The correct answers are:

Alfred Wegener has spent lot of times looking at maps, as it was his job. One day he noticed something peculiar, the western coast of Africa and the eastern coast of South America were an almost perfect match. They looked like peaces of puzzle that belong together. In his mind this was suggesting that these two continents had been merged in the past, and than broke apart. He later got proof about his theory by observing the sea mounts in the Atlantic Ocean.
I think the more features two organisms share or the shared anatomical features, the closely related they are. For example; the class insecta (e.g bee, butterfly) and the class arachnida (e.g spider and tick) belong to phylum arthropoda because they have similar anatomical features such as appendages, segmented body among other features.
People in a secondary group interact on a less personal level than in a g. Since secondary groups are established to perform functions, people’s roles are more interchangeable. A secondary group is one you have chosen to be a part of. They are based e where many people can meet close friends or people they would just call acquaintances. Secondary groups are groups in which one exchanges explicit commodities, such as labour for wages, services for payments, etc. Examples of these would be employment, vendor-to-client relationships, etc.The distinction between Primary and Secondary groups serves to identify between two orders of social organization through analysis of the group relationships and their nature.
The answer would be: <span>A.50%
A child will get genetic material from both parents, half from the father and half from the mother. This is why the gamete cells (sperm/ovum) are made from meiosis and only have 50% of the original genetic material.
</span><span>In this case, the parent carries a deletion on one of the two homologous chromosomes. Since the gamete only has one of the chromosomes, half of the gamete of this parent would have the defective chromosome and the other half have a normal chromosome. So, the chance for the child to inherit the defective gene is 50%.</span>
Explanation:
Although blood group studies cannot be used to prove paternity, they can provide unequivocal evidence that a male is not the father of a particular child. Since the red cell antigens are inherited as dominant traits, a child cannot have a blood group antigen that is not present in one or both parents.
