3. What is the scientific term for a group of interacting individuals of the same type, living in the same area at the same time?
Answer: The scientific name is called POPULATION.
Explanation:
In basic ecological studies, POPULATION is defined as a group of interacting individual of the same type or species, living in the same area or habitat and at the same time.
Furthermore, to study a population of organisms, the different characteristics seen include:
--> Population size: This is important as it affects the survival of a given species in a habitat. A small population may be easily wiped out by events such a fire but a large population stands a better chance of survival.
--> Population frequency: This is simply how often the species occurs at different sites in a habitat.
--> Population density: this is the average number of individuals of a species per unit area of the habitat.
--> Percentage cover: This is the area of ground occupied by a given species in its habitat.
--> Distribution: This is the way in which individuals of a particular population are arranged in a habitat. They may be clumped, evenly spaced or randomly spaced.
Match the vocabulary words below with the correct unit of measure:
Acceleration --> meters/second/second (m/s^2)
Acceleration measures how fast something is speeding up. Speed measures how far something goes in a certain amount of time; acceleration measure how fast that speed is increasing (does that make sense? ask question if you need more clarification).
Velocity --> meters/second (m/s) south
Velocity is speed with a direction. Above I explained what speed is.
Force --> Newtons (N)
That's just what force is measured in.
Distance --> meters (m)
Meters is a unit of distance, or how far it is. It's not moving so there is no time component.
Mass --> kilograms (kg)
Kilograms is a unit of mass. Generally anything with grams is going to be a unit of mass.

Infer how jupiter could have become another sun if it had been larger
Answer:
Jupiter is bigger than most stars so it would make sense that it become another sun but...
Explanation:
Jupiter needs more mass to meld hydrogen into helium. EBLM J0555-57Ab is around multiple times the mass of Jupiter, probably really light - on the off chance that it were any lower, it would not have the option to combine hydrogen all things considered.

A virus has wiped out the grasshopper population in the area. What effects to the ecosystem will most likely occur?
Answer:
Those who prey on grasshoppers will have their population decline while the grass population will rise.
Explanation:
Organisms need food to survive. If their food is gone, they won’t thrive as well. This isn’t saying they’ll go extinct, as they may have other food sources, but life will be harder with one food source gone. Since grasshoppers eat grass, the grass population will rise some due to a lack of predation. Hope it helps :)

2. What are some ways water moves in Earth's atmosphere?
3. Describe the role of oceans in the water cycle?
4. Describe the role of gravity in the water cycle?
5. How does the sun's energy contribute to the movement of water in the water cycle?
Answer all 6 questions plzzz
Answer:
1.2The main processes involved in the movement of water between the different reservoirs are evaporation, condensation, transport, precipitation, runoff (water runoff from the ground surface), infiltration and transpiration
3.The large surface of the oceans (about 70 percent of the earth's surface is covered by oceans) favors the occurrence of large-scale evaporation. On a global scale, the same amount of water that is evaporated returns to Earth as precipitation. This however varies geographically
4.Earth from Space Although the engine of the cycle is the solar energy that originates the evaporation of liquid water, and therefore its passage into the atmosphere, the role of gravity is also fundamental, thanks to which precipitation falls and continental waters return to the oceans
5.The water cycle is powered by solar energy. The sun heats the surface of the ocean and other surface waters, which evaporates liquid water and sublimates ice, converting it directly from a solid to a gas. These sun-driven processes move water into the atmosphere in the form of water vapor
Explanation:

Water is the most important abiotic factor. The process of evaporation, condensation and precipitation causes the movement of the water in the atmosphere.
What is the movement of the water and water cycle?Evaporation is the process by which the sun's heat causes the water to evaporate, cooling by the condensation, transportation in the cloud particles, precipitate from the clouds to ground through precipitation, infiltration and transpiration are the process by which the water moves on an in the atmosphere.
Oceans are part of the water cycle as they account for 70% of the earth's surface and major of the water gets evaporated from these surfaces. The precipitate however comes back and hence the cycle continues.
Gravity is the force experienced by the planet and aids the precipitation of the water in the form of rain, hails, snow and sleet from the atmosphere towards the earth's surface.
Sun or solar energy plays an important role in the water cycle as the heat from the sun evaporates the water from different sources by the process of evaporation. It converts the liquid water vapour into gaseous forms.
Therefore, the sun and oceans are part of the water cycle and evaporation is the major part of the water cycle.

BRAINLYMENTALMENTEYeast is added to bread dough before baking. After several minutes, the bread dough rises. Use your experiment to explain how respiration of yeast is important for the baking process.
Answer:
The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.
While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.
Make a yeast-air balloon to get a better idea of what yeast can do
Yeast is a unicellular fungus which undergoes anaerobic respiration to produce ethanol and carbon dioxide gas.
How does yeast fermentation work in bread-making?In a process known as fermentation, yeast consumes the sugar present in the dough to produce carbon dioxide and alcohol.The dough is kept in a warm area throughout the baking process.Fermentation occurs as a result of heat.However, if the temperature is too high, the yeast is killed during the cooking process.As the dough ferments, carbon dioxide is created and trapped as microscopic air bubbles. The expansion of carbon dioxide during baking allows the bread to rise higher. During the bread-baking process, the alcohol created during fermentation evaporates.This is how yeast fermentation plays a vital role in the baking process.

2. Decreases
3. Increases
4. Decreases
5. Increases
6. Increases
Explanation:
Raising air temperature increases temperature of our body while on the other hand, if the air temperature decreases the temperature of our body also decreases because high air temperature heats up our skin surface and low air temperature cools down our skin surface which ultimately increases or decreases the internal body temperature. Adding clothing increases body temperature due to capturing of heat produced by our body. Sweating cools down our body temperature because the water takes the internal heat with itself to the outside. In shivering, the body produced heat so the body temperature increases. Exercising also produces heat inside our body which increases the body temperature.

why is there minimal seismic and volcanic activity in New York
NY1 does state that New York is not close to a tectonic plate, and it is uncertain which one of these faults—if any—would be the source of a strong earthquake.
Answer:
Explanation:
lthough the eastern United States is not as seismically active as regions near plate boundaries, large and damaging earthquakes do occur there. Furthermore, when these rare eastern U.S. earthquakes occur, the areas affected by them are much larger than for western U.S. earthquakes of the same magnitude.[1] Thus, earthquakes represent at least a moderate hazard to East Coast cities, including New York City and adjacent areas of very high population density.
Seismicity is scattered throughout most of the New York metropolitan area, with some hint of a concentration of earthquakes in the area surrounding Manhattan Island. The largest known earthquake in this region occurred in 1884 and had a magnitude of approximately 5. For this earthquake, observations of fallen bricks and cracked plaster were reported from eastern Pennsylvania to central Connecticut, and the maximum intensity reported was at two sites in western Long Island (Jamaica, New York and Amityville, New York). Two other earthquakes of approximately magnitude 5 occurred in this region in 1737 and 1783.[2][3][4]
The map shows earthquakes of magnitude 3 and greater that occurred in this region from 1924 to 2010, along with locations of the larger earthquakes that occurred in 1737, 1783 and 1884. More recently, the 2011 Virginia earthquake, a 5.8 magnitude quake centered in northern Virginia that occurred on August 23, 2011, was felt by the occupants of some buildings in Manhattan, more than 200 miles north of the quake's epicenter and caused minor physical building damage in Brooklyn.[5] There were some disruptions, including building evacuations and delays at airports, while Amtrak train service at Penn Station was also delayed.[6]
