the two cells below are hypothetical cells with a concentration of 100 mosm of k inside the cells and containing only leak channels for k within the membrane. each cell is placed into a different solution containing different concentrations of k in the extracellular fluid. which of the two cells below has a higher permeability to k and why? choose the best answer.

Answer:Humans

Explanation: Humans are vertebrates that belong to the Kingdom Animalia. Eukaryotes are organisms that possess a nucleus enclosed by the nuclear membrane.

They are strong oxidizing agents and are readily reduced to the X– ions, and so the halogens form numerous ionic compounds.

The halogens are a group in the periodic table consisting of six chemically related elements: fluorine, chlorine, bromine, iodine (I), astatine, and tennessine, though some authors would exclude tennessine.

The halogens have low melting points and low boiling points. This is a typical property of non-metals. Fluorine has the lowest melting and boiling points. The melting and boiling points then increase as you go down the group.

The halogen elements are the six elements in Group 17 of the periodic table. Group 17 occupies the second column from the right in the periodic table and contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

Explanation: because the lactose sinks into it

Benedict's reagent does not typically react with lactose. Benedict's reagent is a solution of copper(II) sulfate that is used to test for reducing sugars, including glucose and fructose.

When a reducing sugar is present, the reagent will change color from blue to green, yellow, or brick-red, depending on the amount of sugar present. However, lactose is not a reducing sugar, so it will not react with Benedict's reagent and will not cause a change in color. Lactose, however, is not a reducing sugar, so it will not react with Benedict's reagent and will not cause a change in color. To determine the presence of lactose in a sample, a different test, such as the lactose tolerance test, must be performed. In this test, the patient drinks a solution containing lactose and then has their blood glucose levels measured at intervals to determine how well they can digest lactose.

For the rock cycle to take place, energy from the sun and heat from the Earth are both necessary, and they each contribute to the different geological processes that cause rocks to change shape through time.

The production, disintegration, and reformation of rocks throughout the course of geological time is referred to as the rock cycle. It encompasses the alteration of igneous, sedimentary, and metamorphic rocks through procedures like cooling, erosion, sedimentation, heating and pressure, melting, and recrystallization.

According to Tori, the sun's energy is essential for the rock cycle to occur. This is because many processes that cause rocks to alter form, such weathering and erosion, are powered by the sun's light. Rocks erode as a result of water evaporating due to the heat of the sun and falling as precipitation. The wind is generated by the sun's energy and can carry and deposit sediment, adding to the cycle.

Jessica claims that without the heat from the Earth, the cycle could not exist. This is due to the fact that the melting and solidification processes that are essential to the rock cycle are driven by the heat of the Earth. The heat of the Earth causes rocks to melt, creating magma that can then solidify to create igneous rocks. The heat also fuels metamorphism, a process in which rocks undergo heat and pressure transformations to take on new forms.
