Describe the effects of anaerobic respiration on the body and explain the effects on the body
Answer:
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.

Answer:
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.
Explanation: Living things need energy for everything they do, including growing and reproducing. This energy comes from glucose. All animals and humans get glucose through eating it, but plants need to make their own glucose during photosynthesis.
Plants and animals transport glucose and oxygen to tiny structures in their cells, called mitochondria. Here, the glucose and oxygen take part in a chemical reaction. The reaction is called aerobic respiration, and it produces energy which transfers to the cells.
Aerobic respiration makes two waste products:carbon dioxide and water. Animals remove carbon dioxide from their bodies when they breathe out. In daytime, plants use some of this carbon dioxide for photosynthesis. At night, they release the carbon dioxide to their surroundings.
PLESE HELP! Which of the following sugar solutions is the most concentrated?
Select one:
a. 25 g of sugar in 60 mL of water
b. 2 g of sugar in 100 mL of water
c. 15 g of sugar in 25 mL of water
d. 12 g of sugar in 30 mL of water
c.15gof in25mlof wather
The sugar solution that is the most concentrated is 15 g of sugar in 25 mL of water.
CONCENTRATION:
The concentration of a solution is related to the amount of a substance and its volume. The concentration of a solution is directly proportional to the amount of a substance but inversely proportional to the volume. This means that the concentration increases with an increasing amount of substance but decreases with an increasing volume. According to this question, 15g of sugar is the highest amount and it dissolves in 25mL of water, which is the lowest volume. Therefore, it is the most concentrated sugar solution.Learn more at: https://brainly.com/question/202460?referrer=searchResults

What are the two types of microscopes?
+
Answer:
1) The light microscope. The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object. The lens closest to the eye is called the ocular, while the lens closest to the object is called the objective. Most microscopes have on their base an apparatus called a condenser, which condenses light rays to a strong beam.
2) Other light microscopes. In addition to the familiar compound microscope, microbiologists use other types of microscopes for specific purposes. These microscopes permit viewing of objects not otherwise seen with the light microscope.
3) The fluorescent microscope uses ultraviolet light as its light source. When ultraviolet light hits an object, it excites the electrons of the object, and they give off light in various shades of color. Since ultraviolet light is used, the resolution of the object increases. A laboratory technique called the fluorescent‐antibody technique employs fluorescent dyes and antibodies to help identify unknown bacteria.

magine that you need to take a medicine that the doctor has prescribed for you. Explain why scientists who developed that medicine would need to know whether or not the compound in that medicine is polar. How might a polar medicine behave differently as it dissolved in the body than a nonpolar medicine would?
Answer:
hi
Explanation:
The compound in medicines should be non polar. Therefore scientists need to be sure of using compounds that are non polar in nature so they pass through the cell membrane and enter into the blood circulation of the body and perform its due function.

How many times as bright as a light that is 90 m away from you does a light that is 10 m away from you appear?
Answer:
81 x as bright
Explanation:
The intensity of light is dependent on distance according to this simple equation:
(90/10)^2 = 9^2
= 81
This was derived from the inverse-square law. Respectively a light that is 10 m away from you is 81 x as bright.

What is an ideal gas equation?
The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
Using the ideal gas equation
PV =nRT
Where P is the pressure
V is the volume
n is the number of moles
R is the ideal gas constant (R = 0.08206 L atm mol⁻¹ K⁻¹)
T is the temperature.
From the given information
V =?
n = 7.59
and at STP
P = 1 atm
T = 273 K
Putting the parameters into the formula, we get
PV =nRT
1 atm x V = 7.59 mol x 0.08206 L atm mol⁻¹ K⁻¹ x 273 K
V = 170.034 L
Hence, 170.034 L is the volume of a container containing 7.59 moles of krypton gas at STP.

Answer:
it may be +1 or -1 hope this help
An atom is a kind of stuff that cannot be further decomposed chemically. Therefore, the charge on a single proton is +1.
What is atom?
The building block of an element is an atom. An atom is a kind of stuff that cannot be further decomposed chemically. The three main components of an atom are protons, neutrons, plus electrons.
Some substances are either bigger or smaller than atoms. Instances of chemical species that aren't commonly regarded as atoms include protons, neutrons, and electrons, which are atom-related particles. Atoms make up molecules and compounds, however they are not actual atoms. Salt is an example of a molecule and a compound (NaCl). The charge on a single proton is +1.
Therefore, the charge on a single proton is +1.

35. 124.31 g of silver nitrate reacts with 52.89 g of sodium chloride.
g
a. What is the mass of the products?
Answer: Thus mass of products is 177.2 g
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction is:
[tex]AgNO_3+NaCl\rightarrow NaNO_3+AgCl[/tex]
mass of silver nitrate [tex](AgNO_3)[/tex] = 124.31 g
mass of sodium chloride [tex](NaCl)[/tex] = 52.89 g
mass of reactants = mass of silver nitrate [tex](AgNO_3)[/tex] +
mass of sodium chloride [tex](NaCl)[/tex] = 124.31 g + 52.89 g = 177.2 g
Thus mass of products = mass of reactants = 177.2 g
