O cell membrane
Ochloroplast
Ocytoplasm
Omitochondrion
Answers
cell membrane, cytoplasm and mitochondria
Cytoplasm works in plant cells much like it does in animal cells. It provides support to the internal structures, is the suspension medium for the organelles and maintains the shape of a cell.
The cell membrane controls the movement of substances in and out of cells and organelles.
The main job of mitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy.

What forms as a result of the wind's frictional force on water?
Responses
deep sea currents that move in a path similar to the wind currents
surface currents that move in a path similar to the wind currents
deep sea currents that move in a path opposite to the wind currents,
surface currents that move in a path opposite to the wind currents
Answers
Answer:
air or co2
Explanation:
if the wind force is going to be pushed. by air whoch cretaes an atmosphere with water
Answer:
The correct answer is - waves.
The frictional force of the winds is the force with which the winds influence a surface. The smoother a surface is the lesser the friction, and vice versa. The water is a smooth surface, so the winds frictional force is not very big on it, but it is big enough to cause the occurrence of the waves. By constantly influencing the water with their frictional force the winds manage to move and disrupt the surface of the water, with the end result being the waves. Depending on the strength of the winds and the frictional force accordingly to that the waves can be very small, only few mm in height, or can be up to several meters in height.

Activity 1
Reread the last two paragraphs of the “Energy Inventions” article below and highlight evidence that supports or goes against the claims:
Comparing Solutions
Using solar energy and capturing energy from humans are just some of the exciting ways people are using science to solve energy problems. There is no perfect solution, however. Solar energy relies on the sun and doesn’t work as well in the dark or on cloudy days. For example, if you were using your Little Sun to read at night and it ran out of energy, you would need to wait for the sun to come up so that more energy could be captured and transferred to the battery in your light. Just imagine if the next day was very cloudy! Your energy system would not be able to capture very much energy from the sun, so your light would not stay on for long.
The Little Sun lamp and the Hollow Flashlight have something in common: they get energy from somewhere else instead of making it themselves. In fact, that’s true of every object in the universe. Engineers must think about energy sources as they design their inventions. They must find an energy source that will do a good job of transferring energy to the object. The Little Sun lamp gets energy from the sun, while the Hollow Flashlight gets energy from the human body. There are many other possible energy sources to consider. For example, some devices transfer kinetic energy (energy of motion) from wind, water, or even people to power devices! There isn’t a single right way to provide energy when there’s no electrical grid available, and each source has its strengths and drawbacks. Which energy source would YOU choose?
Which claim do you think is most convincing based on the evidence you have gathered so far?

Answers
Answer:
Explanation:In the Atlantic and Northeast Pacific, we use the term "hurricane" to describe severe storms with high-velocity winds that rotate around a central, low-pressure core. The same type of disturbance in the Northwest Pacific is called a “typhoon” and “cyclones” occur in the South Pacific and Indian Ocean.
In order for a hurricane to form, two things must be present: a weather disturbance, such as a thunderstorm, that pulls in warm surface air from all directions and water at the ocean’s surface that is at least 80° Fahrenheit (27° Celsius). Because it is the interaction of warm air and warm seawater that spawns these storms, they form over tropical oceans between about 5 and 20 degrees of latitude. At these latitudes, seawater is hot enough to give the storms strength and the rotation of the Earth makes them spin.
Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. This humid air is then dragged aloft when converging winds collide and turn upwards. At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, causing it to rise as well. As the air far above the sea rushes upward, even more warm moist air spirals in from along the surface to replace it.
As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.
Eventually, hurricanes turn away from the tropics and into mid-latitudes. Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart.
Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms.
Answer:
The surface process that powers the formation of hurricanes is winds, caused by fast rotation of the Earth.The formation of hurricanes requires a combination of different factors, including warm ocean waters, moisture, and atmospheric instability. However, the primary driver of hurricane formation is the Coriolis effect caused by the fast rotation of the Earth.As the Earth spins, it causes the air and water to appear to curve as they move across the surface, which generates areas of high and low pressure. These pressure differences then create winds that move in circular patterns, which are the basis of hurricanes.So, winds, caused by fast rotation of the Earth powers the formation of hurricanes.

It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences
Answers
Answer:
Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Explanation:
Answer:
Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.
During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.
One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.
The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.
