Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
O 2,500 mg
O 250 mg
O 2.5 mg
O 50 mg
To calculate the dosage of a drug given in mg/kg for a person, multiply the dosing rate by the person's mass. In this case, the dosing rate is 50 mg/kg and the mass of the person is 50 kg, yielding a total dosage of 2,500 mg.
When administering a drug with a dosing rate that is given in mg/kg, you need to multiply the dosing rate by the patient's mass to determine the proper dosage. In this case, we use the formula:
Dose = Dosing rate × mass
Substituting the given values into the formula:
Dose = 50 mg/kg × 50 kg, which equals to 2,500 mg.
Therefore, you need to administer 2,500 mg of the drug to the patient.

The part of a flower stalk where the parts of the flower are attached.
Explanation:
Also known as stem
B) Nucleoli are large protein complexes that cross the nuclear envelope in eukaryotic cells.
C) Nucleoli are thin, dense meshworks of fibers lining the inner surfaces of the inner nuclear membranes of most eukaryotic cells.
D) Nucleoli are structures made of DNA, RNA, and protein that are present in the eukaryotic nucleus.
Answer:
Option-D
Explanation:
The nucleolus is a structure present in the nucleus of the cell which is important for the cell.
The nucleolus provides the site of transcription of the rRNA genes and the enzymes required for transcription. The nucleoli appear condensed structure as the rRNA genes, some portion of DNA and the proteins in the form of the enzymes like RNA polymerase I.Therefore, nucleoli are made of the DNA, RNA and the proteins.
Thus, Option-D is correct.
Answer: Option D
Explanation:
The nucleolus is the largest structure which is found in the nucleus of the eukaryotic cells. It is the main site for the ribosome biogenesis.
Nucleoli consists of DNA and RNA, proteins and it forms around the nucleolar organizing regions. it also help in cell signaling.
These are like envelops which bounds the nucleus inside it. In case of the treatment of cancer, the main target is nucleolus.
Depending on the type of cell, there are two ways cells divide—mitosis and meiosis. Each of these methods of cell division has special characteristics. One of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes. This type of cell division is good for basic growth, repair, and maintenance. In meiosis a cell divides into two cells that have half the number of chromosomes. Reducing the number of chromosomes by half is important for sexual reproduction and provides for genetic diversity.
