Answer: Heat and pressure compress the mud and carbon over millions of years, forming sedimentary rock such as shale. ... The heated rock recombines into silicate minerals, releasing carbon dioxide. When volcanoes erupt, they vent the gas to the atmosphere and cover the land with fresh silicate rock to begin the cycle again.
Explanation:
One molecule of glucose is broken down into two molecules of pyruvate.
So the krebs cycle occurs twice for each glucose molecule.
In the krebs cycle 1 molecule of FADH2 is produced.
we multiply 3 molecules of glucose by 2 krebs cycles that occur
3*6=6krebs cycles
and 1 molecule ofFADH2 per cycle so we get 6 molecules of FADH2
Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)
In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.
The correct answer is choice A - Isogametes.
Unicellular organisms would most likely have isogametes because they are the simplest form of sexual reproductive cells. They do not exhibit any differences in form, size, structure, or sex. In line with this, unicellular organisms are the simplest form of living organisms.
