Answer:
Dependent variable: Plant growth
Independent variable: Water
Explanation:
The <u>Independent variable in an experiment is defined as the variable which can be changed or controlled to measure its effect on the dependent variable</u> and change in dependent variable depends on the independent variable.
In the given example quantity of water is an independent variable and plant growth is a dependent variable because quantity of water can be controlled that influences plant growth.
Hence, the correct answer is:
Dependent variable: Plant growth
Independent variable: Water
The immune system monitor continuously the lymphocyte cell levels in order to ensure the protection of the body. These cells are a type of white blood cells that are important in determining the specificity of the response of the body to foreign substances and infectious microorganisms. This group of cells include the T cells, B cells and the natural killer cells. These are produced in the bone marrow and are transported to the lymphatic systems like the thymus, spleen and the lymph nodes. The NK cells function in cytotoxic innate immunity or the cell-mediated ones. T-cells would function by connecting to virus antigens on the outside of a cell that is infected while B-cells would connect to the virus directly in its surface.
the answer is false, though we adapt in our lives, we simple cannot just add or delete traits the help us survive.
Answer:
mostly likely its that the universe may continue to expand
reason: Its a theory called the Big Bang theory that basically tells us about the existence of the universe and how it has formed things in our universe such as galaxies and is still expanding today also it's a Law called Hubble Law that says the greater the distance of a galaxy from us the faster it recedes which also shows proof of universe expansion
