Answer:
Under hypotonic conditions.
Explanation:
If the extracellular fluid has lower osmolarity than the fluid inside the cell, it’s said to be hypotonic—hypo means less than—to the cell, and the net flow of water will be into the cell.
A substance can enter a cell through diffusion if there is a concentration gradient, the substance can pass through the cell membrane, and if necessary, specific protein channels are available in the cell membrane. Diffusion is a passive form of transport that does not require energy from the cell. External conditions like solvent density and system temperature can also affect the rate of diffusion.
Explanation:
A substance is likely to enter a cell through diffusion under certain conditions, including the existence of a concentration gradient, the ability of the substance to pass through the cell membrane, and the presence of specific protein channels in the membrane. Diffusion moves a substance from an area of higher concentration to an area of lower concentration until the concentration is equal across the space. This is a form of passive transport, meaning it doesn't require any energy from the cell.
For example, in an organism, gases, lipids, and water pass through the cell membrane easily, often using protein channels known as aquaporins for water. But polar molecules like glucose, amino acids, and ions may not easily pass through. These molecules often rely on facilitated transport, moving down a concentration gradient through set protein channels in the membrane, which does not require energy.
Other factors can also affect the rate of diffusion, including solvent density and system temperature. A denser medium or lower temperatures can slow the rate of diffusion, while a less dense medium or higher temperatures speed it up. So, the conditions in which the cell exists also play an integral role in whether a substance can enter a cell through diffusion.

1. Where does the energy that causes evaporation come from
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.

Answer:
C
Explanation:
A totipotent cell can differentiate into any type of cell and is the potency with the highest differentiation potential. It is then followed by pluripotency, multipotency, then unipotency. The ability of a cell to have differentiation potential is governed by the ability of its silenced genes to be easily reactivated.
Describe how minerals form in diagram C
Answer:
Explanation:
C is a volcano.
A volcano is as a result of igneous activities.
Volcanoes are landforms formed by the extrusion of magma on the earth crust.
Magma that reached the crust is called a lava and it is made up of molten rock minerals.
When the lava cools, it forms the rocks we see on the crust.
The mechanism by which minerals forms in a melt is known as differentiation. Differentiation is the process by which minerals separates from an originally uniform mixture. As temperature varies within the earth, new minerals forms by combining elements and others are broken down.
In a Volcano, the melt is the mineral soup. The melt is at a very high temperature. As it rises through the vent to the surface, temperature decreases very rapidly. When temperature reduces rapidly, it is difficult for large minerals to form. Minerals crystallise out of the melt according to the Bowen's reaction series and the composition of the melt.
We must note that, as the melt rises through the crust, it assimilates some crustal materials. Some of these materials can change the original composition of the melt as it rises. If such a melt orginates from the mantle, it mixes with crustal rocks and forms a rock bearing some mafic and felsic minerals.
It is typical to find fine grained rocks that lacks crystals in such a place. This is because the cooling of the melt was rapid and crystals could not form properly.
Minerals are formed when transition metals bond with other elements, often through the ions' formation process. Examples of these processes include the creation of mineral crystals in bone through the bonding of calcium and phosphorus, and the formation of ionic compounds. Ionic compound formation typically involves metals losing electrons and nonmetals gaining electrons to achieve a stable electron configuration.
Explanation:Minerals such as malachite, azurite, and proustite form when transition metals bond with other elements and create complexes. This process involves the formation of ions. For instance, atoms may lose or gain electrons, forming cations (positively charged ions) or anions (negatively charged ions) respectively. An example of this is the sodium atom losing electrons to form a sodium ion, or calcium forming a calcium cation.
In the specific case of calcium, it can bond with elements such as phosphorus to produce mineral crystals found in structures like bones. Another example of a chemical reaction involving calcium is the formation of solid calcium hydroxide from the reaction of solid calcium oxide with liquid water.
The formation of ionic compounds, wherein metals lose electrons and nonmetals gain electrons to achieve an octet, is also crucial in the formation of minerals. Lewis symbols often illustrate these electron transfers.

An increase in wastes would be sent to each cell, and they would become infected. C. Oxygen would not be removed, and the muscles would not be able to move. D. No energy would be available to the cells, and the organism would not be able to move.
Answer:
D. No energy would be available to the cells, and the organism would not be able to move.
Explanation:
Function of digestive system is to breakdown the nutrients into the simpler elements which in turn are absorbed by cells. These simpler elements, such as glucose, amino acids etc, serve enter the cellular respiration. Cellular respiration is the process of complete oxidation of nutrients to drive ATP synthesis. If digestive system breaks down, processes of digestion of food and cellular respiration would not occur. This would hamper the supply of ATP to muscles and the organism will not be able to move in absence of muscle movement.

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.

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.

was introduced by John Ray
was introduced during the Renaissance
was introduced by the Greeks
Answer: The first case of using two words as a scientific name was introduced by John Ray, he was an english naturalist of the XVII century. He used complex terms composed by two words to describe the species.
Explanation:
The use of two words as a scientific name was introduced by Carl Linnaeus, who established the binomial nomenclature system in the 18th century. This system, using Latin or Greek words for genus and species, provides a unique and universally recognized name for each species.
The first case of using two words as a scientific name was introduced by Carl Linnaeus, who established the binomial nomenclature system. The binomial naming system consists of two unique names: the genus name and the species name. Both are crucial in scientifically identifying and classifying species to avoid confusion caused by common names, which may vary by region.
Before Linnaeus, the use of common names was prevalent, but it was prone to errors and inconsistencies due to regional variations. Linnaeus' system uses two Latin- or Greek-form words: the first name representing the genus and capitalized, and the second name indicating the species in lower-case. For example, Homo sapiens is the binomial name for humans, and Cyanocitta cristata is the binomial for the North American blue jay.
While John Ray contributed significantly to the definition of species and Caspar Bauhin took steps towards a two-word naming system, the binomial nomenclature was solidified and popularized by Linnaeus in the 18th century, ensuring a uniform and global recognition of species.
if the water concentration inside a cell is higher than the water concentration outside the cell, water flows out of the cell. this method of molecular transport is called
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.

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)
