Answer:
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.

What is the wavelength of the electromagnetic radiation emitted?
Answer:
410 nm
Explanation:
when an electron falls from ni=6 to nf=2 , a photon of wavelength 410 nm is emitted.
When an electron falls then the wavelength of the electromagnetic radiation emitted is = 410 nm.
What is electromagnetic wavelength?
When The Electromagnetic wavelength directs to the measured distance between the trough or crest of each adjacent wave generated by the electromagnetic disturbance.
When the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).
Now we are Showing that the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).
Therefore, when an electron falls from ni=6 to nf=2, a photon of wavelength 410 nm is emitted.

How many particles are present in a 56.9 mole sample of calcium hydroxide?
Answer:
Particles? Calcium hydroxide does not exist as discrete molecules, but as a network solid. The only way you would have separate particles, is if the calcium hydroxide was dissolved in a boatload of water. Ca(OH)2 is not all that soluble in water. Nonetheless, assume a lot of water, enough to dissolve 56.9 moles.
Ca(OH)2 --> Ca2+ + 2OH-
56.9 moles Ca(OH)3 x (3 moles ions / 1 mol Ca(OH)2) = 170.7 mol ions
==================
Percent composition of CuNO3......molar mass = 125.5 g/mol

Which element is a noble gas? pls help!!
Answer:
HE (helium)
Explanation:
Answer: Helium
Explanation: If you look at a periodic table noble gasses are on the far right side
Most representative metal atoms tend to gain enough electrons to attain a stable noble gas (octet) configuration.
True or False
Answer:
False
Explanation:
Non- metals tend to gain electrons easily, metals tend to lose electrons easily
For example, oxygen, a non-gas, when it is an ion, has the option to lose 6 electrons to become like helium, or gain 2 electrons to become like the noble gas neon. However, it becomes like neon for 2 reasons.
A. As a general rule, atoms lose/gain the LEAST amount of electrons.
B. Oxygen is a nonmetal, therefore, to become like a Noble Gas, it would gain, as non-metals usually would, 2 electrons.
What is the freezing point of solution that has 185.25 grams of Ca(OH)2 (formula mass = 74.1) dissolved in 2,500 grams of water at standard pressure?
Answer:
The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.

If two vectors combine in the same direction what mathematical operation would you use to
find the resultant vector?
Answer:
The head-to-tail rule is used to sum two vectors pointing in the same direction. (Vectors in the same direction are called collinear). The sum vector is slightly moved out of its correct position so that you can see it. For now, to determine if two vectors have the same direction look at a picture or use geometry.

The period of time needed for a radioisotope to lose one-half of its activity is known as that isotopes
Explanation:
The radioactive scattering technique is called radioactive degradation. For each radioactive isotope, the natural radioactive cycle is special and is determined by a period of time termed a half-life. One half-life was its time needed to experience radioactivity for half of both the radioactive nuclei.

Which of the elements shown has an atomic mass of 20 amu?
A) A
B) B
C) C
D) D
The elements shown have an atomic mass of 20 amu is Neon.
What is atomic mass?
The atomic number of an atom is its total number of protons and neutrons.
Neon has an atomic mass of about 20 this isotope contains 10 protons and 10 neutrons.
Actually, Neon would be listed as having an atomic mass of about 20.18 because of a mixture of isotopes.
Z= Atomic number the number of protons in the nucleus which defines the element.
In this case, Z=10 and this means neon but there are also 10 neurons in the nucleus of the major isotope which gives it 20Ne.
Hence, option D is the correct answer.

Chemical bonds form because: a. The atoms have more energy bonded together than separated b. The atoms have less energy bonded together than separated
Answer:
A. The atoms have more energy together than separated.
Explanation:
There are several reasons why a chemical bond could take place. Adding things like heat or pressure stimulate the atoms to force a reaction to take place. But when it comes down to it, the intramolecular forces of the electrons pull each other to form chemical bonds (represented by Valence electrons). The stronger these are, the more likely they are going to bond.
Atoms with lower forces typically don't typically bond with other atoms of lower forces.

One energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.
What is energy transformation?Energy transformation is the process in which one form of energy converted into another form of energy.
What is photosynthesis process?Photosynthesis process is defined as the process in which plants makes their own food by using the carbon dioxide, water and sunlight in the chlorophyll.
The balanced chemical equation of photosynthesis process is
6CO2 + 6H2O → C6H12O6 + 6O2.
Since, it have 6 atoms of carbon, 12 atoms of hydrogen and 18 atoms of oxygen on both side. So, it is balanced.
Since, sunlight which it take is in the form of radiant and convert it into chemical energy.
Thus, we concluded that the energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.
