What physical feature of the human eye lends imporant support to the trichromatic therory of color vision?
The various types of cones in the retina is physical feature of the human eye lens is important to support the trichromatic theory of color vision.
What is trichromatic theory?Trichromatic refers to something with three colors because the prefix "tri" implies three and the root "chroma" means color.According to the trichromatic hypothesis of color vision, the retina contains three distinct color receptors. The retina's cones are responsible for providing color vision.According to this view, the cones are sensitive to the hues of green, blue, and red. Eyes can distinguish between millions of different colors when these colors are blended.Thomas Young and Hermann von Helmholtz were the ones who first put out this notion. Thomas Young was the first to postulate the existence of three color receptors in human eyes, each of which is sensitive to a different range of light wavelengths: short, medium, and long.Hermann von Helmholtz conducted a number of experiments to test the hypothesis decades later and discovered it to be accurate.The Young Helmholtz Trichromatic Theory is hence another name for the theory.Learn more about trichromatic theory here

In the DNA isolation process, ice cold 95% ethanol is used to break down the protein complexes and allow the DNA molecules to easily precipitate.
What is separation and isolation of DNA fragments?
The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis. Since, DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix. The most commonly used matrix is agarose which is a natural polymer extracted from sea weeds. The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). We can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light. The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution. The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with cloning vectors.To learn more about DNA isolation process: https://brainly.com/question/18316109

An organism’s complexity ____ with the number of its genes; it ____ with the amount of junk dna.
An organism's complexity is directly related to the amount of junk DNA.
Most eukaryotic genomes are larger and more complex than those of prokaryotes. However, the genome size of many eukaryotes does not appear to be related to genetic complexity.
For example, the genomes of salamanders and lilies contain more than ten times the amount of DNA that is in the human genome, yet these organisms are clearly not ten times more complex than humans.
Further studies showed that in the human genome only 2.5%of the genes are coding for protein while the rest of the 97.5% of genes are non-coding genes or junk DNA.

performing a endospore stain on a gram-positive bacteria and that is not endospore forming. at the end of the stain it will look pink due to absence of any endospores.
Some bacteria create bacterial endospores, extremely resistant, metabolically dormant entities as a defense mechanism against unfavorable environmental conditions. Until conditions are right, the bacteria can stay in this suspended state and eventually germinate and go back to their vegetative state.By heating the bacterial emulsion, the Schaeffer-approach Fulton's forces a primary stain, malachite green, into the spore. Vegetative cells may be decolored with water since malachite green is water soluble and has a poor affinity for cellular matter. After that, safranin is used to counterstain any decolored cells.

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.
Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.
In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).

Calcium that enters the cell during smooth muscle excitation binds with calmodulin.
What is calmodulin?All eukaryotic cells express calmodulin, a multifunctional intermediate messenger protein that binds calcium. Calmodulin is an intracellular target of the secondary messenger Ca2+, and Ca2+ binding is necessary for calmodulin activation.Various calcium-sensitive enzymes, ion channels, and other proteins get signals from calmodulin, a protein that functions as an intermediate protein that senses calcium levels. All eukaryotic cells have the calcium-binding protein calmodulin, also known as calcium-modulated protein, in their cytoplasm. It interacts with a large number of other proteins in the cell and performs a wide range of biological tasks as a regulator or effector molecule.Calmodulin binds calcium and magnesium. Different calcium-calmodulin complexes then bind to and activate enzymes that control cellular calcium or cyclic nucleotides as well as particular protein kinases that control target enzymes by ATP-dependent phosphorylation.

a. bacteria
b. plants
c. most insects
d. mammals
Option (A) Bacteria is the correct answer.
The coding sequence in the DNA of bacteria is normally continuous; that is, it is not interrupted by non-coding sequences.
How are coding sequences in the DNA of bacteria?The segments in the genome known as non-coding sequences don't encode for any proteins or amino acids.
These sequences either have structurally significant functions in telomeres or satellite DNA, play functional roles in controlling gene expression, or are intervening sequences known as introns.
Although bacteria have non-coding DNA sequences, they are quite a few in comparison to eukaryotic cells.
Non-coding sections make up only 12 percent of the bacterial genome, as opposed to 98 percent in eukaryotes.
The great majority of known bacterial ncRNAs are encoded from intergenic regions, where, like protein-coding genes, their production is regulated by promoter and terminator elements.
Therefore, the coding sequence in the DNA of bacteria is normally continuous; that is, it is not interrupted by non-coding sequences.

The muscles on the right side of Omar's body were smaller than those on the left side due to Hemihypertrophy.
A hereditary condition known as hemihypertrophy causes a person's body to expand excessively on one side compared to the other. Because of continuing bone or soft tissue growth, one side of the body grows more quickly than the other. Everyone who is affected can have a different appearance, and youngsters frequently have it. One area of the body, like the legs, may be unaffected by the overgrowth. However, it might also affect the mouth, face, and limbs, among other body parts. Although the gene that causes hemihypertrophy isn't always known, it can be passed on from parents to children.
