complete th table below by citing the deffirences between an epicenter and hypocenter based on their characteristic
Answer:
The epicenter and hypocenter are two important points in causing earthquakes.
Both the epicenter and hypocenter are different from each other in the following basis:
Location: Hypocenter is present within the earth surface where an earthquake rupture starts and the epicenter is located in the earth's crust just above the hypocenter where a seismic rupture begins.
Associated waves: Seismic waves propagate from the hypocenter caused by seismic velocity and rock density which reaches the epicenter where P and S waves hit the surface of earth.
What is the difference between microscopic and macroscopic ecosystems?
Answer:
Microscopic ecosystems consist of the organisms that are microscopic in nature or that which cannot be seen by naked eyes. They are mostly found in soil oceans and some are even living in association with plant and animals.

They are mainly of 3 types:
Terrestrial Aquatic Aerial.How does carbon flow between photosynthesis and cellular respiration?
A. Photosynthesis produces carbon dioxide from glucose made by the process of
cellular respiration.
B. Cellular respiration produces carbon dioxide from glucose made by the process of
photosynthesis.
C. Photosynthesis produces carbon dioxide from ATP made by the process of cellular
respiration
D. Cellular respiration produces carbon dioxide from ATP made by the process of
photosynthesis.
Answer:
B. Cellular respiration produces carbon dioxide from glucose made by the process of
photosynthesis.
Explanation:
Photosynthesis is a process by which the autotrophic cells make food by absorbing and converting solar energy into chemical energy.
Cellular respiration is a process in which the oxygen molecules couple with food nutrients to generate energy, CO₂ and water.
The correct answer is:
Option B. Cellular respiration produces carbon dioxide from glucose made by the process of photosynthesis.
This can be explained as:
Photosynthesis uses the light energy from the sun to convert them into chemical energy.The reactants of photosynthesis are sunlight, carbon dioxide and water molecules and the products produced are glucose and oxygen molecules.The glucose produced by the process of photosynthesis is then utilized in cellular respiration to produce carbon dioxide.Therefore, cellular respiration utilizes the glucose produced from photosynthesis.

1. Krista is conducting an investigation to determine how much fertilizer is best for her sunflower plants. She uses five plants and gives each a different amount of water for six weeks. Each week, she measures the height of each plant. She records her findings in a chart.
Answer the following:
1a. What are the independent and dependent variables?
1b. What should she record in the chart?
1c. What kind of scientific investigation is this example?
Answer:
1a. Independent variable: WATER
Dependent variable: HEIGHT
1b. the height of each plant every week
1c. Experimental investigation
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated by the experimenter. In this case, the independent variable is the AMOUNT OF WATER given to each plant.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is HEIGHT.
(1b) In an experiment, the dependent variable is the variable that is recorded. Hence, in this experiment, the HEIGHT of each plant every week is recorded in the chart.
1c) 1c. This investigation is a type of EXPERIMENTAL INVESTIGATION because it involves testing how the independent variable affects the dependent variable.

Urey and Miller cooked a "Primordial soup" with Hadean gases, water and electricity to make ___, ___, ___, and ___.
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
what chemical substance is produced by the mitochondria

In a block and tackle system each pulley that you add will all the force to be ____.
1. decreased
2. increased
Answer:decreased
Explanation:
Answer:
Decreased
Explanation:
When you add extra pulleys, the minimum force that is needed to be given off by the person pulling lowers. For example if you have one pulley and pull on it, you require more force to move the object than your friend with two pulleys. He requires half the force that you do to move the object.

Can cells survive without support of other cells?
Answer: There are literally countless single celled life forms all over the planet and every creature living is the descendant of single celled organisms. So the answer to your question as written is no, a cell can survive perfectly fine on its own, without the support of other cells, so long as its in a favorable environment.
Explanation:
Answer: No
Cells in bodies of living organisms are designed to help one another, so cells can not live/survive without support of other cells. They work in unity to help our body.

Human powered generators are the best source for the rescue team. We cannot always depend on the sun. What if the sun is not out that day? What if it's a rainy day? What if the sun is what's causing the rescue team to come out? Human powered generators are sometimes untrustworthy, but at the same time we know that at least it's a step away. We don't have to wait all-day for the sun to help out. Of course, the energy from the sun is always going to be there and won't cause anybody hurt, harm, or danger, but at the same time we can always convert to human powered generators and they'll work just as perfect.
Hope this helps, have a great day!
Which statement describes a difference between the lower mantle and oceanic crust? O The lower mantle is closer to Earth's surface than oceanic crust is. O The lower mantle is found closer to sea level than oceanic crust is. O The lower mantle experiences more pressure than oceaníc crust does. The lower mantle has a more tarry consistency than oceanic crust does.
Explanation:
The difference between the lower mantle and the oceanic crust is first their respective locations, pressure and temperature-- the pressure and temperature increases with depth in the earth this the mantle is more hot and under great pressure than the crust. hope this helps
The statement describes the main difference between the lower mantle and an oceanic crust is that the lower mantle experiences more pressure than the oceanic crust. Thus option C is correct.
What are the lower mantle and an oceanic crust?The lower mantle is the middle layer of the earth which lies in between the crust and the core. This is the middle layer of the earth in which the temp and pressure are so high because of the absence of air. The oceanic crust is the uppermost layer of the earth's crust in which marine plants grow.
The main difference between these two is that the mantle crust experiences more pressure than the oceanic crust because it is present in more depth. As we go in depth of the earth the temp and pressure arise because of the unavailability of oxygen.
So by reading this data the correct statement which exactly describes the difference between the mantle and the oceanic crust is statement C.
