The main function of a cell's genetic material is it encodes proteins.
Thus, the correct option is C.
The nucleus contаins genetic (hereditаry) mаteriаl. Genetic mаteriаl, written in deoxyribonucleic аcid (DNА), provides instructions for the cell. Аll cells contаin the sаme DNА (the sаme set of instructions), but cell types аre different becаuse of different gene expressions. For exаmple, skin cells аnd blood cells look аnd function differently. In other words, they follow different pаrts (genes) of the sаme instructions (genetic mаteriаl).
Hence, genes encode proteins аnd proteins dictаte cell function. Therefore, the thousаnds of genes expressed in а pаrticulаr cell determine whаt thаt cell cаn do.

Fat
Explanation:
Fat provides the most energy of all the macronutrients, at a whopping 9 calories per gram.
can you describe what cause the discrepancy betweent the theorhetical tensile strength and the actual strength
Defects cause the discrepancy between the theoretical tensile strength and the actual strength.
Due to the fabricated structure's numerous flaws, including faults and surface roughness, the actual tensile strength is substantially lower than the theoretical strength and varies greatly. The strength of SCS was reported to be between 0.5 and 10 GPa, indicating the presence of fracture-initiating defects with a length greater than 0.5 m. (Tsuchiya et al. 2005). The surface geometry is regarded as the key determinant of fracture strength in silicon microstructures. For instance, the roughness of the etched surfaces dominated the strength of the micromachined structure made from SOI wafer utilising DRIE methods (Izumi et al. 2005).
Because nothing in reality is flawless, the theoretical strength is computed for perfect materials (without any flaws or blemishes). For all materials, this is true. Hence results in discrepancy .
Only a small number of faults are required for brittle materials to break since they have little elongation range and do so promptly when they approach the breaking point.

Still, we do not know if the trait is dominant or recessive, yet.For the textures trait, both parents are spinny, but 3/4 of the progeny is spinny while the other 1/4 is smooth. This tells us that the dominant trait is spinny: not only both parental express it, but also because 3/4 of the progeny express it too.

The offspring of the cross between two pea plants of RR YY will have a phenotypic ratio of 100% round yellow seeds and a genotypic ratio of 100% Rr Yy.
The phenotypic and genotypic ratios in offspring of a cross between two pea plants of RRYY genotype can be determined by considering the inheritance of traits controlled by the alleles present in the parent plants. In pea plants, the dominant R allele codes for round seeds and the recessive r allele codes for wrinkled seeds, while the dominant Y allele codes for yellow seeds and the recessive y allele codes for green seeds.
In a cross between two RRYY pea plants, the offspring will all be heterozygous for both traits (RrYy). The phenotypic ratio of the offspring can be calculated as the proportion of plants expressing each phenotype. In this case, all the offspring will have round and yellow seeds (the dominant traits), so the phenotypic ratio will be 100% round yellow (RrYy).
The genotypic ratio, on the other hand, represents the proportion of plants with each combination of alleles. In this case, the genotypic ratio of the offspring will be 1:1 for RrYy and rryy (50% each).

recessive traits carried on the x chromosome affect the phenotypes of sons more often than those of daughters because:
Recessive traits carried on the X chromosome affect the phenotypes of sons more often than those of daughters because of a phenomenon known as X-linked inheritance.
X-linked inheritance is a type of genetic inheritance in which a gene is located on the X chromosome and is expressed in males and females differently.
In humans, females have two X chromosomes, while males have one X and one Y chromosome. This means that a gene located on the X chromosome will be expressed in a male if he inherits one copy of the gene from his mother, but not if he inherits it from his father, who does not possess an X chromosome. On the other hand, a female will express a gene located on the X chromosome if she inherits it from either parent.
Since a male has only one X chromosome, if he inherits a recessive trait from one parent, he will display the trait regardless of whether he inherited it from the other parent. This means that traits located on the X chromosome are more likely to be expressed in males than in females.

in transcription, the energy to attach each successive ribonucleotide to the growing rna chain comes from:
The hydrolysis of the high-energy phosphate bonds in the nucleoside triphosphates (NTPs) utilised as substrates provides the energy needed to link each succeeding ribonucleotide to the expanding RNA chain.
In particular, the reaction's energy comes from the NTPs' terminal phosphates being broken apart, which releases two molecules of inorganic phosphate (Pi) and creates the matching nucleoside monophosphate (NMP).
The RNA polymerase enzyme is the catalyst for this process, which is referred to as a "nucleophilic assault." The freshly added ribonucleotide and the lengthening RNA chain create a phosphodiester bond using the energy produced during this process.
This incredibly efficient process can happen whenever a nucleotide is introduced to the RNA chain every two seconds.
