A student did an experiment with two identical fish tanks, Tank 1 and Tank 2. About 20 ml water purifier was added to Tank 1 and 10 ml
water punfier was added to tank 2. Tank 1 was heated to 88° F and Tank 2 was left at room temperature. The water purity of each tank was
tested every day in particles per liter. The purity was recorded over a period of 5 weeks in the table shown below.

d

Water purifier keeps fish tanks clearer for longer.

pleasee helppp !!​

Answers

Answer 1

Answer:

a . Fish need 10 ml of water purifier to survive.

Explanation:

Fish need 10 ml of water purifier to survive because the data of 10 ml and 20 ml purifier is the same so it is recommended to use 10 ml purifier. First the data was same but by recording next week data, it shows slightly increase in the value of tank 2 while in the last week, both has the same value so we can concluded that by using 10 ml purifier is enough for the fish to survive.

Answer 2

Answer:

Its B/More purifier is needed to keep heated water clean.

The cell membrane is also referred to as the plasma membrane or cytoplasmic membrane of the cell. It lays various functions in the cell.

The correct answer is:

Option B. controls what enters and leaves the cell

Role of the cell membrane are:

The cell membrane is a biological membrane, which separates the interior of the cell from the external environment.

The cell membrane is selectively permeable such that it allows certain molecules to pass through them.

The cell membrane controls the entry and exiting of molecules from the cell.

Which enzyme is used in gluconeogenesis, but NOT in glycolysis? Group of answer choices PEP carboxykinase enolase (interconverts 2-phosphoglycerate and phosphoenolpyruvate)

PEP carboxykinase

Explanation:

PEP carboxykinase is also known as Phosphoenolpyruvate carboxykinase. It is an enzyme which is used for the production of glucose from non-carbohydrate carbon substrates. This enzyme is used only in gluconeogenesis not in glycolysis because this enzyme helps in the production of glucose while glycolysis is a process in which the glucose  break down into pyruvate and ATP molecules.

DNA is transcribed to messenger RNA (mRNA), and the mRNA is translated to proteins on the ribosomes. A sequence of three nucleotides on an mRNA molecule is called a codon. As you can see in the table, most codons specify a particular amino acid to be added to the growing protein chain. In addition, one codon (shown in blue) codes for the amino acid methionine and functions as a "start" signal. Three codons (shown in red) do not code for amino acids, but instead function as "stop" signals.
Sort the following ten codons into one of the three bins, according to whether they code for a start codon, an in-sequence amino acid, or a stop codon
AUG, UAG, UAA, UGA, AAA, UGC, AUC, CAC, GCA, ACU

Answers

Answer:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

Explanation:

From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.

Hence, using the attached amino acid chart:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

In most organisms, the end product of glycolysis is pyruvate. Pyruvate still contains a substantial amount of energy, which can be further extracted. Whether the organisms are operating under aerobic or anaerobic conditions determines the metabolic pathway that pyruvate undergoes to produce more ATP. In this tutorial, you will identify the end products of these metabolic pathways.

Answers

Answer:

Pyruvate helps in the production of ATP.

Explanation:

The molecule of pyruvate converted into acetyl CoA. Then each molecule which is produced during glycolysis loses electron and carbondioxide releases. After the breakdown of pyruvate, the electrons loses by pyruvate are transferred to NAD+ in order to produce NADH, which will be used by the cell to produce energy molecule such as ATP. So we can say that pyruvate plays a vital role in the formation of ATP molecule.

When protein is hydrolyzed, it forms amino acids. Thus, the correct option is A.

What is Hydrolysis?

Hydrolysis may be defined as a chemical process that utilizes the molecules of water that involve the chemical breakdown of a compound.

Amino acids are the monomers of protein. These amino acids are linked together by peptide bonds. But the process of hydrolysis breaks the peptide bond between the amino acid sequences and released them significantly in free form.

Therefore, when protein is hydrolyzed, it forms amino acids. Thus, the correct option is A.

When an enzymatic reaction is in progress, do you expect to see an increase, decrease or no change in each of following: (i) substrate (ii) product (iii) enzyme

Answers

Answer:

During Enzymatic reaction, enzymes binds to a substrate to form a which then forms the product.

Substrate: A reactant in an enzymatic or chemical reaction is called substrate. Product: The final outcome or substance after completion of reaction is called product.Enzyme: Enzyme helps to increase the rate of reaction and act as a catalyst.

Change in shape of substrate, product and enzymes depends on the temperature outside the optimal range which affect bonding between enzyme and substrate. Enzymes definitely changes their size when bind to substrat and the process is called induced fit which increases the rate of reaction.

During an enzymatic reaction, their is an decrease in the concentration of substrate, an increase in the concentration of product, and no change in the concentration of the enzyme.

What is enzymatic reaction?

A reaction, which is mediated with the help of an enzyme is termed as enzymatic reaction. A substance, which functions as a catalyst in living organisms and regulate the rate at which the chemical reactions takes place is known as an enzyme.

The enzymatic reactions follows the lock and key model, in which the free enzyme combines with the substrate and forms the enzyme-substrate complex, this is further catalyzed into the enzyme-product complex, from which the free enzyme and product get discharged. The product never further binds with the free enzyme.

In the reaction, the substrate get used up thus its concentration decreases, while the formation of product takes place thus its concentration increases. However, there is no change in the concentration of the enzyme as it does not get used up in the process.

Thus, in enzymatic reaction, substrate decreases, product increases, and enzyme concentration remains the same.
