Answers
Answer:
North and South pole are cold as they do not receive direct sunlight. South pole is much colder than North pole. The Sun is always low on the horizon, even during summer and winters.
The Sun only comes up for a few months, that is why both nights and days are dark and cold.
The average mean temperature in summers at North pole is 32 degrees Fahrenheit and in winters its minus 40 degrees. While at south pole it is minus 18 degrees Fahrenheit and in winters it is minus 76 degrees Fahrenheit.

Based on this information, which of the following processes formed the Hawaiian Islands? (2 points) Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled. Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks. One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface. Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.
Answers
Answer:
The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
Explanation:
The Hawaiian Islands are the chain of eight major islands situated in U.S. of Hawaii. These are formed over a hot spot. About 75 million years ago such hotspot took place in the center of the Pacific Plate.
There are hot spot due to the volconic activity and in the moving over the tectonic plate of a subduction zone. Volcanic activity and overriding of plates that cause rising magma by melting the moving down plates whice leads to volcanic arcs formation. The magma that rose gradually cooled down and become solid over the time. It is an example of a large seamount and island chain created by hot-spot volcanism.
Thus, The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.

#1 goes to methane, #2 goes to oxygen,#3 goes to carbon dioxide,#4 goes to carbon dioxide. make sure you double check.
Explanation:
A plant can produce oxygen sufficient for the consumption of four people whereas carbon dioxide absorbed by the plant is more than forty-eight pounds. The total release of carbon dioxide by livestock is 15 % of the greenhouse gas production whereas methane production is 155-264 pounds. When a forest fire happens it releases a massive amount of carbon dioxide which is around 1.8 million tons.
What are greenhouse gases?Greenhouse gases are gases such as methane, carbon dioxide, CFCs, and HFCs. They have impacted the atmosphere negatively. The concentration of these gases is highly rising in the atmosphere at an alarming rate. These gases trap the heat of the sun and do not leak out.
Therefore, the emission of greenhouse gases should be monitored.

Experience with dog breeding has taught geneticists ________. A) that, given enough time, any desired trait can be bred into dogs B) that purebred dogs have offspring with qualities identical to the parents, because all purebred dogs are alike genetically C) that, while physical traits can be molded through artificial selection, behavioral traits cannot D) that geographically isolated groups of dogs may be selected for quite different traits, resulting in a different dog breed
Answers
Answer:
D) that geographically isolated groups of dogs may be selected for quite different traits, resulting in a different dog breed
Explanation:
Artificial selection is a type of selective breeding made by humans in which offspring with desired traits are selected. Modern dogs evolved by artificial selection. Dog breeding began around 30,000 years ago from selective breeding of wolves that were separated from their original population and bred to produce dogs with desired traits (especially, loss of aggressive behavior). Purebred are reproductively isolated groups of dogs originated from the same lineage (i.e., the same common ancestor for each group), that never mated with another dog breed.

Significant amounts of phosphorus are found in all locations on Earth except the..
Answers
Answer:
Atmosphere
Explanation:
Phosphorus cycle in nature is a unique cycle compared to the other natural biological and chemical cycles such as the carbon, nitrogen, sulfur and water cycles, as there is no gaseous phase in the phosphorous cycle. Due to the prevailing atmospheric temperature and pressure which are not appropriate for the formation of gases associated with phosphorus, the compounds in nature where phosphorus can be found are not gases. Phosphorus can therefore be found majorly in sedimentary rocks.
The atmospheric temperature and pressure are incapable of forming phosphorus compounds, Phosphorus has not been found in the atmosphere.
Phosphorus has been the recycled in the atmosphere within the biosphere, lithosphere, and hydrosphere. In the nature, the phosphorus has been present in the sedimentary rocks, with the absorption by plants and animals.
The phosphorus cycle has been consisted of the weathering, absorption by plants and animals and return to the lithosphere with the decomposition. Since the atmospheric temperature and pressure are incapable of forming phosphorus compounds, Phosphorus has not been found in the atmosphere.

An organism that reproduces asexually will have
Answers
Answer:
An offspring identical to itself.
Explanation:
The difference between asexually reproduction and sexually reproduction is that when you asexually reproduce, you are simply duplicating yourself. There are many ways you can asexually reproduce, like after a certian growth time, you would just simply split yourself. A part of you can just come off too. The last one is franmentation. It is when you take a big part of you off, and then if it was big enough, it would grow. (Occurs in Starfish). But when you sexually reproduce, two haploids would come together, creating a diploid which would duplicate. And asexually reproduction, you would already start with a full set of genes. (Which is identical to your mother's)

Answers
Answer:
To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.
Second, the experiment should be carried out under greenhouse conditions.
The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.
By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.
