Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all three types of solutions (hypertonic, hypotonic, and isotonic).
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.More about osmosis here: https://brainly.in/question/1213189

Sheets composed of two layers of amphipathic molecules arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center that form in water are called A) micelles. B) liposomes. C) vacuoles. D) bilayer membranes. E) none of the above
Answer:
D) bilayer membranes
Explanation:
Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.
Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.
Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
Polymers are formed via dehydration reactions by molecules. Which of the following best describes a dehydration reaction?
Assembling molecules in either carbonyl or carboxyl functional groups
Assembling molecules in either hydroxyl or carboxyl functional groups
Dissembling molecules in carboxyl functional groups
Dissembling molecules in hydroxyl functional groups
The correct answer is; "Assembling molecules in either hydroxyl or carboxyl functional groups"
Polymers are formed from monomers either by condensation or by addition of monomers.
A polymer is formed by the joining of one or more monomers. This can happen in either of the following ways;
condensationadditionCondensation polymerization involves the loss of a small molecule. When the molecule that is lost is water, we can call it dehydration. Loss of molecules does not occur in addition polymerization.
The two monomer molecules that join to yield the polymer by dehydration must have H and OH moieties in suitable positions for dehydration to occur. A typical example is assembling molecules in either hydroxyl or carboxyl functional groups.

Sometimes the most practical way to do an experiment is not to perform it in an animal, but to look at cell responses in culture. Cells from mice, humans, and other mammals have been used to establish cell culture lines that have been very important for research. You are studying a novel water-soluble mouse hormone. You know cell culture can be a practical model to reveal protein function, so you apply the hormone to yeast cells, but nothing happens. What is a likely explanation for why nothing happened in your experiment
Answer:
Yeast cells likely do not have receptors that bind to this specific water-soluble mouse hormone
Explanation:
Receptors are molecules capable of binding specific signaling molecules (i.e., ligands). For example, steroid receptors can only bind to specific steroid hormones (e.g. estrogen, progesterone). Plasma membrane receptors are protein receptors that bind to water-soluble ligands. These receptors are embedded in the cell plasma membrane and usually contain several transmembrane domains. Examples of cell membrane receptors include G protein-coupled receptors (GPCRs), enzyme-linked protein receptors and ion channel receptors.

Harry is doing a research project on the movement of plants from the ocean to land. He leaned that plants evolved
vascular tissues, which enabled them to pull water from the ground and survive on land. Which is most likely
another adaptation that contributed to the success of land plants?
cell walls?
chloroplasts
waxy cuticle
gametes
Answer:
Waxy Cuticle
Explanation:
Waxy Cuticle retains water. It's the closest in terms of surviving on land. For instance, the plants living in water do not need waxy Cuticle to retain or maintain water. The plants on land requires waxy Cuticle because the temperature is hotter than in the water and they are at higher risk of loosing water during hot seasons and climate. waxy Cuticle aids in their water retention allowing them to adapt to live on land.

At the time Hutton proposed his ideas about the age of rocks, how old was Earth believed to be by most people in Scotland?
Answer:
In the late eighteenth century, when Hutton was carefully examining the rocks, it was generally believed that Earth had come into creation only around six thousand years earlier (on October 22, 4004 B.C.
James Hutton was a Scottish naturalist and geologist who discovered the age of the earth. The earth was believed to be 6000 years old by the Scottish people.
Who was James Hutton?
James Hutton is the father of modern geology and was involved in the discovery of the earth's age and the soil formation from the parent rocks. He made his contribution to discovering the age of Earth based on his observation rather than on assumptions.
Before he discovered the earth age, it was believed by the Scottish people that the planet was six thousand years old. He discovered the process of soil formation by weathering the parent and bog rocks that accumulated as sediments over years and allowed the discovery of the planet's age.
Therefore, it is believed that the earth was 6000 years old.

An object with a mass of 12.59 grams was immersed in water in a graduated cylinder. The volume of the water before was 56.7 mL. After the object was placed in the water, the volume read 63.0 mL. If density = mass/volume, calculate the density of the object to the correct sig figs.
Answer:
[tex]\boxed {\boxed {\sf \rho \approx 2.00 \ g /mL}}[/tex]
Explanation:
The density is the mass per unit volume. It is calculated using the following formula.
[tex]\rho = \frac{m}{v}[/tex]
The mass of the object is 12.59 grams.
The volume was found using water displacement. A known quantity of water was placed in a graduated cylinder (56.7 mL), then the object was added and the water level was recorded again (63.0 mL)The volume of the object is the difference between the initial water volume and the final water volume.
v= final water volume - initial water volume v= 63.0 mL - 56.7 mL v= 6.3 mLNow we know the mass and volume of the object and we can substitute the values into the formula.
[tex]\rho = \frac{12.59 \ g }{6.3 \ mL}[/tex]
Divide.
[tex]\rho = 1.998412698 \ g/mL[/tex]
The original measurements have 4 and 3 significant figures. We always round our answer to the least number of sig figs, which is 3. For the number we found, that is the hundredth place. The 8 in the thousandth place tells us to round the 9 up to a 0 (hundredth place), then the 9 up to a 0 (tenth place), and the 1 up to a 2 (ones place).
[tex]\rho \approx 2.00 \ g/mL[/tex]
The density of the object is approximately 2.00 grams per milliliter.
