Explanation:

A carbohydrate is formed from carbon, hydrogen and oxygen. These three elements are combined in every carbohydrate.

Even though carbohydrates are composed of only these three atoms, the number of atoms of these elements in each carbohydrate as well as the spatial arrangement of these atoms in each carbohydrate is not the same.

This means that different carbohydrates contain different number of carbon, oxygen and hydrogen atoms which are arranged in different ways in space. This gives room for the existence of many different types of carbohydrates all consisting of carbon, hydrogen and oxygen atoms.

The information regarding the different carbohydrates that should be formed is explained below.

It should be created from carbon, hydrogen, and oxygen. It should be combined with every carbohydrate. Still, carbohydrates should be comprised of only these three atoms, so the no of atoms of these elements in every carbohydrate also the spatial arrangement of these atoms in every carbohydrate is not similar.

This represents that various carbohydrates contain distinct numbers of carbon, oxygen, and hydrogen atoms that are in different ways in space.

B. Amplitudes in the same direction interference to larger waves

Explanation:

This is because constructive interference is the addition of waves to form a larger wave. In constructive interference, waves with amplitudes moving in the same direction add to form a larger wave.

Answer:

0.25 moles

Explanation:

To find number of moles in 11 g of CO2

44 g of CO2 =1 MOLE

1GM of CO2 = 1/44 mole

11 gm of CO2 = 1/44x11

=11/44 mole

= 0.25 mole

Atoms of two distinct elements are bound together by covalent bonds to form binary covalent compounds. They typically contain nonmetal elements, such as laughing gas NO, a gas that causes acid rain SO₂, etc. Binary covalent compounds are those that consist of just two components.

The definition of a covalent compound is one in which the atoms are joined by a covalent connection. Compounds with just two elements are referred to as binary covalent compounds.

Explanation:

answer: Stoichiometry is a big word for a process that chemist’s use to calculate

amounts in reactions. It makes use of the coefficient ratio set up by balanced

reaction equations to make connections between the reactants and products

in reactions.

 Stoichiometry calculates the quantities of reactants and products in a

chemical reaction. The equation must be balanced!

 Questions that deal with amounts in reactions are examples of reaction

stoichiometry. We already have the tools necessary to solve this question.

We just need to learn a new way to apply skills such as writing chemical

formulas, calculating formula masses, and converting from mass to moles,

particles to moles, and volume of gases to moles.

 Mole to Mole Conversions- you must have the Mole Ratio.

Illustration:

Let’s use an analogy that we can understand to begin to understand the process.

The KEY to any mole conversion is the ratio of coefficients in the reaction

equation. Say I want to make a bacon double cheeseburger. Let’s get our recipe

together.

1 hamburger bun + 2 hamburger patties + 2 slices of cheese + 4 strips of bacon →

1 bacon double cheeseburger

Based on this recipe:

1) If I have five bacon double cheeseburgers:

a. How many hamburger buns did you use? → 5 hamburger bun

b. How many hamburger patties did you use? → 10 hamburger patties

c. How many slices of cheese did you use? → 10 slices of cheese

d. How many strips of bacon did you use? → 20 strips of bacon

2) How many bacon double cheeseburgers can you make if you start with:

a. 2 buns, 4 patties, 4 slices of cheese, 8 strips of bacon

2 bacon double cheese burgers

b. 1 dozen buns, 2 dozen patties, 2 dozen slices of cheese, 4 dozen strips of bacon

1 dozen bacon double cheese burgers

The specific heat of a substance represent the ability of a substance to hold heat. Therefore, the correct option is option B.

The amount of heat needed to raise a substance's temperature by one degree Celsius in one gram, also known as specific heat. Typically, calories as well as joules for every gram per degree Celsius are used as the measures of specific heat.

The notion of specific heat was developed by the Scottish scientist William Black in the 18th century as a result of his discovery that identical quantities of different substances required varying quantities of heat to raise them within a comparable temperature range. The specific heat of a substance represent the ability of a substance to hold heat.

Therefore, the correct option is option B.

Measurement is a way to describe matter with numbers and units.

Measurement is a fundamental process used to describe and quantify various aspects of matter. It involves assigning numerical values to physical quantities and expressing them using appropriate units of measurement.

In scientific and everyday contexts, measurements provide a standardized and consistent way to communicate information about the properties, dimensions, quantities, and characteristics of objects, substances, or phenomena. By using measurements, we can describe the size, length, mass, volume, temperature, time, and many other attributes of matter.

The process of measurement typically involves two components: a numerical value and a unit. The numerical value represents the magnitude or quantity being measured, while the unit provides the reference or scale by which that quantity is expressed. Units help provide meaning, context, and comparability to measurements.

Hence, measurement provides a quantitative and objective way to describe matter, allowing us to understand and interact with the physical world in a systematic and meaningful manner.

Gut bacteria are an important component of the microbiota ecosystem in the human gut, which is colonized by 1014 microbes, ten times more than the human cells. Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function. However, they can also be potentially harmful due to the change of their composition when the gut ecosystem undergoes abnormal changes in the light of the use of antibiotics, illness, stress, aging, bad dietary habits, and lifestyle. Dysbiosis of the gut bacteria communities can cause many chronic diseases, such as inflammatory bowel disease, obesity, cancer, and autism. This review summarizes and discusses the roles and potential mechanisms of gut bacteria in human health and diseases.
