Two members of a homologous chromosome pair have genes in common, along with their identical shape and size.

Homologous chromosomes are two bits of DNA within a diploid organism that carry identical genes from both parents.

To put it another way, both of your parents give a full genome. Each parent contributes the same 23 chromosomes, which code for the same genes. As a result, our cells contain 46 chromosomes in two copies. Each homologous chromosome, however, can offer a distinct version of each gene. Two copies of each gene increase variety, reduce the negative impacts of negative mutations and generally stabilize a population.

The pairing of homologous chromosomes during meiosis promotes genetic diversity. Because of the genetic recombination that happens between homologous pairings during meiosis, the resulting haploid gametes have genetically distinct chromosomes. This expands the gene pool, improving the chances of receiving genes required for biological fitness and survival.

There is a loss of energy as the level moves up in a pyramid.

A food pyramid is a graphical representation that depicts the recommended daily intake of different food groups. It typically consists of five or six food groups arranged from the bottom to the top in order of the amount that should be consumed daily. The bottom tier represents the largest food group, such as carbohydrates, and the top tier represents the smallest food group, such as fats and oils.

The food pyramid provides a visual representation of the proportion of different food groups that should be consumed to maintain a balanced diet and promote good health. The transfer of energy in a food pyramid occurs as energy is passed from one level to another, with a loss of energy at each transfer due to metabolic processes and waste production.

The concentration of hydrogen ion in eukaryotic cell would be 1.0 × 10^-7 M.

The pH of 7.4 in a typical eukaryotic cell corresponds to a hydrogen ion (H⁺) concentration of approximately 1.0 × 10⁻⁷ moles per liter (M). The pH scale is a logarithmic scale that measures the concentration of hydrogen ions in a solution. A pH of 7.4 is considered neutral, with values less than 7.4 being considered acidic and values greater than 7.4 being considered basic.

To calculate the hydrogen ion concentration, you can use the following formula:

[H⁺] = 10^-pH

Where pH is the measured pH value. So, for a pH of 7.4, the hydrogen ion concentration would be:

[H⁺] = 10^-7.4 = 1.0 × 10^-7 M

Multiple codons can pair with numerous tRNAs.This indicates that many amino acids are specified by multiple codons.

Because the right field in the tRNA anticodon can recognise two or more distinct codons on an mRNA, since there are 61 different base pairs that code again for 20 amino acids, there are just 45 different tRNAs. We refer to this capacity for different codon recognition as "wobble." Due to the genetic code's redundancy, 61 triplet codons require 32 tRNA. This indicates that many amino acids are specified by multiple codons. The fact that a tRNA frequently can obtain more than one of these codons means that the cell does not have to produce numerous tRNAs to bring the same amino acid. Less than 61 transfer RNAs are used in the standard genetic code to translate 61 codons into 20 amino acids.

Silent mutations arise when a single DNA nucleotide alteration inside a protein-coding region of a gene has no effect on the amino acid sequence that makes up the gene's protein.

Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation. The phrase silent mutation is often used interchangeably with the phrase synonymous mutation; however, synonymous mutations are not always silent, nor vice versa.

Synonymous mutations can affect transcription, splicing, mRNA transport, and translation, any of which could alter phenotype, rendering the synonymous mutation non-silent. The substrate specificity of the tRNA to the rare codon can affect the timing of translation, and in turn the co-translational folding of the protein.

If the pollen is too genetically similar, it can still be prevented from germinating by the gametophytic self-incompatibility mechanism. Here option D is the correct answer.

Self-incompatibility (SI) is a mechanism that prevents self-fertilization in plants, and it is a way of maintaining genetic diversity in the population. In gametophytic self-incompatibility, the SI system is located in the female gametophyte and prevents fertilization by sperm cells from the same plant or from genetically similar plants.

If a pollen spore is unable to carry S (self-incompatibility) proteins in its pollen coat, it can still be prevented from germinating if it is too genetically similar to the female gametophyte through the gametophytic self-incompatibility mechanism. This mechanism works by recognizing and rejecting genetically similar pollen.
