Answer:
Photosynthesis is the process of making food by green plants in the presence of sunlight.
Explanation:
During Day, sunlight enters through stomata and carbon dioxide from air and water forms glucose and oxygen. This process is photosynthesis.
Plant cells have thick, sturdy cell walls, which provide rigidity and hold up the plant.
These various variations of a gene are referred to as alleles. For instance, two alleles may occur at one specific locus, one of which codes for the cytosine base and the other for the thymine base. One copy of the human genome is inherited from each parent. We are hence referred to as diploid organisms.
<h3>What is Allele Frequency ?</h3>
The relative frequency of an allele at a certain locus in a population, represented as a fraction or percentage, is known as gene frequency or allele frequency. The percentage of chromosomes in the population that carry that allele relative to the whole population or sample size is what is being discussed.
The frequency of an allele in a population is referred to as its allele frequency. It is calculated by dividing the number of gene copies by the number of times the allele occurs in the population. All the copies of every gene in a population make up the gene pool of that population.
<h3>What is Allele ?</h3>
Leading textbooks on genetics and evolution define an allele as a different variation of the same sequence of nucleotides at the same location on a long DNA molecule. "The chromosomal or genomic location of a gene or any other genetic element is called a locus and alternative DNA sequences at a locus are called alleles.

Answer:
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring
Explanation:
The term resistance in the exposed example refers to an inheritable change in the weed population sensitivity, which is reflected in the consecutive failure of the chemical effects on the herb population.
Herbicide might produce a genetic modification in the weed, leading individuals to survive under the effects of the chemical. The plants evolve with the capability of tolerating the chemical dose that is usually used to destroy a normal population of plagues.
Resistance to the toxic is associated with mutations in some of the genes.
A mutation is a change in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
- The selective pressure or modeling environmental factor is the triazine herbicide
- The weed´s response to herbicide is the survival of only those that carry mutations.
- Natural selection benefits these mutations.
- The mutated herbs survive, become more resistant, and pass the mutation to their offspring.
