Magnification power is 600X
Explanation:
15X and 40X indicating that the object is enlarged 15 times and 40 times. Formula is X = lens power X objective lens power.

Answer:
Dependent Variable
Explanation:
An experiment has dependent and independent variables. The dependent variable is the one that is being studied and responds to the independent variable.
In the given experiment, the effect of a new drug is being studied on blood pressure. Here, the blood pressure (systolic and diastolic blood pressure) is supposed to change in response to drug treatment.
So, blood pressure is a "dependent variable" while the drug treatment is "independent variable".
The answer is; C
Meisos involve halving the genetic material of a cell to form garments. The gametes of two parents fuse to form a zygote that6 returns the genetic material to normal ploidy so it can develop into offspring. The fusion of two gametes is called fertilization.
Answer:
Flatworms are beings that do not have a heart, veins, arteries, capillaries, hemolymph, or some type of circulatory fluid. Their circulation occurs between cells or intercellularly and they are responsible for transporting substances by diffusion from cell to cell.
Explanation:
Flatworms are considered multicellular eukaryotic organisms. This implies that in their cells they have a cellular nucleus, in which the DNA is contained, structuring the chromosomes. Likewise, they are made up of several types of cells, each one specialized in a specific function. They lack a structured circulatory system as such. Because of this they do not have specialized structures such as a heart or blood vessels, however, the circulation of certain substances is established between their cells. This is done thanks to the diffusion process. Substances pass from one cell to another through this process.This does not apply to all flatworms, since in some species of bog and digenae there is a certain organization and some very small conducting vessels known as the endolymphatic system, the which forms a kind of plexus in the parenchyma.It should also be noted that some species do not even have a digestive system, being the digestive tract the one in charge of digestive functions and the distribution of the nutrients they receive.
