Answer:
independent, dependent, control
Explanation:
The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.
The dependent variable is what you measure. This <em>depends</em> on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.
Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.
Answer:
O blood is a recessive trait, so none of the children will have O blood. The genes for either type A or Type B will be determined by the egg/sperm being fertilized with the reproductive cell of the other parent. the probability of receiving either of the gene versions is 1/2, so half of the children will have A blood and the other half will have B blood
B is correct, Organisms in the same group have similar characteristics
Radioactive materials that are high energy and will cause cellular and tissue damage are usually known as ; Alpha radiation.
<h3>
What is Radioactive material and Alpha Radiation ?</h3>
- Chemicals in the class of radionuclides (also known as radioactive materials) have unstable atomic nuclei. They stabilize themselves by altering the nucleus (spontaneous fission, emission of alpha particles, or conversion of neutrons to protons or the reverse).
- For example, the Earth's crust naturally contains the radioactive elements uranium and thorium. These two elements slowly alter their forms over billions of years, leading to the production of decay byproducts like radon and radium. Energy is released during this process. Alpha radiation is one type of this energy.
- Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.
