Answer:
The property of the carbon cycle that makes a good illustration of the conservation of matter is the C) carbon changes form, but the total amount of carbon remains the same.
Explanation:
The law of conservation of matter or conservation of mass states that the mass cannot be created or destroyed, only transformed. It means that the amount of mass is always the same in a closed system. In a chemistry reaction, the mass of reactants must be the same as the mass of the product.
The carbon cycle is composed of different carbon sinks: oceans, the atmosphere, the ground, and the below-ground superficies. Carbon circulates between different sink through chemical, physical, and geological processes that include photosynthesis, respiration, decomposition, and the burning of fossil fuels. Through these processes, carbon travels between sinks; but the sum of the quantity of carbon through all sinks are the same because the carbon cannot be created nor destroyed, only transformed.
Answer:
Aldosterone.
Explanation:
Aldosterone is a hormone that regulates the levels of sodium and potassium in our body, which leads to regulate our fluid levels.
In order to increase the fluids in our system, aldosterone causes the absorption of sodium from our kidneys. The kidneys are the place where our body filters the blood absorbing what it needs, such as sodium, and excreting the rest as urine. With the entering of sodium to our bloodstream, water also enters, increasing the volume of blood in our body.
Aldosterone is also responsible for the excretion of potassium into the urine, controlling the levels of this ion, which is extremely important for a high number of reactions.
B) qRNA
C) rRNA
D) tRNA
Answer:
(A). mRNA.
Explanation:
During protein synthesis, information present in DNA as triplet codons gets transferred to mRNA molecule, by the process of transcription. The mRNA than gets transported to the cytosol, where it associates with ribosomes.
Ribosomes are known as protein factories of the cells as they provide platform for translation. During translation, information present in mRNA is used to translate polypeptide chain or protein as each codon codes for a specific amino acid.
Thus, the correct answer is option (A).
B.deoxyribose
C.phosphate group
D.nitrogenous base
I believe the correct answer is B. Deoxyribose
The nucleotide of a DNA is slightly different to that of RNA due to an addition of a hydroxyl (OH) on the sugar molecule on the RNA nucleotide located on position 2 of the nucleotide.
The DNA and RNA molecules are almost similar.
They both have a nitrogenous base on position one. The nitrogenous base can be one of the 5 bases Adenine, Cytosine, Guanine or Thymine which can be coded by their alternate Uracil in the right places. They are considered to be the building blocks of the DNA and RNA molecules.
Located on position 5 of the nucleotide of both in RNA and DNA is the phosphate group. It has important functions including forming part of an ATP molecule to provide the body with the required energy. They also activate proteins through a process called phosphorilation for example in the cAMP cycle they activate protein kinases.
On the second carbon position there is a ribose sugar. It has only one oxygen molecule linked to each one of the 5 carbon atoms. On the second carbon position, the oxygen molecule is bound to a hydrogen atom forming a hydroxyl (OH). It is only in the RNA that the ribose sugar exists giving it its name; Riboneucleic acid.
The prefix deoxy- means that lack of oxygen. That is where the name deoxyribonucleic acid (DNA) comes from. On the second carbon position of the nucleotide is where there is lack of the oxygen molecule that usually binds to the carbon and hydrogen molecules leaving a hydrogen only bound to the 2nd carbon position. This sugar is only found in the DNA molecule. This small lack of an oxygen bound to the hydrogen allows specific enzymes to be able to identify the difference between a DNA molecule and an RNA molecule.

Difference between the two, DNA and RNA, is that DNA comprises of deoxyribose sugar while RNA comprises of the ribose sugar.
Further Explanation:
DNA and RNA are known to be the most vital molecules in the field of cell biology and is responsible for storing as well as reading the genetic information which basically underpins all life. They are both known to be linear polymers comprising phosphates, sugars, and bases.
DNA or deoxyribonucleic acid and RNA or ribonucleic acid are basically polymers comprises of monomers which are called nucleotides. A molecule of RNA comprises of 5 carbon sugar-phosphate associated with one of the four nucleic acid bases, namely, cytosine, guanine, uracil, and adenine. RNA comprises of a ribose sugar, with the hydroxyl modifications. RNA comprises of only one strand and is also known to be shorter as compared to DNA molecule. As RNA comprises of a ribose sugar, it is known to be more reactive as compared to the molecule of DNA.
In a molecule of DNA, the sugar is lacking the hydroxyl group at the 2’ position and the thymine base is observed instead of uracil. DNA comprises of two strands and it is arranged in a double-helical structure. DNA is considered to be more stable as compared to the RNA molecule due to which, it is useful for the DNA molecule to carry the responsibility for storing the genetic information safely.

T = Q + MC
T = QMC
T = Q divided by the quantity M times C
Answer;
T = Q divided by the quantity M times C
That is; T = Q /(MC)
Explanation;
-Q or heat flow, or thermal energy is measured using temperature change and calculated using the formula Q= MC Δt., Where M is the mass, c is the specific heat capacity and delta t is the change in temperature.
-From the formula; To determine the change in temperature, we just divide the given formula by the product m×c, both sides,
ΔT = Q/mc
-To determine the specific heat capacity we divide both sides by the product m×delta T
c = Q/m×Delta T
To determine the mass, we divide both sides by the product c×delta T.
m = Q/c×Delta T
Answer : The correct option is, T = Q divided by the quantity M times C
Explanation :
The given formula is,
where,
Q = heat released or absorbed
M = mass of a substance
C = specific heat of a substance
T = change of temperature
To write the given equation in the form of T only, we rearrange the equation and we get :
Hence, the correct option is, T = Q divided by the quantity M times C
