What are the primary products of the complete combustion of fossil fuels?

Answers

Answer 1
Final answer:

The main products of the complete combustion of fossil fuels, like gasoline or methane, are water and carbon dioxide. Additionally, carbon monoxide and nitrogen oxides are produced in minor quantities. The release of carbon dioxide into the atmosphere as a result of burning fossil fuels contributes to global climate change.

Explanation:

The primary products of the complete combustion of fossil fuels, such as gasoline or alkanes like methane and butane, are carbon dioxide and water. This is a consequence of a highly exothermic oxidation-reduction reaction that occurs in the presence of oxygen. To a lesser degree, carbon monoxide and nitrogen oxides are also produced as emissions.

Upon burning fossil fuels, carbon dioxide is released into the atmosphere. This is a result of oxidation, where ancient coal and oil deposits are burned, using oxygen. The level of carbon dioxide in the atmosphere has been increasing significantly due to global industrial and agricultural developments, further exacerbated by deforestation.

While combustion of fossil fuels meets our energy needs, it is also recognized as a major contributor to global climate change.

Answer 2
Final answer:

The primary products of complete combustion of fossil fuels are carbon dioxide (CO2) and water (H2O).

Explanation:

Primary Products of Complete Combustion of Fossil Fuels

The primary products of complete combustion of fossil fuels are carbon dioxide (CO2) and water (H2O).

During the combustion process, the hydrocarbons present in the fossil fuels, such as methane (CH4) and propane (C3H8), react with oxygen (O2) to produce carbon dioxide and water.

For example, the complete combustion of methane can be represented by the chemical equation:

CH4 + 2O2 -> CO2 + 2H2O

Which process occurs during asexual reproduction? A. Crossing-over between homologues B. Mutation C. Separation of homologous pairs of chromosomes D. Separation of sister chromatid

Answers

Answer:

A. Crossing-over between homologues.

Explanation:

In meiosis and mitosis, recombination happens between comparable particles of DNA (homologous groupings). In meiosis, non-sister homologous chromosomes pair with each other so recombination ordinarily occurs between non-sister homologs.

All living organism reproduces either through asexual reproduction or sexual reproduction or sometimes through both mode of reproduction. In both cases let it be sexual or asexual, the mode of cell division namely meiotic and mitotic cell division, the recombination between homologous chromosomes is a typical system utilized in reproduction.  

The underwear in the image keeps you warm on cold nights because it A) keeps cold air out. B) is a poor insulator. C) is a good insulator. D) is a good conductor.

Answers

Prevents Conduction

Answer:

Option C,  is a good insulator

Explanation:

See the attached image of the  underwear

Solution

As it is clear in the image, the fabric of the underwear is poly fabric which acts as a good insulator.  

Being an insulator, it can easily trap the heat of the body during winters and does not allow this heat to escape due to which it is successful in keeping a person warm during the winters.  

If the material of the underwear would have been a conductor, it would have allowed heat of the body to escape.

Identify whether each circumstance provided will promote an increase or decrease in blood pressure

Answers

Circumstance that cause an increase in Blood Pressure:

- increasing levels of aldosterone ((influences the reabsorption of sodium and excretion of potassium in the kidneys. This will indirectly influence the blood pressure since the volume of blood will change)

- vasoconstriction ( blood vessels increase their contraction, which equals to more pressure)

-increased release of renin (Converts angiotensinogen, secreted in the liver, into angiotensin I).
- increased activity of Angiotensin-converting enzyme ( this enzyme converts angiotensin I into angiotensin II increasing vasoconstriction).

Circumstances that cause a Decrease in Blood Pressure:

- decreased sodium reabsorption ( by decreasing sodium, the amount of water will also decrease or , in other words,will be excreted. Less water, will decrease volume of blood and that means less blood pressure)

- vasodilation (The smooth muscle in the blood vessels decrease their contraction, which equals to less pressure)

- declining levels of ADH(ADH is produced in the hypothalamus and stimulates vasoconstriction plus it promotes water reabsorption in the kidneys. To reduce blood pressure, is important to have ADH levels reduced)

Compare in general terms the effects of epinephrine glucagon and insulin on glucose metabolism

Answers

Epinephrine and glucagon cause an increase in the blood glucose level. Epinephrine acts when a higher than normal level of glucose is required; glucagon acts when the level is unusually low. Both stimulate gluconeogenesis and glycogen breakdown and decrease glycolysis and glycogen synthesis. Insulin causes a decrease in blood glucose levels; it acts by increasing glycogen synthesis, glycolysis, and glucose uptake by cells as well as by decreasing glycogen breakdown.

which part of photosynthesis requires ATP, NADPH, and carbon dioxide to produce glucose

Answers

Final answer:

The Calvin Cycle or light-independent reactions of photosynthesis use ATP, NADPH, and carbon dioxide to produce glucose.

Explanation:

The part of photosynthesis that requires ATP, NADPH, and carbon dioxide to produce glucose is known as the Calvin Cycle, or the light-independent reactions. These reactions do not require light to occur and are responsible for the fixation of carbon dioxide into organic molecules. In the process of carbon fixation, CO₂ is 'fixed' from an inorganic to an organic form and then, using the ATP and NADPH generated from the light-dependent reactions, these fixed carbons are combined to form sugar molecules such as glucose.

The mutation will cause a translocation to occur.
The mutation will cause a change in the individual but it will not be inherited.
The mutation will be inherited by the offspring.
The mutation will not cause any change in the individual and it will not be inherited.

Answers

Hi,

If a point mutation occurs during which  CGA changes to AGA, the mutation will be simply inherited to the offspring and there won't be any harsh effects on the health of individual.

This is because, both AGA and CGA code for same amino acid called Arginine.

We know that mutations posses harmful effects when they change the genetic sequence leading to the incorporation of incorrect amino acid in the organisms and their offspring. But in this case the mutation will not be harmful and will simply be transferred to the offspring and will have no effect on the functioning, fitness or survival of the organism

Which abnormal skin growth results from a virus?

freckles

moles

warts

jaundice

Answers

Warts are caused because of a virus called HPV
Final answer:

Warts are the abnormal skin growths that result from a virus. While freckles, moles, and jaundice are also skin conditions, they are not typically caused by a virus. Instead, each has different causes such as sun exposure, genetics, and high levels of bilirubin respectively.

Explanation:

The abnormal skin growth that results from a virus is a wart. Warts are rough, usually skin-colored growths that appear on the skin and mucous membranes. They are caused by the human papillomavirus (HPV). The virus infects the top layer of the skin and causes it to grow quickly, leading to a wart. While freckles, moles, and jaundice can also be familiar terms related to skin conditions, these are not typically caused by a virus.

For instance, freckles aren't caused by a virus but are small, brownish spots on the skin that can appear as a result of sun exposure and genetics. Moles, which are small skin marks caused by pigment-producing cells in the skin, are mostly harmless and aren't typically caused by a virus. Meanwhile, jaundice is a result of high levels of bilirubin in the body and causes a yellowing of the skin and eyes, but it is not related to a viral infection.

Which condition feeds a tropical storm as it develops into a hurricane? A. heat and moisture B. cool temperatures and rain C. high temperatures and freshwater D. wind and dry air

Answers

A. heat and moisture

Hurricanes form over tropical waters (between 8 and 20 degrees latitude) in areas of high humidity, light winds, and warm sea surface temperatures [typically 26.5 degrees Celsius (80 Fahrenheit) or greater]. These conditions usually prevail in the summer and early fall months of the tropical North Atlantic and North Pacific Oceans, and for this reason, hurricane “season” in the northern hemisphere runs from June through November.


The first sign of hurricane genesis (development) is the appearance of a cluster of thunderstorms over the tropical oceans, called a tropical disturbance. Tropical disturbances generally form in one of three ways, all of which involve the convergence of surface winds. When winds come together (converge), the force of the collision forces air to rise, initiating thunderstorms.

What are thin and thick myofilaments made of?

Answers

Answer:

Composition of thin myofilaments:

                                                     The proteins in thin filaments are actin, tropomyosin, and troponin.

Composition of thick myofilaments:
                                                   Thick filaments are composed of protein myosin only. 
Final answer:

Thin myofilaments are made up of the protein actin, meanwhile thick myofilaments are composed of the protein myosin. These two are key players in muscle contraction.

Explanation:

In muscular biology, the terms thin and thick myofilaments reference the protein structures that enable muscle contraction. Thin myofilaments are primarily composed of the protein actin, along with two other proteins, tropomyosin and troponin. Thick myofilaments, conversely, are made of another protein called myosin. These myofilaments slide past each other to cause muscle contraction, a process known as the sliding filament theory.

d. sperm.
e. all of these.

Answers

The correct answer is D. sperm

If the ductus deferens tubes are cut and tied, the semen will not contain sperms. This is known as vasectomy. This procedure is performed in males to control population. Thus, the correct option is D.

What is Vasectomy?

Vasectomy is the permanent male sterilization procedure. It is a surgical procedure which involves the cutting or sealing of the ductus deferens tubes which carries a man's sperm to permanently prevent pregnancy. It is usually carried out by giving a local anesthetic to the client, where the man is awake but could not feel the pain, and this procedure complete in about 15 minutes.

Once the tubes are cut, sperms cannot enter into the semen of man or out of the body. However, the testes do produce sperms, but the sperms die and absorbed by the body. A man who have undergone a vasectomy still produces the semen and is also able to ejaculate it. But, the semen contains everything except sperms.

C. the breeder performs the cross and finds half of the f1 progeny have black fur and half have white fur. what was the genotype of the mouse with black fur that she started with in the p0 generation?

Answers

The only way this works is if the 2 parents are both heterozygous for fur color. So each parent is Ff (I'm using F for fur color where F is black and f is white).

The two Ff parents would have had to come from two parents that had FF and ff as their genotypes (so a homozygous black mouse and a homozygous white mouse). 

You can check these by Punnet Square starting with the p0 generation and cross FF and ff; you get all Ff.
Then do another Punnet Square crossing Ff with Ff and you get 50% progeny Ff (black) and 50% ff (white).
