The new hypothesis could be that there is another alternative factor that is negativey afecting dwarfs survivorship.

The previous hypothesis of high levels of phosphate killing mussels is not necessarily disproved.  But the death of mussels from both the control and the treatment groups might be related to one of the controlled variables that could be actually afecting them.      

----------------------

Probably different levels of phosphate are also affecting invididuals´ survivor rates. However, the fact that mussels from all the aquariums died suggests that there is something else going on that caused the death of all the individuals.    

The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.  Individuals of the control group are selected from the same population as the treatment group. These two groups are identical in all aspects except for the independent variable, which changes in the treatment group but remains constant in the control group.

We know that mussels in this experiment were taken from the same population and grown under the same controlled conditions. Only the treatment group received phosphate, but all mussels died, not only the ones that receive phosphate. This result turns to be useful because it is indicating that there is another variable that is killing mussels. Phosphate might be a cause of death, but there is also something else. So the researchers should pay attention to the controlled variables, such as water quality, temperature, pH, food supply, light exposure, or others.  

These variables might be reflecting the real conditions under which mussels live. The results tell that one of these is related to individual death and could be a consequence of climate change or soil use, among other causes.

The correct answer is - B. Identification and binding of RNAP onto the promoter sequence.

Explanation:

Bacterial RNA polymerases have subunits known as Sigma factors responsible for the identification and specificity of promoter binding of RNAP and regulate the efficiency of RNA synthesis during transcription is initiated.

These bacteria producing the nonfunctional subunits of RNA polymerase or sigma factor will be unable to identify and tightly bind to promoter elements that are RNAP.

Answer:

An aminoacyl-tRNA synthetase (aaRS or ARS), also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its corresponding tRNA. It does so by catalyzing the transesterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA.

Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life.

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. There are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

If a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.

Stomata are the tiny pores present on the surface of the leaves. A huge amount of gaseous exchange may take place in the leaves through these pores for the purpose of photosynthesis.

During photosynthesis, these stomatal pores take carbon dioxide and water is gradually lost, in order to prevent this water loss in hot and humid conditions, the plant closes its stomata.

Therefore, if a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.

Development which basically ensures the protection of the environment in the long term is sustainable development. The correct option is D.

Sustainable development is defined as growth that fulfills the requirements of the moment without jeopardizing future generations' capacity to meet their own needs.

The financial, social, and environmental measurements of sustainable development are examined.

The authors contend that material-intensive conventional productivity recovery is unsustainable in the long term unless environmental and social factors are prioritized equally.

Environmental protection aims to preserve as well as restore a healthy natural environment.

Sustainable development incorporates ecologic, social, and economic goals in order to achieve long-term equitable growth that benefits both the present and the future.

Thus, the correct option is D.

by Emerging Technology from the arXivarchive page

December 3, 2009

One of the great mysteries of our Solar System is why Uranus is tilted on its side. Surely, if the solar system formed from the same rotating cloud of dust and gas, then all the bodies within it should rotate in the same way. And yet Uranus’ axis of rotation lies at 97 degrees to the plane of the solar system.

Answer:

cells will have glycogen molecules with branches of a single glucose residue

Explanation:

Glycogen debranching enzymes are proteins that catalyze the removal of branching from glycogen, which is a multibranched polysaccharide composed of glucose units and serves as a form of energy storage. These enzymes have two catalytic activities on a single polypeptide chain: glucosyltransferase and glucosidase activities, which are both required for glycogen breakdown. Glycogen degradation requires both glycogen phosphorylase and glycogen debranching enzymes. First, a glycogen phosphorylase acts to digest a glycogen branch down to four glucose residues. Subsequently, the debranching enzyme through its glucosyltransferase activity acts to transfer three glucose residues to a nearby branch of the glycogen chain. Finally, through its glucosidase activity, the debranching enzyme cleaves the remaining α-1,6 linkage in order to release free glucose.

Answer:

The correct answer is - P = 0.45

Explanation:

The Chi-square test is a test that determines the assorted genes independently. Here p-values used to make conclusions in significance testing.

If the p value is less than the significance level we expect or choose, then this null hypothesis is rejected in favor of the alternative hypothesis. It p value is greater than or equal to the significance level, then we fail to reject the null hypothesis.

So in this case, as the recombination rate is 49% so the p value which satisfies the conclusion will be around 0.45 and values near to it.
