Answer:a
Explanation:
Answer:
The correct answer is "False".
Explanation:
There is no data to support the statement that unintended pregnancy is more likely than intended pregnancy to result in early prenatal care. There are other factors that affect early prenatal care, such as age, culture, economics, marital status or mental health conditions of the parents. Unintended or intended pregnancy is not related with the propensity of giving early prenatal care.
Greenhousegases are added to the atmosphere through forestfires. The correct option is A.
Greenhousegases are gases the gases which basically trap heat in the earth's atmosphere. The sun shines through the atmosphere during the day, warming the earth's surface.
The earth's surface cools at night, releasing heat back into the atmosphere. However, some of the heat is trapped in the atmosphere by greenhouse gases.
Greenhousegas emissions have far-reaching environmental and health consequences. They contribute to respiratorydisease due to smog and air pollution, and they cause climate change by trappingheat.
Other effects of climate change caused by greenhousegases include extreme weather, food supply disruptions, and increased wildfires.
Carbon dioxide, methane, nitrousoxide, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and ozone are the main greenhouse gases whose concentrations are increasing in the loweratmosphere.
Thus, the correct option is A.

tools to avoid rusting?
To prevent kitchen tools made from iron from rusting, one can paint them, use stainless steel alloys, or store them in a way that prevents contact with air and water.
To help preserve kitchen tools from rusting, there are few precautions that you can take. The first method is painting iron tools. Water and oxygen come into touch with iron and cause rust, but a coat of paint can stop this from happening. The iron is immune to rust as long as the paint is still on it.
Another strategy is alloying the iron with other metals to form, for example, stainless steel, an iron alloy containing a small amount of chromium. Chromium tends to collect near the surface, where it erodes and forms a passivating oxide layer that protects the iron from rusting.
Lastly, storing your iron kitchen tools under kerosene or mineral oil or in sealed containers could prevent rust by limiting their contact with air and water.
