During dna replication in a bacterium a g is mistakenly inserted into the newly-synthesized dna strand opposite a t in the template dna strand. if this mistake is not repaired before the next round of dna replication, what mutation will eventually result?

Answer:

D) The air pushes the balloon in the opposite direction.

Explanation:

When the balloon bursts the air pushes the balloon in the opposite direction to the air that was released from inside the balloon. This is because of the difference between the atmospheric pressure and the pressure that was inside the balloon. When the balloon bursts, the pressure gradient causes a force that causes the air inside the balloon and the balloon to be pushed in opposite directions.

Answer:

Opiates

Explanation:

Opiates are the chemicals that are obtained by the modification of natural opium components. High amount of opiates in the body can cause death of an individual.

Opiates are used to reduce pain, euphoria , produces the sense of well being and constipation. Regular use of opiates can cause addiction in the organism.

Thus, the answer is opiates.

The biodiversity of the Earth’s vegetation makes up its beauty especially the grassland which is covered mostly of trees and grasses.  There are a lot of varieties of grassland and among of which is savanna grassland where we can find perennial grasses and the flowering plant called forbs.

ATP synthase uses a proton gradient to restore ADP to ATP in a process known as chemiosmosis, which takes place during oxidative phosphorylation.

The process by which ATP synthase uses a proton gradient to restore ADP back to ATP is called chemiosmosis. This occurs during oxidative phosphorylation, a key part of cellular respiration where the energy stored in the electrochemical gradient, developed due to the movement of protons (H+), is utilized. As protons flow through ATP synthase, much like water flowing through a turbine, they provide the energy needed for the enzyme to catalyze the production of ATP from ADP and inorganic phosphate (Pi).

Answer:

c

Explanation:

A doctor prescribes a 500-mg antibiotic tablet to be taken every eight hours. just before each tablet is taken, 20% of the drug remains in the body.

(a)    how much of the drug is in the body just after the second tablet is taken?

600 mg

after the third tablet?

720 mg

(a) After the second tablet: 600 mg. After the third tablet: 620 mg.

(b) Equation: [tex]\(Q_{n+1} = 0.2Q_n + 500\)[/tex].

(c) Long-term quantity: 0 mg.

(a) To find the quantity of the drug in the body just after the second tablet is taken, we need to consider the elimination of the drug over time and the intake of the second tablet.

The quantity of the drug remaining in the body after the first tablet is 500mg.

After 8 hours, 80% of the drug is eliminated, leaving [tex]\(20\% = 0.2\)[/tex] of the drug in the body.

Thus, after 8 hours, the quantity of the drug remaining in the body is [tex]\(0.2 \times 500 = 100\)[/tex] mg.

When the second tablet is taken, another 500 mg of the drug is added to the quantity remaining in the body.

So, after the second tablet is taken, the total quantity of the drug in the body is 100 + 500 = 600 mg.

Now, to find the quantity of the drug in the body just after the third tablet is taken, we repeat the process:

After another 8 hours, 80% of the drug is eliminated from the body, leaving 20% = 0.2 of the drug in the body.

Thus, after another 8 hours, the quantity of the drug remaining in the body is [tex]\(0.2 \times 600 = 120\[/tex]) mg.

When the third tablet is taken, another 500 mg of the drug is added to the quantity remaining in the body.

So, after the third tablet is taken, the total quantity of the drug in the body is 120 + 500 = 620 mg.

Therefore, after the second tablet is taken, there are 600 mg of the drug in the body, and after the third tablet is taken, there are 620 mg of the drug in the body.

(b) Let's denote [tex]\(Q_n\)[/tex] as the quantity of the antibiotic in the body just after the nth tablet is taken.

To find an equation expressing [tex]\(Q_{n+1}\)[/tex] in terms of [tex]\(Q_n\)[/tex], we observe that after each tablet is taken, the quantity of the drug in the body increases by 500 mg. Additionally, after each 8 hours, 80% of the remaining drug is eliminated.

So, the equation expressing [tex]\(Q_{n+1}\)[/tex] in terms of [tex]\(Q_n\)[/tex] is:

[tex]\[Q_{n+1} = 0.2 \times Q_n + 500\][/tex]

(c) In the long run, the quantity of the antibiotic in the body will stabilize when the amount of the drug taken in equals the amount eliminated.

Let's denote the long-term quantity of the antibiotic in the body as [tex]\(Q_{\text{long}}\).[/tex]

According to the equation derived in part (b), after each tablet is taken, the quantity of the drug in the body increases by 500 mg. However, after each 8 hours, 80% of the remaining drug is eliminated.

So, in the long run, [tex]\(Q_{\text{long}}\)[/tex] will stabilize when the amount taken equals the amount eliminated:

[tex]\[0.2 \times Q_{\text{long}} + 500 = 500\][/tex]

Solving for [tex]\(Q_{\text{long}}\):[/tex]

[tex]\[0.2 \times Q_{\text{long}} = 0\]\[Q_{\text{long}} = 0\][/tex]

Therefore, in the long run, no quantity of the antibiotic remains in the body.

The complete question is here:

A doctor prescribes a 500 mg antibiotic tablet to be taken every eight hours. It is known that the body eliminates 80% of the drug in eight hours. (a) How much of the drug is in the body just after the second tablet is taken? After the third tablet?

second tablet X mg

third tablet X mg in terms of

(b) If Q, is the quantity of the antibiotic in the body just after the nth tablet is taken, find an equation that expresses Qn + 1  in terms of Qn

(c) What quantity of the antibiotic remains in the body in the long run? mg

Answer:

Keratin is a protein.

Explanation:

Keratin is a fibrous protein that has the characteristics of rigid conformation, elasticity and impermeability to water. It has animal origin and is found in the vertebrate epidermis and in some epidermal appendages, such as hair, nails, hooves, feathers and scales. This protein is produced in cells called keratinocytes, which are the most abundant in the human epidermis.

Like any protein, keratin is made up of amino acids. It has a large amount of cysteine residues, which is responsible for 7% to 20% of the total amino acids present in keratin. Note that cysteine is mainly located in the terminal region of the keratin chains.

Finger contusion can be characterized by bruising of finger, where there is swelling and bleeding under the skin but no broken bones.

1. Diagnosis and Management:- Contusion of finger is diagnosed by the symptoms such as pain, swelling, discoloration, tenderness and difficulty in movement. Sometimes numbness is associated as swelling compresses the nerves in that region.X-ray (If required CT scan0 can be done to confirm the diagnosis and rule out fractures and other serious forms of injuries.

Depending upon the severity, treatment is decided. The contusion is managed with an aim to reduce pain, swelling and restore the movement. The options so as to treat the contusion, based on its severity are as follows

a. Applying Icepacks and keeping the finger propped up above the heart level.

b. Splinting and taping

c. Physiotherapy

d. Ultrasound therapy

e. Surgical treatment is required in case of torn ligaments.

These options of treatment are accompanied with over the counter pain killers and anti inflammatory drugs

AraC protein certain to the ara operator works as a repressor that avoid transcription of the same ara operon and the araC gene AraC protein is an activator in the presence of arabinose and repressor in the absence of arabinose -With arabinose absent, the AraC protein stays as
a homodimer. One AraC protein put together to the ara initiator and the other protein now binds to a different regulatory site in DNA called the ara operator.

Answer:

3. Proteins

Explanation:

Enzymes are naturally occurring groups of organic substances of protein origin (they can be form by 62 amino acid residues, such as 4-oxalocrotonate tautomerase enzyme monomer to 2500 residue size) with intra or extracellular activity that have catalyst functions. This is achieved by lowering the activation energy to allow a chemical reaction, resulting in an increased reaction speed and allowing the metabolism of living things. Importantly, although most enzymes are proteins, there are also enzymes consisting of RNA as ribozymes.

The term mitosis does not apply to prokaryotes since, it involves nuclear division and eukaryotic structures.

It is important because the body needs energy from glucose, glycogen phosphorylate, with the help of an orthophosphate, can cleave away a molecule from the glycogen chain. The cleaved molecule is in the form of glucose-1-phosphate, which can be change into G6P phosphate.

New types of glue have been developed from mussels, heat-resistant enzymes from deep-sea bacteria have industrial applications, and fluorescent compounds from coral and jellyfish can be used commercially as fluorescent dyes.

Answer:

The correct answer is Y - glucose, Z - oxygen

Explanation:

In photosynthesis, plants- and also other organisms- take carbon dioxyde (CO₂), water (H₂O) and light (which is absorbed by chlorophyll pigments, those give plants their green color), and they convert inorganic materia in organic materia (chemical energy) in form of sugar. The overall process is described by the following global equation:

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → glucose + oxygen

In the diagram, the equation is:

carbon dioxide + water + sunlight → glucose + oxygen

Answer:

The correct answer is A.

Explanation:

Y represents Glucose, a product of cellular respiration. Z represents Oxygen, which is also a product of cellular respiration.

(CO2 + Water + Sunlight = Glucose and Oxygen)
