Answer:

C. CH4 + 202 – CO2 + 2H20

Explanation:

CH4+O2-CO2+H20

The above equation represents combustion of methane to produce carbon-dioxide and water.

One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side  and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.

The balanced chemical equation is:

CH4+202-CO2+2H2O

This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.

Answer:

C. CH4 + 202 – CO2 + 2H20

Accumulation of a large amount of H+ between the inner and outer mitochondrial membranes, is described as Chemiosmosis.

Chemiosmosis is the mechanism through which cellular respiration really produces ATP . Protons are pumped from the inner to the outer compartment of the mitochondria by means of specific channels in the membranes. A proton (H+) gradient is established by the pumping. Protons diffuse down the gradient once it has been generated using a transport protein called ATP synthase. A phosphate and ADP are coupled through the action of hydrogen ions, creating ATP. The respiration process in cells produces a significant amount of energy. The Krebs cycle processes, the electron transport system, and chemiosmosis all contribute to the production of 36 molecules of ATP for every glucose molecule during cellular respiration, according to the majority of biochemists.

Hence, hydrogen ion pumped out through ETS reaction as result of energy molecule synthesis.

Answer:

reverse transcription  

Explanation:

The central dogma of molecular biology states that the flow of the genetic information is unidirectional: DNA to RNA to protein. Thus, the central dogma indicates that a gene is always transcribed into a messenger RNA (mRNA) molecule, and then this mRNA is used as a template for protein synthesis during translation. Reverse transcription is an event that contradicts the central dogma since in this case there are enzymes known as reverse transcriptases that are capable of synthesizing DNA by using RNA as template. In eukaryotic cells, reverse transcription may occur naturally during the insertion of certain Transposable Elements (retrotransposons).

B cell maturation from a hematopoietic stem cell (HSC) to a mature B cell takes several weeks. Therefore, the correct answer is C) 1 to 2 weeks.

During the process of B cell maturation, HSCs give rise to progenitor cells that undergo a series of differentiation and maturation steps, culminating in the development of functional mature B cells. This process occurs in the bone marrow and involves the rearrangement and expression of the genes that encode the B cell receptor (BCR). The maturation process takes several weeks, during which B cells undergo multiple rounds of cell division, differentiation, and selection to ensure that they can recognize and respond to a diverse array of antigens.

Once mature B cells are generated, they leave the bone marrow and circulate through the bloodstream and lymphatic system, ready to encounter and respond to antigens. Therefore option C is correct.

Answer:Acidosis and alkalosis are medical conditions related to the pH balance of the body. The pH value of the body needs to be within a specific range in order for the body to function properly. Acidosis occurs when the pH of the blood drops below 7.35 due to an excess of acid in the blood. On the other hand, alkalosis occurs when the pH of the blood rises above 7.45 due to an excess of base in the blood.

Acidosis can be caused by several factors, including diabetes, kidney disease, lung disease, alcoholism, and certain medications. Symptoms of acidosis can include fatigue, confusion, shortness of breath, and a feeling of being generally unwell. Severe acidosis can lead to shock or coma and is a medical emergency. Treatment for acidosis involves identifying and treating the underlying cause. For example, if acidosis is caused by diabetes, controlling blood sugar levels can help treat the condition.

Alkalosis can be caused by several factors, including vomiting, prolonged vomiting or suctioning of the stomach, overuse of certain medications such as antacids, and conditions like lung disease, liver failure, and congestive heart failure. Symptoms of alkalosis can include confusion, muscle twitches, and a tingling sensation in the fingers and toes. Treatment for alkalosis typically involves identifying and treating the underlying cause. For instance, if alkalosis is caused by vomiting, treating the underlying cause of the vomiting can help resolve the condition.

In some cases, medical intervention may be necessary to correct acidosis or alkalosis. For instance, in severe cases of acidosis, bicarbonate may be administered intravenously to help restore pH balance. In cases of severe alkalosis, treatment may involve discontinuing medications that contribute to the condition and administering intravenous saline or potassium chloride.

The six main things that happen in the boil are sanitization, hop addition, evaporation, coagulation of proteins, maillard reactions, and extraction of sugars and other compounds.

In sanitization, the boil kills off any harmful bacteria or microorganisms present in the wort, ensuring a clean fermentation process. Hop addition are added at various stages during the boil to provide bitterness, flavor, and aroma to the beer. Water evaporates during the boil, which concentrates the wort and helps achieve the desired original gravity for the beer.

In coagulation, proteins in the wort coagulate and form clumps called "trub," which can be removed after the boil to promote clarity and stability in the finished beer. Maillard reactions are the chemical reactions between amino acids and reducing sugars occur during the boil, contributing to the color and flavor development in the beer. Sugars and other compounds from the malt are extracted and dissolved into the boiling water, creating the basis for the final beer's body, color, and flavor profile.

Deuteromycotes

Explanation:

Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.

Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.

However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.

A community can develop in an area that is virtually lifeless and devoid of soil through a process called primary succession. A disturbance that wipes out a community without harming the soil is followed by secondary succession.

A climax community is produced by primary succession, whereas a destroyed community is produced by secondary succession. While secondary succession begins with an existing plant community, primary succession begins with bare rock.

Primary succession occurs in a location that has never before been home to a community. Newly exposed rock areas, sand dunes, and lava flows are examples of places where primary succession takes place.

Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.

The series of mitochondrial proteins that transfer electron energy to ATP and require oxygen is known as the electron transport chain (ETC).

The ETC is a critical component of cellular respiration and occurs in the inner mitochondrial membrane. It consists of a series of protein complexes, including NADH dehydrogenase, succinate dehydrogenase, cytochrome b-c1 complex, cytochrome c, and cytochrome oxidase. These complexes work together to transfer electrons derived from NADH and FADH2, which are produced during earlier stages of cellular respiration, and transfer them along the chain.

As electrons are passed through the protein complexes, energy is released and used to pump protons across the mitochondrial membrane, creating an electrochemical gradient. This gradient is then used by ATP synthase to produce ATP through a process known as oxidative phosphorylation.

The final acceptor of the electron transport chain is oxygen, which combines with hydrogen ions to form water. Thus, the ETC connects the process of electron transfer to the production of ATP, relying on oxygen as the final electron acceptor.
