Answer:

It travels 4m/s = 14,4km/h

Explanation:

to determinate velocity, you can use the formula v=deltadistance/deltatime

=> v=20m/5s=4m/s

It does not matter which way he is going.

The alkanes in petroleum can be partly separated by
Arte-miy333 [17]

Fractional distillation is the process in which the alkanes in petroleum can be partly separated. This is due to the petroleum having different boiling points. The process starts off with the heating of crude oil for it to vaporize. The vaporized crude oil is then fed into the bottom of the distillation tower. The resulting vapor rises through a vertical column. As the gases rises through the distillation tower, its temperature decreases. Thus, certain hydrocarbons begin to condense and run off at varying levels. Each level-specific condensed fraction contains hydrocarbon molecules that has a similar number of carbon atoms. These "cuts" of boiling point allow numerous hydrocarbons to be separated out in a single process. The cooling of the tower height allows for the separation. Subsequent to the refinement, individual fuels may undergo more refinement to remove existing contaminants or substances so as to improve the quality of the fuel through cracking.

If a fossil contains 50% of the amount of carbon that a living animal contains, how many half lives have passed while it decayed
vekshin1

The currently accepted value for the half-life of 14C is 5,730 years. This means that after 5,730 years, only half of the initial 14C will remain; a quarter will remain after 11,460 years; an eighth after 17,190 years; and so on.

Can someone please help me with #22 I would appreciate it. <br> Thanks

Answer:

Glycolysis occurs in the Cytoplasm

Electron Transport Chain occurs in the Mitchondria

Krebs Cycle also occurs in the mitchondria

Explanation:

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Nearly all living organisms carry out glycolysis as part of their metabolism. The process does not use oxygen and is therefore anaerobic. Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells.

The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria. NADH  hydrogen ions and electrons into the transport chain.

The Krebs cycle happens only within the mitochondrial matrix. Pyruvate is formed in the cytosol of the cell, then imported into the mitochondria.
