What the Viceroy's color pattern evolved?

The Viceroy's color pattern has been evolved because the natural selection favoured them. The viceroy butterfly camouflage as the monarch butterfly as well as the exhibit Mullerian mimicry where as these two toxic species has the mimic each other for their benefit and by time natural selection has been favoured these.

Natural selection has been the process by which the reproductively fitest has the populations of the living organisms survive, adapt and change. The viceroy butterfly has the brush-footed butterfly having the dark orange colour with the black veins and row of the white spots on the border of its wings.

Monarch butterfly has the same as that of the viceroy except that it has the black horizontal stripes that has cross the bottom of its back wings. Species has refers to the group of the organisms which have the similar features and which are able to be interbreed to produce the viable and the fertile offspring.

Therefore, reproductive isolation prevents interbreeding between members of different species. It includes a collection of behavioral, evolutionary, and physiological processes.

what’s the chemical reaction for the digestion of fats.

Answers

Answer: The chemical reaction for the digestion of fats is when A triester is produced through the chemical reaction of three fatty acid molecules with glycerol, a molecule that contains three hydroxyl groups. When fats are broken down these fatty acid chains and glycerol are free for the body to use.

Explanation:

Lipids (fats and oils)

Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Bile is not an enzyme.

1. The more bases there are per codon the more information you can code for. There are only 22 different amino acids, in consequence we need minimum 3 bases per codon.

2. codon

three nucleotides—called a triplet or codon—codes for one particular amino acid in the protein. The nucleotide sequence in the DNA is first transcribed into a molecule of messenger RNA (ribonucleic acid).

3. Known as alpha helices and beta sheets, these stable folding patterns make up the secondary structure of a protein. Most proteins contain multiple helices and sheets, in addition to other less common patterns (Figure 2). The ensemble of formations and folds in a single linear chain of amino acids — sometimes called a polypeptide — constitutes the tertiary structure of a protein. Finally, the quaternary structure of a protein refers to those macromolecules with multiple polypeptide chains or subunits.

OKAY I THINK EVERYTHING IS RIGHT BUT SORRY IF WRONG ;)

The mRNA sequence could be translated into three different sets of amino acids because of the degeneracy of the genetic code.
Using the genetic code to translate the mRNA sequence, we get the following three possible sets of amino acids:Set 1: isoleucine-phenylalanine-leucine-serine-valine-arginineSet 2: isoleucine-asparagine-valine-leucine-serine-arginineSet 3: isoleucine-asparagine-leucine-serine-valine-arginine

What is a nucleotide sequence?

A nucleotide sequence is the order of nucleotides (the building blocks of nucleic acids) in a DNA or RNA molecule.

Nucleotides are composed of a sugar, a phosphate group, and a nitrogenous base, which can be adenine (A), cytosine (C), guanine (G), thymine (T) (in DNA) or uracil (U) (in RNA). The specific order of these nucleotides in a DNA or RNA molecule determines the genetic information that the molecule carries.

Is glucose more or less complex than the rest of the biomolecules? Explain.

Answers

Answer:

Less complex.

Explanation:

Glucose is both a monomer and simple sugar.

Glucose is a monosaccharide. It is a biomolecule. It is less complex than the rest of the biomolecules, such as proteins, lipids, and other complex carbohydrates like glycogen.

 

What is a biomolecule?

Biomolecules are present inside the cell. Carbohydrates, proteins, and lipids are some examples of biomolecules. Carbohydrates are divided into monosaccharides, disaccharides, and polysaccharides.

A monosaccharide has a single unit. Examples are glucose, fructose, etc. A disaccharide consists of two units. An example is maltose. Maltose is made up of two units of glucose connected by a glycosidic bond. An example of a polysaccharide is glycogen. Multiple sugar units are connected by glycosidic bonds to form glycogen. It is a storage product.

Carbohydrates are present on our cell surface as peptidoglycan. Protein is a biomolecule that is made up of amino acid monomers. They make the different structures of a cell, such as actin fibers, etc. Lipid is made up of hydrogen and carbon. Examples are cholesterol, phospholipids, etc.

Hence, in comparison to all other biomolecules, glucose is the simplest.

Draw and use algebra tiles to solve the equation.2x - 3 = 5 Please I need help!!!From "The Tyranny of Things" by Elizabeth MorrisOnce upon a time, when I was very tired, I chanced to go away to a little house by the sea. "It is empty," they said, "but you can easily furnish it." Empty! Yes, thank Heaven! Furnish it? Heaven forbid! Its floors were bare, its walls were bare, its tables there were only two in the house were bare. There was nothing in the closets but books; nothing in the bureau drawers but the smell of clean, fresh wood; nothing in the kitchen but an oil stove, and a few a very few dishes; nothing in the attic but rafters and sunshine, and a view of the sea. After I had been there an hour there descended upon me a great peace, a sense of freedom, of in finite leisure. In the twilight I sat before the flickering embers of the open fire, and looked out through the open door to the sea, and asked myself, "Why?" Then the answer came: I was emancipated from things. There was nothing in the house to demand care, to claim attention, to cumber my consciousness with its insistent, unchanging companionship. There was nothing but a shelter, and outside, the fields and marshes, the shore and the sea. These did not have to be taken down and put up and arranged and dusted and cared for. They were not things at all, they were powers, presences.And so I rested. While the spell was still unbroken, I came away. For broken it would have been, I know, had I not fled first. Even in this refuge the enemy would have pursued me, found me out, encompassed me.If we could but free ourselves once for all, how simple life might become! One of my friends, who, with six young children and only one servant, keeps a spotless house and a soul serene, told me once how she did it. "My dear, once a month I give away every single thing in the house that we do not imperatively need. It sounds wasteful, but I dont believe it really is. Sometimes Jeremiah mourns over missing old clothes, or back numbers of the magazines, but I tell him if he doesnt want to be mated to a gibbering maniac he will let me do as I like."The old monks knew all this very well. One wonders sometimes how they got their power; but go up to Fiesole, and sit a while in one of those little, bare, white-walled cells, and you will begin to understand. If there were any spiritual force in one, it would have to come out there.I have not their courage, and I win no such freedom. I allow myself to be overwhelmed by the invading host of things, making fitful resistance, but without any real steadiness of purpose. Yet never do I wholly give up the struggle, and in my heart, I cherish an ideal, remotely typified by that empty little house beside the sea.Which of the following words from the excerpt identify what Morris values more than things?Choose one answer from each group.
