Quincy has type B blood.
Irina-Kira [14]

Answer:

IBi and IBIB

Explanation:

Blood group in humans is determined by a single gene with three alleles (iA, iB and i). Alleles iA and iB are both dominant over i. This means that i allele will only be expressed in a homozygous state.

In the ABO blood group system, individuals will possess the following blood types when they possess the following genotypes:

Type A- iAiA or iAi

Type B- iBiB or iBi

Type O- ii

Alleles iA and iB are codominant, this means that they both phenotypically express themselves when combined as neither is dominant or recessive to the other. Hence, in an heterozygous state;

iAiB, the blood type of the individual will be Type AB.

Following this, Quincy with a type B blood will possess an allelic combination of iBiB (homozygous) or iBi (heterozygous) in her genotype.

Pepsi [2]

Ans.

<em>Viscum album </em>is a plant species, commonly known as mistletoe. It is a hemi-parasitic plant that grows on other trees.

Birds cause seed dispersal as they pick seeds from parent plant and drop them in other places. Seeds of mistletoe are sticky or viscous due to mucus and they provide nutritious food to the birds.

Hence, it can be concluded that the mistletoe seeds show adaptations primarily for seed dispersion, not for infecting the host plant.

Thus, the correct answer to be filled in the blank is 'is nutritious to the dispersing birds.'
