Answer:
A nutrient can be described as a substance which is used for the survival, growth and reproduction of an organism.
Three nutrients which plants require are:
NITROGEN (N): Nitrogen is important for growth and immunity. Without nitrogen, the plant will not be able to grow or produce immunity.
PHOSPHORUS (P): Strengthens root systems, capacity for seed creation, disease resistance, and pest prevention. Improves flowers and blooming. Also strengthens tissues and flavors in edibles and veggies. Without phosphorus, plants will not be able to produce sweet fruits.
CALCIUM
Strengthens and fortifies overall tissues everywhere. Also helps neutralize acidity, both within the plant and in its surrounding soil, for optimal health.
A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.
<h3>Dominant and recessive alleles</h3>
In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.
An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.
In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.
