20. Allosteric effectors: a. can cause large changes in enzymatic activity. b. can lead to a decrease in the availability of a protein. c. do not alter the sensitivity of a metabolic pathway. d. decrease the sensitivity of the enzyme at nearly all concentrations of substrate. e. alter enzyme activity by binding to the active site of an enzyme.
Answer:
a. can cause large changes in enzymatic activity.
Explanation:
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
Hence, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.

Which of the following statements about the process of science is accurate?
A. Science does not use evidence and data collected to advance our understanding of natural and supernatural phenomena.
B. Science attempts to solve a problem by evaluating the plausibility of only one solution without considering other possible explanations.
C. Science is a systematic method of procedures designed to answer questions by evaluating evidence.
D. Science can answer all questions regarding the human experience and personal values.
Answer:
C
Explanation:
The correct answer would be that science is a systematic method of procedures designed to answer questions by evaluating evidence.
Science is generally defined as man's way of obtaining knowledge about his natural environment through the evaluation of evidence available to him. Science follows a laydown procedure to obtain evidence through data collection, analyze such, and arrive at reasonable conclusions. This laydown procedure is referred to as the scientific method.
Hence, that science does not use evidence and data collected to advance the understanding of natural and supernatural phenomena is an antithesis to what science represents.
Science only arrive at conclusion after evaluating all available evidence associated with a phenomenon. That it attempts to solve a problem by evaluating the plausibility of only one solution without considering other possible explanations is, therefore, not true.
Science continuously seeks knowledge in order to understand the natural world. Hence, while science has been able to answer several questions about man and his natural world, several questions still have their answers pending. That science can answer all questions regarding the human experience and personal values is, therefore, far from being true.
The only accurate option that describes science is C.
The best description of science is that science is a systematic method of procedures designed to answer questions by evaluating evidence.
What is science?Science is defined as the process by which man obtain knowledge about his natural environment through observation and critical evaluation of facts and evidences in order to arrive at a conclusion.

Answer:
Incomplete dominance
Explanation:
In genetics, incomplete dominance refers to an inheritance mode in which two gene variants (i.e., alleles) of the same locus combine in a way that neither allele dominates the other. This phenomenon is similar to codominance, but in this last case, both alleles are dominant. Incomplete dominance produces a new phenotypic trait resulting from the combination of both non-dominant alleles. An example of incomplete dominance includes the pink color of snapdragons resulting from the cross of red-flowered snapdragons with white-flowered snapdragons.

An acoustic neuroma is a tumor that arises from neurolemmocytes surrounding the vestibular portion of the vestibulocochlear nerve. The tumor is benign, but generally grows within the confined space of the petrous part of the temporal bone, thus compressing the nerve and creating problems with balance and hearing loss. What other, nearby nerve would you expect to also be affected by this tumor
Answer: The nearby nerve that can be affected by this tumour is the FACIAL NERVE.
Explanation:
As stated in the question, the acoustic neuroma is a tumor that arises from the vestibular portion of the vestibulocochlear nerve which is the VIII ( 8th) cranial nerve.
VESTIBULOCOCHLEAR NERVE: These nerves are composed of two distinct sets of fibres, vestibular nerves and cochlear nerves.
The vestibular nerves arise from the semicircular canals of the inner ear and convey impulses to the cerebellum. They are associated with the maintenance of posture and balance. The cochlear nerves originate in the spiral organ in the inner ear and convey impulses to the hearing areas in the cerebral cortex where sound is perceived.
The Facial nerve, also called the 7th cranial nerve, which are the motor fibres that supply the muscles of facial expression. It lies adjacent to the vestibulocochlear nerve as they pass through the internal auditory canal which is located at the petrous part of the temporal bone. As the tumor grows, the facial nerve would be affected because it's the closest nerve to the VESTIBULOCOCHLEAR nerve..

As part of a forensic analysis, you have been asked to determine an individual's ancestry using skeletal indicators. The metric measurements you collect indicate that the individual is of European ancestry, but you see several nonmetric traits in the cranium that are typically found in individuals of Asian ancestry. Why might the two methods give different results
Answer:
Due to difference in the methods that is used for analysis.
Explanation:
The two methods give different results because we used two different types of measurements i. e. metric measurement and nonmetric traits. In the metric measurement, we calculate the quantitative character of an individual that gives information about the current status of an individual, while on the other hand, in non-metric traits refers to the method which is used to evaluate genetic connections within and between populations that were present in the past.

Fruit flies (Drosophila melanogaster) with a wild-type phenotype have gray bodies and red eyes. Certain mutations can cause changes to these traits. Mutant flies may have a black body and/or cinnabar eyes. To study the genetics of these traits, a researcher crossed a truebreeding wild-typed male fly with a true-breeding female fly with a black body and cinnabar eyes. All of the F1 progeny displayed a wild type phenotype. Which of the following is correct about the traits observed?a. Gray body and cinnabar eyes are dominant.b. Eye color is sex-linked.c. Body color is sex-linked.d. Gray body and red eyes are dominant.
Answer:
d
Explanation:
The correct answer would be that gray body and red eyes are dominant.
The wild type trait is represented by gray bodies and red eyes while the mutant trait is represented by black body and/or cinnabar eyes. A cross between the wild type and the mutant only yield F1 offspring with wild type phenotype. This, thus, means that the wild type trait is dominant while the mutant trait is recessive.
Since the wild type trait is depicted by gray body and red eyes, it means that the gray body and red eyes traits are dominant while the black body and cinnabar eyes are recessive.
The correct option is d.
