A student proposes that when burning isopropyl alcohol (C3H8O) - the same TWO products will be made as when they burned ethanol in class.
1a. What PRODUCTS should she expect to have and what EVIDENCE should she expect to observe or measure to show that those two products were formed?
Your answer should have TWO products (what comes OUT after burning isopropyl alcohol), and what could be observed in an experiment to provide evidence that each of those came out.

I'll give you the brainliest

Answers

Answer 1

Answer:

See explanation

Explanation:

The equation for the combustion of isopropyl alcohol is shown below;

C3H8O+9/2 O2→ 3CO2+4H2O

Now our task is to carry out a simple test to confirm that both carbon dioxide and water vapor are products of the reaction.

Test for CO2:

If the products of the reaction are bubbled into lime water, the lime water gradually turns milky. This confirms the presence of CO2 as one of the products of the reaction.

Test for H2O:

If the products of the reaction are passed over white anhydrous copper II sulphate, the anhydrous crystals turn blue to show that water is present.

The enzyme threonine deaminase, in addition to being controlled by feedback inhibition, is controlled by _____.

Answers

Answer:

noncompetitive inhibition

Explanation:

Non-competitive inhibition (also known as allosteric inhibition) is a type of enzymatic reaction where an inhibitor binds to the enzyme and thus reduces its enzymatic activity. Non-competitive inhibitors are known to bind with the enzyme at allosteric sites, i.e., at different sites rather than the active site. In consequence, during non-competitive inhibition, the substrate can still bind to the enzyme, although that binding to the inhibitor reduces its catalytic efficiency. Conversely, competitive inhibition is produced when the inhibitor binds to the enzyme at the active site, thereby preventing from binding to the substrate.

Genes C and D are linked with a recombination frequency of 0.4. Both genes segregate dominant (C and D) and recessive alleles (c and d). The parental cross CCDD x ccdd is performed and then the F1 progeny is testcrossed to ccdd. If 10 individuals are counted in the F2, how many are expected to be dominant for BOTH genes

Answers

Answer: 3 individuals.

Explanation: Recombination frequency is the proportion of offspring who will inherit the recombinant genes.

The F1 progeny has genotype CcDd. When crossed with an individual with genotype ccdd, F2 generation can be CcDd or ccdd in a 50/50 probability.

The recombinant frequency is 0.4, which means in a total of 10 individuals of F2, 4 will be recombinant, so 6 will be parental, i.e., will carry the same genes of their parents.

From the population of 6, half of them will carry dominant genes for both features, so:

6 x 0.5 = 3

Therefore, from 10 individuals of F2, we expected 3 to be dominant for both genes.

The atmospheric carbon change that will be witnessed in 1, 10, and 100 years will be 854, 890, and 1250 years.

Carbon is an important element for all the firms of life that are on Earth. It should be noted that life forms take in carbon to manufacture food and also release carbon that's needed for respiration.

The intake and output of carbon are important to plant and animal life. The atmospheric carbon change that will be witnessed in 1, 10, and 100 years will be 854, 890, and 1250 years. Climatic change has been a factor in the increase in the amount of carbon dioxide that's in the atmosphere.

Dinitrophenol (2,4-DNP) destroys proton gradients without affecting anything else about a membrane. Its pKa slightly acidic, so it can be protonated or unprotonated in cells.a. What would be the effect of adding dinitrophenol to the mitochondrial inner membrane

Answers

Answer:

the effect of adding dinitrophenol to the mitochondrial inner membrane is -:

Production of ATPNo electron transferproduction of more sugar as energyUncoupling of ETC(electron transport chain)

Explanation:

Dinitrophenol is an uncoupler which can isolate the progression of electrons and siphoning of H+ particles for ATP Synthesis. On adding the dinitrophenol, the energy from the electron move can't be utilized for ATP blend. It has been utilized in diet pills and as a counting calories help. It goes about as protonophore and permits spillage of the protons through the internal mitochondrial layer which subsequently sidesteps ATP synthase and consequently the creation of ATP creation gets wasteful. It hinders the ATP synthase and thus its capacity to deliver ATP. It likewise influences the ETC in light of the fact that forestalls development of electrons over the ETC. Uncoupling the ETC would prompt diminished ATP creation and consequently increasingly more sugar is used as energy. This would restrict accessibility of ATP and make a deadly circumstance.

8. What abiotic factors distinguish different biomes?

Answers

Temperature and precipitation, and variations in both, are key abiotic factors that shape the composition of animal and plant communities in terrestrial biomes. Some biomes, such as temperate grasslands and temperate forests, have distinct seasons, with cold weather and hot weather alternating throughout the year

The abiotic factors like temperature, precipitation (rainfall), and the intensity of wind are primarily responsible for distinguishing different biomes.

What are Biomes?

A biome may be defined as a very large ecosystem that is running in nature in an unmanaged way. In a more simple sense, it is a very large area that is characterized by a particular type of vegetation. Some examples of biomes include tropical rainforests, coral reefs, grasslands, etc.

In tropical rainforests, rainfall is found to be greater than 230cm per year and temperature may range from 25-29°C. In tropical deciduous forests, temperatures may range from 25-39°C and rainfall is found to be 130-280 cm. per year.

In temperate rainforests, the temperature on average ranges from 5-25°C, and rainfall is 200 cm per year. In temperate deciduous forests, the temperature is 12°C and rainfall may range from 75-200 cm per year.

Therefore, abiotic factors like temperature, precipitation (rainfall), and the intensity of wind are primarily responsible for distinguishing different biomes.

What is plasma membrane?

The membrane that basically divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and it is present in all cells.

The cell membrane isolates a cell's interior contents from its external environment, just like your skin's outer layer does for your body and its surroundings.

The cell membrane acts as a barrier to protect it and controls what can enter and leave the cell.

One of the body's first lines of defense against hazardous germs is the skin, which acts as a barrier. Skin tissue contains specialized immune cells that aid in the defense against invaders.

The skin, however, is home to a variety of communities of helpful bacteria known as the skin microbiota.

Thus, the correct option is C.
