Solar energy is the most abundant energy resource on earth about 173,000 terawatts of solar energy strikes the Earth continuously. That's more than 10,000 times the world's total energy use. 5. The first silicon solar cell, the precursor of all solar-powered devices, was built by Bell Laboratories in 1954.

The body absorbs nutrients through the small intestines. The blood transports these nutrients to every cell in the body. The blood also carries oxygen to every cell. The cells use the nutrients and oxygen to supply the energy the body needs. What three body-systems are working together in this situation?
A. nervous, digestive, and circulatory systems
B. digestive, circulatory, and excretory systems
C. respiratory, circulatory, and digestive systems
D. circulatory, immune, and respiratory systems
Answer:
(C) Respiratory, circulatory, and digestive systems
Explanation:
In this example, the respiratory system is being used because oxygen specifically is being transported through the bloodstream to the body. The way that oxygen enters the body and is stored until the blood can pick it up is of course through breathing! Another word for breathing is respiration and this involves the lungs, which all points to the respiratory system.
The circulatory system is being used due to the fact that blood specifically is being used to transport these nutrients and oxygen around the body. Blood passes through veins and arteries through the body and is all a part of the circulatory system!
Lasty, the digestive system is being used because the small intestines are absorbing nutrients and the intestines are where a majority of digestion takes place (hence, the digestive system).
Answering questions like these, or any question about body systems, means you need to know about what each system is and what it does. It can help to think about what body parts each system includes and one or two key words involved with that system. Ex. CIRCULATORY: blood. CARDIOVASCULAR: heart, capillaries, veins, arteries, pumping blood
In the given situation, the respiratory, circulatory and digestive systems are working together.
Working of the body systems:In the given case, as oxygen is mediated through the bloodstream in the body, therefore, respiratory system is being used. The blood is being used to mediate oxygen and nutrients all through the body, therefore, circulatory system is being used.
Blood is moved via arteries and veins throughout the body, which is a component of circulatory system. In the given case, as the small intestines are used to absorb nutrients, and it is the place where maximum of the digestion process takes place, therefore, digestive system is also taking part in the process.
Thus, the correct answer is option C.

Explanation:
Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma.
4. Predict Examine the photo of a cell cycle
phase below. Then draw, label, and describe
the phase that follows it.
Answer:
G1 phase of interphase
Explanation:
Mitosis is a type of cell division in which a single cells divides to form two daughter cells.
The sequence of events that occurs in mitosis are as follows:
Interphase G1---> Interphase S ----> Interphase G2---> prophase--------------------------->metaphase---> anaphase -----> telophase----> cytokinesis
With cytokinesis the cell finally divides into two daughter cells and the cycle again continues and follows the sequence mentioned above.
So, it can be seen from the above sequence that after mitosis is complete with cytokinesis the daughter cells will now enter in the G1 phase of interphase.

How will the dam most likely affect the ecosystem around the river?
Answer: Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.

Integrate Information: Which two ideas of Lamarck contributed the most to Darwin’s theory of evolution?
Answer:
Jean Baptiste Lamarck (1744-1829) is one of the best-known early evolutionists. Unlike Darwin, Lamarck believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human "perfection." Species didn't die out in extinctions, Lamarck claimed.

anaphase:
-chromosomes divide into two sets
-each half or set is pulled away to opposite sides of the cell
telophase:
-two nuclear membranes begin to form
-cells begin to separate
cytokinesis:
-cytoplasm divides
-two daughter cells with the same number of chromosomes are created

Sea anemones can reproduce sexually or asexually. What would be the most likely advantage a sea anemone would have to reproduce sexually over reproducing asexually?
Answer:
Re-producing sexually will allow the sea anemones to give their offspring a more diverse gene pool and can mitigate the risks of a genetic disorder being spread to the offspring because the bad gene has a higher chance become recessive if the gene of the anemone it mates with is more dominant (meaning it wouldn't allow the "bad" gene to show in the offspring) whereas otherwise, the offspring would have the same issues the mother did (assuming it had a bad gene to begin with).

How does lake effect snow affect the human population living in New York? Support your claim with evidence from the article. Then, explain why the evidence supports your claim. You need a paragraph (5-8 complete sentences).
Answer:
This causes some lake water to evaporate into the air and warm it. This warmer, wetter air rises and cools as it moves away from the lake. When it cools, it dumps all that moisture on the ground. If it's cold enough, that moisture becomes snow.
Explanation:

The effect of the lake effect snow is to become difficult to travel, the snow cover their cars and other things.
What is the lake effect snow?Lake effect snow occurs when cold, below-freezing air travel over a lake's warmer water.
As a result, some lake water evaporates, warming the air.
Then, the warm air moves away and after cooling it become snow.
The areas in effect by lake effect snow is called Snowbelt.
