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?

Answers

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.

List one abiotic and one biotic factor that humans use to limit pest population.

Answers

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.

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.

Answers

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.

What function of the cell does cancer mainly affect?
A. Cell division

B. Photosynthesis

C. Cell transport

D. Cellular respiration

Answers

Answer:

A) Cell Division

Explanation:

When someone has cancer their cells grow abnormally and spread very fast ( which is bad because these cells have cancer in them which spread around your body it’s why most people who are in late stages of cancer usually develop it in other places) . Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.

Cancer cells usually group or clump together to form tumors.

Answer:

A. Cell division

Explanation:

Cancer cells are cells that divide relentlessly, forming solid tumors or flooding the blood with abnormal cells. Cell division is a normal process used by the body for growth and repair.  

In most natural populations rapid exponential growth is unsustainable. As populations
increase, environmental resistance causes the growth rate to slow down, until carrying
capacity is reached. Brainstorm several factors that could be considered as environmental
resistance.

Answers

Answer:
Carrying capacity is defined a the ability of the natural ecosystem to take care of the environment which does not necessarily cause the resistance in population increase.
Explanation:
The earth indeed has a mechanism of delivering changes to the system and keeping it intact but as the case of the rapid growth of population arises the mother nature sees this as an exponent of unsustainable growth as the resource used to sustain large populations is no longer available or are exhausted.
A population increase so does the carrying capacity and workload of the natural environment which at the time gets slow due either due to the man's artificial technology or the natural process like hurricane or earthquake itself.
But seeing the nature as providing possibilities for the existence of the societies throughout ages and hence trying to maintain its originality may break those activities that it considers resistance as several biotic factors like predators, disease, competition, and lack of food.
