Inorganic nitrogen is initially assimilated into the amino acid glutamine (option D).
What is inorgаnic nitrogen?Nitrogen аssimilаtion is the process by which inorgаnic nitrogen compounds аre used to form orgаnic nitrogen compounds such аs аmino аcids, аmides, etc. Plаnts аnd other orgаnisms, which cаnnot utilise nitrogen molecules directly, depend on the аbsorption of nitrogen аs nitrаtes or аmmoniа.
Thus, nitrogen аssimilаtion is а vitаl process controlling plаnt growth аnd development. Inorgаnic nitrogen is аssimilаted into the аmino аcids glutаmine, glutаmаte, аspаrаgine, аnd аspаrtаte, which serve аs importаnt nitrogen cаrriers in plаnts. Glutаmine synthetаse аssimilаtes аmmonium into аmino аcids, thus it is а key enzyme for nitrogen metаbolism. The cytosolic isoenzymes of glutаmine synthetаse аssimilаte аmmonium derived from primаry nitrogen uptаke аnd from vаrious internаl nitrogen recycling pаthwаys.

The prototype approach assumes that stimuli are classified into different concepts based on features that are ________.
The prototype approach assumes that stimuli are classified into different concepts based on features that are set of entities within the category that represent a prototypical member.
The acquisition of a prototypical representation of a category through some sort of abstraction process, according to prototype theory, is how categorization is accomplished. According to Posner (1969) and Neumann (1977), the prototypical representation is thought to be a summary representation that represents the "central tendency" of all the examples that have been encountered. Then, new examples can be categorized according to how closely they resemble this "best example." Think about what happens when someone is asked to envision a category like "tree," for instance.

Which trophic levels would be impacted by lower yields of fungi (mushrooms) due to, for example, acid rain?
Fungi belong to the decomposer topic level because they decompose organic matter and return the elements to the producer for reuse. Therefore, if mushrooms have low yields, less material to break down, and fewer minerals are available to them, they will be directly affected.
It also indirectly affects everything above the nutritional stage, which depends on the producer.
Another nutritional stage, the decomposer or transformer, is composed of organisms such as bacteria and fungi that break down dead organisms and waste into nutrients that the producer can use.
The decomposer forms the final trophy level. When living things produce waste or die, inanimate objects remain. Nutrients and organic matter are trapped in this substance. Decomposers like fungi break down waste and return it to raw nutrients.
In a system of five trophic levels, organisms are classified according to their lifestyle. The five levels include primary producers (plants), primary consumers (herbivores), secondary consumers, tertiary consumers, and detritivores (decomposers).

The initiating event in the development of nephrotic syndrome is a derangement in the glomerular membrane that causes increased permeability to which substance
The initiating event in the development of nephrotic syndrome is a derangement in the glomerular membrane that causes increased permeability to plasma proteins.
Nephrotic syndrome can be understood as a kidney disorder in which the glomeruli filter of the kidney gets damaged due to which it is unable to filter the proteins and passes an excess amount of protein in the urine.
Glomeruli filter consists of clusters of small blood vessels in the kidneys that function in filtering the waste and excess water from the blood. It also sweeps the blood protein which is necessary to maintain the correct amount of fluid in the body, from seeping into the urine. But when it gets damaged glomeruli stop sweeping the protein from the urine as a result too much blood protein leaves your body, leading to nephrotic syndrome.

Stubble bristles (Sb) is dominant to wildtype bristles (Sb+) in Drosophila melanogaster. In a population where there are 137 flies with wildtype bristles and 836 flies with stubble bristles, what are the allele frequencies for the Sb and Sb+ alleles (assuming the population is in Hardy-Weinberg equilibrium)? Please calculated your answers to 3 decimal places.
f(Sb)=
f(Sb+)=
If the population is in Hardy-Weinberg equilibrium, what proportion of the population would you expect to be heterozygous?
Populations in H-W equilibrium have the same allelic and genotypic frequencies generation after generation. f(Sb) = p = 0.626. f(Sb+) = q = 0.374. F(SbSb+) = 2pq = 0.468
What is Hardy-Weinberg Equilibrium?
The Hardy-Weinberg equilibrium is a theory that states that, assuming a diallelic gene,
⇒ The allelic frequencies in a locus are represented as p and q.
• The frequency of the dominant allele p(X) is p
• The frequency of the recessive allele p(x) is q
⇒ The genotypic frequencies after one generation are
• p² (Homozygous dominant genotypic frequency),
• 2pq (Heterozygous genotypic frequency),
• q² (Homozygous recessive genotypic frequency).
Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium.
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Sb is dominantSb+ is recessive ⇒ wild typePopulation size ⇒ 137 + 836 = 973Individuals with wildtype bristles ⇒ 137 ⇒ Sb+Sb+Individuals with stubble bristles ⇒ 836 ⇒ SbSb and SbSb+First, we will get the frequencies.
To do it, we will use the number of individuals. These values will tell us about phenotypic frequencies,
Phenotypic frequency
F(wildtype) = q² = 137/973 = 0.14F(stubble) = p² + 2pq = 836/973 = 0.86Now, we will use the frequency of the recessive phenotype to get its genotypic and allelic frequencies.
F(Sb+Sb+) = q² = 137/973 = 0.14 ⇒ Recessive Genotypic frequency
f(Sb+) = q = √0.14 = 0.374 ⇒ Recessive Allelic frequency
Now, Since this population is in H-W equilibrium, we will use q (recessive allelic frequency) to get the dominant allelic frequency and the dominant genotypic frequency. To do it, we will clear the following equation,
p + q = 1
p + 0.374 = 1
p = 1 - 0.374
p = 0.626 ⇒ Dominant Allelic frequency
F( SbSb) = p² = 0.626² = 0.392 ⇒ Dominant Genotypic frequency
Finally, we will get the heterozygous frequency. There are two options,
To susbtract the dominant genotypic frequency to the dominant phenotpic frequency,F(SbSb + SbSb+) - F(SbSb) = 0.86 - 0.392 = 0.468
To clear the following equation,p² + 2pq + q² = 1
0.392 + 2pq + 0.14 = 1
2pq = 1 - 0.392 - 0.14
2pq = 0.468
Answers:
- f(Sb) = p = 0.626 ⇒ Dominant Allelic frequency
- f(Sb+) = q = 0.374 ⇒ Recessive Allelic frequency
- F(SbSb+) = 2pq = 0.468 ⇒ Heterozygous frequency
