What type of cell was she most likely observing and what evidence supports this claim?
O A plant cell because it has a cell wall.
A fungal cell because it has a vacuole.
O A plant cell because it has a vacuole.
O A fungal cell because it has no chloroplasts.
Answer:
A Comparison of Cells Commonly Seen in Lab
Bacteria: prokaryotic. Very small. No nucleus, no chloroplasts, no mitochondria. Do have a cell wall.
Plant cells: eukaryotic. Relatively large. Have a nucleus, have mitochondria, sometimes have chloroplasts. Have a large central vacuole and a cell wall.
Animal cells: eukaryotic. Relatively large. Have a nucleus and mitochondria. Never have chloroplasts. Lack a cell wall, and have no central vacuole.
...
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
This cell was alive and at 1000x magnification when it was photographed.

Answer:
C. predation
Explanation:
The limiting factor that is being displayed when a fox chases a pika is predation.
Limiting factors can be referred to as those features in the environment which actually leads to the limitation in the growth, distribution or availability/abundance of an organism or population of organisms in an ecosystem.
In the predation limiting factor, as the population of the prey decreases, the population of the predator starts to decrease as well. In other words, we can say that one factor limits the growth of the other factor.

Why must digestion happen before absorption can take place?
Answer:
digestion breaks down the larger food particles into smaller ones so that they can be absorbed, large pieces can not be absorbed.
Explanation:
think of when you are filtering something with a sieve, only the smaller particles pass through the sieve the larger particles remain on top.

Answer:
The kinetic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of molecules moving a little farther apart.
Explanation:
The kinetic-molecular theory explains the changes of state in the following way: When a solid is heated, its particles increase their kinetic energy, so that the vibration becomes more and more intense until, having reached the melting temperature, they become so weak that the particles acquire freedom of movement, that is, if we increase the temperature of a solid material system, its molecules will move faster and the average distance between them will increase, the cohesion forces decrease and there will come a time when these forces are incapable to keep the molecules in fixed positions, the molecules can move.

1. Why does the moon go through Phases?
I
2. Why do we experience solar and lunar eclipses?
3. What is the underlying reason the Earth goes through
Seasons?
Explanation:
1.The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days "catching up" because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.
2.
An eclipse is the result of the total or partial masking of a celestial body by another along an observer's line of sight. Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.
3.Why Do We have Seasons?
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can.
Why Do the Seasons Change on Earth?
Two things cause the seasons to change. First, the Earth moves around the Sun. Second, the Earth has a tilted axis of rotation.
The Earth spins around an axis. This imaginary line extends from the South Pole to the North Pole. But the Earth’s axis is not vertical. It’s actually tilted at an angle of 23.5°. The planet is always tilted in the same direction as it orbits the Sun.
Los procesos de respiración aerobia celular y fotosíntesis, procesos considerados indispensables para la vida en la tierra, de los que es correcto afirmar que Son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas. La respiración celular sólo la realizan los seres eucariotas del reino de los vegetales. Ambos son realizados por los seres considerados eucariotas. Ambos son realizados por eucariotas pertenecientes al reino de los vegetales
Respuesta:
Las opciones correctas son: a) son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas; y d) ambos son realizados por eucariotas pertenecientes al reino de los vegetales.
Explicación:
La fotosíntesis y la respiración celular son procesos de carácter antagónico porque la fotosíntesis es anabólica y la respiración celular es catabólica. La fotosíntesis consiste en la producción de moléculas complejas a partir de moléculas simples (proceso anabólico), mientras que en la respiración celular se degradan moléculas complejas y se las convierte en moléculas más simples (proceso catabólico).
Ambos procesos son realizados por los eucariotas del reino de los vegetales, pero los eucariotas del reino animal sólo realizan respiración celular, ya que no tienen cloroplastos. Esta diferencia tan importante existe porque los animales pueden moverse para conseguir comida (heterótrofos), mientras que los vegetales necesitan producir sus propios nutrientes haciendo uso de la fotosíntesis (autótrofos). Más allá de esta diversidad, todos los eucariotas realizan respiración celular para producir energía en forma de ATP.

Erosion, transportation and deposition change the earth surface
Answer:
The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land. Water's movements (both on land and underground) cause weathering and erosion, which change the land's surface features and create underground formations.

Why is the defense attempting to exclude OJ’s domestic Violence history from the court case?
Answer:
The celebrity of the defendant, the other major players, and the case itself had, and continues to have, society as a whole discussing domestic violence and the effectiveness of our laws that deal with this area of criminal law. Since the commission of the crimes in June of 1994, the Simpson' case brought to the forefront the issue of what role evidence of prior domestic violence should play in criminal prosecutions. In addition to the forensic evidence which the Los Angeles prosecutors relied upon to attempt to convict Mr. Simpson, the theory of the prosecution's case rested on the proposition that Mr. Simpson committed the murders against his former wife, Nicole Brown Simpson (hereinafter Ms. Brown), and her friend, Ronald Goldman, because of jealousy, obsession, and the need to dominate Ms. Brown. The prosecution's case rested entirely upon circumstantial evidence, and as such, the prosecutors sought to introduce evidence of Mr. Simpson's past abusive conduct toward Ms. Brown to establish the identity of the perpetrator and his motives to commit the brutal crimes. The prosecution argued that the history of domestic violence and prior threats were probative evidence of Mr. Simpson's motive, intent, plan, and identity as the killer. According to Los Angeles District Attorney Gil Garcetti, the trial judge's ruling on the admissibility of this evidence was the "most critical ruling" that the Court would make in the case The prior conduct which the prosecution wanted to introduce on its direct case included acts of physical beatings upon Ms. Brown by Mr. Simpson, some of which were documented by photographs showing Ms. Brown's injuries. Other incidents included an episode in which Mr. Simpson had thrown Ms. Brown out of a moving car; a 1989 assault for which Ms. Brown had been hospitalized due to her injuries; Mr. Simpson's 1989 no contest plea to spousal abuse for which he was ordered to undergo counseling and pay a fine; letters of apology for the abuse written by Mr. Simpson to Ms. Brown; Mr. Simpson's repeated threats to kill Ms. Brown; a 1993 recording of a "911" telephone call made by Ms. Brown to the police, during which the voice of Mr. Simpson was heard making threats and shouting obscenities at Ms. Brown; evidence that Mr. Simpson was stalking Ms. Brown, and that shortly before her death, Ms. Brown had made contact with a battered women's shelter help-line; and many other instances of actual and threatened violence committed by Mr. Simpson against Ms. Brown dating back to 1977. In January 1995, Judge Lance Ito, who presided over the murder trial, ruled that much of the domestic violence history would be admissible on the prosecution's direct case, including the 1993 "911" tape-recorded telephone call by Ms. Brown. The evidence was admitted to provide the jury with an appreciation of the "nature and quality" of the relationship between Mr. Simpson anji Ms. Brown, and to aid in establishing motive, intent, plan, and identity of the killer.

Explanation:
Evaporation of water from oceans at the equator is an example of an interaction between the cryosphere and hydrosphere. So, the correct option is (E).
What are Hydrosphere and Cryosphere?The cryosphere is define as the part of Earth's climate system which includes solid precipitation, snow, sea ice, lake and river ice, icebergs, glaciers and ice caps, ice sheets, ice shelves, and seasonally frozen ground. The word is derived from the Greek word 'kryos' which means frost or icy cold.
The hydrosphere is defined as the sum of the Earth's water such as seas, land, surface, and air. About 71 percent of the Earth's surface is covered by water where only three percent is fresh water. Even less can be used as drinking water. They both interact at equator in the form of Evaporation.
