Answer:
a combination of large groups of people, and they are all travelling- which increases the spread.
Answer:
The reason airports, trains, cruises, and bus stations are considered high risk areas for biological warfare is because they all have a high number of people in them which means that there will be more fatalities.

advantage and disadvantage of minilap
Answer:
Advantages
• After the procedure, the female will no longer have to worry about becoming pregnant again.
• It causes no hormonal changes to the body.
Disadvantages
• The procedure is difficult to reverse. So even if there is a slight chance that you might consider having children in the future, this procedure is not meant for you.
• Tubal ligation does not offer any protection against sexually transmitted diseases.
• If in case the procedure fails and you become pregnant, you have an increased risk of ectopic pregnancy. Ectopic pregnancy is the one where the foetus develops outside the uterus.
• Any kind of surgery is prone to complications and the same applies to mini-laparotomy as well. The surgery might result in some or any kind of infection, bleeding, injury to the bowels, bladder, or uterus. It may also result in permanent scarring.
In May 2018, the Kilauea volcano on Hawaii's Big Island began to erupt, spewing lava over part of the island.
Which event are Hawaiians most likely to observe first in the areas covered by lava?
A. Mosses will grow in thin, rocky soil.
B. Lichens will grow on the cooled lava.
C. Trees will grow in thick, rich soil.
D. Grasses will grow in soil with organic matter.
Primary succession occurs after the occurrence of a severe event that leaves nothing but rocky surfaces. Option B. Lichens will grow on the cooled lava.
What is succession?
The succession term refers to colonization and subsequent changes.
Colonization has been defined as the sequence of events that conduce to the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.
Succession refers to changes produced in the composition and structure of communities after a perturbation. There are different grades of succession according to the perturbation intensity.
What is Primary succession?In primary succession, the perturbation is so intense that it eliminates all the life forms in the area.
It is the sequence of species appearance in an exposed area that has not been influenced by any other species or community before.
In these cases, the rock gets exposed but it can not be colonized directly. The new area needs to suffer erosion and different chemical and physical processes that fragment, degrade and dissolve the rock to make colonization possible.
Primary succession occurs after severe events affecting a region, such as a retreating glacier, a volcanic activity, or an intense fire that leave nothing but the exposed rock.
After the disturbance, the order of the living beings establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space.
Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses.
Grasses and pioneers keep modifying the ground and making it better with time.
Habitat modification keeps on going while new species establish. They produce shadows and alter the temperature, and humidity, fertilizing the soil.
Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources.
This sequence continues until there is no more facilitation, and the communities reache a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
In the exposed example, the severe event affecting the Hawaii's Big Island was a volcanoe eruption.
The most likely event observed first in the areas covered by lava would be Lichens will grow on the cooled lava. Option B

Rain washing oily runoff from a road into a river that runs alongside the road is an example of point source pollution or nonpoint source pollution?
Help pls.
Answer:
This would be an example of nonpoint source pollution.
Explanation:
The source of point source pollution is typically factories and powerplants, leading to more air and water transferred pollutants and becoming easier to track. Nonpoint source pollution is the opposite of point-source pollution, with pollutants being released in a wide area. Since the rainwater would be washing the oils and particles into the water, it would be considered runoff. Runoff is one of the leading causes of point source pollution. I hope this helps. ^_^
What effect do the sulfate aerosols formed by volcanoes have on global temperatures?
Answer:
There is overall agreement that volcanic sulphate aerosols in the stratosphere can reduce solar radiation reaching the earth's surface for years, thereby reducing surface temperatures, affecting global circulation patterns and generally the global climate system.

Imagine you are a population ecologist who is starting a campaign to control invasive species in your community. Write 3-5 sentences about what you would tell members of your community who come to a meeting to learn about invasive species.
Answer:
This is what I would say:
Hello, today I will talk to you about invasive species and why they should be stopped, invasive species are bad for the environment because they destroy other creatures, like if the native species think that it's prey and decide to eat it; it might harm them. For example, if there were trees in a certain environment and an invasive species came along every creature would get hurt because those trees are very tall and they stop sunlight from reaching the ground so that would help to stop invasive plants from growing but if an invasive species of beetles came along they would eat the trees and kill them making sunlight reach the ground. Then it would help the invasive plants to grow, and what would the invasive species of plants do you ask? They would harm the creatures because there are herbivores and they eat plants and since they might think that the plant is toxic because they look like a toxic plant in that environment they will starve and die. Little by little the animals would get harmed because predators eat the herbivores and if there's no food for them they will die, so you see a lot of creatures would get harmed if we don't stop invasive species.

What types of health related issues might be associated with climate related factors?
A) malaria
B)
skin cancer
C) hypothermia
D) elevation sickness
E) all of the above
Answer:
E) All of the above
Explanation:
Malaria, is caused by mosquito bites, and mosquito's follow warmth, so if climate changes to warm really quickly more people are likely to get malaria. Skin cancer can be caused by sun radiation, or staying in the sun for to long, so if climate changes again to really warm, you can get skin cancer if not careful. If your to hot you can go in hypothermia shock. And if the elevation increases or decreases to quick you can get elevation sickness. All of these options change, because of the climate around them, therefore the answer is E. I hope this helps :)
Why would your heart rate increase or decrease to help maintain homeostasis when you exercise?
Answer:
The cardiovascular system helps to maintain homeostasis with respect to body temperature. An increased heart rate increases the delivery of blood to your skin. Increased blood flow to your skin and sweating causes dissipation of heat, and body temperature remains within normal limits.
Explanation:
Answer:
well here mate.
Explanation:
the reason i9s while exercising different exercises require different levels of energy therefor why you do push ups your heart rate will beat very fast depending on how long you have been doing them, and when you jog you are at a comfy speed there fore your heart rate stays low and calm.
