You aim to chemically synthesize four peptides with the following one-letter amino acid sequences: TIGER, PANTHER, CHEETAH, and CAT. a) Which one of these peptides will have the lowest pl? Give a reason for your answer. You are not required to calculate the pls of the peptides to answer this question. A qualitative knowledge of the ionization properties of amino acids discussed in class is sufficient to answer this question. (2 pt) b) Based on what we learned in the lectures, draw the titration curve for the TIGER peptide in the pH range 0-14. Make sure to label the two axes, and the pki, pk, and pkr values on the curve. If there are multiple R groups that titrate, indicate the pkes as pKR, PKR etc. You are not required to write out the chemical structures of the various titration intermediates. (2 pt)
Answers
At a pH above 10.76, the Arg residue will be mostly in its deprotonated form and the net charge of the TIGER peptide will be positive.
What is the expected titration curve?a) The peptide with the lowest pI (isoelectric point) will be TIGER. The pI is the pH at which the peptide has an overall neutral charge. The TIGER peptide has an acidic residue (Glu, pI = 4.25) and a basic residue (Arg, pI = 10.76) which will balance out each other's charges. PANTHER, CHEETAH, and CAT all have more basic residues and therefore will have a higher pI.
b) The titration curve for the TIGER peptide would have the following characteristics:
X-axis: pH
Y-axis: net charge
pK1: Glu (4.25)
pK2: Arg (10.76)
As the pH continues to increase, the Arg residue will begin to deprotonate and the net charge will become increasingly positive. At a pH around 10.76, the Arg residue will be completely deprotonated and the net charge of the TIGER peptide will be positive.
At a pH above 10.76, the Arg residue will be mostly in its deprotonated form and the net charge of the TIGER peptide will be positive.

The correct option is B. polarization. A particular kind of lens known as a Polarized lens alters the path of light rays point A to point b B.
Define the term Polarized lens?In order to improve eyesight and eye safety outdoors, polarized lenses are a sort of treated lenses intended to reduce glare as well as eye strain.
Outdoor glare is lessened with polarized sunglasses because they have been chemically altered to block part light from getting through the lenses. For people who spend a lot of time outdoors, polarized prescriptive sunglasses might be a smart option because they better block out strong light that causes eye strain than normal sunglasses.Before reaching a target, light must pass through two polarizing filters, and if the filters are 90 degrees apart, the target will not get any light.

According to this view, people have the "innate facility" or instinct to learn languages from birth. The primary argument used in favour of the LAD was the argument from the poverty of the stimulus, which contends that children would not be able to learn language as quickly as they do if they did not possess a significant amount of innate knowledge of grammar. This is because they rarely receive direct instruction in their first language and never have access to contradictory information.

Although eukaryotes and prokaryotes both engage in cell division, they do so in different ways. In particular, eukaryotic cells divide using the processes of mitosis and meiosis.
Mitosis results in two capitals that are identical to the original nexus. Meiosis, on the other hand, results in four capitals, each having half the number of chromosomes of the original cell. In creatures, meiosis only occurs in the cells that give rise to the coitus cells( gametes), i.e., the egg and the sperm.

Mitosis is the process of cell division where one parent cell divides to form two daughter cells. These cells are similar to each other as well to their parent cell. The chromosomal number remains same in both the daughter cells as that to their parent cell and this is why it is also called equational division.
Meiosis is the process where one parent divides to form 4 daughter cells and that have half the number of chromosomes, thus it is termed as reductional division.

Answers
Benedict's reagent is the best choice for the detection of sugar.
It is a solution of copper ions that is used to test for the presence of reducing sugars. The principle behind this test is that reducing sugars have the ability to reduce copper ions to copper oxide, which forms a precipitate and changes the color of the solution. This change in color can be used to identify the presence of reducing sugars.
Kovacs Reagent is not used for the detection of sugar. It is a reagent used to detect the presence of primary and secondary amines. It works by creating a color change when an amine reacts with the reagent.
The iodine reagent is not suitable for detecting sugar. It is a reagent that is used to test for the presence of starch. The principle behind this test is that when iodine is added to a solution containing starch, the iodine molecules will bind to the starch molecules and create a complex that results in a color change.
In summary, Benedict's reagent is the best choice for detecting sugar due to its ability to detect reducing sugars and its sensitivity to detect the presence of sugar in a sample.

Acetone molecules can position themselves similarly to ethanol molecules to form a tight surface with hydrogen bonding.

The study of human biological variation and evolution is known as biological anthropology.
Human evolution and biological diversity (both past and present) are studied by physical anthropologists in the context of culture, history, and behavior. Nonhuman primates, such as chimps, are also studied by some physical anthropologists.
The beginnings of language and speech provide details about human evolution.) Biological Anthropologists do not study: -How knowledge of how to dress is passed down from generation to generation. (This is an example of something a cultural anthropologist might investigate.

Peptidoglycan is a component of the bacterial cell membrane that protects the cell from bursting owing to turgor and keeps the cell shape. Peptidoglycan, which is made up of glycan chains joined by short peptides, creates a net-like macromolecule that wraps around the cytoplasmic membrane.

The peptidoglycan cell wall and the one or two membranes present also present a three-dimensional shape to the bacterial cell. The overall shape and arrangement of bacteria are genetically determined so that each rubric of bacteria has a characteristic shape( round, rod, helical, etc.)
Peptidoglycan( murein) is an essential and specific element of the bacterial cell wall set up outside the cytoplasmic membrane of nearly all bacteria( Rogers et al., 1980; Park, 1996; Nanninga, 1998; Mengin- Lecreulx & Lemaitre, 2005). Peptidoglycan provides severity to the cell wall; the cell walls of Gram-positive bacteria may contain up to 40 layers of peptidoglycan, conferring significant mechanical strength.
Peptidoglycan is a rigid envelope girding the cytoplasmic membrane of the utmost bacterial species. It helps cover bacterial cells from environmental stress and helps save cell morphology throughout their life cycle. Peptidoglycan biosynthesis is also an important controller of bacterial cell division.
