Warm air moves upward, while cold air moves downward. Which of the following best explains this pattern of heat transfer?
A
Differences in density caused by temperature differences create buoyant forces.
B
Gravity pulls cold air downward more strongly than warm air.
C
High-energy particles bounce upward off the ground in large numbers, causing convection.
D
Gravity acts on particles but not on energy, so thermal radiation rises.
Answer:
A) Density
Explanation:
cold air is more compact than warm air since particles aren't as active, therefore it is more dense and heavier than warm air.

resistance.

List one abiotic and one biotic factor that humans use to limit pest population.
Answer: temperature, animal
Explanation:
Abiotic factor is a non-living environmental factor like soil, water, temperature, humidity, sunlight, and others. Biotic factor is a living factor including living beings like microbes, humans, insects, and others. A limiting factor is the one which can reduce the abundance and growth of living organisms. A limiting factor can be abiotic or biotic.
Temperature is one of the abiotic factors which can reduce the abundance of pests. Increase in temperature can kill pests, which cannot tolerate the rise in temperature. Animal that feed on pests can also reduce the abundance or population of the pests. Like lizards, frogs, and others.

when were biofules invented?????????????
Answer:
1930s
Modern biodiesel fuel, which is made by converting vegetable oils into compounds called fatty acid methyl esters, has its roots in research conducted in the 1930s in Belgium, but today's biodiesel industry was not established in Europe until the late 1980s.
Explanation:
I searched it up it.
1853 or 1893
Even though scientists E. Duffy and J. Patrick experimented with biofuels as early as 1853, the first engine created to use biofuel was by Rudolph Diesel. In fact, Rudolph Diesel showed the first biofuel car engine in Augsburg, Germany on August 10, 1893. Since then, August 10 has been known as International Biodiesel Day.

How have the factors that trigger an asthma attack changed since the 1900s? As a researcher, how would you put together the clues given here to explain the emerging epidemic?
so if you look up things that can cause an asthma attack it will also show that viruses and bacteria are a cause. with asthma you lungs could already be inflamed as well as your air way wich makes it harder to breath. when you have c-19 it will inflame your lungs even more so it makes it even harder to breath given an asthma attack. more asthma attack now are probably caused by c-19 because it is all over the place and the percent of asthma attack by virus has dramatically increased.
