What do you think is the difference between direct effect and indirect effect?

Biology

Shalnov [3]3 years ago
7 0

Answer: In direct effect, the person is directly affected by the source. For example, if a volcanic eruption occurs and lava flows outward, the area surrounding the volcano - including human establishments and organisms that reside there - would be affected (DIRECTLY); however, we observe that acid rain forms after this. This is because the sulfurous gases from the eruption mix with water vapor in the atmosphere. Another indirect effect of this is actually positive - radiation reflection. When a volcano eruptions, it releases gases like sulfur dioxide. Sulfur dioxide would react with other substances and produce aerosol particles. Aerosols can have huge impacts on our climate as they reflect light. This is evident when Mount Pinatubo erupted in 1991, and as a consequent, the aerosols that were produced from its gases cooled the area for 4 years.

aksik [14]

Answer:

12-14 october

Explanation:

The probable period of exposure is calculated as follows:

  1. Know  the range of the incubation period
  2. Start counting back from the days of the first case by subtracting the first number of incubation period range
  3. Count back the days from the last case by subtracting the last number of incubation period range.
  4. This will give a range which will be the period of exposure.

From the question,

  • Incubation period range 1-15
  • Date of first case = october 15
  • Therefore, first date of exposure = 15 -1 = 14
  • Date of last case = 22
  • Therefore, last date of exposure = 27 - 15 = 12
  • Thus, the range is 12-14 october which is the probable period of exposure.

How can plastics in the ocean impact human health?
Thepotemich [5.8K]
I believe the plastics in the oceans are harmful to ocean organisms and human health when people consume ocean organisms. Each plant and animal play its own role in sustaining the world's largest ecosystem. However, due to the ever-growing waste of humanity, we are gradually upsetting this balance. As a global community, we are unable to effectively implement sustainable habits. We produce a lot garbage, and all that garbage has to end up somewhere.
