Answer:
floor tiles is dependent
wax is the independent
Explanation:
floor tiles needs to depend on the wax to not get scratches
wax does not need to depend on anything
The type of floor wax (Tough Stuff or Steel Seal) is the independent variable, being manipulated for the experiment, while the level of protection against scratches is the dependent variable, being measured and compared.
In this experiment, the independent variable is the type of floor wax being used (either Tough Stuff or Steel Seal), as this is the factor that is being systematically manipulated to determine its effect on the outcome. The dependent variable is the level of protection the floor tiles have against scratches, which is what is being measured and compared between the different wax types.
The independent variable in this experiment is the type of floor wax being tested, with the two options being the more expensive Tough Stuff floor wax and the cheaper Steel Seal floor wax. The dependent variable is the level of protection provided by the floor wax against scratches on the floor tiles.

B. Knowledge and valuable resources are shared among scientists.
C. An experiment is repeated several times to verify the results.
D. Multiple forms of evidence are used to support a conclusion.
the right answer is b
If we put a Rhoeo leaf in plain water, the water concentration of the leaf cells will be higher than that of the plain water. The aim is to balance water concentration on the inside and outside of the organism. So, the water will exit the leaf cells, which will consequently shrink in size. The most of the cells will shrink in size, causing the leaf to shrink, too.
The ovary is the part of the female reproductive system that produces ova.
The ovary is an organ located in the female reproductive system that produces female reproductive cells or ova. The ovary is often paired and are firm, smooth and about the size of an almond. The ovaries are held by a membrane next to the uterus on both side of the lower abdomen. When an ovum is produced, it moves into the uterus through the fallopian tube, where it may be fertilized by a sperm. The ovary also secretes various hormones such as estrogen and progesterone that perform major roles in the menstrual cycle and fertility.
