The answer is the Al2O3 compound we have to predict - to have the highest melting point.

A substance that contains ions will eventually have a higher melting point. The stronger they are held together, the smaller they are and the closer they are to one another, the bigger the charge. They are held collectively. We were supposed to be concentrating on those interesting atomic interactions, which would result in aluminum oxide having the highest melting point.

One of the most prevalent metals in the crust of the planet is aluminum. Cookware, industrial applications, building, transportation, and aerospace are just a few of its many uses. Key characteristics are its capacity to withstand corrosion and be reprocessed. An important physical characteristic is the melting point of aluminum, or any other material, for that matter. Knowing aluminum's melting point aids in locating any metal impurities or other unidentified substances.

The melting point can also be used to determine the metal's general purity. If aluminum has a wide melting range when recycled, it contains more impurities. The purity of the substance increases as the melting point range decreases.

The receivables turnover ratio in year 2 to year 2 is 4.86.

Receivables turnover is the ratio used to measure how long it takes to collect receivables during one period or how many times the funds used in these receivables rotate in one period. Receivables turnover rate is measured by comparing credit sales with the average receivables

Accounts receivable turnover is calculated by the following formula:

Average account receipts = (initial receipts + final receipts)/2

Average account receipts = (88000 + 80000)/2 = 168000/2 = 84000

Accounts Receivable Turnover = net sales/average account recoverable

In eukaryotic cells, gene expression is regulated at the epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels.

Gene expression in eukaryotic cells is controlled by both repressors and transcriptional activators. Eukaryotic repressors, like their prokaryotic counterparts, bind to specific DNA sequences and inhibit transcription.

Eukaryotic cells, unlike prokaryotic cells, can regulate gene expression at multiple levels. Control of access to the DNA is the first step in eukaryotic gene expression. This type of regulation, known as epigenetic regulation, occurs even before transcription begins.

In both prokaryotic and eukaryotic cells, sequence-specific transcription factors are regarded as the most important and diverse mechanisms of gene regulation. Controlling transcriptional initiation is a primary way for eukaryotic organisms to regulate gene expression. Most eukaryotic genes are transcribed by proteins (trans-acting factors) that interact with specific gene sequences (cis-acting regulatory sequences).

The electrical potential on the two sides of the cell membrane of the neuron differs when it is at rest.

Through the release of potassium from the cell and an inward flux of sodium through particular voltage-dependent ion channels, a stimulus causes depolarization of the neuron. The resulting neurological signal, known as an action potential, travels along the axon like a wave. The synapse might be seen as a break between two neurons or as a connection between a neuron and a muscle. So, the presynaptic terminal/membrane, synaptic cleft/gap, and postsynaptic terminal/membrane make up the synapse. ACh is released from the presynaptic terminal's vesicles into the synaptic cleft in response to an impulse, making contact with the cholinergic receptors on the postsynaptic membrane.

Fraction of butterflies have a homozygous dominant phenotype is 13/100 or 13%.

The Hardy-Weinberg principle states that allele and genotype frequencies in populations remain constant even in the absence of evolutionary mechanisms. Ultimately, the Hardy-Weinberg principle models populations without evolution under the following conditions: No mutation. No Immigration.

p² + 2pq + q² = 0

Where, p² = frequency of dominant (BB) allele

q² = frequency of recessive (bb) allele

2pq = frequency of heterozygous dominant (bb) allele

For the given question:

Since white is recessive (bb), and 40% of the butterflies are white, then bb = q² = 0.4.

To determine q,

which is the frequency of the recessive allele = q²

A salt solution is required to extract protein X from the membrane; therefore, it is an amphitropic membrane protein that is reversibly attached to the membrane.

The correct choice is C.

This problem states that proteins can be isolated from the red blood cell membrane using a concentrated salt solution. This is the actual clue to the answer. In general, the proteins that are usually found associated with the cell membrane are integral membrane proteins.  This means the protein remains deep within the cell membrane, containing the two cell membrane bilayers. Due to this relationship, integral membrane proteins are very difficult to isolate and cannot be isolated by conventional techniques. The technique developed to isolate proteins is called Freeze fracture.

But only a simple saline solution will help here. This method of protein isolation is very common when the protein has many ionic side chains. With this in mind, the type of membrane protein to consider is an amphitropic protein.

Amphitropic proteins are proteins that have an affinity for cell membrane lipids and aqueous media and remain loosely bound to the membrane through ionic interactions. When salt is used, the ionic salt breaks the hydration shell around the protein-containing groups and removes the charge density above the protein, causing it to decompose and thereby isolate it.
