Answer:
In a diploid organism there are two copies of most genes.
The versions of the genes are called alleles.
Explanation:
Hello!
The genetic servants of a population are all variants of each of the genes present. These variables are possible thanks to the mutations that occur in the formation of the zygote (before or after fertilization).
When part of the DNA of an organism undergoes a point mutation (on one or a few nitrogenous bases) the body activates a series of responses to reverse it, however sometimes the mutation is maintained and can give rise to a change in a protein.
Sometimes and under certain circumstances (the change should not cause death or significant disadvantages in the body that is born) the mutation is maintained in the population giving rise to different alleles of the same gene.
In an organism there are two copies of each gene (genotype) but only one of them (phenotype) is expressed.
The allele of the gene that is expressed may depend on various factors but the dominant allele is usually expressed.

This is a case of acute or chronic (or acute on chronic) kidney disease. Mateo should take diuretics or drugs that induce tubular secretion and/or water excretion and therefore urination. If kidney disease worsens, the patient will undergo filtration of waste products from his blood or this is called hemodialysis. There is another way of filtering waste products using the fluid in the peritoneum called peritoneal dialysis. Other complications of chronic kidney disease is anemia as erythropoeitin (functions to signal the production of red blood cells) is produced in the kidneys.
Answer:
The correct option is B.
Explanation:
Lichens is regarded as a mutual relationship between a mycobiont and photobiont, the relationship is targeted at enhancing their survival in extreme environments. The mycobiont is a fungal while the photobiont is usually a green alga or a mycobacterium. Each of the organism has their specific tasks; the mycobiont provides suitable habitat for the photobiont while the photobiont provide energy for the whole system.
