geniusboy [140]

Answer:

The correct answer is : oxygen

Explanation:

  • Oxygen is carried in the blood by two means:
  1. About 2% of the oxygen is carried in the dissolved form in blood plasma and in the water present in the red blood cells (RBCs).
  2. Rest 98% of the oxygen is carried in bound form with the haemoglobin as oxy-haemoglobin inside the RBCs.
  • RBCs lack nucleus. This place is occupied by hemoglobin molecules that  binds to oxygen and form oxy-hemoglobin.
  • This increases the capacity of each RBC so that it can carry more oxygen to all the parts in the body.

The R locus determines flower color in a new plant species. Plants that are genotype RR have red flowers, and plants that are rr
tatiyna

Answer:

The correct answer will be- Non-Mendelian inheritance (incomplete dominance)

Explanation:

Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.

In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.

Cross

RR (red) x rr (white) = Rr (pink)

Thus, incomplete dominance is the correct answer.
