Explanation:
DNA can be extracted by grinding the tissue in dry ice or liquid nitrogen with the mortar and pestel or a food grinder. the cell membrane must be disrupted,so that the DNA is released into extraction buffer.
Answer:
Erythema nodosum is characterized by tender, red bumps, usually found symmetrically on the shins. Up to 55 percent of cases have no clear identifiable cause. Sometimes, erythema nodosum is not a separate disease. Rather, it is a sign of some other infection, disease, or of a sensitivity to a drug.
The answer is adhesion- since water molecules have an electrical charge, they are also attracted to any other substance that has any hint of electrical charge. A surface covered in condensation, like a spiderweb with dew droplets, is adhesion at work. Hope this helps :33
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
The number of genetically unique gametes that can be produced by an organism where 2n = 20 cell is 40.
The reason is that there are 20 cells in the organism, so there are 20 possible ways for them to arrange themselves.
For example, if you have two identical cells and a third cell that is not identical to either one, then the total number of potential arrangements is (3 + 1) = 4. This means that there are 24 viable arrangements for three cells to form a diploid organism with two sets of chromosomes.
However, if you have only two cells and no other cells, then there are only 10 viable arrangements: 2 identical and 8 different non-identical combinations.
