Answer:
100 units
Explanation:
The interphase of the cell cycle includes three stages: G1, S, and G2. During the S phase of interphase, the cell enters the process of DNA replication. DNA replication duplicates the existing DNA molecule and doubles the DNA content of the cell. The cell accommodates the newly formed DNA in two sister chromatids of chromosomes. If a cell of grasshopper contained 200 units of DNA in the G2 phase, the cell would have 100 units of DNA in the G1 phase. The S phase would have doubled the DNA content and the G2 phase had 200 units.
The correct answer for the given question above would be option B. Thale cress <span>is a plant that is genetically engineered with genes that break down toxic materials, so this would be a transgenic type of organism. By definition, transgenic organisms undergone genetic engineering wherein genes of a particular specie is modified or transplanted into another. Hope this helps.</span>
It is best to use regular light microscopes to observe that.
For simple structures, onion cells doesn't require a very large magnification. Magnifications for such as 100X or 150X is already enough to determine the different structures of onion cells such as cell walls or cytoplasm.
It is not very suitable to use a electron microscope especially as high school or college students, as electronic microscopes can be really expensive, usually only top universities have them. Also, it is quite complicated to control the microscope comparing to the common light microscope that we can easily find in many school laboratories. They're easy to function and they're a lot cheaper.
So, it's best advised to use a light microscope, unless if you're really into studying very detailed structures and you're experienced in doing these sorts of things, then you should use a electron microscope.
Answer:
The answer is D. Calcium
Explanation:
The Electrolyte, according to the reference table in the question, which focuses mainly outside the body's cells is Calcium. Calcium has a value of 8 to 10 mEq / l in the extracellular fluid and 0.01 mg in the intracellular fluid. It is an electrolyte with positive charge: Ca ++.
Explanation:
compliment activation is the lysis,(destruction) of bacterial, viral, fungal, through the membrane attack complexes.
