Answer:
Exosmosis
Explanation:
Osmosis is the process of movement of water down the concentration gradient across a semi permeable membrane. Exosmosis is movement of water outside the cell through osmosis. Here, the water movement is shown to occur from the region of its higher concentration (inside the cell) to that of lower concentration (outside the cell). Plasma membrane serves as semi permeable membrane. So, the process is called as "exosmosis" with respect to cell.
The process where water flows out of a cell when the water concentration inside is higher than outside is called osmosis, a type of passive transport. This movement of water occurs through a semi-permeable membrane and is facilitated by proteins called aquaporins. It aims to balance water concentration inside and outside the cell.
Explanation:The method of molecular transport you've described, where water flows out of a cell when the water concentration inside it is higher than the water concentration outside, is known as osmosis. This process is a type of passive transport as it doesn't require any energy, instead, it relies on the natural tendency of water to move from regions of higher concentration to areas of lower concentration, via a semi-permeable membrane, in order to achieve balance.
This transportation is facilitated by aquaporins, which are proteins that form water channels in the cell membrane, enabling water to move more easily. Cells often expose themselves to an isotonic environment – one where the concentration of solutes is equal both inside and outside the cells, which keeps the concentration of water molecules the same as well and helps cells maintain their normal shape and function.
But when cells are placed in a hypertonic solution – one where the concentration of solutes is higher outside the cell compared to inside, water moves out of the cell to balance the concentrations, causing the cell to shrink, which is known as plasmolysis.

Explanation:
If Luke pushes his sister in a wagon down the driveway that is 14 meters long and it takes 22 Newtons of force, how much work did he do? 20 points !!
Answer:
[tex]308 N\cdot m[/tex] or 308 J
Explanation:
Work in physics is done when an object is moved due to an applied force. But you need to remember that work is only done if there is movement parallel to the direction of the force applied.
Work can be computed with the formula:
W=Fd
Where:
F = Force
d= distance
So your problem gives you:
F = 22 N (Newtos)
d = 14 m (meters)
All you need to do is plug in the values and multiply:
W = F x d
W = 22N x 14m
W = 308 N-m or 308 J (Joules)

4. How is salinity affected?
(A) evaporation increases
(B) freezing increases
(C) melting increases
(D) precipitation increases
5. How is density affected when
(A) the temperature increases
(B) the depth increases
(C) the latitude increases
(D) the salinity increases
1:
At sea level, the air that surrounds us presses down on our bodies at 14.5 pounds per square inch. You don't feel it because the fluids in your body are pushing outward with the same force.
Dive down into the ocean even a few feet, though, and a noticeable change occurs. You can feel an increase of pressure on your eardrums. This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by 14.5 psi.
2:
Two layers of water result would be; Mixed layer and deep water, Also the Thermocline separates them.
Description
A thermocline is a thin but distinct layer in a large body of fluid in which temperature changes more rapidly with depth than it does in the layers above or below. In the ocean, the thermocline divides the upper mixed layer from the calm deep water below.
3:
(A)
The deeper the waters, the lower the temperatures since. The only reason this works is since sunlight isn’t able to penetrate to deeper water due to the fact it gets attenuated bc of diffusion and scattering.
(B)
Temperature of water are lower with increasing attitude due to the fact that the differential angle in which the sunlight usually would hit, would hit earth at a different angle.
4:
(A)
It would increase salinity since, Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean.
(B)
In cold, polar regions, changes in salinity affect ocean density more than changes in temperature. When salt is ejected into the ocean as sea ice forms, the water's salinity increases. Because salt water is heavier, the density of the water increases and the water sinks.
(C and D)
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
5:
(A)
Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. ... Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water.
(B)
The water molecules pack together tighter as pressure increases -the pressure increase with depth, due to the weight of the water above, and causes the greatest density changes in seawater with depth (greater than the density changes due to temperature and salinity changes).
(C)
The density decreases
(D)
Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water. ... Temperature has a greater effect on the density of water than salinity does.

2. What role does gravity play in the water cycle?
3. Describe the flow of one molecule of water through the water cycle, beginning in the ocean.
Answer:
1 Sun/ Solar
2- Allowing precipitation to fall
3- The water in the ocean gets enough sun one day and it evaporates and forms into a cloud. The cloud then relocates over the nearby land. The cloud becomes too dense with water vapor and gravity carries the water down as precipitation, most likely rain or snow. It then flows through little streams and back into the ocean to restart the process.
Answer:
1. In my point of view, I think the energy that causes evaporation comes from the sun. The sun is what heats the water and makes tiny vapors evaporate into the air which forms clouds.
2. Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. It basically pulls water and precipitation downhill until it connects to a river which eventually runs into an ocean. It allows precipitation to fall.

To make a 25% sugar syrup, we need to determine the amount of water required to dissolve the sugar.
We know that we have 50 grams of sugar, and we want the sugar to be 25% of the total mixture. This means that the remaining 75% will be water.
Let's set up an equation to find the amount of water needed:
Sugar + Water = Total Mixture
50g + Water = Total Mixture
Since we want the sugar to be 25% of the total mixture, we can express it as a decimal fraction:
25% = 0.25
Now we can rewrite the equation as:
50g + 0.25(Total Mixture) = Total Mixture
Next, we want to solve for the amount of water needed. To do this, we'll isolate the Water term:
0.25(Total Mixture) = Total Mixture - 50g
0.25(Total Mixture) - Total Mixture = -50g
0.25(Total Mixture) - 1(Total Mixture) = -50g
-0.75(Total Mixture) = -50g
Dividing both sides by -0.75:
Total Mixture = -50g / -0.75
Total Mixture ≈ 66.67g
Now, to find the amount of water needed, we'll subtract the weight of the sugar from the total mixture:
Water = Total Mixture - Sugar
Water = 66.67g - 50g
Water ≈ 16.67g
Therefore, to make a 25% sugar syrup with 50g of sugar, you would need approximately 16.67g of water.

In figure 33-5, identify the four chambers of the heart. then use them to describe the path through which blood travels in the heart.
Answer:
You did not provide a figure, but you can refer to the attached picture and match it up with your figure.
The heart has 4 chambers. It has the left and right Atrium (plural is atria) and the left and right ventricle.
The blood FROM the body going towards the heart is deoxygenated. It empties into the RIGHT ATRIUM. From there, it goes through the tricuspid valve then empties into the RIGHT VENTRICLE. The right ventricle then pumps the blood up into the pulomonary artery, and goes towads the lungs to be oxygenated. The oxygenated blood then leaves the lungs via the pumonary vein and it empties the blood into the LEFT ATRIUM. From there the blood goes through the bicuspid valve and pours into the LEFT VENTRICLE. The left ventricle pumps the blood up the aorta and from there, it goes to the different parts of the body.
In summary:
BODY ---> RIGHT ATRIUM ---> RIGHT VENTRICLE ---> LEFT ATRIUM ---> LEFT VENTRICLE
Take note though that this is the pathway with regards to ONLY the chambers.

8. Which process is responsible for destroying shorelines along seawalls near urban areas?
O A. Groundwater infiltration
O B. Erosion
O C. Deposition
O D. Eutrophication
Answer: B. Erosion
Explanation:
Erosion is a process of removal of top and sub-surface layers of the soil and depositing them to other location. It is caused by physical agents such as water, wind and others.
Among the options given, erosion is the correct option this is because of the fact that erosion due to water will remove the sand and seawalls present on the shorelines. This can only be caused by seawater with high speed water currents.
Erosion is the process responsible for destroying shorelines near seawalls in urban areas, as it is exacerbated by human-made structures that interrupt natural sand replenishment. The correct option is B.
The process responsible for destroying shorelines along seawalls near urban areas is erosion. This happens when natural littoral processes like longshore drift are disrupted by human-made structures such as groins or seawalls. These structures can prevent sand from naturally replenishing shorelines and may lead to increased erosion downstream from these barriers. Erosion near the toe of seawalls is specifically caused when the natural replacement of sand is inhibited, leading to a loss of beach material and the decay of coastlines. This issue is often exacerbated in urban areas where coastal development pressures are high, and human interference with shoreline processes can be significant.
