Answers

The correct answer is C. They contain large amounts of stored chemical energy. Nevertheless it is also true that we use them, because at that time our technology was only capable of burning coal to obtain energy, and later on due to economical influences.

for the codon: 5'-agu-3', what are the last two nucleotides in the anticodon (5' to 3')?
a. 5’-CU-3’
b. 5’-GA-3’
c. 5’-AU-3’
d. 5’-AG-3’
e. 5’-UA-3’
f. 5’-UC-3’

Answers

The last two nucleotides in the anticodon for the codon 5'-AGU-3' (5' to 3') are 5'-CU-3'.The process of protein synthesis begins with transcription, during which the information encoded in DNA is copied to RNA.

The process of transcription:

During the process of transcription, the DNA strands unwind, and the RNA polymerase adds nucleotides complementary to the template strand. The newly synthesized RNA transcript is then translated into a protein sequence during the second step, known as translation.

The process of translation:

During translation, the mRNA is read by ribosomes, which then create a protein sequence from the amino acid building blocks dictated by the mRNA sequence. The sequence of nucleotides in mRNA is used to determine the sequence of amino acids that make up the protein chain.

The sequence of nucleotides in the codons corresponds to the sequence of nucleotides in the anticodons. Therefore, the last two nucleotides in the anticodon for the codon 5'-AGU-3' (5' to 3') are 5'-CU-3'. The anticodon is complementary to the codon, and it is the section of the tRNA molecule that binds to the codon sequence on mRNA during translation. The nucleotides in the anticodon are complementary to the nucleotides in the codon.

The receptors in the inner ear that provide sensations of gravity and linear acceleration are in the __________.

Answers

The receptors in the inner ear that provide sensations of gravity and linear acceleration are in the vestibular system.

What is vestibular receptors?

The vestibular receptors are located the inner ear, next to the auditory cochlea. They track head turns, linear motion, and tilts in relation to gravity and convert these motions into neural signals that may be communicated to the brain.

Each ear contains five vestibular receptors, including two otolith receptors (utricle and saccule) that transduce linear accelerations and three semicircular canals (horizontal, anterior, and posterior) that transduce rotating angular accelerations.

The semicircular canals and otolith organs work in concert to maintain a stable head position in relation to gravity in all three dimensions.

A small peptide was found to contain equimolar amounts of the following amino acids: arginine, glutamic acid, glycine, lysine, methionine and phenylalanine. Individual samples of the peptide were treated with the following agents with the results noted: Reagent Specificity Trypsin Lys, Arg (C) Chymotrypsin Phe, Trp, Tyr (C) Staphylococcus V8 protease Glu, Asp (C) Pepsin Phe, Trp, Tyr (N) Cyanogen bromide Met (C) a) trypsin: arginine and a pentapeptide b) cyanogen bromide: two tripeptides c) S. aureus V8 protease: lysine and a pentapeptide d) chymotrypsin: a dipeptide and a tetrapeptide, with the latter showing absorbance at 280nm. What is the primary structure of the peptide? Explain each piece of evidence given and the reasoning that led to your answer.

Answers

The primary structure of the peptide in question is Arg-Glu-Gly-Lys-Met-Phe. This structure can be deduced from the information given in the question.

Firstly, the reagents and their specificities indicate that each of the amino acids in the peptide are cleaved at different points. Trypsin cleaves Lys and Arg at the C-terminus, while S. aureus V8 protease cleaves Glu and Asp at the C-terminus. Additionally, Cyanogen bromide cleaves Met at the C-terminus, leaving two tripeptides, and finally Chymotrypsin cleaves Phe, Trp and Tyr at the N-terminus, leaving a dipeptide and a tetrapeptide with absorbance at 280nm.

When the peptide structure is drawn based on the cleavage sites, it becomes clear that the primary structure of the peptide is Arg-Glu-Gly-Lys-Met-Phe. This structure, therefore, best explains the observations made by the reagents and the absorbance data.

describe the process by which a germ cell’s complement of chromosomes is halved in the formation of gametes.

Answers

The process by which a germ cell’s complement of chromosomes is halved in the formation of gametes is called meiosis.

Meiosis is a type of cell division that reduces the number of chromosomes in a germ cell by half, resulting in four haploid (n) daughter cells, each with half the number of chromosomes (half the genetic material) of the parent cell. The process of meiosis begins with a diploid (2n) parent cell containing two sets of chromosomes (one from the mother and one from the father). During prophase I, the chromosomes condense and the nuclear membrane breaks down. Homologous chromosomes (chromosomes with similar genetic information) pair up to form tetrads. During metaphase I, the tetrads line up on the metaphase plate. At anaphase I, the homologous chromosomes separate and move to opposite ends of the cell. Then, during telophase I, the cell divides and two daughter cells are formed.

Yes, it is definitely possible that two individuals with type A blood ever produce any offspring with type O blood.

What is a Blood group type?

A blood group type may be characterized as the classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. In humans, there are four types of blood groups are there.

A blood group: \(I^AI^A or I^AI^O\). B blood group: \(I^BI^B or I^BI^O\). AB blood group: \(I^AI^B\). O blood group. \(I^OI^O\).

The blood grouping in humans is an example of co-dominance. The blood group of an individual or offspring is determined by the respective blood group of its parents. Parents with type A blood have the probability to produce any offspring with type O blood in the sense that they fuse their both specific gametes of \(I^OI^O.\)

Therefore, it is definitely possible that two individuals with type A blood ever produce any offspring with type O blood.

In primary succession of sand dunes, the first species to colonize are a. lichens. b. grasses. c. herbs. d. mosses.

Answers

In primary succession, the first organisms to colonize a barren habitat are called lichens species.

Sand dunes are an example of a harsh, inhospitable environment where primary succession can occur. The first species to colonize sand dunes are usually lichens. Lichens are symbiotic organisms that consist of a fungus and an alga or cyanobacterium.

They can tolerate harsh environmental conditions and can grow on bare rock or soil. Over time, as lichens break down rocks and produce organic matter, soil begins to form, which provides a substrate for other plants to grow. Grasses and other herbaceous plants are typically the next species to colonize sand dunes after lichens, and they further stabilize the soil and provide resources for other species.

Individuals with a condition known as "prosopagnosia" cannot recognize faces. Their perceptual abilities are intact, and they can accurately describe features such as eye color, size of the nose, and shape of the mouth. They can even tell you whether someone is attractive. However, they cannot recognize anyones face, not even the faces of their friends and family. Dr. Joseph DeGutis has been conducting research and trying to develop a training regimen that would allow patients with prosopagnosia to improve their recognition abilities. Patients complete a battery of perceptual tests to determine their baseline performance (a pre-test) and then are trained for six days on a facial categorization task. They are tested again (a post-test) to determine their levels of improvement. Would it be valid for Dr. DeGutis to use the independent-measures t test to test whether the training leads to an improvement? No, because Dr. DeGutis is using a repeated-measures (within-subjects) research design. In this type of design, the study populations are not independent.
