Answer:
Geologists can determine the age of an rock by studying it. However biologists study the evolution of fossils.
Explanation:
Geologists can determine the age of the Earth by studying the rocks and how long it took / takes them to form. Some similarities in their way of studying the Earth are the study of fossils. Both geologists and biologists study the evolution of fossils.
further information:
Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. ... Geologists conduct studies that locate rocks that contain important metals, plan the mines that produce them and the methods used to remove the metals from the rocks.
Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies--human medical research, plant research, animal research, environmental system research--at the cellular level or the ecosystem level or anywhere in between. ... Biologists generally love what they do.
in conclusion, geologists are able to tell a rocks age by studying it but biologists can only study the age of fossils

<span>A photon of UV light causes mutations in the double-stranded DNA via a photochemical reaction. The product of such photochemical reaction in DNA is a cyclobutane pyrimidine dimer. Dimers may be repaired by mechanisms of photoreactivation or nucleotide excision repair (NER), but if the repair doesn’t occur dimers are mutagenic.
</span> <span>
UV light is absorbed by a double bond in pyrimidine bases (thymine and cytosine in DNA). The bond is opened and UV-modified base can now react with neighbouring molecules. If neighbouring molecule is another pyrimidine base, the UV-modified base forms direct covalent bonds with it. A cyclic ring (cyclobutane), not normally found in DNA, is formed (links the two pyrimidines). Next step is forming a single bond between two carbon atoms on the rings.The product of this reaction is a 6-4 molecule pyrimidine-pyrimidone which is more mutagenic than cyclobutane pyrimidine dimers.</span>
Answer:
The probability of an individual in a randomly mating population of having the genotype A1B2|A2B1 = 0.658 = 65.8% ≅ 66%
Explanation:
Due to technical problems, you will find the complete explanation in the attached file
Cellular Respiration occurs in 4 major stages: Glycolysis, NADH
degeneration, Citric acid (or Kreb's) cycle and Electron Transport
Chain. Glycolysis occurs in the cytosol or cytoplasm of the cell. If
oxygen is present, then the next three stages would occur, otherwise
lactic acid or alcohol fermentation would occur. NADH degenration and
Citric acid cycle occur in the matrix of the mitochondria while Electron
Transport Chain occurs in the intermembranal space of the mitochondria.
Most of cell respiration occurs in the mitochondria though. Hope this
helped!
I must say this is a very complete answer but if i might
add,of every part of a cell involved in cellular respiration,the only
organelle is the mitochondria meaning that is the answer.
