Answer: mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH
Explanation:
Two pyruvate molecules remain at the end of glycolysis which still have a lot of extractable energy. The next step in storing the remaining energy in the form of ATP is oxidation by pyruvate. The transition steps are as following:
Pyruvate must join the mitochondrion, cross its inner membrane and arrive at the matrix before the chemical reactions can begin. A group of carboxyl (one carbon molecule) is snipped off of pyruvate and released as a carbon dioxide molecule, leaving behind a two-carbon molecule called the acetyl group. The oxidised two-carbon molecule, acetyl group attached to Coenzyme A to form acetyl CoA.The additional energy during conversion is reduced NADH molecules and two carbon dioxide molecule.Hence the correct order to fill the blanks is mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH.

Which of the following best defines metabolism?
Choose 1 answer:
A.) Any process that requires energy
B.) A reaction that breaks down large substances into smaller ones
C.) The process of building complex molecules from simple molecules
D.) The complete set of reactions carried out by a cell
Answer:
The answer is B.
Explanation:
Metabolism is the process where large molecules are broken down into smaller molecules to obtain energy.
The statement 'the complete set of reactions carried out by a cell' BEST defines metabolism (Option D).
Metabolism refers to all chemical reactions that cells perform to carry out their functions (e.g., growth, differentiation, reproduction, etc).
Metabolic reactions can be divided into anabolic reactions and catabolic reactions.
Catabolic reactions are metabolic reactions that break down large molecules into smaller molecules, thereby releasing energy.
Anabolic reactions are metabolic reactions that synthesize large molecules by using smaller molecules, thereby consuming energy.
In conclusion, the statement 'the complete set of reactions carried out by a cell' BEST defines metabolism (Option D).

If the DNA nucleotides read 3'-ATG-CGT-GAC-5', the amino acid sequence of the resulting polypeptide
(protein) would be what?
Answer:
5’ – TAC-GCA-CTG-3’
Explanation:
As per the Chargaff’s complementary base pairing rule purine always pairs with a pyrimidine.
Purines include adenine (A) and cytosine (C)
Pyrimidine include thymine (T) and guanine (G)
Thus an A always pair with T and C always pair with G
Thus, the resulting poly peptide for the given amino acid sequence is

2. When you decrease the pH in the simulation, the ocean's acidity increases. What do you expect
to happen over time to the population of the corals, algae, and fish in the coral reef as the pH of
the ocean decreases?
Answer:
With decrease in pH of ocean water, the survival rate of corals, algae, and fish in coral reef reduces.
Explanation:
Coral reefs find difficulty in living in acidic ocean water. It is so because the coral’s shell that is made up of calcium carbonate is unable to sustain in acidic environment.
Not only this the skeleton of snails, clams, algae , fish etc is also made up of calcium carbonate. Increased acidity leads to death of these species.
Thus, the lower is the pH of ocean water, the higher is its acidity and hence the lower is the probability of survival of corals, algae, and fish in the coral reef
pH is among the limiting factors that might affect coral, algae and other species. A decrease in water pH causes an increase in acidity, which leads coral, algae, and fish in the coral reef to death.
What is the relationship between corals and algae?
Corals are translucid or white, but they look brightly colored because they host symbionts with colorful photosynthetic pigments . They can host different organisms that live on and among them, giving place to an amazing ecosystem.
One of these organisms is the photosynthetic unicellular microalgae, called zooxanteles. Corals provide shelter and protection to the algae, while algae provide nitrogenated nutrients, sugars, and color to the corals.
This symbiotic relationship allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as the tropical clear waters.
What are the limiting factors of corals and algae?Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.
Some of these factors are water, temperature, pH, salinity, and radiation.
When changes in any of these factors occur, corals react to these changes losing these algae and becoming translucid again.
pH is a significant limiting factor for coral survival because their calcium-carbonated shell is sensitive to acidic environments.
When there is a decrease in oceanic pH, occurs an increase in water acidity, causing coral, algae, and other organisms death.

What is the acceleration of a 50 kg object pushed with a force of 500 newtons
Force is equal to mass times acceleration, therefore acc. is equal to Force divided by mass.
500 N /50kg equals 10m/s^2.
The acceleration of a 50 kg object pushed with a force of 500 Newtons is 10 m/s^2, calculated using Newton's second law of motion.
Explanation:To calculate the acceleration of an object, we use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration (F = ma). If a 50 kg object is being pushed with a force of 500 Newtons, you would solve the equation for acceleration, a = F/m. Thus, a = 500N / 50kg = 10 m/s^2.

Moreover, growth rates are computed by dividing the difference between the ending and starting values for the period being analyzed and dividing that by the starting value.
Therefore, the growth rate of a value (GDP, turnover, wages, etc.) measures its change from one period to another (month, quarter, year). It is very generally expressed as a percentage.

d. Phospholipids
Answer:
A
Explanation:
There was no picture but the cell membrane does surround the cell and it is a phospholipid bilayer made of triglycerides so it is answer choice A
Phospholipids disposed in a lipidic bilayer compose the cell membrane. Their hydrophilic heads are facing the exterior, and hydrophobic tails facing the interior. The answer is d. Phospholipids.
MEMBRANE COMPOSITION
The cell membrane is composed of two lipidic bilayers, cholesterol, proteins, and glucans incrusted in between.
⇒ LipidsPhospholipids are amphipathic molecules.They have hydrophilic heads facing the exterior and the interior of the cells and hydrophobic tails that arrange against each other in the interlayer space.Lipids can easily change places with other lipids by lateral diffusion in the same layer.They can diffuse transversally to the other layer but not as easily as lateral diffusion.There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.⇒ CholesterolThese molecules are incrusted in the membrane between the hydrophobic tails of lipids.
⇒ ProteinsAmong the proteins, we can find integral proteins and peripheric proteins.
