In 1976, an outbreak of pulmonary infections among participants at an American Legion convention in Philadelphia led to the identification of a new disease, Legionnaire's disease. The bacterium responsible for the disease had never before been known to be pathogenic. From your knowledge of bacterial genetics, can you postulate how it might have acquired the ability to cause disease
Answer:
Evolution.
Explanation:
It might have acquired the ability to cause disease due to evolution. Due to evolution, the harmless bacteria can turn into infectious pathogens that cause diseases. Evolution is the change in the characteristics of a species over several generations due to the process of natural selection. This evolution in the bacteria occurs due to changing of environmental conditions which changes the genetic makeup of that harmless bacteria and turn into infectious pathogen.
Which would indicate the water in a lake is not safe for drinking? A. many varieties of fish in the lake B.high dissolved oxygen levels in the lake C. cold water temperature of the lake D. high turbidity levels in the lake
The water in a lake is not safe for drinking, high turbidity levels in the lake Coliform bacteria occur innately in soil and in the intestines of humans and other organism.
What is dissolved oxygen in water?Dissolved oxygen (DO) is the quantity of oxygen that is current in water.
Water bodies obtain oxygen from the atmosphere and from aquatic plants.
Rushing water, such as that of a fast moving stream, dissolves more oxygen than the still water of a pond or lake

Which of the following describes a portion of the water cycle that is not driven by
gravity? O
(1 Point)
B) Precipitation of water that has condensed from clouds
D)Water seeping into the ground to enter an aquifer
C)Water flowing in a river toward the ocean
A) Evaporation of water from the ocean to form clouds
The correct answer is A. Evaporation of ocean water to form clouds.
Explanation
The water cycle is a series of physical-chemical phenomena in which water goes through three states (liquid, solid and gaseous). In this process, the water in a liquid state is evaporated becoming in a gaseous state, and rising towards the sky (against the force of gravity) forming clouds. Once in the clouds, the water condenses, going from a gaseous to a liquid state. After this process, the water precipitates by the action of gravity towards the earth where a process such as the filtration of water in the soil occurs, forming aquifers, the accumulation of water in the rivers that flow into the sea, the freezing of water on the snowy peaks of the mountains, among others. According to the previous explanation, the correct answer is A. Evaporation of ocean water to form clouds.
In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar.

Large and small particles are found mixed in a fast-moving stream. What type of erosion is this?
A. Suspended load
B. Traction load
C. Dissolved load
D. Bed load
I think the answer is bed load
Explanation:
bed load describes particles in a flowing liquid that is transported along the stream bed
A bed load includes large and small particles are found mixed in a fast-moving stream. The correct option is D.
What is a bed load?The descriptor bed load or bedload refers to particulate in a flowing fluid basically water that are carried anywhere along stream bed. Bed load works in tandem with suspended load and wash load.
Conventionally, parameters of bedload have been taken by placing samplers in contact with the bed and permitting the sediment transferred as bedload to accrue (or be trapped) inside the sampler for a certain amount of time before raising the sampler to the surface and emptying the material.
Once the critical boundary shear stress is exceeded, coarser grained material tends to move in intermittent contact with the bed.
This movement, known colloquially as "bedload transport,"
Thus, the correct option is D.

How does deforestation impact greenhouse gases in the atmosphere the most?
A.
Deforestation increases the build-up of greenhouse gases because the removed trees would have consumed carbon dioxide.
B.
Deforestation removes trees, which shelter organisms that release gases that purify the air.
C.
Deforestation decreases the amount of greenhouse gases because trees produce many of them.
Answer:
Deforestation increases the build-up of greenhouse gases because the removed trees would have consumed carbon dioxide.
Explanation:
Answer:
A. Deforestation increases the build-up of greenhouse gases because the removed trees would have consumed carbon dioxide.
Explanation:
Burning fossil fuels, in combination with the destruction of carbon sinks due to deforestation and other activities, has contributed to more and more carbon dioxide building up in the atmosphere – more than can be absorbed from existing carbon sinks such as forests.

Because of global climate change, arctic landscapes and ecosystems are changing rapidly and perceptibly, as the residents of Newtok, Alaska, can attest. With the land upon which they have built their homes slowly melting and sinking, they have appealed to the state and federal governments for assistance in helping them cover the costs of moving their town to a different location. Ironically,
A) the land upon which the Alaskan state government buildings are located is also melting.
B) the residents of Newtok have discovered oil on their land, making their appeal for funds less convincing.
C) a senator from Alaska has a vacation home in Newtok, Alaska, and so is personally committed to the predicament of the town.
D) decades ago, the U.S. government mandated that they and other Alaskan natives abandon a nomadic life based on hunting and fishing for sedentism.
E) the economic activity of the town of Newtok is extremely polluting and thus a big contributor to the environmental changes that have turned its residents into the first climate change refugees in the United States.
Answer:
The correct answer is D)
Decades ago, the U.S. government mandated that they and other Alaskan natives abandon a nomadic life based on hunting and fishing for sedentism.
Explanation:
Sedentism is simply the practice of settling in one geographical location for a long time.
Many governments encourage this to ensure that agricultural systems become developed and more sustainable as was the case in Alaska.
Other governments in some part of the world are also in support albeit for a different reason such as security of lives and property.

The graphs here show the distribution of beak depths for the ground
finches on Daphne Major, an island in the Galapagos. The bird beaks were
measured over a multi-year study, including a time period before and after
a drought. The drought reduced the supply of seeds and left most of the
seeds as thick-walled nuts that survived the drought. Analyze the data and
select the claim about natural selection and genetic diversity that is
supported by the data.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select for the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as there were more ground
finches after the drought, and it tends to select for the most fit phenotypes, as there
was an increase in average beak depth after the drought.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select against the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as the average beak size
increased after the drought, but it tends to select against the most fit phenotypes, as
there was a decrease in population size for the finches after the drought
Answer: (A) Natural selection tend to reduce genetic variation as there was a smaller distribution of beak depths, but it tends to select for the most fit phenotypes, as there was an increase in average beak depth after the drought.
Explanation: The picture below shows proof if needed. On USATP
Natural selection tend to reduce genetic variation as a smaller allocation of beak depths, but it tends to select for the most fit phenotypes, as an increase in average beak depth after the drought.
How does natural selection affect genetic variation?Genetic variations that vary gene and protein role.
If a trait is favourable and helps the someone survive and breed, the genetic variation is more likely to be passed to the next generation.

Move the bonfire to the left side of the sand. Observe how the smoke from the bonfire moves"" Dose anyone know how to get past this?
Fire requires three things heat, fuel, and oxygen. The heat source is a match. The firewood burns and provides its own heat to keep it burning. Fire needs oxygen, which can be obtained from fresh air. Air gets hot and denser.
When fire burns, heat transfers kinetic energy to the molecules. As the kinetic energy increases, there are more collisions between molecules. The hot air becomes less dense. As less dense than the cold air around it, the hot air rises and carries the smoke with it. Therefore, the smoke moves away with the wind.
