Is the treatment being compared to the control in the experiment?
Nov 29, 2018 · 1 BioWizard The correct answer is: the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor . It has been shown that treatment with injected umbilical cord stem cells has strong therapeutic effects on glioma models.

The treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, …
What does the distribution of cells in the treated sample tell you?
Jan 21, 2020 · b) A good experiment must have an experimental group. A control group may be useful but is not critical. c) A good experiment should include a potentially confounding factor in at least one group. d) A good experiment includes replication by applying treatments to multiple experimental units. I need help with 3,4,5.
What treatment is being compared to control in the experiment?
The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment).Jul 3, 2020
Which is the best explanation of how the activity of a cell is controlled quizlet?
Which is the best explanation of how the activities of a cell are controlled? The activities of a cell are under the control of the cell's DNA, which contains the instructions for the cell.
Which experiment would best determine if the green anole lizards diet was affected by their change in habitat?
Which experiment would best determine if the green anole lizards' diet was affected by their change in habitat? Yoel should compare the diet of green anole lizards from islands where no brown anole lizards live to the diet of green anole lizards from islands where green and brown anole lizards live.
How does Taxol stop cell division mastering biology?
Taxol is an anticancer drug extracted from the Pacific yew tree. In animal cells, Taxol disrupts microtubule formation. Surprisingly, this stops mitosis.Jun 10, 2013
Which is the best explanation of how the activity of a cell is controlled?
Which is the best explanation of how the activities of a cell are controlled? a. The activities of a cell are controlled by the environment in which the cell develops. External signals direct every action of the cell.
What is the disease that occurs with the loss of control of the cell cycle?
Cancer is a disease that can occur when control of the cell cycle is lost.
Which of the following traits helps to differentiate the different species of anole lizards?
Differences in leg length, body size, body color, and dewlap size and color distinguish different species of anoles.
Which of the following description constitutes a controlled experiment?
What is a controlled experiment? This is when a hypothesis is scientifically tested. In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled.
What does the evidence suggest regarding the evolution of body types of anole lizards on the different islands?
DNA evidence suggests that the different lizard body types (twig, grass, etc.) evolved independently on each of the four large Caribbean islands. An anole lizard with a light-colored dewlap will develop a darker dewlap that stands out better in a bright environment.
Which statement best describes the difference S in the distribution of cells in the treated sample compared to the control sample?
Which statement best describes the difference(s) in the distribution of cells in the treated sample compared to the control sample? The treated cells are mostly in the G1 phase (region A), but in the control sample, there are peaks of cells in both G1 and G2 (region C).
How do cells become differentiated mastering biology?
How do cells become differentiated? Different genes are expressed so that different proteins are produced. The DNA in each cell changes so that the appropriate proteins are produced. Paternal effect genes begin the process of differentiation by providing positional information.
Why do some species employ both mitosis and meiosis whereas other species?
Why do some species employ both mitosis and meiosis, whereas other species use only mitosis? They need both if they are producing animal gametes. *The form of cell division that produces animal gametes is meiosis, not mitosis. The production of gametes in plants is a function of both mitosis and meiosis.
What is the cell cycle?
The cell cycle represents the coordinated sequence of events in the life of a cell from its formation to its division into two daughter cells. Most of the key events of the cell cycle are restricted to a specific time within the cycle. In this exercise, you will identify when various events occur during the cell cycle.
How does mitosis unfold?
Mitosis unfolds through a sequence of stages marked by specific events in the cell. The structural changes in the cell are brought about by a series of tightly coordinated underlying mechanisms. Sort each process into the appropriate bin to indicate the stage of mitosis in which it occurs.
How is cytokinesis accomplished in animal cells?
Cytokinesis in animal cells is accomplished by constriction of the cell along the plane of cell division (formation of a cleavage furrow). In plant cells, which have cell walls, a completely different mechanism of cytokinesis has evolved.
Answer
The correct answer is: the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor .

What is the name of the drug that is used to treat cancer?
This cell is most likely. a plant cell in the process of cytokinesis. Vinblastine is a standard chemotherapeutic drug used to treat cancer.

Do bacteria have chromosomes?
Structurally, bacterial cells contain a single chromosome that is much shorter than those in eukaryotic cells, and bacterial cells lack a mitotic spindle.
