In general, the land changes temperature much more rapidly than the
ocean. How does this fact explain the existence of land breezes and sea breezes?

Answers

Answer:

Answer

Explanation:

Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean.

The lac operon is regulated by both the availability of lactose and glucose. How does E. coli regulate transcription of the lac operon?

Answers

Answer:

E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).

Explanation:

The lac operon is regulated by both the availability of lactose and glucose. E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).

This cAMP acts a signaling agent which is made by E. coli anytime glucose levels are low In the cells which helps regulate the transcription process as glucose is needed for it .

When crude oil is distilled, it is separated into categories. What are those categories characterized by?

Answers

Answer:

Differences in their boiling points

Explanation:

When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.

At different boiling points, each of the fraction will separate out.

Crude oil is made up of different fractions of hydrocarbons. As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases. Components with short carbon lengths rises out from the column first and are cooled and extracted. The categories are thereby, classified based on differences in their boiling points.

Given the sequence of DNA bases sequence:

Transcription into mRNA and translation would be:

mRNA          AUG CUC AAC GGC AUA UAACGC GAG CUG ACG Amino acids Met (Start)-Leu-Asn-Gly-Ile-Stop-Arg-Glu-Leu-Thr

Explanation:

Genetic information is found in DNA, and this information depends on a sequence of bases —adenine, thymine, cytosine and guanine— in the DNA molecule.

Transcription consists of creating a strand of mRNA, from the sequence of bases in a DNA strand, which it assumes:

The sequence of RNA is complementary to the DNA sequence that forms it, following the complementarity of bases. In RNA there is no base thymine, which is replaced by uracil.

The sequence of mRNA is organized into triplets or codons, each of which encodes for the synthesis of an amino acid (translation), indicating both the start of a polypeptide chain and the stop of protein synthesis.  Knowing this information, it can be stated that, following a sequence of DNA bases, the resulting transcription and translation would be:

DNA                TAC GAG TTG CCG TAT ATT GCG CTC GAC TGC Transcription AUG CUC AAC GGC AUA UAACGC GAG CUG ACG Translation    Met (Start)-Leu-Asn-Gly-Ile-Stop-Arg-Glu-Leu-Thr

Resulting amino acids and indications in protein synthesis Methionine (inicio), Leucine, Asparagine, Glycine, Isoleucine —Stop— Arginine, Glutamine, Leucine and Tyrosine.

A certain wastewater treatment plant uses aerobic bacteria, anaerobic bacteria and archaebacteria during secondary treatment of sewage. Unfortunately, during a bad bluzard the sludge digester froze, killing the microbes inside. What is likely to result? a) Floc levels will diminish b) Solid material will not be effectively fitered out c) Methane production will go down d) Floc will not be effectivelyftered out

Answers

Answer:

The correct option is C

Explanation:

Anaerobic bacteria used in sewage treatment helps to reduce the volume/amount of sludge in the sewage thereby producing methane gas from it. Some companies produce there own (not for sale) methane gas (as an alternate source of energy) through this process. Thus, a decrease in the amount of this bacteria (perhaps through death as described in the question) will lead to a decreased production of methane gas.

Answers

Answer:

The reaction releases energy that is available to do work.

Explanation:

Endergonic reaction releases energy.

The following describes an exergonic reaction - The reaction releases energy that is available to do work.

Exergonic reaction:

In chemical thermodynamics, a chemical reaction where the change in the free energy is negative

Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy.Reactions with a positive ∆G (∆G > 0) require an input of energy and are called endergonic reactions.The equilibrium constant for an exergonic reaction is greater than 1, meaning it is not at equilibrium.

Thus, The following describes an exergonic reaction - The reaction releases energy that is available to do work.

Aerobic respiration has 3 stages: glycolysis, Kreb's cycle, electron transport
chain. What happens in each stage? How many ATP molecules made during
each stage?

Answers

What happens in each stage?

GLYCOLYSIS: "In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD+ is converted to NADH." (Khan Academy)

KREB'S CYCLE: "This is a central driver of cellular respiration. It takes acetyl CoA—produced by the oxidation of pyruvate and originally derived from glucose—as its starting material and, in a series of redox reactions, harvests much of its bond energy in the form of NADH, FADH2, and ATP molecules. The reduced electron carriers—NADH and FADH2—generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will generate most of the ATP produced in cellular respiration." (Khan Academy)

ELECTRON TRANSPORT: "In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient." (Khan Academy)

How many ATP molecules made during each stage?

GLYCOLYSIS: 2 ATP

KREB'S CYCLE: 2 ATP

ELECTRON TRANSPORT: 34 ATP

Khan academy is the best for breaking down processes in chemistry! I used khan all the time when I had trouble understanding chemistry last year.

Stage 1: Splitting Glucose stage
The word glycolysis initially means “glucose splitting,” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also known as pyruvic acid).

Stage 2 The Krebs Cycle

Recall that glycolysis produces two molecules of pyruvate (pyruvic acid). These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle. This cycle is at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process. It is also a central hub in biosynthetic reactions, providing intermediates that are used to build amino acids and other molecules. The citric acid cycle enzymes are found in all cells that use oxygen, and even in some cells that don't. The examples included here are taken from several different organisms.

Electron Transport Chain Stage.

The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

When a mitochondrial chaperone helps a mitochondrial matrix protein into the matrix by biased diffusion, the chaperone is said to be acting as ______.

a. Brownian motion
b. biased diffuser
c. Brownian ratchet
d. misratchet
e. unbiased diffuser

Answers

Answer:

c. Brownian ratchet

Explanation:

Mitochondria are cell organelles. They are known as the power house of the cells. The energy needed to power the cell is generated by the mitochondria. They functions like a digestive system.

The mitochondria chaperone are proteins that helps the proteins along pathways for their folding. They shield the proteins from other proteins and protect them from binding the folding process. The chaperone are mainly concern with the folding of protein.

The chaperone acts as a Brownian ratchet as the mitochondrial chaperone guides the matrix protein into matrix by the biased diffusion process.
