in ____, one allele is dominant to a recessive allele.
In Simple Dominance, one allele is dominant to a recessive allele.
Simple dominance occurs when a single gene codes for both the dominant allele and the recessive allele of an inherited characteristic. The dominant allele of the gene masks the recessive allele.
what is dominant and recessive allele?
The relation between different genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be displayed.
For instance, because the dominant gene for brown eyes only needs one copy of the 'brown eye' allele to result in brown eyes (although, with two copies you will still have brown eyes).
Recessive alleles are a subset of alleles that do not affect a person when they are present alone.
For instance, you need two copies of the "blue eye" allele because it is recessive in order to have blue eyes.
Therefore, in Simple Dominance, one allele is dominant to a recessive allele.

"Nitrogen fixation results in the while the metabolic process of denitrification
A. loss of biologically available N from an ecosystem / oxidizes N2.
B. formation of nitrogen gas / oxidizes NO:
C. direct formation of nitrate / reduces N2.
D. addition of biologically available N to an ecosystem / reduces NO. "
Nitrogen fixation results in the addition of biologically available N to an ecosystem while the metabolic process of denitrification reduces NO.
What is the process of denitrification?The denitrification procedure removes bioavailable nitrogen from the environment by converting nitrate to nitrogen gas.
Although nitrogen gas (N₂) is the final byproduct of denitrification, there are also additional intermediate gaseous forms of nitrogen. Nitrous oxide (N₂O), one of these gases, interacts with ozone to form greenhouse gases that cause ozone depletion and air pollution.
Denitrification and other anaerobic processes often occur in an anoxic lake and sea bottom areas, sediments, and soils. There are many different types of prokaryotes that can denitrify, and recent research has shown that some eukaryotes can as well. Bacillus, Paracoccus, and Pseudomonas species are some of the denitrifying microorganisms.
2 NO₃⁻ + 10 e⁻ + 12 H⁺ → N₂ + 6 H₂O.

What do "tolerance" and
"quality" have in common?
Tolerance limits are boundaries that enclose a certain percentage of a population with a certain level of confidence.
Used in the context of process control to ensure that production does not go out of specification. Using tolerances can make the final product easier to use, especially if it is part of a larger assembly. Any manufacturing method introduces some degree of inaccuracy, and failure to meet tolerances in critical areas can result in a part that cannot be used according to design intent.
Tolerance determines exactly how much is allowed in making each part. Understanding the critical role tolerances play in the manufacturing process can help you design higher-quality products and reduce costly manufacturing errors. Tolerance design plays an important role in product life cycle quality. Its purpose is not only to guarantee product quality. At the same time monitor the manufacturing costs of your products.

In order for digestion to occur, chyme is required to contact the microvilli of the intestinal wall because the __________.
Chyme is required to contact the microvilli of the intestinal wall because the brush border enzymes are not secreted into the lumen.
What is chyme?A chyme is a semi-liquid mass of partially digested food that is expelled from a person's stomach through the pyloric valve into the duodenum. Chyme is formed by mechanical and chemical breakdown of the bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes.
Chyme has two main functions: first, it increases the surface area of food so that digestive enzymes can work, and second, it stimulates various digestive glands to produce secretions. The action of the enzyme requires direct contact with the substrate molecule.
When food enters the stomach, stomach muscles mix the food and liquid with digestive juices. The stomach slowly expels its contents, called chyme, into the small intestine.

Which factor is the most powerful evolutionary force in large populations over time?.
The most powerful evolutionary force in large populations over time is natural selection.
Natural selection is the process by which certain traits become more common in a population over time because those traits help the individuals with those traits to survive and reproduce.
For example, if a population of animals is exposed to a new predator, the individuals that are able to run the fastest will be more likely to survive and reproduce, and over time the population will become faster on average.Over time, this process can lead to the emergence of new species and with these advantageous traits they are more likely to survive.

Starches and sugars are mechanically and chemically broken down into the single units glucose, fructose, and/or galactose during digestion. These single units are then absorbed into the blood stream and transported to be used as energy throughout the body.
What is carbohydrate metabolism?The entire set of biochemical procedures involved in the metabolic synthesis, disintegration, and interconversion of carbs in living things is known as carbohydrate metabolism. Many vital metabolic pathways depend on carbohydrates.
Dietary glucose can either be processed through glycolysis or glycogenesis.
The resulting metabolic byproducts can either go on in carbohydrate metabolism to the citric acid cycle or return to glucose via gluconeogenesis or glycogenolysis, respectively.
Carbohydrates are broken down during digestion to produce ATP, a molecule that is high in energy.
The oxidation of glucose molecules results in the creation of ATP. To lower NAD+ and FAD, an electron is taken from a glucose molecule during oxidation.

what biogas generator tend to work best in hot countries
The United States generates over 70 million tons of organic waste each year. Biogas is produced after the decomposition of organic matter by bacteria in an oxygen-free environment. This is a process called anaerobic digestion.
Biogas systems use anaerobic digestion to recycle these organics and convert them into biogas which contains both energy and valuable bottom products. Stored biogas can provide a clean, renewable and reliable baseload power alternative to coal and natural gas. Baseload power is generated continuously to cover minimum power demand. Baseload renewables can supplement more intermittent renewables.
Like natural gas, biogas can also be used as a rapidly capable peak power source. Direct use of biogas has the highest efficiency, but the use of this fuel is usually confined to locations close to the anaerobic digester, limiting available markets and applications. Biogas is a methane-rich gas obtained from the anaerobic digestion of organic matter.
