Mistakes can happen during DNA replication, and if they are not repaired it can result in a mutation. Certain mutations can lead

to diseases like cancer. What is a mutation and what are the DNA repair mechanisms cells have? Describe one of them.

Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur

m_a_m_a [10]

Answer:

Ca2+ channels closed, Ca2+ pumps operating slowly: a, c, f

Ca2+ channels open: b, e, h

Ca2+ channels closed, Ca2+ pumps operating rapidly: d, g

Explanation:

Experimental technique: Tracking cytoplasmic Ca2+ distribution after a sperm enters the egg Based on what they knew about the fertilization envelope (a protective layer that forms around the egg when a sperm fuses with it), Steinhardt, Shatten, and their colleagues hypothesized that changes in the distribution of Ca2+ ions in sea urchin eggs are involved in the formation of the fertilization envelope. In sea urchin eggs (as in most eukaryotic cells) the concentration of Ca2+ ions is much higher in the endoplasmic reticulum (ER) than in the cytoplasm. To see how cytoplasmic Ca2+ concentration changes in the egg during fertilization, the researchers injected a Ca2+-specific fluorescent dye into the cytoplasm of unfertilized eggs. After adding sperm to the eggs, they observed the eggs with a fluorescence microscope. The following images show the changes in fluorescence that occurred after a single sperm entered the egg. The fluorescence of the dye increased with increasing cytoplasmic Ca2+ concentration. The green color indicates the region of the cell with the highest fluorescence at that point in time.

Sort the labeled regions of the fertilized egg above based on the status of the ER Ca2+ channels and Ca2+ pumps in that region.

Check the diagram attached.It includes the labeled region
