Answer:
The correct answer is - Neither ball has a charge
Explanation:
If the two balls are hanged near one another without touch or an external charge to any of the balls there would be no charge present. In the given question is it given that two balls hang down without any contact in them.
So there is no possible way to generate charge and remain uncharge in their position till they get any external charge.
The correct answer is - Neither ball has a charge
Explain why the passenger pigeon,which was once the most abundant bird in north America,disappeared completely.
Answer with Explanation:
The "passenger pigeon" used to be North America's most popular bird. Their population even reached 3 billion (or even more). They always traveled together. Their decline in number was noted in the 19th century. People became interested in hunting them for food because they were relatively cheap and tasty . They were also a great source of protein. It was easy to hunt them down although they could fly very fast because their flocks were huge in number. Some people killed them because they didn't want the birds ruining their crops. Their nesting grounds were also disturbed, which ultimately drove them away from the forests. People were overkilling them, and this sped up with the advancement of technology. The number of pigeons killed outnumbered the newborn pigeons, and after decades of hunting them down, their number dwindled with the last one passing away in 1914.

describe the water cycle process starting from an afternoon thunderstorm.
Answer:
Most thunderstorms form by a cycle that has three stages: the cumulus stage, mature stage, and dissipating stage.
Cumulus Stage
The sun heats the Earth's surface during the day. The heat on the surface and warms the air around it. Since warm air is lighter than cool air, it starts to rise (known as an updraft). If the air is moist, then the warm air condenses into a cumulus cloud. The cloud will continue to grow as long as warm air below it continues to rise.
Mature Stage
When the cumulus cloud becomes very large, the water in it becomes large and heavy. Raindrops start to fall through the cloud when the rising air can no longer hold them up. Meanwhile, cool dry air starts to enter the cloud. Because cool air is heavier than warm air, it starts to descend in the cloud (known as a downdraft). The downdraft pulls the heavy water downward, making rain.
This cloud has become a cumulonimbus cloud because it has an updraft, a downdraft, and rain. Thunder and lightning start to occur, as well as heavy rain. The cumulonimbus is now a thunderstorm cell.
Dissipating Stage
After about 30 minutes, the thunderstorm begins to dissipate. This occurs when the downdrafts in the cloud begins to dominate over the updraft. Since warm moist air can no longer rise, cloud droplets can no longer form. The storm dies out with light rain as the cloud disappears from bottom to top.
The whole process takes about one hour for an ordinary thunderstorm. Supercell thunderstorms are much larger, more powerful, and last for several hours.

this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
Answer:
B. 3.12 x [tex]10^{-3}[/tex] m
Explanation:
From the given picture, it can be deduced that;
the diameter of the image of lumen = 25.0 mm
= 25.0 ÷ 1000
= 0.025 m
And,
magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]
But magnification = 8,and diameter of the image of lumen = 0.025 m.
So that;
8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]
⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]
= 0.003125
Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection
Answer:
Due to muscle contraction and fighting of white blood cells.
Explanation:
Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.
Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere
Answer:
D. The biosphere change the lithosphere
Explanation:
The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.

Explanation:
Aerobic Process: Oxygen, Carbon Dioxide by-product
Anaerobic Process: Carbon Dioxide, Fermentation
Both: Produces ATP, Takes place in cells
What is respiration ?Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic substances.
Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen. Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration. Compared to anaerobic respiration, aerobic respiration produces more energy.
Thus, respiration is a vital process of the body.

How has human land use impacted the environment?
the answer is for anyone who needs it Ways that humans impact the environment is pollution and deforestation which can cause global warming and mass extinction. When humans pollute the earth they slowly start to cause global warming. When we burn fossil fuels to generate electricity, drive our cars, and power our lives we release heat trapping gasses into the atmosphere which slowly makes the world warmer. Deforestation get rid of some of our oxygen supply but it also can lead to mass extinction. When we cut down and burn trees it gets rid of animals homes. If the animals homes get destroyed they are forced to compete with other animals for their survival. Therefor one animal will survive while the other one dies and if this process occurs frequently it leads to many animals going extinct.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
Human activities causes extreme adverse conditions in the environment which resulted eben in the eventual devastation of some species from earth. The selfish actions of humans causes all kinds of pollution in nature.
What are human impacts?The term "human impact on the environment" (or "anthropogenic impact") refers to alterations to biophysical environments as well as to ecosystems, biodiversity, and natural resources.
Environmental changes made to meet societal requirements have negative repercussions. global warming, environmental deterioration (such as ocean acidification), mass extinctions and biodiversity loss, ecological catastrophe, and ecological collapse, to name only a few.
Population expansion, overconsumption, overexploitation, pollution, and deforestation are some human activities that harm the environment on a global scale.
It has been suggested that some of the issues, such as global warming and biodiversity loss, pose grave hazards to the existence of the human species.

what is the function of photosystems
Answer:
Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes.
Explanation:
The main functions of a photosystem are: they are a functional unit of photosynthesis, and they trap or release light.
What is a photosystem?Plants, algae, and cyanobacteria all have thylakoid membranes that contain photosystems. These membranes are found in the cytoplasmic membrane of photosynthetic bacteria as well as the chloroplasts of plants, algae, and other vascular organisms. The PSI and PSII subtypes of photosystems exist.
The functional components of photosynthesis are called photosystem, and they are identified by specific pigment organization and association patterns.
Therefore, the photosystem is responsible for absorbing and transferring light energy, which entails transferring electrons. The thylakoid membranes contain photosystem in terms of physical location.
