NEED HELP ASAP: List two ways in which the atmosphere would be impacted in the absence of the biosphere. Use complete sentences.
Answer:
If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.
There would be no negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.
Hope it help!
There would be more carbon dioxide, which would eventually burn away the ozone layer, as well as no oxygen, and all animal and plant life would perish.
What is biosphere?The biosphere is basically comprised up of the areas of the Earth where life can be found.
The biosphere encompasses all the things from the deepest tree root systems to the dark environment of ocean trenches, including lush rainforests, and high mountaintops. Earth is described by scientists in terms of spheres.
Because it is all of life, the biosphere is as important as life itself. Earth would be a lifeless planet like Mars or Venus without the biosphere. Human insecurity grows as natural resources are depleted.
The biosphere is the zone that contains all living things. The biosphere requires the lithosphere, hydrosphere, and atmosphere to exist. There would be no life on Earth if these three spheres did not exist.
Thus, this way, the atmosphere would be impacted in the absence of the biosphere.

What would be a probable explanation for why there are many endemic plants and birds in New Zealand, but no native mammals?
Answer:
Due to isolated before mammals evolve.
Explanation:
There are many endemic plants and birds in New Zealand, but no native mammals because New Zealand is an island which isolated from Gondwana which is a supercontinent about 85 million years ago. Before mammals evolved, the New Zealand splits and go away from the Gondwana. So due to water only those mammals that can swim or fly colonized in New Zealand but not the land living mammals.

name the device that helps you to maintain potential difference across a conductor
Answer:
battery
Explanation:
Any source of electricity, the battery, or the power supply is there to maintain the potential difference across a conductor.
To measure this difference we use VOLTMETER - Instrument for measuring potential differences, voltage differences. It is called a voltmeter as it allows the measurement of the potential difference or voltage that exists between two points belonging to an electrical circuit. The voltmeter, therefore, detects the voltage.

O A. (b cosc, b sinC)
O B. (b cos C, c sinc)
O C. (a cosB, a sinB)
O D. (a cosc, b sinC)
Answer:c
Explanation:because cosin of b is c
(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.
What is Vertex ?In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.
The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.
In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.
Hence option D is correct.

Three that live in the savanna are lions, giraffes, and elephants. Choose two of these animals. For each one, describe an adaptation that has enabled it to survive in the savanna. Then tell which which animals in the population would be more likely to survive if a dry season was unusually long.
Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.

Explanation:
Bacteriophage is nothing but a virus that harms and kills the bacteria.
The Hershey-Chase Experiments is a well known experiment done by scientist, Alfred Hershey and Martha Chase. They conducted the experiment in the year 1952.
It was an extra ordinary experiment which made the world believe that the DNA is the genetic material and not a protein. In their experiment, they tried to find out if the protein coat or the core of the DNA of the virus which enters into the infected cells would help them to understand whether the genes were made of DNA or of protein.
They used sulfur-35 and phosphorus-32 radioactive isotopes to trace the DNA and the proteins.

They work independently as closed systems to cycle matter through ecosystems.
They work together as open systems to move matter to living and nonliving parts of Earth.
They work independently as closed systems to move nutrients to living and nonliving parts of Earth.
Answer:
and they work together to drive the processes of the planet.
Explanation:
Earth has four 'spheres,' called the geosphere, hydrosphere, biosphere and atmosphere. These spheres each have unique properties and features, but they are not isolated on Earth, and they work together to drive the processes of the planet.
They work together as open systems to cycle matter through ecosystems. This statement best describes the purpose of Earth's spheres.
What are earths spheres?Lithosphere encompasses the entire solid land of the planet's crust, as well as the semi-solid land beneath it and even the molten core.Hydrosphere is made up of all of the planet's water, which comes in solid, liquid, and gaseous forms. Water comes down to the Earth's surface as precipitation from the atmosphere, rivers and streams along the surface, and groundwater beneath the surface. The majority of the world's freshwater, on the other hand, is frozen.Biosphere is made up of all the living things on the earth. This sphere contains all of the Earth's bacteria, plants, and animals. Living beings establish ecological communities in the biosphere based on their physical surroundings. Biomes are the names given to these types of communities.Deserts, grasslands, and tropical rainforests are just a few of the biomes found inside the biosphere.Atmosphere is made up of all of the air in the Earth's system.The biosphere's organisms are shielded from the sun's UV radiation by the upper atmosphere. It absorbs and emits heat as well. Weather occurs in this sphere as well.
These spheres interact via affecting one another, as well as through biogeochemical cycles and other natural phenomena that each of these spheres influences and causes.

a. A mountain range in Africa lines up with a mountain range in South Africa
b. All of the continents have mountain ranges along the ocean shoreline
c. Each continent shows evidence that glaciers once covered the land
d. Major rivers in all continents flow to the oceans
The evidence from landforms that supports the theory of continental drift and the theory of plate tectonics is that all of the continents have mountain ranges along the ocean shoreline. Thus, the correct option for this question is B.
What is the theory of continental drift?The theory of continental drift may be characterized as the movement of the Earth's continents relative to each other, thereby appearing to drift together across the oceanic bed. It is the hypothesis that the Earth's continents have moved over geologic time relative to each other.
The processes of seafloor spreading, rift valley formation, and subduction are some of the major causes of this continental drift. These processes were the main geologic forces behind what Wegener recognized as continental drift.
The movements of the earth's plate form the landforms that are responsible for creating boundaries of the continents that range along the ocean shoreline.
Therefore, the correct option for this question is B.
