Answer:
c. Cold front
Explanation:
Cold fronts are bodies of air with cooler temperatures than the surrounding air. The general effect cold fronts have is that they cause a drastic change in the weather. This is because when they interact with the warmer air, they produce precipitation.
The storm most likely, came with an advancing mass of cold air, which caused the dramatic drop in temperature that was experienced. This is what is known as a cold front.

Answer and Explanation: The figure below shows the doses of BPA administered to the female mice over time.
An experiment is used to determine cause and effect among variables. When the research is for the impact of a treatment, researchers randomly separate individuals in two groups:
- <em><u>Control</u></em> <em><u>Group</u></em> doesn't receive any treament or a placebo or a treatment whose outcome is already known;
- <em><u>Treatment</u></em> <em><u>Group</u></em> receives the treatment;
For the female mice on the image below, in the First Group is not injected any dosage of BPA, so they are the control group, while the <u>others</u> are <u>treatment group</u>.
The variables in a experiment are classified as independents or dependents:
- <em><u>Independent</u></em> <em><u>Variable</u></em> is the cause;
- <em><u>Dependent</u></em> <em><u>Variable</u></em> is the effect;
For the BPA research, since it is the effect of BPA over time on the mice's cells it is being investigated, <u>dosage</u> of BPA is the <u>independent</u> variable and <em>time</em> is the <em>dependent</em> variable.
Answer: False.
Explanation:
Epithelial tissue is found in the linings of many structures throughout the body. There are two kinds of epithelial tissue: simple and stratified. And they perform different functions and are structured differently.
The simple epithelium consists of one single layer of cells. In this way, all cells are in direct contact with the basement membrane and are separated from the connective tissue. The main function of this epithelium is <u>absorption and filtration.</u>
The stratified epithelium is composed of many layers of cells that are stacked together. In this way, this epithelium has the function of <u>protecting against physical and chemical damage.</u>
Primary succession is when, for example, a volcano explodes and there is nothing left and even the soil is ruined. It would take at least a hundred years for the land to be like it was before the volcano erupted. Secondary succession is when, for example, a wild fire happens but the soil is not ruined. It would take at least 25-50 years for the land to be like it was before the fire.
