a triplet of bases in a template strand of dna is gat. what would be the corresponding codon for mrna?
The corresponding codon for mRNA is CTU.
The template strand is the strand of DNA from which mRNA is synthesized. The coding or non-template strand is the DNA strand that is complementary to the template strand. It has the same sequence as mRNA. The DNA strand that serves as the template for RNA has the base sequence AGCTTCGA. Although DNA is double-stranded, only one strand at a time serves as the template for transcription.
This template strand is called the non-coding strand. The non-template strand is called the coding strand because its sequence is the same as that of the new RNA molecule. mRNA is normally translated by a series of ribosomes about 100 to 200 nucleotides apart. A group of ribosomes attached to an mRNA molecule is called polyribosomes or polysomes. Each ribosome within a group functions independently to synthesize a separate polypeptide chain.

the folowing statements are true about fermentation: a. all of the above are true b. net two molecules of atp are produced c. takes place in prokaryotes and eukaryotes. d. does not require o2.
All of the above statements are true about fermentation. In fermentation, net two molecules of ATP are produced. This process takes place in both prokaryotes and eukaryotes. However, fermentation does not require oxygen.It is an anaerobic process.
Fermentation is a metabolic process that produces ATP through the breakdown of glucose. This process does not require oxygen and takes place in the absence of oxygen. In fermentation, glucose is converted into pyruvate, and then pyruvate is converted into ATP. The net production of two ATP molecules per glucose molecule is lower than that of aerobic respiration, but fermentation does not require oxygen, making it an important process in anaerobic conditions.
Fermentation is used by many organisms, including bacteria, yeast, and some plants. In bacteria, fermentation is used to produce lactic acid, which is then converted into ATP. In yeast, fermentation is used to produce ethanol and carbon dioxide. In plants, fermentation is used to produce lactic acid, ethanol, and carbon dioxide.
Fermentation is an important process in the food industry. It is used to produce bread, wine, beer, and cheese. It is also used to produce yogurt, sauerkraut, and other fermented foods.

The body's estimated total number of billions of capillaries is seven, based on the equation of continuity is 7×[tex]10^{9}[/tex].
The blood's density is relatively constant from the aorta to the capillaries. The volume flow rate across all capillaries must be equal to the volume flow rate in the aorta according to the continuity equation.
The area of a sample capillary is multiplied by the overall number of capillaries N to get the total area of all of the capillaries.
Assume that A1 represents the aorta and that A2 represents all of the blood vessels.
Then A1 = N× π×r²
where r = 4 x [tex]10^{4}[/tex] cm is thought to be the capillary's average radius. We can infer from the continuity equation that
v2×A2 = v1×A1
v2×π×N×r²cap = v1×π×r²arota

The first step in the proton-proton chain produces an antielectron, or positron. What happens to the positron?.
An antielectron, or positron, is created in the proton-proton chain's first phase. When it collides with an ordinary electron, it quickly transforms into energy, causing matter-antimatter annihilation.
The opposite of an electron is a proton. The primary distinction between them and electrons is their positive charge. Positrons are created during the decay of nuclides that have more protons than neutrons in their nucleus. These radionuclides release a neutrino and a positron when they decay.
With the exception of having the opposite charge and spin, antimatter particles are almost similar to their counterparts in matter. When antimatter and matter collide, they instantly disintegrate into energy.

what is the name of the compound in the weed killer that many suspect is linked to non-hodgkin lymphoma (nhl)?
Glyphosate is the compound in the weed killer that many suspect is linked to non-hodgkin lymphoma (nhl).
What is Glyphosate?An pesticide called glyphosate is used to manage weeds and grasses. It serves as the primary ingredient in a variety of herbicides, including the well-known Roundup. Since 1974, glyphosate has been approved for use as a pesticide in the United States. It is also widely used in many other nations around the world. Weed killers and herbicides both use the term glyphosate as an active ingredient.
Glyphosate is a phosphonic acid created when the amino group of glycine reacts with the methyl group of methylphosphonic acid. The enzyme 5-enolpyruvyl-3-shikimate phosphate synthase is the only one that this herbicide targets (EPSPS).
A broad-spectrum herbicide is glyphosate. It cannot, therefore, be used to kill particular weeds or plants. Instead, it obliterates the majority of the area's broadleaf vegetation.
The mechanism of action of glyphosate is the inhibition of a plant enzyme involved in the synthesis of the three amino acids phenylalanine, tyrosine, and tryptophan.
Only a very small amount of glyphosate is absorbed into plants' roots; most of it enters through the leaves. Consequently, only grass and weeds that are actively growing can be killed by glyphosate. It is unable to prevent seeds from ever germination.

The general rise in Earth's temperature, especially as a result of global warming and other factors, is what causes the oceans' temperature to rise.
The solubility of oxygen decreases as water temperature, in this example ocean temperature, rises. This is due to the higher kinetic energy of oxygen molecules, which allows them to move out of the solution or body of water. In general, this implies that the diversity of marine life would decrease as the oxygen level would decrease and carbon dioxide levels increased. Due to ore CO2 dissolving in water, it makes the water acidic.
Acidification has the following consequences on the marine environment:
1. Species' shells and skeletons are dissolving as the acidity of the environment rises.
