Answer:
If the two organisms are heterozygous for the dominant trait.
Explanation:
For every trait, a diploid organism receives two forms of gene called ALLELE, from each parent. Allele is the variant form of a gene.
According to Mendel's law of dominance, for a particular trait, an allele is capable of masking the expression of another allele in a gene. The expressed allele is called the DOMINANT allele while the masked allele is called the RECESSIVE allele. Due to this, an organism can express a dominant trait even in a combined or heterozygous state i.e. different alleles.
When the two heterozygous organisms mate or are crossed, they undergo meiosis and their alleles are separated into GAMETES according to Mendel's law of segregation. For example; an organism with genotype (genetic make-up) Aa will produce gametes with A and a alleles.
Note that, a recessive trait can only be expressed in a homozygous state i.e. same allele. Hence, the two heterozygous organisms will produce gametes containing the recessive allele, which will likely combine to produce a recessive phenotype or trait.

Answer:
The correct answer is - Ψ = ΨS + ΨP.
Explanation:
The movement of the water in a solution where is two different concentrations present can be determined by measuring the water potential (Ψ).
Water potential (Ψ) can be determined by the equation that depends on these two factors osmotic potential represent by ΨS and pressure potential represent by ΨP.
Ψ = ΨS + ΨP.
Answer:
Depending on fern type, they can reproduce by spores, rhizomes, offsets or stems.
Answer:
Melanocytes are located in the stratum basale.
Explanation:
Melanin is the pigment responsible for skin color. It is produced by melanocytes located in the base of the epidermis.
The epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
Stratum basale is the innermost germinative, single, basal layer of the epidermis composed of basal cuboidal-shaped cells. These cells are the <em>precursor of keratinocytes</em>, this is why this layer is also called germinativum. In this basal layer, there are also <em>Merkel cells</em> as well as melanocytes.
