Because any other substance couldn't carry the heat and the amount of surface area gives it more of an opportunity to cool down
There would be dead animals overloading the Earth. Think about it, without worms and other things that break down dead things they would still be here and just sit there.
As a result of mitosis, each of your body cells is
c. is genetically identical to all others
Explanation:
During cellular division, the chromosomes, that have already duplicated, condense and fasten to spindle fibers that pull one copy of every body to opposite sides of the cell. The result's 2 genetically identical daughter nuclei. the remainder of the cell might then still divide by organic process to supply 2 daughter cells.
Answer:
The statement that says " The mitochondrion contains a circular chromosome that has bacterial DNA sequences" is true among the all statement given above.
Explanation:
The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory. This theory explains that the aforementioned organelles are formed as they are taken inside in one another by the prokaryotic cell. Some of the evidences in support of this theory are mentioned below:
- Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.
- Ability of these organelles to divide only through binary fission as the bacterial population.
- The associated ribosomes are similar to the bacterial ribosomes.
- Presence of porins in these organelles similar the bacterial membrane.
