Please answer quick!!!

Answers

Answer 1

Answer: theres alot let me explain...

Explanation:

Protein denaturation is what makes eggs solidify, collagen break down and convert to gelatin in slow-cooked meat, fish and chicken become more opaque, and all meats firm up and change color. This is primarily achieved by applying heat, but can also occur in the presence of acidic and basic ingredients.

The Maillard reaction is the primary effect taking place in “browning”, and produces more flavor compounds, resulting in more complex flavors in food that we generally find enjoyable. It involves reaction between amino acids (proteins) and a certain class of sugars called reducing sugars — mostly the monosaccharides, such as glucose and fructose.

Caramelization is a secondary browning effect that occurs in foods with sugar content, even though all browning is often referred to as “caramelizing”. It mostly takes place at higher temperatures than Maillard reaction (with the notable exception of fructose).

Pyrolysis, or thermal decomposition (chemical breakdown) begins at higher temperatures. While caramelization is technically in this category, the main effect of this reaction is carbonization. This is what we generally mean when we talk about “burning” food, even though no combustion has taken place. It’s also what happens when we cause oil to smoke and darken. In small, controlled amounts, this can still provide desirable flavors, such as char on the outside of meat and contributing to “wok hei” in stir frying — the latter of which does involve some combustion.

Acid-base reactions produce carbon dioxide, which creates the rise in quick breads such as biscuits. These often occur at room temperature, but some also don’t occur until higher temperatures — which is how “double-acting” baking powder works.

Gluten formation occurs when you mix flour and water, resulting in stretchy doughs and fluffy baked goods. This occurs easily at room temperature.

Answers

Answer:

Explained below

Explanation:

In chemistry, the process of a chemical change is when the atoms from the reactants rearrange themselves and bond together differently to form one or more new substances with different characteristics than the reactants. Now, after this new substance is formed, the change is called a chemical change.

Now, in cooking Food will undergo a chemical change as it is being cooked. For example, when we boil brown meat, we are causing reactions that change the chemical composition in ways that enhance flavors. Proteins and fibers such as beans when cooked are broken down or undergo denaturation thereby making digestion easier when eaten. Fats like cooking oils are melted while Eggs when boiled are coagulated.

Answer: A tree grows taller.

Explanation: Cells divide for many reasons. They may divide for growth, death, or to replace something. The cells divide when growth is happening, to allow to produce more cells. For example: When a tree grows taller the cells divide so they can produce more cells. The places in trees where these cell divisions happen, are called “Meristems”. This is where all the activity happens.

What is the volume of a 16.24 g sample of magnesium in cubic centimeters? Show a numerical setup and result for credit.

Answers

Answer:

9.34 cm³

Explanation:

From the question given, we obtained the following data:

Mass of magnesium = 16.24 g

Volume of magnesium =.?

To obtain the volume of the magnesium sample, we simply apply the formula for calculating the density of samples. This is illustrated below:

Mass of magnesium = 16.24 g

Density of magnesium 1.738 g/cm³

Volume of magnesium =.?

Density = mass /volume

1.738 = 16.24/volume

Cross multiply

1.738 × volume = 16.24

Divide both side by 1.738

Volume of magnesium = 16.24/1.738

Volume of magnesium = 9.34 cm³

Therefore, the density of the magnesium sample is 9.34 cm³.

What is conserved in physical changes?

Answers

Answer:

The answer is C.

Explanation:

By the Law of conservation of mass, when a element, or product undergoes a physical change, mass always stays the same.

Hope you have a good day.

During physical change the mass of the material remains conserved. The correct option is C.

What is physical change?

Even before to and after a physical change, the material implicated is unique architectural the same.

Physical changes include texture, shape, heat, and the beginning of a change in the state of matter. The texture of a substance influences how it feels.

A physical change is simply a change in appearance. The situation has not changed since the change.

Physical change can be seen in the use of cutting paper, melting butter, dissolving salt in water, and breaking glass.

Mass is neither created nor destroyed in chemical or physical changes, according to the law of conservation of mass.

Physical changes occur when the phage of a substance changes without changing its chemical composition.

Thus, the correct option is C.

What is an element?

An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Explanation:

When you are writing a scholarly paper, you have to conduct a thorough search for source materials online. These sources must be reliable, credible and contain verifiable information. In a project such as writing a paper on the topic 'ocean acidification', the following materials are relevant;

Source 1) 'Functional impacts of ocean acidification in an ecologically critical foundation species,'; Brian Gaylord, Tessa M. Hill, Eric Sanford, Elizabeth A. Lenz, Lisa A. Jacobs, Kirk N. Sato, Ann D. Russell, Annaliese Hettinger; Journal of Experimental Biology 2011 214: 2586-2594; doi: 10.1242/jeb.055939

Source 2) 'Impacts of ocean acidification on marine fauna and ecosystem processes'; Fabry, V. J., Seibel, B. A., Feely, R. A., and Orr, J. C. ; ICES Journal of Marine Science, 65: 414–432; doi: 10.1093/icesjms/fsn048

Answer if you know the answer //Which of the following is an unusual property of water?
A. Its atoms are bound by ionic bonds.
B. It doesn't exist in the gaseous state on Earth.
C. Its charge is balanced evenly around the atom.
D. It's a polar molecule.

Answers

H2O is covalent so A is false.

Water is in clouds so B is false.

Water is polar so C is false.

D is correct H2O has an imbalance of e- so it is polar. [tex]+H-O(-)-H+[/tex]

An unusual property of water is a polar molecule. Therefore, option D is correct.

What is polar molecule ?

When two atoms form a covalent bond but do not share their electrons equally, polar molecules are created. A dipole is created when a portion of the molecule has a slight positive charge and a slight negative charge.

Because the electrons of the hydrogen atoms are "drawn" toward the electrons of the oxygen atom, water (H2O) is a polar molecule. As a result, the hydrogen atoms have a positive charge, whereas the opposite end of the molecule has a negative charge.

Polarity is one of the special characteristics of water because it is composed of polar molecules. Each water molecule has one oxygen atom and two hydrogen atoms (H2O). Polar covalent bonds are created by these compounds. The atoms of hydrogen are positively charged.

Thus, option D is correct.
