A rapidly labeled RNA fraction of the nucleolus has been isolated and partially characterized. This RNA component appears to be a precursor of transfer RNA.
It contains neither pseudouridine nor methylated bases, and is unable to form amino acyl RNA.
Therefore , it resembles transfer RNA in base composition and molecular weight also serves as a substrate for in vitro methylation to a greater extent than transfer RNA.

Can biodegradable pollutants cause environmental problems? Explain your answer.
I would have to say YES
Biodegradable waste can create an environment problem if it is disposed and the mass is longer than the fermentation.
Hope this helps
Yes, biodegradable pollutants cause environmental problems if they accumulate in the enviroment without being decomposed.
The environmental impact of biodegradable waste can be seen when the food waste is disposed of and accumulates over a longer period of time than it decomposes, it creates a greenhouse gas called methane. This methane is produced by microorganisms.
Biodegradable wastes produce a large number of microorganisms around them, which can lead to an increase in the spread of diseases caused by microbes in humans, plants, and animals. They can also produce bad odors on burning because of the emission of gases.

How does the size of the fetal face relate to the cranium? how does this compare to the adult skull?.
The face is foreshortened and it is overshadowed by the large cranium. While the mandible and maxillae are very tiny.
Cranium is the outer layer that protects the skull. It consists of three parts: the frontal bone, occipital bone, and two parietal bones.
The frontal bone is a single bone that transforms into a forehead and it is positioned atop the eyes' orbit.
The frontal bone also forms both sides of the upper jawbone or maxilla. While the two parietal bones form the top and side of the human skull.

Retinoic acid was found to regulate the cell shape and death of E-FABP -immunoreactive septoclasts in the growth plate cartilage of mice.
How does retinoic acid regulate the cell shape and death of immunoreactive septoclasts?The transverse septa of the growth plate (GP) cartilage at the chondro-osseous junction have been thought to be resorbed by septoclasts, that are mononuclear cells with numerous projections (COJ). In a recent study, the expression of the fatty acid-binding protein of the epidermis type (E-FABP, FABP5) and the location of the peroxisome proliferator-activated receptor (PPAR) were described, which controls cell survival and proliferation. On the other hand, the GP cartilage has a lot of retinoicacid (RA), which can bind to E-FABP. These details allow for the hypothesis that RA in the GP controls septoclast growth and death by being absorbed into them during cartilage resorption.

The morphological difference between atlas/axis vertebrae and typical vertebrae is that typical vertebrae consist of a body, vertebral arch, and transverse processes whereas atlas/axis contain different structures according to the functional requirements.
The atlas, as well as axis vertebrae, are morphologically different from typical vertebrae by the presence of the body, vertebral arch, and transverse processes in typical vertebrae. The vertebral column is made up of 26 serially arranged bones called vertebrae. Each vertebra has a central hollow portion through which the spinal cord passes. The first vertebra is known as the atlas and the second vertebra is known as the axis.
These both are known as atypical vertebrae because they are morphologically distinct from the typical vertebrae. The typical vertebrae have a body, vertebral arch, and transverse processes which are not present in atypical vertebrae.

Lipids are macromolecules composed of fatty acids. The diagram represents the inability of the lipids to break in the water. Thus, the inability to break down in the water is correct.
What are lipids?
As they are big molecules comprised of the monomers of the fatty acid chains and glycerol bound together by chemical bonds, lipids are referred to as polymers. They consist of phospholipids, steroids, waxes, hormones, oils, fats, and more.
Along with carbs, they are molecules that store energy and function as messengers in the form of hormones. They can store energy for a longer time in adipose (fat) cells. They produce cholesterol, blood cells, and a component of the cell membrane.
Due to the fact that they are non-polar molecules with hydrophobicity and hydrophilicity, they are soluble in an organic solvent but not in water. They don't dissolve and stay whole in the water molecule.

A sampling distribution is a statistical probability distribution derived from repeated sampling of a given population. It represents a population's range of probable outcomes for a statistic, such as the mean or mode of some variable.
Sampling distributions explain the range of values for various sample statistics. While the mean sampling distribution is the most popular, they can also characterize other statistics such as standard deviation, range, correlation, and test statistics in hypothesis testing. The sampling distribution also depicts a statistic's frequency.

decide whether the following statement is true or false, and then explain why: "in an organism whose genome has been sequenced, identifying the mutant gene responsible for an interesting phenotype is as easy for mutations induced by chemical mutagenesis as it is for those generated by insertional mutagenesis"
FALSE
This is false because when the genome is sequenced for a particular organism, it is easy to compare the sequence with the reference and check if there is any mutation that has led to change in phenotype. The chemical mutagenesis is basically change of one base pair at a time and hence it is easy to sequence and find out which base pair has changed leading to the mutagenesis. However, when it comes to insertional mutagenesis, this occurs using either T-DNA or transposons and it is caused by viruses or transposons which leads to creation of such mutations. The TE (transposable elements) are DNA sequences which move from one location to another within a genome and hence when mutations take place due to this, it becomes difficult to compare it with the reference to identify the mutations.

On polysomes linked to the membranes of the ER, proteins are produced that will eventually be integrated into membranes, retained in lysosomes, or released from the cell.
During translation, these ribosomes separate the proteins they create and deposit them into the membrane cisternae of the ER.The majority of secreted proteins in eukaryotic cells are co-translated into the rough ER from ribosomes. However, some proteins, especially those with "weak" signal sequences or short polypeptides, can enter the ER post-translationally.For the remainder of translation, proteins lacking a signal peptide remain in the cytosol.
