15. what is the difference in emphasis between the terms cerebral asymmetry, hemispheric specialization, cerebral dominance and lateralization of function?
Answers
The distinctions between the words cerebral asymmetry, hemispheric specialization, cerebral dominance, and lateralization of function are as follows:
- cerebral dominance: one side rules over the other
- cerebral asymmetry: differences between the two cerebrums
- hemispheric specialization: different parts of the brain are specialized in different functions
- cerebral lateralization: tendency for some cognitive functions to be specialized to one hemisphere over the other
What does the words cerebral asymmetry, hemispheric specialization, cerebral dominance and lateralization of function meancerebral asymmetries are disparities in the anatomical and functional makeup of the two hemispheres of the brain. Cerebral lateralization is the propensity for some cognitive tasks to be specialized to one hemisphere over the other.
Hemispheric specialization describes how the left or right brain plays a distinct role in handling a certain neural job or behavior. Because of certain anatomical and/or computational traits, one hemisphere may be inclined to assume a role.
the cerebral cortex's or cerebrum's influence over lower brain areas. 2. the directive or disproportionate influence on certain aspects of behavior by one cerebral hemisphere (e.g., language is typically left lateralized in right-handed people).
Lateralisation is the idea that the two halves of the brain are functionally different and that each hemisphere has functional specialisation, e.g. the left is dominant for language, and the right excels at visual motor tasks.

Three-spine sticklebacks are small fish that originated in the ocean and continue to exist there, but then some took up residence in hundreds of streams and freshwater lakes in the northern hemisphere. Would you expect to find different species in lakes today?.
Answers
Yes, we expect to find different species in lakes today where Three-spine sticklebacks reside in streams and freshwater lakes in the northern hemisphere. The Three-spine stickleback (Gasterosteus aculeatus) is a small fish that originally evolved in the ocean but now inhabits hundreds of freshwater streams and lakes across the northern hemisphere.
These freshwater populations are usually characterized by a simplified pelvic skeleton, a loss of armor plates, a reduction in body size, and an increase in the number of breeding spines in males. Since sticklebacks have been living in freshwater for over 10,000 years, their adaptation has resulted in the development of new characteristics and new subspecies. The variety of subspecies that can be found in different freshwater locations is a result of adaptation to local environmental conditions. These adaptations are particularly pronounced in sticklebacks because they are present in so many different environments.
They can, for example, result in variations in body size, the number of breeding spines on males, or the shape of jaws. The development of different species is highly dependent on the isolation of populations and the unique environmental conditions that they face. This can cause genetically isolated populations to evolve in their own direction, resulting in different species, even in the same body of water. The differences that have arisen among the numerous freshwater populations have made them interesting research subjects. They have assisted us in gaining a better knowledge of how adaptations occur in nature and how new species are formed.

Answers
A woman who is type AB and a man who is type O have a child who is type AB. The answer to this question is yes, there is still a reason to get a paternity test despite the fact that the child is of type AB.
This is due to the fact that in this scenario, the child's blood type may have been inherited from either of its parents as they possess the alleles for both A and B blood types. Nonetheless, type O individuals only possess the O allele.The father’s biological makeup will indicate which allele the child inherited. A paternity test can be used to determine if the man is the child's biological father or if there may have been some sort of error.The rules of genetics state that every human has two alleles of the ABO blood type, one from each parent. The possible combinations are AO, BO, AB, and OO. The reason that the paternity test is required is that the child can be AB only if the mother has an AB gene and the father has either an A or B gene. It is critical to obtain a paternity test to verify that the man is indeed the biological father of the child.

Some cars are hybrid automobiles most automobiles are powered only by gasoline engines, and a few are powered by electric motors. In a hybrid automobile, there are two sources of power: a gasoline engine and an electric motor. Give an example of a trait that Mendel studied in hybrids.
Answers
One example of a trait that Mendel studied in hybrids is flower color in pea plants.
Gregor Mendel, known as the father of modern genetics, conducted extensive experiments with pea plants in the mid-19th century. He studied the inheritance patterns of various traits, including flower color, in these plants.
Pea plants have different variants for flower color, such as purple and white. Mendel discovered that certain traits are inherited in a predictable manner, and he used hybrids to study these patterns.
In the case of flower color, Mendel crossed pea plants with purple flowers (genotype PP) with pea plants with white flowers (genotype pp).
The resulting hybrids, known as the first filial generation (F1), all had purple flowers. However, when these F1 hybrids were self-fertilized or crossed with other F1 hybrids, Mendel observed a 3:1 ratio of purple to white flowers in the second filial generation (F2).
This indicated that the trait for flower color followed a specific pattern of inheritance, later known as Mendelian inheritance.
By studying traits like flower color in hybrids, Mendel was able to establish the fundamental principles of inheritance, providing the basis for modern genetics.

Imagine an animal that shows two variants; one long-legged and one short-legged. Each female produces 2 female offspring per generation and then dies. The offspring of the long-legged ones survive to adulthood (reproductive age) with a probability of 55% and the offspring of the short-legged ones survive to adulthood with a probability of 45%. If you begin with a population of 60 females of each type, what proportion of individuals will have long legs in 5 generations?
Answers
The proportion of individuals with long legs in the fifth generation is 43.92/(43.92+19.67)= 0.69The proportion of individuals with long legs in the fifth generation is 0.69 or 69%. Hence, the correct option is 69%.
The Hardy-Weinberg principle is used to calculate the genotype and allele frequency in a population. This problem, however, is not about the Hardy-Weinberg principle but about population genetics.
So, Let's solve the problem now;Given:Each female produces 2 female offspring per generation and then dies.The offspring of the long-legged ones survive to adulthood (reproductive age) with a probability of 55% and the offspring of the short-legged ones survive to adulthood with a probability of 45%.If you begin with a population of 60 females of each type, we can calculate the number of individuals in the first generation.Number of long-legged individuals in the first generation= 60 * 0.5 = 30Number of short-legged individuals in the first generation = 60 - 30 = 30Now, we can calculate the number of individuals of the next generation using the given probabilities.
The number of long-legged individuals in the second generation = 30 * 0.55 * 2 = 33The number of short-legged individuals in the second generation = 30 * 0.45 * 2 = 27Similarly, we can calculate the number of individuals of the third, fourth and fifth generations as follows.Number of long-legged individuals in the third generation= 33 * 0.55 * 2 = 36.3Number of short-legged individuals in the third generation = 27 * 0.45 * 2 = 24.3Number of long-legged individuals in the fourth generation= 36.3 * 0.55 * 2 = 39.93Number of short-legged individuals in the fourth generation = 24.3 * 0.45 * 2 = 21.87
Number of long-legged individuals in the fifth generation= 39.93 * 0.55 * 2 = 43.92Number of short-legged individuals in the fifth generation = 21.87 * 0.45 * 2 = 19.67. Therefore, the proportion of individuals with long legs in the fifth generation is 43.92/(43.92+19.67)= 0.69The proportion of individuals with long legs in the fifth generation is 0.69 or 69%.

which of the following statements best describes the trp operon?
Answers
The trp operon is a genetic system found in bacteria that regulates the production of tryptophan. It consists of a promoter, operator, and several genes that code for enzymes involved in the biosynthesis of tryptophan. When tryptophan levels are low, the trp repressor protein is inactive and RNA polymerase can bind to the promoter, allowing transcription of the trp genes. However, when tryptophan levels are high, tryptophan binds to the trp repressor protein, causing it to become active and bind to the operator, preventing RNA polymerase from transcribing the trp genes. This negative feedback mechanism ensures that the bacteria only produce tryptophan when it is needed, conserving energy and resources. Overall, the trp operon is a well-studied example of gene regulation and has provided valuable insights into the mechanisms of gene expression.
The trp operon is best described as a cluster of genes involved in the biosynthesis of the amino acid tryptophan, which is regulated by a feedback inhibition mechanism. When tryptophan levels are low, the trp operon is activated, allowing for the production of enzymes necessary for tryptophan synthesis. Conversely, when tryptophan levels are high, the trp operon is repressed, halting the production of these enzymes. This regulation helps maintain appropriate intracellular tryptophan concentrations, ensuring efficient use of cellular resources.

Answers
Explanation:
Comparison
DNA
RNA
Full Name
Deoxyribonucleic Acid
Ribonucleic Acid
Function
DNA replicates and stores genetic information. It is a blueprint for all genetic information contained within an organism
RNA converts the genetic information contained within DNA to a format used to build proteins, and then moves it to ribosomal protein factories.
Structure
DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous base.
RNA only has one strand, but like DNA, is made up of nucleotides. RNA strands are shorter than DNA strands. RNA sometimes forms a secondary double helix structure, but only intermittently.
Length
DNA is a much longer polymer than RNA. A chromosome, for example, is a single, long DNA molecule, which would be several centimetres in length when unravelled.
RNA molecules are variable in length, but much shorter than long DNA polymers. A large RNA molecule might only be a few thousand base pairs long.
Sugar
The sugar in DNA is deoxyribose, which contains one less hydroxyl group than RNA’s ribose.
RNA contains ribose sugar molecules, without the hydroxyl modifications of deoxyribose.
Bases
The bases in DNA are Adenine (‘A’), Thymine (‘T’), Guanine (‘G’) and Cytosine (‘C’).
RNA shares Adenine (‘A’), Guanine (‘G’) and Cytosine (‘C’) with DNA, but contains Uracil (‘U’) rather than Thymine.
Base Pairs
Adenine and Thymine pair (A-T)
Cytosine and Guanine pair (C-G)
Adenine and Uracil pair (A-U)
Cytosine and Guanine pair (C-G)
Location
DNA is found in the nucleus, with a small amount of DNA also present in mitochondria.
RNA forms in the nucleolus, and then moves to specialised regions of the cytoplasm depending on the type of RNA formed.
ReactivityDue to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe.RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions. RNA’s larger helical grooves mean it is more easily subject to attack by enzymes.Ultraviolet (UV) SensitivityDNA is vulnerable to damage by ultraviolet light. RNA is more resistant to damage from UV light than DNA.
