Tetracycline selectively transport into bacterial cells makes it essentially non toxic for mitochondrial 70s ribosome.

Tetracyclines, which include tigecycline, doxycycline, and tetracycline, are a class of drugs used to manage and treat different bacterial infections. Antibiotics known as broad-spectrum tetracyclines are classified as protein synthesis inhibitors.

Infections can be treated with tetracyclines, and they can also assist to manage acne. According on your doctor's assessment, demeclocycline, doxycycline, and minocycline may also be utilized for further issues. Tetracyclines are ineffective against the common cold, the flu, or other viral diseases.

Tetracyclines impede the aminoacyl-ability tRNA's to attach to the acceptor site on the mRNA-ribosome complex by reversibly binding to the 30S ribosomal subunit once they have entered the cell. The result is a bacteriostatic effect due to the inhibition of protein synthesis.

Answers

During Krebs cycle, Acetyl-CoA enters the cycle and then combines with oxaloacetate to make the six-carbon compound citric acid. this compound then undergoes several reactions which release CO₂ as waste, NADH and FADH₂ to move onto the next stage of respiration, and energy in the form of ATP. A single glucose molecule releases two molecules of ATP, two molecules of NADH, and molecules of FADH₂ because two molecules of pyruvate are created from each molecule of glucose .

The citric acid cycle (CAC), often referred to as the Krebs cycle, is a set of chemical processes that oxidizes acetyl-CoA, which is produced from carbs, lipids, and proteins, to release stored energy. Instead of fermenting, organisms that respire use the Krebs cycle to produce energy, whether through anaerobic or aerobic respiration. The cycle also supplies precursors of certain amino acids and NADH, a reducing agent that is employed in a variety of other processes. It was likely one of the oldest elements of metabolism and may have come about abiogenically given its prominent role in numerous metabolic processes.

Despite being referred to as a "cycle," it is not essential for metabolites to travel along a single path; at least three more stages of the citric acid cycle have been identified.

the haber process is used to create ammonia as an industry standard. in order to create the largest amount of product possible, they allow the reaction to come to equilibrium and then cool the reaction quickly. use your knowledge of intermolecular forces to explain why this is deemed the best way to proceed with the reaction.

Answers

The Haber process is run at a high temperature and then quickly cooled in order to optimize ammonia output. As a result, the ammonia gas is trapped in the liquid phase, where there is less chance that it may decompose.

A force that attracts the protons or the positive components of one molecule to the electrons or negative components of another molecule is known as an intermolecular force.

The equilibrium constant rises when the Haber process is carried out at high temperatures. This is because the heat energy makes the reactants more reactive by helping to break their bonds. However, the ammonia gas also has a tendency to break down into hydrogen and nitrogen gas at high temperatures.

The Haber process heavily relies on intermolecular forces. Weak intermolecular interactions draw the hydrogen and nitrogen molecules together. These forces are overpowered at a high temperature, allowing the molecules to react to produce ammonia. The ammonia molecules are less likely to disintegrate as the temperature is reduced because the intermolecular interactions are stronger.

Therefore, explanation given above best explains why the given process is deemed the best way to proceed with the reaction.

Native fauna and flora are directly harmed by rabbit damage and competition for food and shelter. They destroy vegetation through their burrowing and browsing, which can cause soil erosion and slope instability.

a. chromosomes line up at the equator
b. homologues line up in meiosis I and duplicated chromosomes line up in meiosis 2
c. sister chromatids line up in meiosis 1 and chromosomes line up in meiosis 2
d. there are the same number of chromosomes

Answers

Answer:

b. homologues line up in meiosis I and duplicated chromosomes line up in meiosis 2

Explanation:

During meiosis I, homologous chromosomes (one from each parent) line up at the equator, also known as the metaphase plate. This is called synapsis, and it ensures that each of the resulting daughter cells receives one copy of each chromosome. During meiosis II, the chromosomes that have already been separated during meiosis I, line up at the equator and the sister chromatids are separated into the daughter cells.

Meiosis I and meiosis II both have the same number of chromosomes in the daughter cells but the difference is that in meiosis I the homologous chromosomes are separated and in meiosis II sister chromatids are separated.

Cellular differentiation progressively restricts cell fate because the unexpressed genes in the cell:a. become more densely packed with nucleosomes.b. accumulate point mutations.c. accumulate deletions.d. accumulate both point mutations and deletions.e. undergo increasing repression.

Answers

Cellular differentiation progressively restricts cell fate because the unexpressed genes in the cell undergo increasing repression.

What do you mean by repression?

Repression is a psychological defense mechanism whereby a person unconsciously blocks unacceptable thoughts, feelings, and memories from their awareness. It can involve the denial or suppression of desires and impulses, or even the distortion or transformation of such desires into more acceptable forms. Repression is a defense mechanism that is used to keep potentially threatening or uncomfortable information out of conscious awareness.

Cellular differentiation is the process by which a single cell divides, resulting in two or more specialized cells that have different functions. As this process occurs, the cell's gene expression profile changes, with some genes becoming more active and others becoming increasingly repressed. This is done in order to ensure that the cell will be able to specialize in performing certain tasks and that it will not become confused and perform the wrong function. As the cell's gene expression profile changes, the number of genes that are expressed reduces, restricting the range of functions the cell can perform. This increasing repression of genes restricts the cell's fate and ensures it will specialize in performing a specific task.

The speed of sound in steel is greater than it is in air because
steel is
a. more elastic than air
b. less elastic than air
c. more dense than air
d. less dense than air

Answers

Answer:

Option A

Explanation:

The more elasticity the medium has, the more speed the sound travels. The density of steel is more than air because molecules are closer together in solids than in liquids or gas.

In general, sound waves in steel travel 17 times faster than through air. The speed of sound is determined by the dynamic propagation of sound waves. The speed of sound depends on elasticity and density and here both the elasticity and density of steel are more than air.

Hence, "The speed of sound in steel is greater than it is in the air because steel is more elastic than air".

Find andinterpret the key features of the graphin the context of the situation.The vertex is located at ( , )This means that the maximum height of the ramp is _ feet when the distance from one side is _ feet. Because the distance cannot be negative, and the ramp is _ feet long, the relevant domain is {x | 0 x __}.Because the height cannot be negative, and the ramp is _ feet tall, the relevant range is {y | 0 y __ }. The graph is symmetric in the line x = _ This means that the height from a distance of 0 to _ feet away from one side of the ramp is the same as the height from a distance of _ to _ feet away from one side of the ramp. pspg is requesting you stay out of the area and shelter in place until further notice. Which of the following is not a defining feature of an organisation? A weight attached to the end of a long spring is bouncing up and down. As it bounces, its distance from the floor varies sinusoidally with time. You start a stopwatch. When the stopwatch reads 1.7 seconds the spring is 58 cm above the floor and is on a downward path. It takes 4.4 seconds for the spring to bounce from a distance of 36 cm to 80 cm above the ground.A. Write an equation expressing distance from the floor in terms of the number of seconds the stopwatch reads B. Predict the distance from the floor when the stopwatch reads 6 seconds C.
