What do you think is the evolutionary significance of DNA polymerase? What do you think would happen if there was a genetic mutation on the genes encoding for DNA polymerase?

Answers

Answer 1

Answer:

Evolutionary significance of DNA polymerase: DNA polymerase is a key enzyme of DNA replication. During replication, it duplicates the DNA strand which then moves to next-generation, thus, continuing the life generations after generation.

If there will be a mutation in DNA polymerase, the nature of mutation would define the consequences. If it is a NEUTRAL mutation, it would not affect the action of DNA polymerase. However, if it a POSITIVE mutation, it may improve the function of DNA polymerase. On the other hand, if the mutation is NEGATIVE, it can be very harmful to living organisms because negative mutation can impair the function of enzyme thus stopping the DNA replication. This would most likely seize the life on Earth.

Answer 2
Final answer:

DNA polymerase plays a vital role in DNA replication, ensuring accurate transmission of genetic information. A genetic mutation on the genes encoding for DNA polymerase can compromise the fidelity of DNA replication and lead to the accumulation of harmful mutations.

Explanation:The Evolutionary Significance of DNA Polymerase

DNA polymerase is an essential enzyme in the process of DNA replication. It catalyzes the synthesis of new DNA strands by adding complementary nucleotides to the growing chain during DNA replication.

The evolutionary significance of DNA polymerase lies in its accuracy and efficiency in replicating DNA. Its fidelity ensures that genetic information is faithfully preserved, allowing for the transmission of genetic traits from one generation to the next.

If there is a genetic mutation on the genes encoding for DNA polymerase, it can lead to a compromised fidelity of DNA replication. This can result in a higher rate of errors during DNA replication, leading to the accumulation of mutations in the genome. These mutations can potentially have detrimental effects on the organism, including genetic disorders, diseases, or reduced survival and reproductive fitness.

Answers

By the end of prophase in Mitosis, each of the following has occurred except lining up of the chromosomes in the cell.

Explanation:

Prophase is divided into 2 phases early and late prophase.

Early prophase: The nuclear membrane starts dissociating, centrioles starts to migrate to the opposite poles, chromatin fibres (4) becomes thicker and condensed,

Late Prophase: From the centrioles that are at the opposite poles, Spindle fibres and 2 astral rays are formed. The spindle fibres get attached to the chromosomes.

The prophase will be followed by the metaphase, the chromosomes formed will be adjusted at the equatorial plate.

The description 'lining up of chromosomes in the cell' does NOT occur by the end of prophase.

Mitosis is a cell division by which one cell is divided to generate two genetically identical daughter cells.

This type of cell division has four main stages: prophase, metaphase, anaphase and telophase.

During prophase, the chromatin condenses, the nuclear envelope disintegrates, the nucleolus disappears and centrioles move to opposite ends of the cell (animal cells).

During metaphase, the chromosomes align at the equator plate of the cell in order to travel to opposite poles in anaphase.

In conclusion, the description 'lining up of chromosomes in the cell' does NOT occur by the end of prophase.

Which of the following is a true statement about the flow of energy in an ecosystem?
a. Smaller organisms need less energy per gram of body weight than do larger organisms.
6. Energy transfer between organisms normally involves conservation of heat energy.
C. Energy is lost between trophic levels.

Answers

Energy is lost between trophic levels.

Answer:  Option C

Explanation:

The source of energy for all organisms is the Sun. The Tropic levels exhibit the flow of energy in an ecosystem. The flow of energy is always in one direction. The energy level decreases crossing each trophic level as energy is lost in the form of heat.

Primary producers are the first in Trophic level, The Herbivores fall in the next level , the Carnivores form the next level and the decomposers are the last in the trophic level. The decomposers decompose all the living organisms and convert to nutrients that are available in the soil. The plants take up this nutrient and hence this is a cycle.

Explanation

"Physical and chemical barriers" is first line of defence includes  that are  ready to defend the living organism's body from infection at any time . These barriers include your skin, cilia, tears, urine flow, mucus, stomach acid, friendly bacteria and white blood cells . Skin acts as a mechanical barrier as it does not allows all the organism to pass through it unless the skin is cut or open. Similarly mouth eyes, and nose are also the ways through with the disease causing organism can enter the body. The micro-organisms that entered through these pathways are trapped either in saliva or mucus and swallowed and later either killed in the stomach or flushed out via the urine. If this first line of defence is broken or damaged, the second line of defence inside our body will be activated.

Question 2:

Histamine kinins, and interleukins are examples of inflammatory mediators.

Explanation:

Inflammatory mediators are identified in inflammatory bowel disease IBD.These mediators play an vital role in the clinical and pathologic characteristics of the disorders. Cytokines, that are released by macrophages in due to antigenic stimuli, are binded different receptors and produce endocrine, autocrine and paracrine effects.  Interleukins are a subset of a large group of 'cellular messenger molecules' called cytokines that modulates the cellular behaviour. Interleukins are not stored within cells like cytokines but they are released immediately, in response to a stimulus. Once an interleukin has been secreted, it moves to the target cell and binds to it through a receptor molecule on the surface of the cell . This interaction triggers a sequence of  signals in the target cell that ultimately leads to the alteration in the behaviour of the cell.

Which property of water remains unchanged when it recycles in the atmosphere

Answers

Answer:

Molecular arrangement is the property of water remains unchanged when it recycles in the atmosphere .

Explanation:

In the water, Molecular arrangement remains same when it recycles in the atmosphere . A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent.

This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other.  Thus it is the element or property which remains in same condition.

The chemical composition of water, specifically the molecular structure of H₂O, remains unchanged during the water cycle as it moves through the atmosphere, despite undergoing phase changes.

The property of water that remains unchanged when it recycles in the atmosphere is its chemical composition. Each water molecule, consisting of two hydrogen atoms and one oxygen atom (H₂O), maintains this structure throughout the water cycle, regardless of the physical state it may be in (solid, liquid, or gas). Despite continuous phase changes such as evaporation, condensation, and precipitation, the intrinsic molecular structure of water does not alter. Water's unique properties, including its high specific heat and density anomaly where solid water (ice) is less dense than liquid water, play crucial roles in weather systems and the environment without changing the actual H₂O molecule.

As water evaporates, forms clouds, and returns as precipitation, it moves energy through the atmosphere, driving weather patterns. The vast amount of energy required for the temperature of water to change protects our climate by absorbing and releasing heat at a slower rate. This characteristic also significantly impacts Earth's weather, as it allows water to store heat, influencing weather events like hurricanes. Despite these changes in state and temperature, the chemical composition of water remains consistent during the hydrologic cycle.

Answers

Answer:

Hello!

The answer is D) Homeostasis

Explanation:

Homeostasis:

The regulation of a cell or an animal's internal environment in response to fluctuations in the external environment is called homeostasis.

Homeostasis is crucial to maintain an optimum environment for cell structures to work effectively.

In this case, the jackrabbiit's circulatory system is responding to fluctuating temperatures. In hot days, the body is at risk of heating up above optimum temperature which could hamper body functions. Therefore, the blood flow to the ears is increased to facilitate heat loss.

In cold temperatures, the blood flow to the ears is decreased to conserve heat for vital body organs. The blood flow is directed to the core of the body to protect the heart, lungs, liver and brain.

Final answer:

The jackrabbit's circulatory system adapts to temperature changes by regulating blood flow to its ears, directly relating to homeostasis, which maintains a stable internal environment in varying temperatures.

Explanation:

The jackrabbit's circulatory system facilitates the regulation of body temperature, a phenomenon known as homeostasis. On hot days, vasodilation occurs, increasing blood flow to the jackrabbit's ears where heat can be dissipated through radiation and evaporative cooling. Conversely, on cooler nights, vasoconstriction minimizes blood flow to the ears to conserve body heat. This pattern directly relates to homeostasis because it is a way for the organism to maintain a stable internal environment despite the varying external temperatures.

Answers

OA) sugars and phosphates; nitrogen bases
Final answer:

The rails in the twisted ladder model of DNA represent the sugar-phosphate backbones and the rungs represent the pairs of nitrogen bases. The correct answer to the student's question is OA) sugars and phosphates; nitrogen bases.

Explanation:

In the classic double helix model of DNA, the "rails" of the twisted ladder are made up of the sugar-phosphate backbone, while the "rungs" correspond to the pairs of nitrogenous bases. Each nucleotide, which is the basic building unit of DNA, consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base. The backbone structure is formed by the sugar of one nucleotide connecting to the phosphate group of the next, creating a long chain that makes up the sides of the ladder. The nucleotides from one strand connect to those of a complementary strand via hydrogen bonds between their nitrogenous bases, which form the rungs of the ladder with adenine (A) always pairing with thymine (T), and guanine (G) always pairing with cytosine (C).

Therefore, the correct answer to the question is: OA) sugars and phosphates; nitrogen bases. The sugars and phosphates form the structure of the double helix, and the nitrogen bases interact in the middle, creating base pairs that hold the two strands together like the steps of a ladder.

B) Glycine
C) Both (a) & (b)
D) None of these

Answers

Answer:

Hi!

The answer is (C) Both (a) and (b)

Explanation:

Drug Metabolism:

Drug metabolism is divided into two steps: Phase 1 and Phase 2 reactions. Phase 1 reactions involve the degradation or formation of functional groups.Phase 2 reactions involve the conjugation of the drug or its Phase 1 intermediate with a polar conjugating molecule. Phase 2 generally performs the detoxification step in the drug degradation process. Phase 2 or conjugation reactions are further divided into 2 types: Type 1: Glucoronidation and sulfonation: An activated conjugating molecule such as glucoronic acid, sulfate or glutathione etc. is combined with the drug to form a conjugated molecule. Type 2: Amino acid conjugation: An activated drug or substrate is conjugated with an amino acid such as glycine or glutamine.

Glutathione Conjugation:

Glutathione is a tripeptide found in most tissues, particularly in the liver. It performs important detoxification functions for all cells. The enzyme, glutathione S-transferase conjugates glutathione with drug intermediates to form a drug-glutathione conjugate. This conjugate can easily be excreted through bile or urine.

Amino acid Conjugation:

This is an important reaction in xenobiotic biotransformation; particularly for xenobiotics with carboxylic group or an aromatic hydroxylamine groups. Drug intermediates combine with glycine or glutamine to form an amino acid conjugate.

Explanation:

Urban sprawl is the process by which urbanization is taking place by destroying forests and constructing buildings and cities. The owl is a nocturnal bird that sleeps during the day and preys at night. The owl feeds on small rodents, grasshoppers, snakes etc. They live in trees, farmlands, prairie, etc.

If the forests are cut, the trees where the owls reside will be lost. They will become homeless and will have to move elsewhere to find food.

Since they feed on rodents, these rodents hide in the grass and under the trees. If the grass and trees are destroyed to make roads and buildings, the owl will remain hungry and will eventually die if it does not relocate.

What is diffusion?

Diffusion refers to the motion of molecules from a region of high concentration to the region of low concentration. By doing so, the molecules of the substance will try to attain equilibrium. Hence, they will try to equalize their concentration on both the sides of the membrane.

Diffusion occurs in all the living beings, which facilitates the movement of substances or molecules in and out of the cell under a concentration gradient.

It is mainly of 2 types: Simple diffusion where it occurs simply without the help of any facilitators, while facilitated diffusion where the diffusion occurs with the help of solute-specific facilitators or carrier proteins.

The substances which are in the liquid and gaseous phases readily undergo diffusion due to the presence of intermolecular spaces between them.

Thus, the correct option is A. The molecules constantly move and collide with each other and cause diffusion.
