A sample of DNA contains 120 nucleotides, if 35 nucleotides are Guanine, how many nucleotides are Thymine?
(If you can show how you do it that would be great)
Answer:
25
Explanation:
In DNA, Guanine pairs with Cytosine, and Thymine pairs with Adenine. This tells us that there are equal numbers for each Guanine and Cytosine, and Thymine and Adenine. When there's 35 Guanine, there should be 35 Cytosine that goes with it. 120 - 2(35) = 50. The remaining 50 nucleotides are Thymine and Adenine, and since they are the same number, divide 50 by 2. 50 ÷ 2 = 25. There are 25 thymine in the sample of DNA.
Which term describes the idea that Earth’s landforms change at a constant, steady rate?
The ________ helps keep food between the grinding surfaces of the teeth during chewing.
The ______ carries urine from the kidney to the bladder, and the ______ carries urine from the bladder to the outside of the body.
The Ureter Carries urine from the kidney to the bladder, and the Urethra carries the urine to the outside
The urinary systemThe ureter carries urine from the kidney as a waste product obtained from the consumption of food and liquid substance to the bladder, which acts as a temporary storage of urine. When the bladder storage is saturated the urine is released to the outside of the body through the urethra.
Hence we can conclude that The Ureter Carries urine from the kidney to the bladder, and the Urethra takes the urine outside the body.

A chemical change occurs when both the physical properties of a substance and its identity change. The correct option is C.
What are chemical changes?A chemical change is a change when the identity of a substance changes, and it converts into a new substance with new characteristics and a new identity.
When iron comes in contact with oxygen, it changes into rust, and it is a chemical change. A chemical change is a transformation in which the substance's chemical composition is altered through atom rearrangement. Atomic alterations cause changes in the molecular structure.
Chemical properties are those property properties of a substance that does not depend on the quantity of that substance.

How does adding carbon dioxide to the ocean
affect its pH?
Provide an explanation for the results (or what should have happened) using SCIENTIFIC REASONING
Explanation:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
All species have a maximum tolerance limit before they are no longer suited to live in their environment. In three to five sentences, discuss the potential outcomes for a species when that maximum limit is reached. There are at least four possibilities, and one point will be assigned per potential outcome mentioned.
The potential outcome of maximum tolerance limit is reduction of population.
What is the outcome of maximum tolerance limit?The potential outcomes for our species happens when maximum tolerance limit is reached. Due to this, the population of that organism can decrease. As many species can die due to maximum tolerance limit, it can cause a reduction in reproductive rate as well as reduce life span off individuals.

The structures of five of the compounds of glycolysis are given. Arrange the compounds in order from the start of glycolysis to the end of glycolysis
Through the glycolysis process, the glucose molecule turns into pyruvate. The correct order of structures is Glucose/Fructose-1,6-biphosphate/Glyceraldehyde 3-phosphate/1,3-diphosphate glycerate/Pyruvate.
What is glycolisis?Glycolysis is the process through which the cell partially decomposes glucose and turns it into pyruvate.
It is about a series of enzymatic reactions that take place in the cytosol and do need no oxygen to occur. So it occurs in aerobic and anaerobic respiration.
It can be divided into two phases:
1st phase produces two 3-C molecules. This step needs the energy of two ATP molecules.2nd phase produces pyruvate, two ATP, and one NADH from each 3-C molecule.To sum up, glycolysis transforms one glucose molecule (6-C) into two pyruvate molecules (3-C), four ATP, and two NADH. Since it also consumes two ATP molecules, the net product is two ATP.
Steps
1) Glucose phosphorylation by hexokinase. A phosphate group is driven from ATP to glucose, turning it into glucose-6-phosphate -G6P-
Glucose + ATP ⇔ Glucose-6-phosphate + ADP
2) Glucose-6-phosphate isomerization. The enzyme glucose-6-phosphate isomerase turns glucose-6-phosphate into fructose-6-phosphate
Glucose-6-phosphate ⇔ fructose-6-phosphate
3) Fructose-6-phosphate turns into Fructose-1,6-biphosphate. The enzyme phosphofructokinase-1 phosphorylates Fructose-6-phosphate, providing a phosphate group from ATP to the Fructose-6-phosphate molecule.
Fructose-6-phosphate + ATP ⇒ Fructose-1,6-biphosphate + ADP
4) Aldolase enzyme divides Fructose-1,6-biphosphate into phosphate dihydroxyacetone (3-C molecule) and 3-phosphate glyceraldehyde (3-C molecule).
Fructose-1,6-biphosphate ⇔ phosphate dihydroxiacetone + 3-phosphate glyceraldehide
5) Phosphate dihydroxyacetone Isomerization into glyceraldehyde 3 phosphate -G3P- by triose phosphate isomerase.
phosphate dihydroxyacetone ⇒ glyceraldehyde 3 phosphate
6) Glyceraldehyde 3-phosphate oxydation by G-3-P dehydrogenase (GAPDH or GAP). The enzyme adds a phosphate into C-1 of the molecule, turning it into 1,3-diphosphate glycerate. To do it, the enzyme reduces an NAD+ group and turns it into NADH and an H ion.
gliceraldehide 3 phosphate + NAD⁺ + P ⇒ 1,3-diphospho glycerate + NADPH + H⁺
7) 1,3-diphosphate glycerate loses a phosphate group and turns into 3-phosphoglycerate.
1,3-diphospho glycerate + ADP ⇒ 3-phosphoglycerate + ATP
8) 3-phosphoglycerate isomerization, turning it into 2-phosphoglycerate by phosphoglycerate mutase.
3-phosphoglycerate ⇒ 2-phosphoglycerate
9) Phosphoenolpyruvate production. A double bond is formed at carbon 2 where the phosphate group was attached. A water molecule is released (hydrogen of carbon 2 and the OH- group of carbon 3) from the 2-phosphoglycerate.
2-phosphoglycerate ⇒ Phosphoenolpyruvate + H₂O
10) Pyruvate dephosphorylation and ATP formation by pyruvate kinase.
Phosphoenolpyruvate + ADP ⇒ Pyruvate + ATP

The correct order of the structures from the start of glycolysis to the end of glycolysis is Glucose → Fructose-1,6-biphosphate → Glyceraldehyde 3-phosphate → 1,3-diphosphate glycerate → Pyruvate.
What do you mean by Glycolysis?Glycolysis may be defined as a process in which one molecule of glucose is partially oxidized into the two molecules of pyruvate in a series of 10 enzyme-catalyzed reactions.
The first phase of glycolysis converts a 6-carbon molecule to two 3-carbon molecules with the help of ATP. The second phase is the payoff phase where a 3-carbon molecule may transform into the same carbon molecule known as Pyruvate with the release of energy.
Therefore, it is well described above.
