To solve the problem, we can use the ideal gas law and the mole ratio of the balanced chemical equation to determine the partial pressures of the gases at equilibrium, and then add them to obtain the total pressure.

First, we need to calculate the number of moles of each reactant:

n(H2) = 5.966 g / (2.016 g/mol) = 2.965 mol

n(C) = 22.44 g / (12.01 g/mol) = 1.869 mol

According to the balanced equation, the mole ratio of H2 to CH4 is 2:1. Therefore, the number of moles of CH4 produced at equilibrium is:

n(CH4) = n(H2) / 2 = 1.483 mol

Next, we can use the ideal gas law to calculate the partial pressures of the gases at equilibrium:

PV = nRT

For H2:

n = 2.965 mol

R = 0.0821 L·atm/(mol·K)

T = 1000 K

V = 9.75 L

P(H2) = nRT/V = 7.74 atm

For CH4:

n = 1.483 mol

R = 0.0821 L·atm/(mol·K)

T = 1000 K

V = 9.75 L

P(CH4) = nRT/V = 3.85 atm

Therefore, the total pressure at equilibrium is:

total = P(H2) + P(CH4) = 7.74 atm + 3.85 atm = 11.59 atm

For the second part of the question, we repeat the same process, but with a different amount of carbon:

n(H2) = 5.966 g / (2.016 g/mol) = 2.965 mol

n(C) = 8.006 g / (12.01 g/mol) = 0.666 mol

The mole ratio of H2 to CH4 is still 2:1, so the number of moles of CH4 produced at equilibrium is:

n(CH4) = n(H2) / 2 = 1.483 mol

Using the ideal gas law, we can calculate the partial pressures of the gases at equilibrium:

For H2:

n = 2.965 mol

R = 0.0821 L·atm/(mol·K)

T = 1000 K

V = 9.75 L

P(H2) = nRT/V = 7.74 atm

For CH4:

n = 1.483 mol

R = 0.0821 L·atm/(mol·K)

T = 1000 K

V = 9.75 L

P(CH4) = nRT/V = 3.85 atm

Therefore, the total pressure at equilibrium is:

total = P(H2) + P(CH4) = 7.74 atm + 3.85 atm = 11.59 atm

Note that the total pressure is the same as in the first part of the question, despite the different amount of carbon used. This is because the mole ratio of H2 to CH4 and the temperature are the same in both cases.

The calculated wolf population size in 2017 based on the data claimed by the student claim is 173, option D is correct.

Based on the student's claim, the carrying capacity of wolves in Yellowstone National Park has been 100 wolves since 2007, and the maximum annual per capita growth rate of gray wolves is 0.6 wolves per wolf per year. To calculate the wolf population size in 2017, we can use the formula for exponential population growth:

Population size = Initial population size × (1 + growth rate)^(number of years)

Using this formula, we can calculate the population size in 2017 based on the given data. Starting with an initial population size of 108 wolves in 2016, and assuming a constant maximum annual per capita growth rate of 0.6, we can calculate the population size in 2017 as follows:

Population size in 2017 = 108 × (1 + 0.6)⁽²⁰¹⁷ ⁻ ²⁰¹⁶⁾

= 108 × 1.6¹

Answer:

The given statement is false.

Explanation:

Irrespective of being broad sensed or narrow sensed, heritability demonstrates a prediction of variation in the phenotypic trait in the organism's population, which has originated due to genetic variation between the individuals within the population. Apart from determining phenotypic variation because of genetic variation, it also determines the origination of the phenotypic variations because of the elements other than random chance or environment. Heritability holds for the origination of the changes taking place due to non-genetic factors as well.

When one talks about the changes taking place due to additive factors or the factors other than genetic factors it comes under narrow-sense heritability, while the broad sense heritability majorly deals with genetic factors. Thus, based on the given statement, the narrow-sense heritability cannot be considered as zero for the phenotypic variations originating because of other genetic variations.

The genetical variance refers to the concept of natural selection. It states a change in biological fitness is calculated by the variance from the fitness itself.

The generation time of the bacteria in the following culture is approximately 3.01  hours.

To determine the generation time of bacteria, we can use the formula:

Generation time (t) = (Time elapsed (T) / Number of generations (n))

In this case, we have a time difference of 10 hours between the two samples.

To calculate the number of generations, we can use the formula:

Number of generations (n) = log(N₂ / N₁) / log(2)

Where N₂ is the final cell count (10,000 cells/ml) and N₁ is the initial cell count (1,000 cells/ml).

Plugging in the values, we get:

Number of generations (n) = log(10,000 / 1,000) / log(2) ≈ 3.32

Now, we can calculate the generation time:

Generation time (t) = Time elapsed (T) / Number of generations (n)

Generation time (t) = 10 hours / 3.32 ≈ 3.01 hours

Therefore, the generation time of the bacteria in this culture is approximately 3.01 hours.

Advantages Of the asexual reproduction

The organism that reproduces asexually has the ability to take many different extensive forms that allow asexual reproduction to succeed in various environments?

The asexual reproduction is only performed in the organisms that often stay in one place, It does not need mobility, So, most plants have a great ability to create their offspring as this process doesn’t need to move to another place.

Asexual reproduction has a rapid increase of offspring which is very helpful in producing lots of offspring, It lets the plants make lots of offspring effectively which will help them in increasing their genes.

Disadvantages Of Asexual Reproduction

Most organisms that only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments.

Only one parent plant is required for the asexual reproduction, the new plants are identical to the parent so that good features will always be passed on, the chromosomes and genes of the parent will be copied, So, there will be genetic defects or the mutation in the offspring with no exception.

The asexual reproduction does not have the genetic diversity, there is less variation produced with the offspring, and the organism becomes less adapted to certain environmental changes, the entire communities will not be adapted to the harsh environment.

The asexual reproduction usually leads to struggle for the existence as well as the overcrowding, and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce.

The objective of ensuring "finance flows commensurate with a route towards low greenhouse gas emissions and climate-resilient development" is stated in Article 2.1(c) of the Paris Agreement. This ambition extends much beyond the typical focus of climate financing on assisting impoverished nations.

For example, Ghana's total greenhouse gas emissions in 2019 were 58.56 MtCO2e (million tonnes of carbon dioxide equivalent), 16% more than in 2016. Because of this continued rise in Greenhouse emissions as well as the existence of harmful chemicals in their cocoa, Europe recently indicated that they'd be cutting back on how much import they off-take from Ghana.
