Answer:
DNA molecular weight standard controls, also known as DNA ladders
Explanation:
A DNA ladder is a molecular-weight size marker used to identify the size of the PCR products in a gel electrophoresis. The DNA ladder consists of a solution containing double-stranded DNA fragments with different molecular weights including, among others, 50 base pairs (bp), 100 bp, 1000 bp and 3000 bp DNA fragments. The concentration of each DNA fragment in the DNA ladder must be sufficiently high to be visualized on the electrophoresis gel.
Answer:
I propose that this fungus somehow kills bacteria
Explanation:
you rule out 2,3 because a hypotheses has not yet been proven therefore it is not certain
while in 1 in some cases the bacteria can also over power and kill the fungi using genes
but I chose 4 since fungi lack chloroplasts so they feed of ready made food and bacteria can be autotrophic therefore can manufacture food and so the fungi digests the bacteria in the process of trying to acquire the food since they don't have cell walls I guess
There are 4 states of matter : plasma, liquid, gas and solid.
