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.

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)
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.

Which of the following reagents is best suited for the detection of sugar? Multiple Choice KovacsbiuretBenedict'siodine
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.

On Earth, one day is the time it takes Earth to orbit the Sun one time.
A solar eclipse occurs when the Moon passes between the Earth and Sun.
A lunar eclipse occurs when a Full Moon passes directly behind Earth and is
covered in Earth's shadow.
The time it takes Earth to revolve once around the Sun is a year.
The position of the Moon in relation to the Earth and Sun at a given point
determines its phase.
Tides are caused by the gravitational pulls between the Earth and the Sun.
Answer:Most of our lives, we are focused on what is in front of us. When we gaze at the stars, we reflect on our place in the universe. An eclipse event brings that reflection into more concrete terms.
Two types of eclipses are visible from Earth, an eclipse of the moon and an eclipse of the sun. A lunar eclipse occurs when the Earth moves between the sun and the moon, blocking the sunlight that is normally reflected by the moon. A solar eclipse occurs when the moon is directly between the sun and the Earth, casting a shadow on the Earth.
bar-headed geese migrate from their breeding grounds to their wintering grounds by flying over the highest peaks of the himalayan mountains where oxygen levels in the air are extremely low, and yet these birds can produce enough muscle power to complete the arduous journey over the tops of the mountains. match the following research questions about this amazing feat with the appropriate area of biology that could investigate each question.
the terms are: 1- Ecology and Ethology, 2-Physiology, 3- Comparative Anatomy and Physiology, 4- Comparative Genomics and Evolutionary Biology
Ecology is the study of the interactions between organisms and their environment. It deals with the distribution, abundance, and dynamics of living organisms and their interactions with each other and their physical and chemical environment.
Ethology is the study of animal behavior, including how and why animals behave the way they do. It focuses on the mechanistic and evolutionary causes of behavior, and how behavior is influenced by the animal's environment.
Physiology is the study of the functions and processes of living organisms and their parts, including the physical and chemical mechanisms that underlie them. It deals with how organisms, organ systems, organs, cells, and biomolecules carry out the chemical and physical functions that exist in a living system.

The complete question is:
Bar-headed geese migrate from their breeding places to their cooler climes by flying over the highest peaks of the Himalayan mountains, where oxygen levels in the air are extremely low, and yet these birds can produce enough muscle power to complete the arduous journey. Match the following research questions about this incredible feat with the appropriate biological area that could investigate each question.
1)How do geese use environmental cues and landmarks to determine the timing and direction of their migration over the mountains? How do they get around?
2)How do the circulatory and respiratory systems cope with increased oxygen consumption in the face of low oxygen air?
3) Is the number of mitochondria (cell energy producers) in Bar-headed Geese muscle cells greater than in other species of geese with less demanding migration routes?
4) What DNA sequences are shared by species that can survive in low-oxygen environments, such as penguins and Bar-headed Geese that fly over the Himalayan peaks?
