Fossil record evidence of evolution shows how organisms change over time.

B. It shows how organisms change over time.

<u>Explanation</u>:                                                                                                                                       Fossil fuels provides the evidence for long term evolutionary changes, documenting the past existence of species that are now extinct. It is Darwin theory of evolution; evidence of early signs of life comes from fossils.

By studying the fossils, scientist can learn how much organisms have changed its life development on earth. There are gap in the fossil record because many early form of life are soft bodied.

The fossil recorded that the organisms die, sometimes the remains are kept as fossil, by determine the age of the fossil provides the data of the organisms .

Where in the cell cycle does the type of mutation in chromosomal translocation occur?
Makovka662 [10]

During metaphase 1 of meiosis of the cell cycle chromosomal translocation occur.

Explanation:

Chromosomal translocation is abnormal phenomenon when a fragment of chromosomes detaches and gets stick to the non-homologous chromosome in an individual. These are causative of aneuploid, cancer and infertility in organism.

In metaphase 1 of meiosis the chromosomes gets aligned on the metaphase plate. This leads to surety of equal number of chromosome in the cell.

Chromosomal translocation are seen in metaphase 1 because it is the phase of rearrangement of chromosomes where fragments easily gets attach to the other chromosome.

Which of the following is correct? Which of the following is correct? Most of the ATP are produced by substrate-level phosphoryl
Nezavi [6.7K]

Answer:

Each FADH2 yields about 1.5 ATP via oxidative phosphorylation.

Explanation:

Most of the ATP molecules are produced by oxidative phosphorylation, not by substrate-level phosphorylation. During glycolysis, 2 ATP molecules per glucose are produced by substrate-level phosphorylation. Similarly, Kreb's cycle also yields 2 ATP per glucose by substrate-level phosphorylation.

For each pair of electrons transferred to O2 from FADH2 via electron transport chain, 4 and 2 protons are pumped from matrix towards the intermembrane space by complex III and complex IV respectively. It generates the proton concentration gradient required to drive the synthesis of 1.5 ATP molecules. Since oxidation of FADH2 is coupled to the phosphorylation of ADP to form ATP, the process is called oxidative phosphorylation.
