The archaeal lipid showed here different from phosphatidylglycerol as stable ether bonds join the chains to the glycerol backbone at the SN-2 and SN-3 positions. L-glycerol-3 phosphate serves as phosphatidylglycerol's structural base.
Ester bonds hold the fatty acyl tails of phosphatidylglycerol to the glycerol backbone. Bacteria and Eukarya synthesize membrane lipids with hydrophobic fatty acid tails that are ester-bound to glycerol-3-phosphate (G3P), whereas Archaea create membrane lipids with hydrophobic isoprenoid lipid tails that are ether-linked to glycerol-1-phosphate (G1P) with the opposite chirality.
While bacteria and eubacteria create membranes made of fatty acids ester-bound to glycerol-3-phosphate, archaea manufacture isoprenoid lipids that are ether-linked to glycerol-1-phosphate (G1P) instead (G3P). The lipid makeup of bacterial and archaeal cell membranes and the properties of their cell walls are different from one another.

How many percent of the human body is composed of organic compounds?
Answer:
65 or 90
Explanation:
Answer:
approx 68%
Explanation:
Using the strand of mRNA below along with either of the codon charts,( place the amino acids in the correct order .)PheArgAsnThrMetGluStopTyrLysSer
Answer: Met - Glu - Tyr - Asn - Thr - Lys - Phe - Arg - Ser - Stop
Explanation:
mRNA: AUG GAA UAC AAU ACU AAG UUC CGU AGU UAA
Firstly, each codon is formed by three nucleotides, that codify for an amino acid.
In the chart of the left, the first nucleotide is represented on the left column, the second is represented by the row on the top, and the third nucleotide is represented by the column on the right. In the intersection of these three, is the amino acid corresponding to the nucleotide triplet.
The right chart, has to be followed from the center to the external part, so the first circle, that is divided in four, represents the first nucleotide, while the amino acid is located in the most external part of the chart.
the purpose of an emulsifier in margarine is to: a. keep water and fat from separating b. keep water and fat separated c. sustain the natural flavor of the ingredients d. retain the color
The purpose of an emulsifier in margarine is to keep water and fat from separating.
What is emulsifier?
Emulsifiers are food additives that the Food and Drug Administration has allowed. They aid in the blending of goods that contain immiscible food ingredients, such as oil and water. Many prepackaged and processed foods, such as mayonnaise, margarine, meats, ice cream, salad dressings, chocolate, peanut butter, and other nut butters, shelf-stable icing, cookies, crackers, creamy sauces, breads, baked goods, and ice cream, contain emulsifiers.
Simple emulsions consist of either water suspended in oil (w/o) or oil suspended in water (o/w). A typical o/w emulsion is milk, in which the water phase, or skim milk, and the fat phase, or cream, combine to create small droplets. Margarine, on the other hand, is a mixture of fat and vegetable oils that does not have an emulsion and contains drops of water or skim milk. Emulsifiers are required in both situations to stop the suspended droplets from aggregating and rupturing the emulsion.
Hence the correct answer is A; keep water and fat from separating.

a fatty acid in which ALL carbons in the hydrocarbon tail are connected by single bonds
Which one of these matches this
A fatty acid is referred regarded as being saturated if there are only single bonds between nearby carbons in the hydrocarbon chain.
(Fatty acids are saturated with hydrogen; in a saturated fat, the carbon skeleton is connected to as many hydrogen atoms as is feasible.)
How do saturated and unsaturated fatty acids differ?In terms of the number of double bonds in the fatty acid chain, saturated and unsaturated fat differ from one another. When compared to unsaturated fats, which include at least one double bond in the fatty acid chain, saturated fats do not contain double bonds between the individual carbon atoms.
The body cannot produce omega-3 fatty acids, a particular form of fat. Because they are a necessary fat, they are required for survival. We obtain the necessary amounts of omega-3 fatty acids from the meals we eat.

Gel electrophoresis is a method used to split DNA fragments (or different macromolecules, which includes RNA and proteins) primarily based totally on their length and price.
Electrophoresis includes jogging a modern via a gel containing the molecules of interest. Based on their length and price, the molecules will tour via the gel in special instructions or at special speeds, permitting them to be separated from one another.
All DNA molecules have the identical quantity of price in keeping with mass. Because of this, gel electrophoresis of DNA fragments separates them primarily based totally on length only. Using electrophoresis, we are able to see what number of special DNA fragments are found in a pattern and the way massive they're relative to 1 another.

Organisms that symbiotically coexist with another cell or creature are known as endosymbionts. Others adhere to the surface of cells, while others are located inside cells (intracellular) (extracellular). Relationships that are symbiotic are those in which both parties gain. Endosymbiosis is a type of symbiosis in which the symbiont resides inside the body of its host; this symbiont is referred to as an endosymbiont in this situation. Rhizobium's partnership with plant legumes is an illustration of an endosymbiosis. The endosymbiont found in the roots of legumes is rhizobium. Essential eukaryotic organelles of endosymbiotic origin are mitochondria and chloroplasts. These organelles are divided by dynamic cell processes.

Proteins that assist in the movement of substances across membranes can be classified into two types based on how they move solutes across a membrane: and transporters.
a. True
b. False
The given statement that Proteins that assist in the movement of substances across membranes can be classified into two types is True.
The second most important component of plasma membranes is protein. Membrane proteins fall into two basic categories: integral and peripheral.
Integral membrane proteins: Some proteins stick only partway into the membrane, while others stretch from one side of the membrane to the other and are exposed on either side. Integral membrane proteins are those that have at least one hydrophobic region that anchors them to the phospholipid bilayer. Transmembrane proteins may cross the membrane just once, or may have as many as twelve different membrane-spanning sections. The portions of an integral membrane protein found inside the membrane are hydrophobic, while those that are exposed to the cytoplasm tend to be hydrophilic.
Peripheral membrane proteins: On both the inside and outside of membranes, peripheral membrane proteins can be found, often bound to phospholipids or integral proteins. Peripheral membrane proteins are typically more loosely linked than integral membrane proteins because they do not adhere to the hydrophobic core of the membrane.

The aerobic threshold is the level of physical effort at which a person's cells are just beginning to carry out fermentation to meet some of their energy needs. Marathon runners try to stay at or below the aerobic threshold so that they can go longer distances without experiencing difficulty. While running up and down the hills of San Francisco, the runner was focused on trying to maintain the pace he had when he was running on flat land. What impact did this focus have on his ability to maintain his aerobic threshold?
The focus will negatively impact the ability of the runner to maintain his aerobic threshold because more effort would be needed when running up the hill.
What is aerobic energy?Aerobic energy is the energy generated as a result of aerobic respiration, respiration that takes place in the presence of oxygen.
Aerobic respiration differs from anaerobic respiration because the latter does not require energy. More amount of energy is generated during aerobic respiration than during anaerobic respiration.
In humans, anaerobic respiration only occurs during highly intense activities when oxygen availability is no longer enough to supply the required energy.
More effort/energy is required to run up a hill than to run on the surface, especially if the same pace is to be maintained on both. Thus, if a runner is focusing on maintaining his aerobic threshold, he should not exert more effort to climb up a hill. Instead, he should reduce the pace of his running.
Otherwise, he will break his aerobic threshold and anaerobic respiration will set in.
