Question 14
Anita was using steel to make rusted sculptures. After building each sculpture, she caused the steel in the sculpture to rust by placing it into a tub filled
with salt water for eight hours. Anita wondered if steel would rust faster submerged in vinegar instead of salt water. To find out, Anita cut ten squares of
steel sheet metal and split them into two equal groups. She put one group of squares into a tub filled with salt water and the other group of squares
into a tub filled with vinegar. Once an hour for eight hours, Anita counted the number of rusted steel squares in each group.
What is the manipulated/independent variable in Anita's experiment?
A
number of rusted squares
B
time left in the liquid
ООО
С
the number of metal squares
D
the type of liquid the squares were placed in

Answer: D. the type of liquid the squares were placed in
Explanation:
An independent variable is required to be changed in an experiment which can observe the changes in the dependent variable, which is the outcome of the experiment.
The type of liquid used to rust the steel squares is the independent variable of the experiment and dependent variable is the rust on steel.

Explanation:
Both strands of the DNA double helix contain nitrogenous bases held together by hydrogen bonds. In DNA, the sequence of nitrogenous bases varies widely. What is the significance of the nitrogenous bases? (6A) Question 4 options: They determine the amino acids in the proteins synthesized. They prevent mutations from occurring in the process of DNA replication They help complete the sugar-phosphate backbone of DNA molecules. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.
Answer: They determine the amino acids
Explanation: The sequencing of the bases directly code for the amino acids. If anything changes, it would change the code, and could possibly create a different gene all together.
The significance of the nitrogenous bases is that they determine the amino acids in the proteins synthesized.
DNA:
Deoxyribonucleic acid is a biological molecule that stores genetic information in living cells. DNA is a polymer made up of monomers called nucleotides. In the nucleotide subunits of DNA, nitrogenous bases are one of the components. The sequence of nitrogenous bases in DNA molecules varies from one another. This is because the sequence determines the sequence of amino acid that will form proteins when translated. Therefore, the significance of the nitrogenous bases is that they determine the amino acids in the proteins synthesized.Learn more at: https://brainly.com/question/22499464?referrer=searchResults

2. Why did the scientists find Henrietta’s cells so important? (What was different about Henrietta’s cells than other cells scientists had used?)
Answer:
Henrietta's cells never died/they kept replicating/they are immortal cells
Explanation:
Cells typically die after so many replication cycles, her cells did not. They are considered immortal cells. They have an over active telomerase that rebuilds the telomeres after each division. Therefore these cells do not age and can continue replicating
A researcher performed an experiment in which he exposed young corn plants to a harmless, radioactive form of carbon dioxide gas containing carbon-14 instead of carbon-12. He then began feeding corn produced by the plants to a small group of goats. After several weeks, the researchers took blood and tissue samples from the goats. He was able to detect increased concentrations of carbon-14 in the goats' lipids, proteins, carbohydrates, and DNA
Answer:
See the answer below
Explanation:
A researcher performed an experiment in which he exposed young corn plants to a harmless, radioactive form of carbon dioxide gas containing carbon-14 instead of carbon-12. he then began feeding corn produced by the plants to a small group of goats. after several weeks, the researcher took blood and tissue samples from the goats. he was able to detect increased concentrations of carbon-14 in the goats' lipids, proteins, carbohydrates, and dna. which statement best explains the researcher's findings?
a. uptake of radioactive carbon dioxide gas caused carbon atoms to be found in places they wouldn't normally be found.
b. carbon atoms found in the sugar molecules of the corn were used by the goats' bodies to form other large molecules.
c. like the corn plants, the goats experienced prolonged exposure to carbon dioxide gas containing carbon-14.
d. eating corn containing radioactive carbon-14 caused many of the goats' other carbon atoms to become radioactive.
The correct answer here would be that the carbon atoms found in the sugar molecules of the corn were used by the goats' bodies to form other large molecules.
This is usually what happens when organisms feed on nutrient-containing substances. The nutrients are extracted during digestion and are utilized in the anabolic processing of important biomolecules in the body of the organism.
Carbon is an important element in all biomolecules of life such as lipids, proteins, nucleic acids, etc. and as such, the carbon present in the corn consumed by the goats must have been used to form some of these molecules in the bodies of the goats.
The correct option is b.

Energy transfers from the milk. What is your reasoning?
Energy transfers to the milk.
Energy transfers to the coffee.
None of the above
Students, draw anywhere on this slide!
Answer:
Energy transfers from the milk
Explanation:
The kinetic energy of the particles in cold milk is low. They are all moving slowly. When you pour cold milk into hot coffee, the milk and coffee particles start to collide When a high-energy coffee particle hits a low-energy milk particle, energy transfers. The coffee particles slow down, and the cup of coffee cools down.
Use the words haploid cell, diploid cell, and fertilization all together in a sentence.
Answer:
The sexual life cycles involve the alternation between meiosis and fertilization. Meiosis is a process where the diploid cells gives a rise to haploid cells, and fertilization is the process where two haploid cells (gametes) fuse to form a diploid zygote.
Explanation:
Hope this helps
Using the words haploid cell, diploid cell, and fertilization all together in a sentence - Fertilization is the union of two unicellular, haploid gametes to produce one unicellular, diploid zygote.
The process of combining the male gamete, or sperm, with the female gamete, or ovum. The product of fertilization is a cell called a zygote.
Fertilization takes place when two haploid cells fuse together such as sperm cells and egg cells.Haploid cells have a single set of chromosomes.The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes that fuse during fertilization.Diploid cells are a cell that contains two sets of chromosomes that are formed after fertilization also called a zygote.Thus, the correct sentence would be - Fertilization is the union of two unicellular, haploid gametes to produce one unicellular, diploid zygote.

1. In the system shown below, there are 80 x particles, all in region A (the left half of the box). No extra particles can enter the system. When the system is in
equilibrium, what will be true of the particles?
A Since there are no y particles, the system is already in equilibrium with ail 80 x particles in A
B. Due to the constant motion of particles, this system will never reach equilibrium
C. In equilibrium, there will be exactly 40 x particles in A and 40 x particles in B, and those numbers will remain constant
Din equilibrium, there will be approximately 40 x particles in A and 40 x particles in B, and those numbers will fluctuate but will remain near 40
Answer:
The correct answer is - option D. in equilibrium, there will be approximately 40 x particles in A and 40 x particles in B, and those numbers will fluctuate but will remain near 40.
Explanation:
Equilibrium is the condition where all the condition is where all the factors or influence forces are balanced in a particular system. The perfect balanced condition is not easy to get or can not remain constant for long.
In this example, both A and B get 40 x particles to be in equilibrium however fluctuation persists but still approx 40 remains.
Thus, the correct answer is - option D
How is ADP converted to ATP?
by the addition of one adenosine molecule
Answer:
Two processes convert ADP into ATP: 1) substrate-level phosphorylation; and 2) chemiosmosis. Substrate-level phosphorylation occurs in the cytoplasm when an enzyme attaches a third phosphate to the ADP (both ADP and the phosphates are the substrates on which the enzyme acts).
