The protein thorain is encoded by the gene thrL, and thorain is a negative regulator of the thrMN operon. Assume there is no other regulation taking place. Predict the phenotype of a thrL- mutant that encodes a nonfunctional thrL protein.
a. The thrM and thrN genes would be transcribed at higher levels compared to non-mutant.
b. The thrM and thrN genes would be transcribed all lower levels compared to non-mutant.
c. The thrM and thrN genes would not be transcribed
Answer:
The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.
Explanation:
Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.
With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.

Darwin's ideas espoused in both Origin of Species and The Descent of Man were incompatible with the prevalent scientific racism of the age (like that of Robert Knox, for example) because of Darwin's emphasis on _______.
Answer:
The correct answer is "change".
Explanation:
The missing options of this question are:
A. natural selection.
B. immutability.
C. survival of the fittest.
D. change.
The correct answer is option D. "change".
The scientific racism that was prevalent during Charles Darwin books publications was related to the concept of "pure races", and the association of the inheritance of the "superior attributes" related to these races. Darwin's ideas were incompatible to this scientific racism, since Charle Darwin theories support the idea of a constant change among all people attributes, produced by genetics behavior and exposure to environmental factors.

What is the ecological relationship between the monk seal and the octopus/eel/triggerfish?
Answer:
The monk seal and the octopus/eel/triggerfish also live in close proximity to each other and have an ecological relationship between them. The monk seals are the predators to octopus/eel/triggerfish in the ocean.
The monk seal preys on octopus/eel/triggerfish in the ocean for their survival and competes with sharks and other marine animals for food.
Hence, the monk seal and the octopus/eel/triggerfish have ecological relationship of the predation in which one animal feed on another.
The ecological relationship between the monk seal and the octopus/eel/triggerfish - predator and prey.
The monk seals are seals with no ear and are found in the tropic climate.
These are the organisms that are live in close proximity to the octopus/eel/triggerfish.The seals are the predators to eels, triggerfish and octopuses at the bottoms of the ocean floor.Sharks are present in the same habitat and feed on the same organisms so they are in competition.Thus, the ecological relationship between the monk seal and the octopus/eel/triggerfish - predator and prey.

The plasma membrane represents an energetic barrier to the free diffusion of ions from the extracellular space into the cytoplasm. Why are molecules such as valinomycin effective at transporting ions across the membrane? Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
Answer:
Why are molecules such as valinomycin effective at transporting ions across the membrane?
Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.
Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.
Explanation:
Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
You are now taking a ride on the Magic School Bus with Ms. Frizzle. This bus is magic because it can go anywhere within the body. Today’s lesson is on Central Dogma. Ms. Frizzle takes your class directly to the nucleus to start your field trip. Since this trip is about the central dogma, what three major cellular process will be involved? Where will you bus be going within the cell during each of these processes? For each process, describe in your own words and in general what is going on?
Answer:
See the answer below
Explanation:
The trip will involve a bit of stoppage inside the nucleus during which replication and transcription will take place before proceeding to the cytoplasm where synthesized mRNA will become translated into protein.
The central dogma refers to a series of processes during which genetic information in the DNA of a cell is encoded and expressed in living cells. The 3 major steps involved in these processes are:
1. Replication
2. Transcription
3. Translation
Replication involves the synthesis of a double-stranded DNA molecule from a template of another double-stranded DNA molecule within the nucleus. In order words, replication is a process during which a DNA molecule reproduces itself. Each of the strands of the DNA acts as a template for the synthesis of another new strand. Eventually, 2 new double-strand DNA molecules are formed each consisting of one old strand and one new strand.
During transcription, the information contained in deoxyribonucleic acids is encoded and transcribed into another molecule known as the messenger ribonucleic acid. This process happens in the nucleus of the cell.
After transcription and processing of the mRNA produced, the resulting mRNA is then transported to the cytoplasm where, together with the ribosome and transfer RNA, the encoded information becomes translated into protein. Each of the genetic codes in the mRNA is translated to their respective amino acids and the amino acids are linked together by peptide bonds to form a protein.
Que son las células procariotas?
Answer:
En biología, con el término procariotas se hace referencia a las células que no tienen un núcleo formado, en contraste con las células que han formado un núcleo, las células eucariotas.
Estas células tienen una estructura más simple que las células eucariotas y son de menor tamaño. Externamente, las células procariotas están separadas del medio ambiente por la membrana celular, pero internamente no tienen ninguna otra formación. En su mayor parte, los organismos procariotas son unicelulares y pertenecen al grupo de bacterias.
What is a substrate? a molecule that acts as a catalyst a place where the reaction occurs a place on the product where the enzyme fits a reactant that is catalyzed by an enzyme
Answer:
a reactant that is catalyzed by an enzyme
Explanation:
Reactants are often referrred to as substrates as those are what enzymes mostly act upon to create products or some desired consequence
Option (d). a reactant that is catalyzed by an enzyme is called the substrate.
SubstrateA substrate exists as a molecule on which an enzyme acts. Enzymes catalyze chemical reactions that concern substrate, where the substrate binds to the enzyme's active site, and an enzyme-substrate complex is created. By action of the enzyme, the substrate exists transformed into a product, released from the active site, and free to obtain another substrate.
Enzyme catalysis exists as the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes exist in proteins, and most such processes are chemical reactions. Within the enzyme, naturally, catalysis happens at a localized site, called the active site.
The reactant in an enzyme-catalyzed reaction is named a substrate.
Because enzymes can expand reaction rates by enormous factors (up to 1017 times the uncatalyzed rate) and tend to be very precise, typically producing only a single product in quantitative yield, they exist the focus of active research.
Hence, Option (d). a reactant that is catalyzed by an enzyme is called the substrate.

The functions of the oral cavity include all of the following, except:_________a. mechanical processing of food. b. digestion of carbohydrates. c. analysis of material before swallowing. d. lubrication. e. absorption of monosaccharides.
Answer:
e. absorption of monosaccharides
Explanation:
The oral cavity is the first part of the digestive system where food is received, crushed, mixed with digestive enzymes secreted at that level, and also where the food is turned into the form of bolus before it is being channeled down through the pharynx into the alimentary canal for further digestion.
The oral cavity is also a site for respiration and speech production.
It is made up of the teeth, hard and soft palate, tongue and other vital parts that play different roles in food digestion.
The function of the oral cavity does not include absorption monosaccharides.
A particular protein (Vac8) found in yeast has this N-terminal sequence, Met-Gly-Ser-Ser-Cys.... The corresponding DNA sequence in the coding strand is 5' ATG GGC TCA TCG TGC.... If the DNA sequence is mutated to 5' CTG GGC TCA TCG TGC..., what will happen to this VAC8 gene? (in RNA, CUG codes for Leu)
Answer:
The protein will not be synthesized because this point mutation produces the loss of the start codon (substitution of Met by Leu).
Explanation:
The mutations are changes in the DNA sequence that have diverse effects on protein synthesis. A mutation in the start AUG codon may lead to the reduction and even the elimination of protein synthesis. In consequence, this type of point mutation is usually referred to as 'start-loss mutation'.

Besides the HCT, what other component of blood could be measured to give a better understanding of oxygen-carrying capacity? Explain your answer.
Answer:
The haemoglobin levels or counts can be used.
Explanation:
The oxygen carrying pigment of the blood is the heamoglobin (Hb).it is a protein molecule with for heam groups,Each of the latter can bind with 4 molecules of oxygen in a cooperate bonding.The more oxygen molecules binding by Hb,the more oxygen is carry in RBC.
Therefore if the number of Hb counts is reduced in an individual the volume of oxygen in the RBC of the subject should reduced,Therefore, this should be a good indicator of the lower oxygen capacity of the blood of the individual.
Basically in a physiological female the Hb count/100ml of blood is 12-16g/ml,like wise 13-18g/100mI in a physiological man.
Therefore fluctuations in the levels of these values below the set points is an indicator of distortion in the oxygen carrying capacity of the blood.
The amount of the blood in volume that contains RBC is called Hematocrit. Therefore for accuracy the HCT together with the Hb counts are good indicators of oxygen capacity of the blood.
Hematocrit refers to the volume percentage of the red blood cells in the blood. Oxygen-carrying capacity can be measured by several techniques.
The co-oximetry and Arterial Blood Gas can be used to determine the oxygen-carrying capacity.
The techniques can be explained as:
Co-oximetry is a type of blood test used to measure the oxygen-carrying capacity of the hemoglobin in the blood. The test uses the light of different wavelengths that can pass through the blood to determine oxygen capacity. Arterial blood gas or ABG test is a type of blood test used to measure the pH and oxygen-carrying capacity of the blood present in the artery. It is used to determine the efficiency of the lungs to exchange the gas oxygen and carbon dioxide from the blood.
Thus, the co-oximetry and ABG test can be used to determine oxygen levels in the blood.

A haploid species has a gene on chromosome 2 which codes for lactase. In nature, four different alleles of the lactase gene have been identified. How many different alleles could you find in the genome of a single individual of this species
Answer:
Haploid organisms have only one allele per locus
Explanation:
In haploid species, the number of alleles for a single locus always will be only one. Haploid species contain one complete set of chromosomes in their somatic cells. In nature, species are generally diploids but there are exceptions to this norm (e.g., male bees, ants and wasps are derived from an unfertilized egg). Consequently, in haploid organisms, the allelic and genotypic frequencies are the same. In this case, it is also important to note that the three remaining alleles will be distributed among the other haploid individuals in the population.
