How many amino acids are there in A peptide, B peptide and C peptide in human insulin???
Answer:
Insulin is composed of an A chain of 21 amino acids and a B chain of 30 amino acids. C-peptide is a peptide composed of 31 amino acids
Explanation:
Insulin is composed of an A chain of 21 amino acids and a B chain of 30 amino acids, the chains being held together by two disulfide bonds. A third disulfide bond is present within the A chain. Human insulin differs from porcine insulin by a single amino acid and from beef insulin by three amino acids.
Explanation:
Dashed circles around either an R or K indicate sites of peptidase cleavage that result in generation of the mature insulin that is comprised by two separate peptides: the A chain with 21 and the B chain with 30 amino acids. A third C peptide with 21 amino acids served as a linker between the A and B chains.

A red blood cell has a salt concentration of 0.9%. What will happen if it is placed into
a 0.8% salt solution? The red blood cell will
burst
remain the same
shrink then grow
shrink
Answer:
Shrink
Explanation:
The blood cell would shrink because of osmosis. The molecules move with the concentration gradient so water molecules will move outside of the cell where there is less water than inside of the cell.
Blood cells are the main constituents of the circulatory system and carry the most vital function of oxygen transportation. Blood cells have a specific concentration and osmotic pressure to remain vital.
The correct answer is:
Option D. Shrink.
This can be explained as:
Cells have a tendency to shrink in hypertonic solutions while swells in hypotonic solutions.0.8% of the salt solution will act as a hypertonic solution and the RBC placed in it will shrink.When cells are placed in hypertonic solution it loses their water content to the outside surface and hence shrink.Therefore when the red blood cells are placed in 0.8% salt solution they will shrink.

Answer:
- Can leverage Next Generation Sequencing technology to identify and characterize organisms
- Has resources to support analysis at the DOE-JGI site.
- Can identify microbiologic organisms without traditional isolation and culturing of individual organisms.
Explanation:
Metagenomics can be defined as the study of whole genomes of biological communities recovered from environmental samples. This genomic field has enabled the discovery of new species (microorganisms) and their effects on the environment. Next-Generation Sequencing (NGS) technologies allow to obtain huge amounts of genomic data, which has been a limitation in genomics and metagenomics. Metagenomic NGS (mNGS) is a technique used for sequencing nucleic acids present in a biological sample containing mixed populations of microorganisms. Finally, the Department of Energy Joint Genome Institute (DOE JGI) is a referent in metagenomic analysis, especially in genome assembly data obtained from microbial communities. This Science User Facility has developed a series of bioinformatics tools and databases in order to analyze metagenomic information.

Write a scientific explanation to explain how natural selection and adaptation increase or decreases the chances of survival for the mice if they entered one another’s environment.
Answer:
Natural selection is a factor of biological evolution, by means of which individuals who possess a certain characteristic tend to prevail over those who lack such characteristic. Thus, by reproducing, individuals with favorable characteristics end up imposing their own set of characteristics, taking control of the environment in which they develop and relegating other individuals or condemning them to their extinction or displacement.
Thus, in the case, if some mice entered the environment of others, most likely they would not be able to adapt to the conditions to which the original group of that environment had previously adapted. In this way, natural selection itself would make the new mice end up disappearing from it, in favor of the mice that already lived there and that, therefore, had adapted their characteristics to those of the environment.

In the laboratory, a genetics student crossed flies with normal, long wings to flies with mutant, dumpy wings, which she believed was a recessive trait. In the F1, all flies had long wings. In the F2, the following results were obtained: 672 long-winged flies 218 dumpy-winged flies The student tested the hypothesis that the dumpy wing is inherited as a recessive trait by performing chi-square analysis of the F2 data.
Determine:
a. Chi-Square Value.
b. Degrees of freedom.
c. Reject or fail to reject the hypothesis.
Answer:
a. Chi-Square Value = 0.12
b. Degrees of freedom = 1
c. Reject or fail to reject the hypothesis = fail to reject the hypothesis
Explanation:
Available data:
Cross: long wings to flies with mutant, dumpy wingsF1) 100% long-winged fliesF2) 672 long-winged flies 218 dumpy-winged flies Hypothesis: the dumpy wing is inherited as a recessive traitLet us name the allele for Long L and the allele for dumpy l
The number of observed individuals:
Total number: 890 flies (672 + 218) Long-winged = 672 Dump-winged = 218In the F2 generation, if l was a recessive allele and L a dominant allele, exhibiting complete dominance, we would expect a 3:1 phenotypic ratio.
Cross: Ll x Ll
Gametes) L l L l
Punnett square) L l
L LL Ll
l lL ll
F2) 3/4 LL + Ll long-winged individuals
1/4 ll dump-winged individuals
From this ratio and the total number of individuals in the F2 generation, we can get the expected number of individuals:
4 possible genotypes ------- 890 individuals
3 LL + Ll genotype ------------X = 667.5 long-winged individuals
1 ll genotype ---------------------X = 222.5 dump-winged individuals
Chi square = ∑ (O-E)²/E
LL + Ll = (O-E)² /E
LL+ Ll = (672 - 667.5) ² / 667.5
LL + Ll = 0.03
ll= (O-E)²/E
ll= (218 - 222.5)² / 222.5
ll= 0.09
Chi square= ∑ ((O-E)²/E) = 0.03 + 0.09 = 0.12 Freedom Degrees = genotypes - alleles = 3 - 2 = 1 Significance level = 0.05 Table value/Critical value = 3.84
0.12 < 3.84 meaning that there is enough evidence to reject the null hypothesis.
Fail to reject the hypothesis. The genotypes in the population might be in equilibrium H-W. L is the dominant allele, and l is the recessive allele. The dumpy wing is inherited as a recessive trait.

Molecule X is most likely what kind of compound/molecule? *
Molecule X is an enzyme to which the starch is bonded and starch- enzyme complex is formed.
What is an enzyme?An enzyme is a type of protein that acts as a catalytic agent in chemical reactions. Enzymes play a crucial role in metabolism and other biological processes by increasing the rate at which chemical reactions occur.
Enzymes work by lowering the activation energy needed for a reaction to take place. In other words, enzymes make it easier for the reactants in a chemical reaction to come together and form products. This is accomplished by the enzyme binding to one or more of the reactants, known as substrates, and bringing them into a specific orientation that promotes the reaction. Once the reaction has taken place, the enzyme is free to bind to another set of substrates and catalyze the reaction again.
Enzymes are highly specific, meaning that each enzyme typically catalyzes only one particular reaction or a small group of closely related reactions. They are also highly efficient, able to catalyze millions of reactions per second.

Which of the following is an example of a learned response? OA A child figures out how to ride a bicycle. O B. An adult salmon is able to return to the river where it hatched. OC. A plant turns to follow the sun during the day. OD. A man blinks when an object is tossed toward his face.
Answer:
Explanation:
I would say A. Learning to ride a bicycle is a process of getting on and falling off. You have no idea how to do it properly without practice. That's learned.
But look out for D. I'm not sure that that isn't instinctive. Somewhere along the line I think even a baby knows not to let his/her eyes be touched. Is it learned? It's close but A is a much better answer.
The salmon is instinctive. The plant doesn't learn to turn towards the sun. It does so because more food is produced.
Yes, it's A.
A is the only option that is not instinctual. Riding a bicycle is something that has to be taught (and even if you weren't taught to ride a bike, you had to figure it out by trial and error.)
The other options are instinctual and reflexive responses. The salmon returning to the river is a behavior that is pretty much hard-wired into the salmon's brain. The plant turns to follow the sun because it is a source of light and energy.
The other user expressed uncertainty as to option D, but in fact, option D is very much a reflexive, instinctual response as well. To flinch or blink when something abruptly moves towards you is not a choice or something you have to be taught — it's a reflex, something you can't control.
