7. Why is it impossible for a parent with type AB blood to have a baby with type O blood?
maxonik [38]

Answer: This is because a parent with type AB blood has both A and B antigens therefore, the child must inherit either A or B antigen from the parent.

Explanation: In ABO blood type, blood types are classified on the basis of the antigens present in the red blood cells. There are two types of antigens: A and B antigens.

A blood type is so named because it has A antigens, B blood type has B antigens, AB blood type has both A and B antigens while O blood type has no antigens.

Each of these blood types is controlled by two alleles, and children inherit one allele from each parent. If a parent has AB blood type, none of his offsprings will have O blood type because each offspring must inherit either antigen A or B from this parent.

Brainliest:Both the euglena and paramecium seen here have___?
forsale [732]

Answer:

projections that help them move

Explanation:

Euglena and paramecium both belong to the Kingdom Protista. They are very minute single cellular organisms but have many differences among them. Paramecium is more similar to animals in many of its characteristics while Euglena is more similar to plants in its characteristics. This is because Euglena just like plants can make their own foods through chloroplast while paramecium just like animals cannot make own food.

However what is common in both of these are projections that help them move . Paramecium have projections called cilia around the whole body while Euglena has a whip like flagella which helps it to move.

Hope it help!
