trees are living so is wood -lexie bryson three ocks middle school
Is a mutation more dangerous in a cell undergoing mitosis or meiosis?
Meiosis, because it occurs in gametes, which produce a new organism, rather than mitosis, which occurs in cells other than sex cells, and usually just causes the cell to die, and be replaced rather than grow into a mutated organism.
What is the term for moving fragments of DNA from one organism to another?
The term is transgenesis.The product is recombinant DNA, and the resulting organism is transgenic, e.g. a transgenic mouse. But the word "transgenic" is not applied to bacteria.Typical methods of creating recombinant DNA include:* using bacterial plasmids, which are modified and then replaced in bacteria * using a virus as a vector (carrier of modified DNA into a host organism) * microinjection using a micropipette There are other techniques.
What is the answer to this describes a organism whose tissues are completely replaced by minerals?
An organism whose tissues are completely replaced by minerals is a fossil.
What is an organism's organic tissue most likely replaced with when an organism is petrified?
When an organism is petrified its organic tissue is most likely replaced with minerals.
What is an exact copy of an original organism in which the hard parts have been penetrated and replaced by minerals?
A fossil.
How does a organism become petrified?
The cell contents are replaced over a long period of time by minerals.
What is an example of petritrified?
Petritrified Fossil- a fossil formed when minerals replaced all or part of an organism.
How does fossilisation protect somthing?
During fossilisation, living cells are replaced by minerals. This preserves the physical appearance (but not the original organism)
When the remains of an organism are replaced by minerals.?
In geology, petrification or petrification is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals. So yeah the answer is petrification
What is the difference between petrifaction and permineralization?
Permineralization is the process of fossilization where mainly water mineral deposits take the form of the organism. The minerals harden with time and pressure from over laying deposits turning into rock. Petrification happens when silica binds with celulose of a plant and turns into stone often retaining the microstructure of the plant.
Properties of components are replaced by new properties are a mixture or a compound?
When the properties of components are replaced by new properties they form a compound and not a mixture. Mixture retain their individual properties in variable proportions.Ê
Damaged cells of an organism are usually by mitosis?
Replaced.
What can animals not be preserved in as fossils?
Animals are not preserved as fossils. Fossils are imprints of the organism where the body has been replaced by rock minerals. They are most usually found in sedimentary rocks, occasionally in metamorphic rock but never in igneous rock.
How are permineralization and replacement similar?
Minerals such as silca, iron, and pyrite are critical for fossilization in both processes. However, in replacement, the hard structures of the organism dissolve and are replaced with minerals. During replacement, the original microscopic details, such as the inside of a bone, are partially or totally destroyed. ~Follow me on Twitter: @jennholguinxo I follow back!
