Answer:

c) type O

The woman has AB type blood group which means, gametes will be carrying the alleles of type A or B blood group and if the father has type O blood group the gametes will be carrying the gene which is recessive to both A and B.

It clearly refers to the child's blood group being either A or B.

Hence, c) type O is the correct option.

Which of the following statements concerning complex multicellular organisms is true?- Plants and animals use bulk transport sys
Minchanka [31]

<u>Answer:</u>

<em>The true statement concerning complex multi-cellular organism is Bulk transport systems move substances faster than simple diffusion.</em>

<u>Explanation:</u>

<em>Bulk transport</em> is the mechanism that is used by the cells to transport the large quantity of small and tiny molecules and particles. Bulk transport works on the <em>mechanism of pressure gradient and single diffusion</em> is based on the concentration gradient.

The<em> transportation on single diffusion</em> is due to random motion of molecules but in bulk transport the solute and water is moved <em>together and in a faster pace. </em>

If you made a Punnett square showing Gregor Mendel’s cross between true-breeding tall plants and true-breeding short plants, the
nekit [7.7K]

Answer:

C

Explanation:

Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.

In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).

We have the Gregor Mendel's cross as in the image attached here.

All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.

The answer is c (the offspring plants have a genotype that was different from that of both parents).
