Which statement correctly distinguishes the functions of proteins from other types of biomolecules?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the four major biomolecules have the following different functions
1) Nucleic acid (as in DNA and RNA): They are a sequence of nucleotides that store organism's genetic code. This nucleotide sequence in turn determines an organism's protein sequence.
2) Carbohydrates: They are important structural components of various "compositions" in an organism (such as the cellulose in cell wall and ribose in nucleotide). They also serve as energy sources for the body.
3) Lipids: They also serve as energy sources and are part of membrane composition (as in the case of the phospholipid cell membrane).
4) Proteins: They are major structural elements of cells. They serve as enzymes in many biological activity (such as hexokinase in glycolysis and DNA polymerase in DNA replication). They also form hormones (such as insulin) and antibodies (such as the Immunoglobulins).
outline the process of biogas production
Answer:
The production of biogas is the easiest way of extracting the energy from residues, under various factors.
Explanation:
It is produced from the organic residue – carbon, which degrades with the help of bacterias.
It can be produced using the anaerobic digesters and in this process biomass waste transforms into methane and this way produces the energy that is renewable and used for energy and heating.
Some pathogens, such as HIV, can be transmitted both vertically and horizontally. How do you expect virulence of such pathogens to compare with that of pathogens that are transmitted?
Answer:
Some pathogens are transmitted by a single route and others by several, the more transmission routes are recorded, the more pathogens they are, in the HIV virus the transmission is vertical and horizontal therefore it has high pathogenicity, on the other hand, the varicella virus is transmitted only by inhalation.
Explanation:
The vertical route is the transmission through childbirth, it is the moment in which the mother contacts the child's blood and transmits the virus, nowadays the vertical contagion of HIV is highly controlled.
On the other hand, the horizontal route is also called parenteral, it is one that consists of the inoculation of the virus through uncontrolled blood transfusions, intravenous drug addiction by syringe compartment, or uncontrolled injections.

What human activity provides a reasonable analogy for the movement of kinesin molecules along microtubules?a. running on a treadmill.b. climbing a rope hand over hand.c. shooting a fire hose at a beach ball.d. being one of many rowers in a boat .
Answer:
The correct answer is - option. b climbing a rope hand over hand is correct
Explanation:
The movement of the kinesin molecules led by the head of one kinesin followed by the second one after another same as one hand moves on the rope at a time and followed by the other hand during climbing the rope.
The movement of the kinesin microfilament is due to the increased affinity by ATP of the head of the kinesin for the microtubule. However, the hydrolysis of ATP decreases its affinity so it slides or moves to the plus end.
The sequential series of nucleotide triplets that are positioned in the A site of the ribosome during translation. A. Primary structure B. Exons C. Promoter D. Reading frame
Answer:
The correct answer is D.
Explanation:
Reading frame is a sequence of codons determined by nucleotides that are read in groups of three from a specific translation start codon, that is, it is a linear sequence of codons or triplets in a nucleic acid. It is one of three possible reading alternatives of a nucleotide sequence of a series of triplets, this means that, in a double-stranded DNA molecule, there are 6 possible directions in which reading frames can be opened; three in the forward direction and three in reverse.
Some individuals can develop kidney failure after consuming fava beans. What is the biochemical rationale for this observation?A. A deficiency of glucose-6-phosphatase that resulted in failure to synthesize essential red cell membrane proteins.B. A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.C. A deficiency of transketolase that resulted in the failure to provide ribose for the DNA and RNA needed to repair red cells.D. A deficiency of transaldolase that resulted in the failure to maintain glycolysis in the red cells. E. A deficiency of sedoheptulose that resulted in the failure to maintain the integrity of the red cells.
The correct answer to the question is option B
A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.
The deficiency of Glucose 6 phosphate dehydrogenase is a genetic disorder,when certain foods are consumed,the deficiency symptom to the enzyme is triggered and one of such food is Fava beans.
in Fava beans, Vicine is found, and this Vicine is an alkaloid glycoside.
Vicine is an oxidant,and it is toxic by causing disease favisim in individuals.The individual being affected are the ones that have hereditary loss of the Glucose 6 phosphate dehydrogenase enzyme.
But favisim only occurs when Fava beans is ingested fresh, that is without cooking it.
Following this,there is the development of acute intravascular hemolysis within 4-24hours after the ingestion of the Fava beans,there might also be a fall in the hemoglobin content of the blood and this may result in fatal condition.
But in cases that are acute, that is case of hemolysis, blood transfusion is vital and also in the case is kidney failure, dialysis must be done.
The reason why blood transfusion is very necessary is because the blood transfused may not have red blood cells that are deficient of Glucose 6 phosphate dehydrogenase,also the cells can have normal lifespan in the blood circulation of the recipient.
This Glucose 6 phosphate dehydrogenase is vital because it is a metabolic enzyme of Pentose phosphate pathway and it is also important for the metabolism of red blood cells.It also gives red blood cells protection from oxygen species that are harmful and reactive.
Option A is a metabolic disease that is
inherited which results in accumulation of glycogen and fat in liver.
Option C is as a result of deficiency in thiamine and malnutrition.
Option D is as a result of mutation in transaldolase gene.
Option E is as a result of genetic mutation.

Eukaryotic genomes have gene sequences that can code for more than one polypeptide sequence because _____.
Answer:
The correct answer would be -A pre-mRNA becomes mRNA by cutting out different introns
Explanation:
During the process of the RNA splicing, pre-mRNA has several specific segments of sequence that are identified by the spliceosome and then removed from the pre-mRNA. Specific parts that are removed are known as introns and the parts that stuck to become mRNA are exons.
Gene sequences in the eukaryotic genome can code for more than one protein due to removing the different introns every time to become mRNA from pre mRNA.
An operon in E. coli called the Gua operon, encodes proteins responsible for guanine biosynthesis. Two genes, guaA and guaB are under the control of a single promoter and operator, similar to the arrangement in the lac and trp operons. A repressor protein, purR, binds to the operator. In what conditions (high guanine or low guanine) do you suppose this repressor binds to the operator? Do you consider this a "repressible" or "inducible" operon? 3 pts
Answer:
Hight guanine"Repressible" operonExplanation:
An operon is a fragment of DNI with genes that encode for different proteins of metabolic vias. Operons are composed of a regulator gene (that codifies for the repressor), the operator region (that links with the repressor protein), and the promotor sequence (RNA polymerase recognizes the promotor where it begins the RNA synthesis).
The repressor deactivates the expression of a gene when binding the operator of that gene. This binding does not allow the production of mRNA, and hence, proteins that this molecule should synthesize.
This protein has a negative effect on genic expression impeding the transcription of RNA from DNA.
Operons might be inducible or repressible. When the operon is inactive, and a little inductor protein activates it, then the operon is inducible. On the contrary, the repressible operon is the one that is normally active, but the little corepressor protein inactivates it.
During high guanine concentration, the repressor protein must act to regulate the amount of guanine in the environment. Hence it links the operator of genes guaA and guaB to stop the biosynthesis. The operon was initially active, but then by the union of the repressor, it gets inactivated. This is a "repressible" operon.Which organelle makes energy for the animal cell?

Formed when caves can no longer support the dirt above it.
Answer:
Collapse dolines.
Explanation:
A doline is a special type of geological depression characteristic of karst reliefs. These reliefs are formed by the chemical weathering of rocks made of minerals that are soluble in water. In general, dolines are found in places where rocks are composed of limestone and clay in different proportions. When the calcium carbonate of limestone gets in contact with the rainwater, turns into calcium bicarbonate, which is soluble in the presence of water. Clay then deposits in lower areas originating the dolines or depressions.
Dolines might be formed by dissolution (the soil is dissolved in pluvial water that first flood and then infiltrate) or by collapsing. Collapse dolines occur because first, soluble material in lower layers formes a cavity underground. Soluble material flow to lower areas making a place to a cavity or hole under the ground. It gets bigger with time as the material in the bottom keeps being removed. It reaches a point in which the cave can no longer support the roof material, such as rocks, soil, and vegetables, and ends collapsing.

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared. Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally. This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered. Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you....!!!!!!
