Answer:
A. The dominant factor, or allele, is for round seeds.
Explanation:
Gregor Mendel discovered the principles that governs inheritance. During his numerous experiments, he conducted a cross in pea plants involving a single character. This cross is called MONOHYBRID CROSS. In one of these monohybrid crosses, he observed the gene for seed shape in pea plants. He discovered that two alleles are responsible for the expression of this gene: round allele (R) and wrinkled allele (r).
He crossed plants that produced only round seeds i.e. homozygous RR and plants that produced only wrinkled seeds, rr. He observed that the F1 offsprings were all round-seeded. This made him to propose his LAW OF DOMINANCE, which states that an allele is capable of masking the expression of another in a gene. He concluded that the round allele is covering the wrinkled allele in a heterozygous state, since it is expressed over it. He then called the round allele, DOMINANT allele and the wrinkled allele, RECESSIVE allele.
Nummular is a term to describe a lesion size. Nummular size is about a coin size, or 3cm x 5cm. Other sizes could be miliar which was about a dot, lenticular which was around a lentil, and plaque which sizes around a palm of the hand. This size description is not really descriptive since it has various ranges. Actual size in centimeter unit might be better to describe a lesion.
Answer:
it is an obligate (or strict) aerobe
Explanation:
By whether an organism requires oxygen or not for respiration. We can classify it as either aerobic or anaerobic.
Aerobic organisms require oxygen and anaerobic do not.
For aerobes, it can be facultative or obligate. Facaltative aerobes require oxygen but they can however switch to fermentation when oxygen is not available.
Obligate aerobes are aerobes require oxygen for cellular metabolism.
In the test the dextrose tube remained yellow because fermentation had not taken place.
Therefore we can conclude the sample contained an obligate aerobe which was catalase positive since it produces bubbles when Hydrogen peroxide was added.
