Which statement below BEST summarizes the role of the DNA molecule in cells?

Answer:

helium

Explanation:

The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons.

Hope this helps.

Helium is an element that contain 2 protons, 1 neutron and 2 electrons.

Helium having two valence electrons and the electronic configuration 1s 2, the helium atom does not establish a chemical bond because it is a noble gas, hence its duplet is complete. Valency is therefore 0 (zero).

A noble gas or inert gas is helium. Due to having the most valence electrons that their outer shell or valence shell can support, noble or inert elements are the most stable. Because of its extremely stable structure, helium has no tendency to establish any chemical bonds.

Therefore, Helium is an element contain 2 protons, 1 neutron and 2 electrons.

Step 2 is the only step in glycolysis that is considered irreversible under cellular conditions, as it has the largest free energy change (-25 kJ/mol).

In this step, fructose-1,6-bisphosphate is cleaved into two molecules of glyceraldehyde-3-phosphate.

The glycolysis pathway is a crucial process for generating energy in cells. It consists of ten steps that convert glucose molecules into two molecules of pyruvate, generating a total of four molecules of ATP.

Step 2, in which fructose-1,6-bisphosphate is cleaved into two molecules of glyceraldehyde-3-phosphate, is the only step in the pathway which is considered to be irreversible under cellular conditions, as it has the largest free energy change (-25 kJ/mol). This step is catalyzed by the enzyme aldolase, and is followed by the irreversible conversion of dihydroxyacetone phosphate into glyceraldehyde-3-phosphate by the enzyme triose phosphate isomerase. The two molecules of glyceraldehyde-3-phosphate then enter the Embden-Meyerhof-Parnas (EMP) pathway, where they are further converted into two molecules of pyruvate, generating a total of four molecules of ATP in the process.

The somatic motor system relays instructions to muscles more quickly because it involves only one motor neuron, whereas the ANS uses a two-neuron chain. Moreover, axons of somatic motor neurons are typically heavily myelinated, whereas preganglionic autonomic axons are lightly myelinated and postganglionic axons are non myelinated.

The lateral component of the somatic motor system controls the premotor interneurons and motoneurons of the distal muscles. This component consists of two pathways—the lateral corticospinal and the rubrospinal pathways. In humans, the lateral corticospinal pathway subserves the control of the independent movements of the extremities. It controls the motoneurons via direct projections as well as indirectly via strong projections to the laterally located premotor interneurons.

The motoneurons innervating the muscles of the distal limbs receive the strongest direct projections from the motor cortex. This descending system enables humans to make most refined and extremely complex movements, such as independent finger movements and speech, the most complicated motor performance. In most mammals, both the lateral corticospinal and the rubrospinal pathways are important, but in humans the rubrospinal pathway seems to be irrelevant.

In the Galapagos Islands, finches were found to have differently shaped and sized beaks because shape and sized of  beaks, depends on the food present.

In Galápagos, finches evolved based on different food sources for example  long, pointed beaks served well for snatching insects while broad, blunt beaks work best for cracking seeds and nuts.

Darwin state that different species of finch have evolved on different islands, with distinctive beaks being an adaptation to distinct natural habitats or environmental needs .

The codon sequence on the mRNA strand determines the amino acid sequence of the polypeptide.

The coding section is the portion of the DNA that is also known as a gene. Genes are the functional units of DNA that provide the instructions for making proteins. They are composed of coding cells, also known as exons, that contain the information needed to build the polypeptide, and non-coding sections, also known as introns, that do not.

The codon sequence on the mRNA strand is translated by the ribosome during protein synthesis. Each codon, which is a sequence of three nucleotides, corresponds to a specific amino acid. The ribosome reads the codon sequence on the mRNA strand and adds the corresponding amino acids to the growing polypeptide chain. This process is called translation.

In DNA, genetic information is encoded in the sequence of nucleotides, which are the building blocks of DNA. Genes are specific segments of DNA that contain the instructions for making a specific protein. These instructions are encoded in the sequence of nucleotides within the coding sections of the DNA, also known as exons. The non-coding sections, also known as introns, do not contain instructions for making proteins, but they play important roles in the regulation of gene expression.

Explanation:

The above figure gives the cost figures for Jones Farm which producees wheat and sells it in the competitive market for wheat. The quantity of wheat produces in the figure is in the thousands of bushels.

At the market price of $10 for wheat Jones farm will reduce a thousand bushels of wheat in the short run, Jones farm will produce 4,000 bushels of wheat in the quick run and make earnings of $10,000.

To answer this question, you need to discover the income-maximizing output stage for Jones Farm, that is wherein the marginal revenue (MR) equals the marginal cost (MC). Since the market rate of wheat is $10 and Jones Farm is a fee-taker in an aggressive marketplace, the MR is likewise $10.

Looking at the discerning, you could see that the MC curve intersects the MR line at 4,000 bushels. This manner that Jones Farm will produce 4,000 bushels of wheat in the quick run to maximize its income.

To find the profit, you want to subtract the full value (TC) from the full revenue (TR). The TR is manufactured from the fee and the amount, which is $10 x 4,000 = $40,000.

The TC is given by the TC curve at 4000 bushels, which is $30,000. Therefore, the income is $40,000 - $30,000 = $10,000.
