There are quite a few ways to add moisture into the air without a humidifier
A few things that can help add moisture are hanging your clothing to dry. hang drying your damp clothes will add moisture to the air over time as it evaporates and it will make your house smell like fresh clothes.
Another thing is a bath, allow the water to cool off and leave the bathroom door open, the steam will add moisture to the air as the water cools.
This might seem silly but putting bowls or vases of water out on the windowsill on a sunny day mill moistens the air as it evaporates.
You can also get houseplants, moisture evaporates from the leaves and stems of plants. transpiration can help increase the humidity in your home.
not sure if this is the answer you were looking for but if so im glad i could help. have a great day!
In the malate-aspartate shuttle, _____ is reduced to _____ in the cytosol. oxaloacetate; malate aspartate; malate malate; aspartate malate; oxaloacetate aspartate; oxaloacetate
The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.
In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.
During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol. This system enables oxidative phosphorylation in eukaryotes.Learn more: https://brainly.com/question/17216910
Which of the following are phase changes? (Select all that apply.)
melting
gases
sublimation
reactions
Answer:
- melting
- sublimation
Explanation:
A phase change is a, well, change between phases. Solid to liquid. Gas to solid. Etc. Gases is a phase, but not a change. Reactions is a change, but not a phase change. This leaves us with melting (solid to liquid) and sublimation (solid to gas).

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.
There are 3 main ways to measure temperatures, you have Celsius, Fahrenheit, and Kelvins.
Celsius and Fahrenheit are main ways to measure heat in non-scientific terms, althought they are used sometimes when needed.
Kelvins are used for Science as they are precise and can deal with temperatures that are super hot or super cold.
The lowest temperature in Kelvins is 0 degrees Kelvin, also known as Absolute Zero. There are no temperatures above that. So the answer to your question would be Kelvins.

Write a 4-6 sentence paragraph using science vocabulary, full sentences, proper grammar, and details explaining the difference between plant cells and animal cells. Science...
Answer:
Plant cells and animal cells are both eukaryotic cells. They both have a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, cytoskeleton and cell membrane. Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.
Calculate the solubility of copper (II) iodate in 0.16 M copper (II) nitrate. Ksp* is 7.4x10-8 M3. *You should know that the Ksp must refer to the copper iodate because all nitrate compounds are soluble and strong electrolytes!
Answer:
solubility in presence of 0.16M Cu(IO₃⁻)₂ = 3.4 x 10⁻⁴M*
Explanation:
Cu(IO₃⁻)₂ ⇄ Cu⁺² + 2(IO₃⁻)
C(i) ---------- 0.16M 0M
ΔC ---------- +x +2x
C(f) ---------- 0.16 + x ≅ 0.16M* 2x
Ksp = [Cu⁺²][IO₃⁻]²
7.4 x 10⁻⁸M³ = 0.16M(2x)² = 0.64x²
x = solubility in presence of 0.16M Cu(IO₃⁻)₂ = SqrRt(7.4x10⁻⁸M³/0.64M²)
= 3.4 x 10⁻⁴M*
*Note: This is consistent with the common ion effect in that a reduction in solubility is expected. The normal solubility of Cu(IO₃⁻)₂ in pure water at 25°C is ~2.7 x 10⁻³M.
What will a wave look like with high amplitude and long wavelength?
A. Tall and narrow
B. Short and narrow
C. Tall and wide
D. Short and wide
Answer:
A tall and narrow A tall and narrow
Explanation:
Answer:
A. Tall and Narrow
Explanation:
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. But high amplitude waves tend to be short spent and tall narrow linings.

What could be a reason for the difference between the theoretical and experimental heats of reaction
Answer:
Theoretical value is the value a scientist expects from an equation, assuming perfect or near-perfect conditions. Experimental value, on the other hand, is what is actually measured from an experiment. Rarely (in fact never) are these numbers the same.
Take the area of a sheet of paper. I know that the area of a rectangle can be found by multiplying the lengths of both sides together. I can assume an 8.5x11 sheet, so I calculate exactly 93.5 square inches. This is my theoretical value. When I actually do the measurements on my paper, it turns out my paper has been slightly cut on one end, or I’m measuring with a shoddy ruler. Therefore, I might measure only 92.8 square inches. This is my experimental value. See thats it’s close, but not exact.
Expanding on this concept, quantum mechanics is so widely accepted in the scientific community because many theoretical values calculated by mathmaticians concurred with experimental values to many, many decimal places. These would be constants such as Plank’s Constant, energy levels of harmonic potentials, and energy levels of the hydrogen atom.
Explanation:
Theoretical result is based on information and mathematics. Trials or experiments are the foundation of experimental result. What ought to occur is theoretical probability. What actually occurs is experimental probability.
What is difference between theoretical and experimental result ?The definition of theoretical probability. It is not necessary to do the experiment and then analyze the findings for theoretical probability. The theoretical probability, however, represents what you anticipate will occur in an experimnet.
In experimental probability, information is gathered via repeated experimentation. In theoretical probability, data is gathered without doing the experiment by taking into account every possibility that has a chance of occurring.
Thus, difference between the theoretical and experimental heats of reaction the incomplete combustion may result in the formation of carbon and carbon monoxide instead of carbon dioxide and water.

A clasping handshake may be used as an analogy for an enzyme-catalyzed reaction because it represents the specific manner in which an enzyme ________. folds to form secondary and tertiary structures interacts with water binds substrate is denatured by low pH
A clasping handshake is similar to the way in which enzymes bind to substrates in enzyme-catalyzed reactions.
Enzymes are biological catalysts that speed up the rates of biological reactions by lowering the minimum energy required by reactants in order to arrive at products.
Enzymes are able to achieve this feat by substrate-enzyme binding. The substrate binds to the enzyme in its active site, becomes products, and the products are released from the active site of the enzyme. Thus, the enzyme is free for the binding of another substrate.
