39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32
What is a Balanced chemical equation?A balanced chemical equation has the same number of reactants and products. We can balance a chemical equation by adding a number to adding the same number of molecules on both sides.
In this equation,
10NO3 + 10 e - -> 5N2
4H + 2 e - -> 2H2
In this equation, 5 moles of N2 and 2 moles of Hydrogen are produced.
5 * 0.74 = 3.7 V
2 * ( -0.42) = - 0.84 V
ΔG = -nFΔE,
where F = 96.48 kJ (mol e-)
= 90 * 96.48 * (3.7 + 0.84)
= 90* 96.48* 4.54
= 39462 KJ
Therefore, 39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32.

Which process has most likely occurred when new traits appear in a species?
O
selective breeding
genetic mutation
crossbreeding
O cloning
Heritable variations (genetic variation) between organisms are caused by new or altered features that are produced as a result of gene mutations.
Describe heredity.
The total of all biological processes through which certain traits are passed from one set of parents to the next is known as heredity.
When heritable differences in a population increase in frequency, either non-randomly through natural selection or randomly through genetic drift, evolution has taken place.
The genetic heritage which our biological parents have left behind is knowns to as heredity. That's why we resemble them. In deeper, it refers to the passing down of traits from one generation to the other. These characteristics can be behavioral or physical, such as eye color, blood type, or an illness. For instance, honeybees' hygienic behavior, which motivates them to remove unhealthy larvae from the nest, is a hereditary trait.

Chemistry support Agricultural sciences by helping develop pesticides and fertilizers.
Agricultural sciences, which deal with the processing and production of food and fiber. They cover techniques for cultivating soil, growing and harvesting crops, raising animals, and preparing plant and animal products for use and consumption by humans.
Food is a human being's fundamental necessity. Only agriculture is able to provide this need for the entire world's population. Plants are referred to as producers because they use CO2 from the air and water from the soil to create their own food through a process known as photosynthesis, which also uses sunlight as an energy source. The only other members of the food chain are consumers. Agriculture is the activity of raising crops and cattle using the earth's natural resources. Agronomy, horticulture, animal husbandry, dairying, soil chemistry, and other fields of modern agriculture are included.
Agriculture deals with the generation of organic goods using both organic and inorganic inputs, whereas chemistry works with molecules, both organic and inorganic. Thus, from the molecular to the organ level, chemistry is a fundamental component of agriculture. It has an impact on everything from the fundamentals of photosynthesis to how agricultural products are used. The improvements in this method are solely attributable to chemistry research that is currently being done and applied to make the land produce more abundantly while also protecting it from abuse and deterioration.

All individuals will have the dominant phenotype
25% will have the dominant phenotype, and 75% will have the recessive phenotype.
When purebred or homozygous individuals that differ in a particular trait are mated, all offspring will be heterozygous for that trait. If the trait is inherited as dominant and recessive, all F1 offspring exhibit the same phenotype as the parent homozygous for the dominant trait. Monohybrid matings have a dominant to recessive phenotype ratio of 3:1.
In complete dominance, there is no phenotypic difference between AA and Aa individuals. In imperfect dominance, the phenotype of heterozygous individuals is clearly less intense than that of homozygous individuals for the dominant allele, such that the AA and Aa genotypes produce different phenotypes.

A diagram of the solar system shows the sun in the middle. Why does every other object orbit around the sun?
• The sun is smaller than other objects in the solar system.
O The sun is an average size for a star.
O The sun is so bright.
O The sun is the most massive object in the solar system.
Every other object revolves around the Sun because the Sun is the most massive object in the Solar System. Therefore, the correct option is D.
The Sun's powerful gravitational pull causes every other object in the Solar System to revolve around it. The force that controls how celestial bodies move through space is called gravity. All the planets, moons, asteroids and comets in the Solar System are under the strong gravitational pull of the Sun due to their enormous mass.
As a result these objects are constantly pulled towards the Sun, due to which they revolve around it. As we know, the Solar System was formed by the interaction of the gravitational force of the Sun and the forward motion of these bodies, which keeps them in stable orbits.
Therefore, the correct option is D.

The top three organelles are______, ______ and _______ because they do _____________, ___________ and ___________
In a cell there are mainly 6 organelles: nucleus, mitochondria, chloroplasts, golgi apparatus, endoplasmic reticulum and ribosomes.
Out of these the top 3 cell organelles are nucleus, mitochondria and golgi apparatus because they are the source of all other cell components and they have crucial functions:
Nucleus: The storage of the DNA or the inherited material of the cell is one of the nucleus' two main jobs. It is in charge of organizing a variety of crucial cellular processes, including protein synthesis, cell division, growth, and a number of other crucial operations.
Golgi apparatus: Proteins obtained from the ER are further processed and sorted in the Golgi apparatus, or Golgi complex, where they are eventually transported to lysosomes, the plasma membrane, or secretion. As was already mentioned, the Golgi also produces sphingomyelin and glycolipids.
Mitochondria: The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria.

Describe saturation as characteristics of mediated transport mechanism
The three types of carrier-mediated transport are present facilitated diffusion, primary active transport, and secondary active transport which involve integral membrane proteins. Three characteristics are present in all kinds of carrier-mediated transport: saturation, stereospecificity, and competition.
The saturation is defined as the saturability of the carrier proteins which only have a finite number of solute binding sites.
Many binding sites be accessible at lower solute concentration concentrations, and as the concentration rises, so does the rate of transport. However, the number of accessible binding sites decreases and the rate of transport plateaus at high solute concentrations. Finally, saturation is attained at a point known as that of the transport maximum, or Tm, at which all of the binding are occupied.

The conditioned stimulus is the decision that you took. You made the decision that you won't be having the same food again based on the fact that you got sick by eating there. This is a conditioned stimulus.
Weeks later, you cringe at the smell of ham. This is an unconditioned response, because it is an automatic response or a response that occurs without thought when an unconditioned stimulus is present.
