In the chamber, we turn the carbon dioxide valve all the way up. in chamber b we only provide half as much carbon dioxide as the first chamber plants.
Carbon dioxide is an odorless, colorless fuel. it's miles a waste product that your body makes whilst it makes use of food for energy. Your blood consists of carbon dioxide in your lungs. when you exhale, you breathe out carbon dioxide. Having too much or too little carbon dioxide in your blood can be a signal of a health problem.
Natural resources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that cause carbon dioxide emissions come primarily from energy production, along with burning coal, oil, or natural fuel.
Hypercapnia, or hypercarbia, is when you have an excessive amount of carbon dioxide (CO2) in your bloodstream. It generally occurs because of hypoventilation or no longer being able to breathe properly and get oxygen into your lungs.

during translation in prokaryotes formation of the initiation complex does not require RNA polymerase.
what is translation in prokaryotes ?In prokaryotes nucleus is absent, so transcription and translation occur simultaneously in the cytoplasm, where these two processes are coupled
Due to this coupling process prokaryotes produce proteins more efficiently, and faster in situations of need like during DNA replication or when it faces an environmental challenge.
This is different than gene expression in eukaryotic cell where transcription occurs in a membrane-enclosed nucleus together with processing of mRNA and transported to the cytoplasm.

Linked genes are always syntenic, and they are always located near or one another on a chromosome. When syntenic genes are so far apart on the chromosome that crossing over between them generates independent assortment of the alleles, the genes are not linked.
2) Genetic linkage leads to the production of a significantly greater number of gametes containing chromosomes with parental combinations of alleles than would be expected under assumptions of independent assortment and to a significantly smaller number of gametes containing chromosomes with alleles that are different from the parental combinations.
3) Crossing over is less likely to occur between linked genes that are close to one another than between genes that are farther apart on a chromosome.
Genetic Linkage observations
A potent method for identifying the chromosomal location for disease genes is genetic linkage analysis.Genes that are located physically close to one another on a chromosome continue to be connected.
By calculating the recombination frequency using information from genetic crosses, we may determine if and how closely two genes are connected. Making linkage maps, which display the arrangement and relative locations of the genes just on chromosome, requires finding the recombination frequencies for several gene pairs. On the same chromosome, linked genes are those that are situated adjacent to one another. They are typically inherited jointly (but not always). One lengthy strand of DNA, one chromosome, codes to hundreds or even thousands of distinct genes. Each gene does have a particular spot on each chromosome known as a locus. In terms of genetics and genomics, linkage describes how closely genes or even other DNA sequences are located to each other on the identical chromosome.

The moment that they enter the human body, vegetative cells sporulate. This claim is untrue. The developing cell, also known as a vegetative cell, forgoes typical cellular division to create an endospore during sporulation.
Some bacteria, primarily Firmicutes, will sporulate as a dramatic reaction to intense stress. When the environment is favorable for bacterial growth and reproduction, endospores re-grow into vegetative cells, active bacterial cell that engages in metabolism. It transforms from vegetative cells into endospores in hazardous environments if they can. Endospores are subsequently created inside the vegetative cell as a result, and these cells lyse to release the endospores.
Thus, we can conclude that when vegetative cells reach the human body, they do not sporulate.

Determine which statement about pedigrees is accurate.
Pedigrees show how a trait is inherited throughout several generations.
Pedigrees show a trait passed only from parent to the first set of offspring.
Pedigrees are only use by doctors to track sicknesses
Answer:
Pedigrees show how a trait is inherited throughout several generations.
Explanation:
We can eliminate the second answer choice because pedigrees show a trait passed through multiple generations, not just a trait passed from parents to the first set of offspring: the purpose of a pedigree is to see the pattern of how the trait passes, so there needs to be more than a generation of just parents and the first set of offspring. The third statement can also be eliminated because the trait being tracked might not always be one that leads to sickness. This leaves the first statement, which is correct.

A tropic hormone is any hormone that stimulates or suppresses the release of other hormones.
What is tropic hormone?Tropic hormones are hormones of the anterior pituitary gland. These hormones influence the growth, function, or nutrition of other endocrine cells.Tropic hormones are found in body systems including the endocrine, gastrointestinal, urinary, and nervous systems.Tropic hormones are released from one endocrine gland and act on another. Tropic hormones stimulates the growth of target tissues. They can lead to hypertrophy or hyperplasia. Most tropic hormones are produced and secreted by the anterior pituitary gland. The hypothalamus secretes trophic hormones that target the anterior pituitary gland, and the thyroid secretes thyroxine, which targets the hypothalamus, and thus can be considered trophic hormones. Tropic hormones act indirectly on target cells by first stimulates other endocrine glands.

when a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because:
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
The manner of breakdown of the glucose molecule into pyruvic acid is called glycolysis. The manner of glycolysis is accomplished below the cardio response. The response which occurred in presence of air is called cardio response.
In this manner, Glucose is absolutely digested into carbon dioxide, water, and energy. Hence, the lactic acid is not shaped.
The lactic acid is shaped because of a scarcity of oxygen and leads to incomplete oxidation.
Hence, the correct is E that is below cardio conditions maximum of the pyruvate generated because of glycolysis is oxidized through the citric acid cycle as opposed to decreased to lactate.
Complete question is
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because:_____________. 1. glycolysis does not occur to significant extent under aerobic conditions. 2. muscle is metabolically less active under aerobic than anaerobic conditions. 3. the lactic acid generated is rapidly incorporated into lipids under aerobic conditions. 4. under aerobic conditions in muscle, the major energy-yielding pathway is the pentose phosphate pathway, which does not produce lactate. 5. under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
