Answer :There was enough oxygen in the atmosphere to support a major burst of life on Earth

Explanation:

The Great Oxygen Event marks the time, approximately 2.5 billion years ago, when there was enough oxygen in the atmosphere to support a major burst of life on Earth

For the first half of the Earht's history, there was no oxygen in the atmosphere. It was inhabited only by single-celled organisms.Of  those simple life forms, the cyanobacteria may have. evolved a way to take energy from sunlight, and used it to make sugars out of water and carbon dioxide. They used the same chemical process we know as photosynthesis. This released vast quantities of oxygen into the atmosphere and  triggered the evolution of complex life.

There are 3 parts of cell theory: all living things are made up of cells, all cells come from pre existing cells, and the cell is the basic unit of life. S<em>ince Schleiden and Schwann’s experiments proved that certain tissues were made up of cells (and those tissues are from living organisms), it most closely relates to the part that all living things are made up of cells.

Identical copies of chromatin held together by cohesin at the centromere are called _____.
Amanda [17]

Answer:

Sister chromatids.

Explanation:

Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.

Consider the atps that can be generated via substrate-level phosphorylation. Will glycolysis be useful for generating any atps d
iris [78.8K]

Indeed, glycolysis would be useful for creating ATP as it produces a net increase of ATPs. One glucose particle produces two ATP in a cycle. On the off chance that the ETPUM experiences the procedure of aging, at that point the natural atoms would then be able to be used as the essential electron transporter. Two ATPs would be delivered by means of TCA cycle and yes it will be sufficient to help development.  

Further Explanation:  

Phosphorylation:  

Phosphorylation is the synthetic expansion of a phosphoryl gathering (PO3-) to a natural atom. The expulsion of a phosphoryl gathering is called dephosphorylation. Both phosphorylation and dephosphorylation are done by catalysts (e.g., kinases, phosphotransferases).  

ATP:  

Adenosine triphosphate is an unpredictable natural synthetic that gives vitality to drive numerous procedures in living cells, for example muscle withdrawal, nerve motivation proliferation, and substance amalgamation. Found in all types of life, ATP is regularly alluded to as the "atomic unit of money" of intracellular vitality move.  

ATP utilized for:  

ATP Molecule. The Adenosine triphosphate (ATP) particle is the nucleotide referred to in organic chemistry as the "atomic cash" of intracellular vitality move; that is,ATP can store and move substance vitality inside cells.  

TCA:  

Tricyclic antidepressants (TCAs) are a class of drugs that are utilized basically as antidepressants. TCAs were found in the mid 1950s and were promoted later in the decade. They are named after their concoction structure, which contains three rings of particles.
