Answer:
The correct answer is -
Parental genotypes: AO & BO
Children genotypes: AB, AO, BO, and OO
Explanation:
In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.
Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.
The cross depicting the genotypes of children is
IA IO
IB IAIB IBIO
IO IAIO IOIO
In this cross, we get the same result as given in the question -
One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.
Answer:
a. Gram negative
Explanation:
Lipopolysacchirides are found in the outer membrane of gram negative bacterial cell wall exposed to surface and are endotoxins that protects them from harmful chemicals. They are composed of lipids and polysaccharides. Gram negative bacteria are pathogenic due to their cell wall.

Explanation:
Sorry if I answered late I was looking for the answer of this question too.
The pattern of embryonic development in which only the cells lacking yolk subsequently undergo cleavage is called meroblastic development, which is typical of birds.
Therefore, the correct answer is Option D.
<h3>What is embryonic cleavage?</h3>
- Embryonic cleavage is the division of cells which occurs just after fertilization and are involved in the early development of the embryo.
- The different cells formed after cleavage are called the blastomeres and these are present in a compact mass called the morula.
- The end product of cleavage is blastula which is a hollow sphere with a cavity called blastocoel.
- Cleavage can be of different types depending upon the concentration of yolk in the egg as yolk does not undergo cell division.
- In holoblastic cleavage, the entire egg divides as yolk is present in very less concentration.
- In meroblastic cleavage, only the cells lacking yolk divide.
