Meaning of one tailed test and two tailed test

Answers

Answer 1

Answer:

Hypothesis testing is run to determine whether a claim is true or not, given a population parameter.

Explanation:

A test that is conducted to show whether the mean of the sample is significantly greater than and significantly less than the mean of a population is considered a two-tailed test.

What observation supports the claim that earth rotates

Answers

Answer:

The most direct observational evidence for Earth's orbital motion is the apparent shift of nearby stars after six months, as the Earth moves from one side of its orbit to the other. Because of the large distance to even the nearest start, this parallax shift is too small to been seen without a telescope.

One species called the naked mole-rat, has some unique differences. They have a social structure similar to that of ants and bees, they are smaller in size and are mostly ectothermic. They live in harsh, dry scrub land habitats and forage mainly on underground tubers which are widely dispersed. Why you think this species evolved back to an ectothermic life style rather than staying endothermic like all other mammals

Answers

Answer:

May be of the environment they live or genetics.

Explanation:

This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.

Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phosphate bonds per added nucleotide. Calculate how many protein molecules will have been made from an individual mRNA at the point when the energy cost of translation is equal to the energy cost of transcription. Assume that the nucleotides in the coding portion of the mRNA constitute 5% of the total that are transcribed.

Answers

Answer:

30 protein molecules per mRNA molecule

Explanation:

In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.

Apply: Suppose a template strand of DNA had the following sequence: T A C G G A T A A C T A C C G G G T A T T C A A What would be the complementary strand of mRNA?

Answers

AUG CCU AUU GAU GGC CCA UAA GUU

The corresponding nucleotide sequence is present on the coding strand. No complementary sequence exists on the template strand.

What changes occur in complementary strand from template?

The DNA strand from which the mRNA is produced is known as the template strand. The DNA strand opposite the template strand is known as the coding, or non-template, strand, and it has the same sequence as mRNA except T to U substitutions.

The template strand, one of the two exposed DNA strands, acts as a model for transcription.

The RNA product is essentially identical to the non template (or coding) strand of DNA and is complementary to the template strand.

Therefore, AUG CCU AUU GAU GGC CCA UAA GUU is the complementary strand of mRNA.

Writing Assignment So, you have learned about how the denaturation of proteins works during lecture, and you have seen examples in these videos. Now you will write a 2-3 page discussion of protein denaturation putting all that together Make sure you cover both the academic side (lecture knowledge) and practical side (what is done and observed in the lab). Make sure the answers to the following questions are contained in your report. Do NOT just answer them separately, but rather incorporate them seamlessly in your writing. This is a very broad topic, so comprehensive coverage is hardly expected, but you should demonstrate a good beginner's understanding. As usual, reference any and all resources you use.
a. What are the various levels of organization that any protein structure may have that gives it its 3-dimentional shape?Which of these changes during denaturation?
b. For each change made to a protein solution that you have seen or read about how might it affect the interactions that are involved in a protein's shape?
c. What is the difference between precipitation of a protein and its denaturation? How might you tell the difference?
d. If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if it were the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (Consider the enzymes that are active in your stomach, such as pepsin-discussed in Wikipedia.)
e. For changes that precipitate a protein, are some more likely than others to be denaturation?
f. Etc. If you find one aspect of what you've see more interesting, go ahead and learn more and expand that section of your report and keep the other sections more basic.

Answers

Solution :

Denaturing may be defined as the process where the protein they lose their shape and their function because there is a change in the pH level or in the temperature. Although the amino acids sequence also known as primary structure, it does not change. But the shape of the protein might change a little bit so much that it can become dysfunctional in which protein is considered to be denatured.

The enzyme, Pepsin, the breakdown protein in our stomach only operates at a very low pH level. At higher pH level, the pepsin's configuration the way the polypeptide chain is being folded up in a 3 dimension begins to change. The pH level of the stomach is maintained at a low level to ensure that pepsin continues for the digest protein and that it does not denature.

There are 4 levels of the protein structure --- they are the primary, the secondary, the tertiary and the quaternary.

The primary protein is a particular sequence of amino acids in each of the polypeptide chain that makes the protein. The final protein structure depends on this sequence.

Secondary structure arise from the interactions between the neighboring or nearby the amino acids as polypeptide starts folding into 3D form.

The tertiary structure is the most important of structural levels in determining.

The quaternary structure also applies to the proteins made from more than one polypeptide chain.
