<span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.

Answer:
I chose nucleus and the mitochondria
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
Have a great day! :)
Answer:
There are 83.82 centimeters in 33 inches.
Explanation:
A similar question was asked online, here is the answer it gave:
'“Negative control” is a treatment that by definition is expected not to have any effect (neither positive effect, nor negative effect). “Positive control” is treatment with a well-known chemical that is known to produce the expected effect with the assay that you are studying. Application of an antagonist is not a negative control in your case. “Negative control” is condition that should be treated with the same solutions or buffers as your “treatment” condition, with the only difference that instead of the chemical that you investigate you should add just the solvent that was used to dissolve you chemical in the respective final concentration that you have in the “experimental treatment” condition. For example if your chemical is dissolved in DMSO – than the correct negative control will be to add to the medium/buffer just DMSO in the same final concentration that you reach with your “treatment” condition. One of the reasons of using such negative control is to verify that the solvent is having no effect in your assay. Note that among all treatment conditions (“negative control”, “positive control”, “experimental treatment you are investigating”) the volumes and the composition of the treatments that you are doing should be uniform: always treat with the same volume of medium or buffer, always containing the same concentration of the used solvent (e.g., DMSO). The only difference should be the presence or absence of the defined compound-treatments (agonist, antagonist, the chemical for the experimental investigation etc.).'
My best advice is to use the textbook you have, or use examples of a negative control when testing organic compounds because you have to find something that you can assign, like a worm in a box of dirt, the worm could have enough food to survive, so that is your negative control, but when it comes to finding the best, that would have to rely on something within the parameters of being self sufficient like a plant getting its energy from photosynthesis, etc.
