The prevalence of the allele for sickle cell anemia in some populations is an example of?
"Balanced polymorphism" is demonstrated by the frequency of the trait for sickle cell anemia in various groups.
Why sickle cell anemia is called a Balanced polymorphism?
When individuals who possess two sets of the normal form gene have no benefit over heterozygous individuals, an illness might continue to be widespread. Balanced polymorphism would be at play when carriers have benefits that enable a harmful allele to survive in a community. This kind of polymorphism frequently involves heterozygosity for a hereditary disease that confers resistance to an infectious disease.
Sickle Cell Disorder
Anemia, joint discomfort, a huge spleen, and frequent, serious infections are all symptoms of the autosomal recessive illness sickle cell disease. Because carriers are immune to malaria, a parasitic ailment caused by Plasmodium falciparum that induces periods of cold and temperature, it serves as an example of balanced polymorphism.

What is the effect of each of the 4 types of inhibitors on the initial rate of an enzyme catalyzed reaction?
They are competitive inhibition, non-competitive inhibition, uncompetitive inhibition, and mixed inhibition are the 4 types of enzyme inhibition.
competitive inhibition: The enzyme's active site is occupied by a molecule other than the substrate, which results in competitive inhibition. The substrate and the inhibitor (molecule) are structurally and chemically related (hence able to bind to the active site). The competitive inhibitor blocks the active site to prevent substrate binding.In non-competitive inhibition, a substance binds to a site different from the active site (an allosteric site). The enzyme's active site changes structurally when the inhibitor binds to the allosteric site. This modification alters the affinity between the active site and substrate, prohibiting substrate binding. In non-competitive inhibition, the inhibitor only binds to the substrate-enzyme complex.Uncompetitive inhibition is frequent in reactions involving two or more substrates or products.Mixed inhibition: When an inhibitor binds both the enzyme by itself and the enzyme-substrate complex, mixed inhibition occurs. According to this scenario, the inhibitor may bind the enzyme by itself 60% of the time and the enzyme-substrate complex 40% of the time.learn more about enzyme inhibition here: https://brainly.com/question/14944549

Sympathetic stimulation results in what effects in the kidney?
Renal vascular resistance, renin release, and tubular salt reabsorption are all increased when sympathetic nerves to the kidney are active.
Sympathetic stimulation :The sympathetic nervous system alters the cardiac output, peripheral vascular resistance, and renal function, all of which play significant roles in controlling arterial pressure under various circumstances. The system has a role in the pathogenesis of chronic arterial hypertension and is capable of significant acute pressor effects. Because of its limitless capacity to restore altered arterial pressure to its original level by increasing or decreasing water and electrolyte excretion in response to elevated or decreased systemic arterial pressure, the renal volume/pressure control system is regarded as dominating physiological long-term arterial pressure regulation.
Renal vascular resistance, renin release, and tubular salt reabsorption are all increased when sympathetic nerves to the kidney are active. By reversing the pressure-natriuresis curve, these acts contribute to long-term increases in arterial pressure. Renal sensory receptors provide signals that are transmitted by renal afferent neurons to the efferent sympathetic nervous system, which has an impact on the control of arterial pressure. The current paper's goal is to examine recent research that shows how the sympathetic nervous system and the kidneys interact in the pathophysiology of both experimental and real-world arterial hypertension.

Describe the structure and function of mirna, snrna, and lncrna, which represent the three major types of noncoding rnas. What are four mechanisms by which lncrna molecules are thought to regulate cellular processes?.
Structure and function of miRNA:
A microRNA (abbreviated miRNA) is a small single-stranded non-coding RNA molecule, containing about 22 nucleotides found in plants, animals and some viruses, that functions in RNA silencing and post-transcriptional regulation of gene expression. miRNAs function via base-pairing with complementary sequences within mRNA molecules. As a result, these mRNA molecules are silenced, by one or more of the following processes: cleavage of the mRNA strand into two pieces, destabilization of the mRNA through shortening of its poly(A) tail, and less efficient translation of the mRNA into proteins by ribosomes.Structure and function of snRNA:
Small nuclear RNA (snRNA) is a class of small RNA molecules that are found within the splicing speckles and Cajal bodies of the cell nucleus in eukaryotic cells. The length of an average snRNA is approximately 150 nucleotides. They are transcribed by either RNA polymerase II or RNA polymerase III.Their primary function is in the processing of pre-messenger RNA (hnRNA) in the nucleus. They have also been shown to aid in the regulation of transcription factors (7SK RNA) or RNA polymerase II (B2 RNA), and maintaining the telomeres. snRNA are always associated with a set of specific proteins, and the complexes are referred to as small nuclear ribonucleoproteins, snRNP, often pronounced "snurps". Each snRNP particle is composed of a snRNA component and several snRNP-specific proteins.Structure and function of lncRNA?
Long non-coding RNAs (long ncRNAs, lncRNA) are a type of RNA, generally defined as transcripts more than 200 nucleotides that are not translated into protein. This arbitrary limit distinguishes long ncRNAs from small non-coding RNAs, such as microRNAs (miRNAs), small interfering RNAs (siRNAs), Piwi-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs), and other short RNAs. Long intervening/intergenic noncoding RNAs (lincRNAs) are sequences of lncRNA which do not overlap protein-coding genes.Four mechanisms by which lncRNAs molecules are thought to regulate cellular processes are:
The majority of lncRNAs are transcribed by RNA polymerase II, as evidenced by PoI-I occupancy, 5‘ caps, histone modifications associated with Pol-II transcriptional elongation, and polyadenylation.lncRNAs play a key regulatory role in the p53 transcriptional response. One of the direct p53 targets in response to DNA damage, a lncRNA called linc-p21 located upstream of CDKN1A gene, was found to act as a transcriptional repressor in the canonical p53 pathway and to play a role in triggering apoptosis. p53 regulates linc-p21 by directly inducing its expression, likely through direct binding to the linc-p21 promoter, while reduction of lincRNA-p21 increases expression of numerous p53-repressed transcripts.Pluripotency-associated lincRNAs were initially discovered in mouse embryonic stem cells. Somatic cell reprogramming to induced pluripotent stem cells (iPSCs) is accompanied by enriched expression of large intergenic non-coding RNAs (lincRNAs).The phenomenon of combinatorial transcriptional regulation by lncRNAs is also found in plants. The transition from vegetative to reproductive development is a highly regulated process that, in many plant species, is sensitive to environmental cues that provide seasonal information to initiate flowering during optimal times of the year.To learn more about lncRNA:

Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants. One rain forest plant species has a genetic variation that affects its leaf structure. The traits and the descriptions of the plant’s leaves are listed in the chart.
Description
Trait A: medium-tip leaves Leaves are narrower toward the tips, but don't come to a full point. Most of the water drains from the leaves.
Trait B: drip-tip leaves Leaves come to a sharp point, leading to thorough water drainage from the leaves.
Trait C: wide-tip leaves Water runs onto the leaves and tends to pool in pockets at the tips.
During natural selection, organisms with harmful traits are less likely to successfully reproduce than organisms with beneficial traits. Neutral traits don’t improve or hurt an organism’s chances for survival. So, they tend to persist in populations when environmental conditions are stable. If the environment changes, neutral traits could become harmful or beneficial depending on the situation.
In year 1, a population of rain forest plants has the following distribution: 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves. You will simulate three years of this population: year 1, year 5, and year 10. How will the trait distribution most likely change over this time?
The trait distribution most likely change over this time such that the plants with favorable traits, medium-tip leaves and drip-tip leaves will survive due to natural selection.
What is natural selection?Natural selection is the process by which organisms which are better suited to their environment survive whereas those not suited die off.
The organisms that are suited to their environment possess special features which enable them to adapt to changes in their environment.
Considering the plants in the rainforest with different leaf tips:
Trait A: medium-tip leavesTrait B: drip-tip leavesTrait C: wide-tip leavesSince fungi grow in moist environments, it can be seen that plants with Trait C will be least favored to survive, while plants with Trait B will be most favored to survive by natural selection.
Thus;
In year 1: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves.In year 5: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 0 % have drip-tip leavesIn year 10: the composition of plants is 25% have medium-tip leaves, 75% have wide-tip leaves, and 0% have drip-tip leaves.In conclusion, plants with favorable traits will survive due to natural selection.

What is transcription and translation?Transcription is the name given to the formation of RNA from a strand of DNA, with the “copy” of the information contained in the DNA to the RNA. This process is extremely important, as the information transcribed to the RNA molecule is translated into the formation of proteins.
Protein synthesis (translation) takes place in the cytoplasm and consists of reading the mRNA. The process involves three steps known as: initiation, elongation and termination. Synthesis begins (initiation step) when the smaller subunit of a ribosome and a specific tRNA associate with an mRNA.
With this information, we can conclude that Transcription is the formation of RNA from a strand of DNA, with the “copying” of the information contained in the DNA to the RNA.

What are Bacterial Plasmids?Plasmids are the little DNA rings that your bacterial self was stealing. Plasmids are specifically non-essential, extrachromosomal DNA fragments. What does that exactly mean? A plasmid is a brief, typically circular, double-stranded DNA fragment that is located outside of the main bacterial chromosome in the b.
Between 5 to 100 genes that are not necessary for the survival of the bacteria are typically found in plasmids.

What effect did decreasing the extracellular sodium have on the resting membrane potential?
Decreasing the extracellular sodium makes the resting membrane potential disappear. It tends to become less negative. Only a minute change is seen because the resting neuron is not very permeable to sodium.
Sodium is a soft silvery-white metal in nature. In the nerve cells, Sodium (Na+) is critical for the action potential. Action potentials are recursively initiated as the extracellular concentration of Sodium ion Na+ is modified. As the quantity of sodium in the extracellular solution is decreased its action potential decreases as well. Therefore, the quantity of sodium is inversely proportional to its action potential.
