If a 10 year old child is diagnosed with acute glomerulonephritis and admitted to the pediatric unit, the nurse should TAKE THE VITAL SIGNS EVERY 4 HOURS AND OBTAIN THE DAILY WEIGHT OF THE CHILD.

Glomerulonephritis is a disease of kidney where the glomeruli are injured. It is very important to take measure the vital signs such as taking blood pressure of the child because in this disease acute renal failure might occur that hampers the vital functions of the body. Weighing the child everyday is also important because this helps to know the fluid status in the body.

What needs to happen for a solute to dissolve in a particular solvent? A. The attractions between the solute and solvent molecul
Masja [62]

The attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together. This needs to happen for a solute to dissolve in a particular solvent .

Answer: Option A

<u>Explanation:</u>

Solute means the substances which get dissolved by another one, Ex: salt. On the other hand, Solvent refers the substance which dissolves. Ex: Water. To get dissolved in solvent, the particles present in solute move away.

It is possible only when the attractive force between solute and solvent are greater than binding force of solute and solvent.  Separation and mixing up with solvent particles, in general, called as solvatation.

Answer:

In the past decade, genetic testing aimed at identifying ancestry has experienced exponential growth, with nearly 26 million tests sold since 2018 (6). Companies – such as 23andMe – offer kits to trace your genetic legacy and geographical origins using Y-chromosome, mitochondrial, and whole-genome markers (1). Genetic ancestry testing holds the potential to identify the geographic origins of an individual’s ancestors, ancestral lineages, and relatives, but does not define a deterministic cultural identity.

DNA located in the mitochondrion, mtDNA, is inherited maternally in both sexes and can thus provide evidence of an direct, unbroken female lineage (10). The mtDNA typically passes unchanged from mother to offspring, except in the rare case of a mutation. By comparing full mtDNA sequence or assaying for particular haplogroups, it is possible to establish both close ancestry and rough global origins, respectively (4). Regardless, two individuals, even with an exact mtDNA match, may have had an ancestor as far back as ten or sixteen generations (9). Consumers should thus be warned against over-interpreting mtDNA results since they unravel a single thread in an individual’s genetic ancestry. A distinct benefit of mtDNA tests is the ability to distinguish maternal lineage in recorded genealogical data in which females adopt the male surname (10).

Contrary to mtDNA, Y-chromosome DNA is inherited paternally, passed down from father to son. Ancestry tests analyze locations along the Y chromosome, cataloging mutations known as single nucleotide polymorphisms and repeating patterns known as short tandem repeats (8). Test results can determine if two male members of separate families with the same surname have a close genetic relationship (10). In addition, a multitude of haplogroups, representing branching in the Y-chromosome tree, can be used to examine the presence of a common ancestor thousands of years back, contributing another thread to the central question of genetic ancestry (8,7).

A more comprehensive basis of determining ancestry relies on the presence of millions of autosomal variants, such as single nucleotide variants (SNVs), across the genome (10,3,7). An individual’s unique pattern of SNVs is compared with various reference populations and other consumers in order to infer their ancestry (10). Companies such as 23andMe provide a readout of broad ancestry and specific subgroups. Ancestral populations such as European and Western Asian are often further broken down into subpopulations (e.g. British, Greek, Iran). The accuracy of more specific statistical inferences is often variable, with companies examining different SNVs reporting inconsistencies in percentages for the same individual (3). In addition, since many reference populations do not account for migration and interbreeding thousands of years back, an ethnicity estimate with a high degree of confidence could still differ drastically from an individual’s expectations (10). Statistical inferences have diminished accuracy in regions such as East Africa and South Asia with comparatively limited data relative to well studied European populations, leading to further possible inconsistencies (7).

While the commercialization of genetic-ancestry tests has resulted in improved accuracy and innovation, the hyper-aggressive marketing of such products risks misinforming consumers, particularly in regards to cultural heritage. Consider, for example, an advertisement by the company Ancestry where a woman finds “[her] strength” after realizing she shares maternal lineage to a matriarchal people in Ghana (11). The pervasive marketing has even infiltrated music: In 2018, Spotify and Ancestry partnered to suggest playlists and artists based on test results, blatantly equating DNA and cultural heritage (2). While such marketing efforts are externally harmless, they carry a hidden message that DNA plays a meaningful role in our cultural identity. Most consumers are ill-informed in the field of genomic science, and may assume that their test results are deterministic and connote a contribution to heritage.

Genetic-ancestry tests may also perpetuate the idea of innate racial differences and entangle race with culture. A randomized trial reported that White Americans with lower genetic literacy had increased essentialist views after receiving test results (6). Those of Hispanic heritage share cultural aspects such as language, but may differ in genetic test results due to post-colonial admixture of Native, European, and African populations (5). Does a test result of 90% European heritage indicate “more” Hispanic heritage than 80% African? Such conclusions are entirely inaccurate and dangerous, but plausible given the genetic literacy of the typical consumer.

What would happen if you delete one amino acid in a particular protein?
Karo-lina-s [1.5K]
It depends upon the protein and also where the deletion of the single amino acid has occurred. Does ur alter or disrupt an important fundamental function or aspect of the protein such as the capability of substrates to bind to the active site, or is near a region that is primarily for developing the additional structure of the protein and is not as important. In most cases, a single amino acid change will not cause the protein to lose its complete function of be denatured.
