the liquid produced by the skin that helps to cool down the body
Answer:
The sweat leaves your skin through tiny holes called pores. When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down.

Answer:
Vasoconstriction is the opposite of vasodilation. While vasodilation is the widening of your blood vessels, vasoconstriction is the narrowing of blood vessels. It's due to a contraction of muscles in the blood vessels. When vasoconstriction occurs, the blood flow to some of your body's tissues becomes restricted

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.

Answer:
Um well the 42 year old man should have reserched what would happen. When pumping liquid oxygen into his grill So that way he could know more of what was happening and the consequinces
Explanation:
Although your question is incomplete a more general answer is provided. pumping of liquid oxygen into fire will lead to Vigorous burning/explosion
Liquid oxygen is oxygen compressed and stored in the form of liquid in cylinders. liquid oxygen is made available for patients with difficult in breathing and it also used for industrial process. Liquid oxygen have a boiling point that is below -238°F. therefore
Some of the hazards associated with liquid oxygen are
when exposed to burning materials ( as seen in the grill ) it will lead to a vigorous burning in the material when in direct contact with human it can cause ; skin and eye irritationsexposure to cold temperaturesHence The hazard associated with liquid oxygen that led to 42 year old male been rushed to the ER is due to the Vigorous burning/explosion associated with the exposure of liquid oxygen to flame.

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.

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.

Un tractor tira de un remolque cargado sobre un camino plano libre de fricción, con una fuerza horizontal constante de 440 N. Si la masa total del remolque y su contenido es de 275 kg, ¿Qué aceleración tiene el remolque? Formula a utilizar : Ʃ F = m . A *
Answer:
1,6 m / s ^ 2
Explanation:
De las leyes de Newton;
Fuerza = masa × aceleración
masa = 275 kg
Fuerza = 440 N
Aceleración = Fuerza / masa
Aceleración = 440N / 275Kg
Aceleración = 1,6 m / s ^ 2

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

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.
