What exercise is most appropriate for testing muscular endurance?
A. Push-up
B. Bench press
C. Back squat
D. Bicep curl
Answer:
Push ups
Explanation:
Muscular endurance is when the muscle have the ability to withstand and sustain contractions that is constantly occur for a long period of time. It include the amount of repeated single exercise that the muscle can endure without resting. It ensures muscular fitness, muscular strength and power.
A good example of muscular exercise is push up the ability to constantly do it for a long time without rest or stopping.
The push-up is the most appropriate exercise for testing muscular endurance. Therefore, the correct option is A.
Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions over a prolonged period of time.
The push-up specifically targets the chest, shoulders, triceps, and core muscles. It requires maintaining a plank position and lowering and raising the body by bending and extending the elbows.
By performing as many push-ups as possible without compromising form, an individual can assess their muscular endurance level.

Compare pure water and coffee. Their pH differs by approximately
Answer:
They differ by two positions in the pH scale.
Explanation:
Hello,
In this case, since coffee has an pH of about 5 which is slightly acidic and water has a pH of 7, their pH differs by 2 approximately:
[tex]\Delta pH=pH_{water}-pH_{coffee}=7-5=2[/tex]
Such acidity in the coffee is caused by the presence of the well-known chlorogenic acid which is besides helpful for us towards reducing the degree of tiredness we eventually acquire along the day.

Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Hello. This question is incomplete. The full question is:
A tRNA anticodon is 5' GAA 3'.
Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Answer:
a) 5' UUC 3'
Explanation:
Anticodons are sequences of nitrogenous bases that establish complementarity with sequences of nitrogenous bases in a codon.
As you know, mRNA has the nitrogenous bases Adenine (A), cytosine (C), guanine (G) and uracil (U). In this system, guanine is supplemented with cytosine and adenine is supplemented with uracil.
These bass are organized into codons, which are a set formed by 3 of these bases.
The tRNA has the same bases, but its codons must recognize and complement the codons of the mRNA, being then called Anticodons.
In this case, if a tRNA has the anticodon 5 'GAA 3', it must bind to codons 5 'UUC 3' in the mRNA.

O Biosphere is a part of the ecosystem
Submit
Request Answer
Answer:
Biosphere is a part of the ecosystem
The correct statement about ecological organization is:
An organism is part of a community.The levels of ecological organization are a hierarchy of categories that go from the micro to the macro (and vice versa), showing us different dimensions of analysis of living beings.
These levels are: organism, population, community, ecosystem, biosphere and biome.
The community is the level made up of a set of organisms of different species, which interact with each other in a specific area.
This includes life forms of all phyla: animals, plants, fungi, bacteria, etc. .
But in turn organisms interact, and these interactions can prevent some very similar species from coexisting (competitive exclusion principle), or the presence of a predator can cause two competitors to remain in low density and therefore there are no exclusion.
Therefore, we can conclude that the organisms of any species (plant or animal) are part of a community and that they coexist in a defined space (the biotope) that offers the external conditions necessary for their survival.

The molecule pictured below produced a blue color when tested with Benedict’s reagent, a yellow color when tested with IKI, and a violet color when tested with Biuret reagent. Based on the structure shown below and these chemical results, what kind of biomolecule is this? the molecule a blue color with benedicts reagent.no color change that given molecule is not a simple carbohydrate
Answer:
The molecule is a protein
Explanation:
When the molecule was tested with benedict's solution and a blue color was formed, that actually meant there was no colour change because the colour of benedict's solution is blue. Benedict's solution is used to test for the presence of reducing sugar, which changes it's colour to green, orange, yellow or even red; the fact that there was no colour change shows the molecule is not a reducing sugar.
Yellow colour when tested with IKI (Iodine-potassium iodide) also shows no colour change. IKI reagent is used to determine the presence of starch, which gives off a dark-blue colour if starch is present. Hence, absence of this dark-blue colour or observation of a yellow/orange colour shows the molecules is not starch.
Biuret reagent is used to test for peptide bonds in a molecule. In the presence of a peptide bond, the biuret reagent changes colour from blue to violet. The amino acids in proteins are held together by peptide bond, hence the biuret colour change shows that the biomolecule is a protein.

When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity?
a) the ions in the solution interact with the sugar and that interferes with its solubility
b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not
c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water
Answer:
c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
Explanation:
A solution contains a solvent (water in this case) and a solute (sucrose in this case). A solution can either be saturated or unsaturated depending on whether it can still dissolve a solute or not.
According to this question, the 0.7 M sucrose solution does not dissolve the sucrose (solute) any longer. This implies that the sucrose solution is getting SATURATED. The saturation of the sucrose solution occurs because the amount of solutes is equating the amount of solvent in the solution.
The solubility of a solution depends upon polarity. The solute molecules (sucrose) adhere to the polar regions of the water molecules (solvent). When this occurs to the point where no other sucrose molecule can adhere, the solution becomes SATURATED so there is no room for more sucrose molecules.

Which statement best compares and contrasts lipids and carbohydrates?
HURRY PLEASEE I HAVE TWO MINUTES JUST THE LETTER AWNSER
The correct answer is B. Both are used for energy storage, but only carbohydrates are used for short-term energy.
Explanation:
Carbohydrates and lipids are both biological macromolecules, which means they are essential for living organisms. Additionally, these are similar because they store energy. However, the type of energy they store is different.
Indeed, carbohydrates store short-term energy, which means carbohydrates are broken down a short time after ingested, and the energy in them is used. On the other hand, in lipids, the energy store is long-term energy, which means it is not consumed as fast as in carbohydrates. This occurs because lipids contain more energy. According to this, the correct statement is "Both are used for energy storage, but only carbohydrates are used for short-term energy".
Answer:
B
Explanation:
Both are used for energy storage, but only carbohydrates are used for short-term energy storage.

Which of these changes to the cell would cause the greatest reduction in the activity of the catalase?
CHOICES:
#1 a return of pH to the normal range
#2 A decrease in the concentration of hydrogen and oxygen
#3 an increase in the concentration of hydrogen peroxide
#4 an increase or decrease in PH beyond normal range
Answer:
#3 an increase in the concentration of hydrogen peroxide.
Explanation:
The changes to the cell that causes the greatest reduction in the activity of the catalase would be - #3 an increase in the concentration of hydrogen peroxide.
Catalase enzyme is present in both plant and animal cells. The catalase is mainly found in aerobic organisms. The substrate for the enzyme is hydrogen peroxide which is broken down into oxygen and water.
The hydrogen peroxide is harmful to the cell and very reactive. Its buildup can kill the cellto breakdown the hydrogen peroxide, the catalase enzyme catalyzes it and convert it into water and oxygenincrease of the hydrogen peroxide leads to a reduction in the activity of the catalase.A single molecule of the catalase can break down 40 million molecules of hydrogen peroxide per minute.Thus, the correct answer is - #3 an increase in the concentration of hydrogen peroxide.
