Biology
1 answer:
Scorpion4ik [409]3 years ago
8 0
The correct minerals and vitamins for a pregnant are iron and folate. Iron generally should be supplemented, and folic acid supplements often are needed because folate is so important. Iron is used to make extra blood (haemoglobin) for the mother and the fetus. Folic acid helps prevent neural tube defects.

AlladinOne [14]

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.

Describe the adaptations of plants to different habitats.​
qaws [65]

Answer:

Plants adapt or adjust to their surroundings. This helps them to live and grow. A particular place or a specific habitat calls for specific conditions and adapting to such conditions helps the plants to survive. ... If the habitat changes drastically the plant species must adapt, otherwise they would not survive.

Explanation:

Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another.
