Answer: Starch (made by plants) and glycogen (made by animals) are both polysaccharides made up entirely of glucose subunits. Starch and glycogen function as storage polysaccharides, because excess fuel (glucose) is stored within the polysaccharide for later use as fuel.
Explanation:
1.) It is essential to use many different types of equipment because you want to know what you are seeing and with this equipment you can you also want to make the right obversions like how bright or big a star is.
2.) The missing element would be oxygen. Since earth has carbon and oxygen it makes carbon dioxide so if a different planted has oxygen it will make it so people could breath on it.
hope i helped
Answer:
The correct answers are: Dilution factor = 250 and concentration of DNA in undiluted sample = 2.5 μg/μl.
Explanation:
- Volume of DNA taken = 2 μl.
- Volume of added water = 498 μl.
- Total volume of the sample = 2 μl + 498 μl = 500 μl.
- Dilution factor =
- A₂₆₀ of the given sample is = 0.2.
- We know that 50 μg/ml concentration of pure double stranded DNA gives an absorbance, A₂₆₀ = 1.
- Again, Concentration of DNA(µg/ml) = µg/ml.
- = μg/ml.
- In order to convert it into μg/μl, we have to divide the above value by 1000, hence we get, μg/μl.
Chromatin
Chromosome, the highest packing level of DNA, is packed in nucleus. DNA strand itself is packed in chromatin. Chromatin is DNA packaging into 30nm fibers that involve DNA strand with scaffolding around DNA proteins, like histones, in eukaryotic cells’ nucleus.
Explanation:
The DNA strand is folded into nucleosomes, bead-like structures on the DNA and fold up into the 30nm fibers. During meiosis and mitosis, the chromatin is super-coiled up into thicker fibers called chromosomes. Chromosomes within the nucleus can be viewed by a light microscope in a cell in metaphase.
