Ethanol for Transport Part 2 0.0/5.0 puntos (calificado) Ethanol has an energy density of .021 GJ/L. How many liters of ethanol are required to supply US transportation demand? Liters Enviar Consejo Guardar Ha realizado 0 de 5 intentos Reiniciar
Ethanol are required to supply US transportation demand is approximately 1.41 trillion liters.
To determine how many liters of ethanol are required to supply US transportation demand, we need to know the total energy demand for transportation in the US. According to the US Energy Information Administration (EIA), the total energy consumption for transportation in the US in 2019 was 28.1 quadrillion British thermal units (Btu).
To convert Btu to GJ, we need to multiply by 1.055. Therefore, the total energy consumption for transportation in the US in 2019 was 29.6 quadrillion GJ. To determine the volume of ethanol required to supply this demand, we can use the following formula:
Volume of ethanol = Total energy demand / Energy density of ethanol
Substituting the values we have, we get:
Volume of ethanol = 29.6 quadrillion GJ / 0.021 GJ/L
Volume of ethanol = 1.41 trillion liters
Therefore, approximately 1.41 trillion liters of ethanol would be required to supply US transportation demand based on the given energy density of ethanol. It's worth noting that this calculation assumes that ethanol would be the only fuel source for transportation in the US, which is not currently the case.

Compute the age of a basalt rock sample from the Moon containing 6 grams of Uranium-235 (parent isotope) and 42 grams of Lead-207 (daughter isotope). This rock is from a complex crater flooded with lava. The half-life of Uranium-235 is 704 million years.
Answer:
Age of rock = 21112000000 years
Explanation:
The half-life of a radioactive material is the time taken for half the original material to decay or it is the time required for a quantity to reduce to half of its initial value.
The ratio of parent isotope, Uranium-235 to daughter isotope, Lead-207 = 6 : 42 = 1 : 7
This means that for every one gram of the parent isotope, there are 7 grams of the daughter isotope. So,the quantity of radioactive material left is one out of eight its original value.
Number of half-lives undergone for 1/8 of the original value to to remain is given below:
1/8 = 1/2 × 1/2 × 1/2
Therefore, number of half-lives = 3 half-lives
Age of rock = half-life of Uranium -235 × number of half-lives
The half-life of Uranium-235 is 704 million years = 704000000
Age of rock = 704000000 × 3
Age of rock = 21112000000 years

A. increase the reproductive rate in successive generations
B. decrease in frequency in successive generations
C. appear at the same frequency in successive generations
D. undergo a series of mutations in successive generations
A trait that does not offer members of a population a great advantage will most likely decrease in frequency in successive generations. Thus, option B is correct.
What is theory of natural selection?
According to Charles Darwin in his theory of natural selection, organisms must compete for scarce resources. Only the fittest can survive. The fittest are organisms that have undergone the required genetic changes that increases their chances of survival. They pass on these genetic changes to the next generation or offspring.
When availability of food decreases, organisms begin to change genetically as they struggle for scarce resources thereby leading to variation in a population. All organisms must compete for survival. Natural selection continues to occur even today.When organisms struggle to survive, they usually mutate to increase chances of reproduction.

drag the correct numbers into position to show mrs. h what will happen to her if she breathes half as deeply but twice as often.
Mrs. H's respiratory rate will increase and the oxygen concentration in her blood will decrease if she breathes half as deeply but twice as often. This will lead to respiratory distress and may even result in fainting.
Breathing is the exchange of air between the atmosphere and the lungs. This process is critical since it allows the body to take in oxygen and get rid of carbon dioxide. The respiratory rate is the number of breaths taken in a minute. It can be affected by various factors such as exercise, anxiety, and illness. The volume of air inhaled and exhaled during each breath is known as respiratory ratevolume. When Mrs. H breathes half as deeply but twice as often, her respiratory rate will increase, while the tidal volume will decrease. This leads to respiratory distress since the oxygen concentration in her blood will decrease. As a result, the body may respond by hyperventilating, which can cause fainting if prolonged.

true or false phosphatese remove the phosphate from gtp on gtp binding proteins
The statement that phosphatases remove the phosphate from GTP on GTP binding proteins is a false statement.
What are GTP-binding proteins?
GTP-binding proteins are a family of membrane-associated proteins that play a critical role in signal transduction. The family of GTP-binding proteins is divided into three subfamilies: (i) monomeric GTPases, (ii) heterotrimeric G proteins, and (iii) dynamin.
How do GTPases work?
GTPases act as molecular switches that are turned on by exchanging GDP (guanosine diphosphate) for GTP (guanosine triphosphate). The activation of GTPase results in the binding of GTP to the protein, leading to a conformational change that enables it to interact with downstream effectors, resulting in a specific cellular response.
The GTPase cycle ends with the hydrolysis of GTP to GDP, which is facilitated by GTPase activating proteins (GAPs). This converts the GTPase back to its inactive form, allowing the protein to be used in another signaling event.
The removal of phosphate from GTP on GTP-binding proteins is accomplished by GTPase-activating proteins (GAPs). This is not performed by phosphatases. As a result, the given statement is false.

If flower color and flower size are controlled by a single gene each, what can be concluded from these results? a. Flower color is controlled by a sex-linked gene. b. Red color and small size are dominant to white color and large size, respectively. c. Small size is dominant to large size, but we can't determine which color is dominant. d. We can't determine which color and which size are dominant. e. White color and small size are dominant to red color and large size.
From the given results, it can be concluded that red color and small size are dominant to white color and large size, respectively.
The F1 generation consists of 75 plants with small red flowers and 72 plants with small white flowers. This indicates that the traits for flower color and flower size segregate independently and are controlled by different genes. Since there is a presence of both red and white flowers in the F1 generation, with red being the dominant color, it can be inferred that red color is dominant over white color.
Similarly, since there is a presence of both small and large flowers in the F1 generation, with small being the dominant size, it can be concluded that small size is dominant over large size. Therefore, the correct answer is b. Red color and small size are dominant to white color and large size, respectively.

Today, around 42 percent of global electricity production is based on coal. Two major impacts from extracting and burning coal are: Burning coal produces noxious fumes that pollute the skies and contribute to climate change. Coal mining often involves environmental disruption as land is poked and prodded, vegetation is destroyed, and waste material pollutes the soil and water. Both A and B are two major impacts from extracting and burning coal.
Explanation: Coal is a combustible black or brownish-black sedimentary rock, and the world's most plentiful fossil fuel. Coal is made up of carbon, hydrogen, and oxygen, as well as smaller amounts of sulphur and other elements. The carbon in coal, when burned, produces energy in the form of heat and light.
Today, around 42 percent of global electricity production is based on coal. There are two major impacts from extracting and burning coal which are discussed below: A. Burning coal produces noxious fumes that pollute the skies and contribute to climate change. Burning coal emits noxious fumes that contribute to air pollution and climate change. Nitrogen oxide (NOx), sulfur dioxide (SO2), and particulate matter (PM) are some of the dangerous pollutants produced by coal combustion. The sulfur dioxide and nitrogen oxide released by coal combustion can cause acid rain, which has harmful effects on plants, soils, and bodies of water. Burning coal is also a significant contributor to greenhouse gas emissions, accounting for around one-third of total energy-related carbon dioxide emissions worldwide B. Coal mining often involves environmental disruption as land is poked and prodded, vegetation is destroyed, and waste material pollutes the soil and water. Extracting coal from the earth is a harmful process that causes environmental damage.
Coal mining can result in the loss of habitats for animals and plants, as well as the contamination of nearby soil and water sources. Acid mine drainage (AMD) is a typical problem associated with coal mining. AMD is a toxic byproduct of coal mining that contaminates water and kills fish, insects, and other aquatic life. Coal mining also degrades the quality of the surrounding landscape, which can have significant environmental and economic effects.

No, disruptive selection does not always have to be happening for speciation to occur.
Speciation refers to the formation of new species, which involves the evolution of reproductive isolation between populations.
While disruptive selection can contribute to speciation, there are other mechanisms that can also lead to the formation of new species.
Disruptive selection occurs when natural selection favors extreme phenotypes over intermediate phenotypes, leading to a divergence in the population.
