Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and

is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities.

(Answer:) this is most likely to be scientific, (Explanation:) because, if you look at the question it says 'are the effects of medditadion scientific?... ect', and if you look back on your description of meditation, in the third sentence, they certainly state information based on scientific study!

Eric has blood type O. What could be the genotype of his grandmother Tricia? Select all that apply.
sleet_krkn [62]

Answer:

C. IBIB

D. IBiO

Explanation:

The blood group system comprises of three different kind of alleles, iA, iB, IO. As we know that a person gets two alleles for both traits, one from father and one from mother, and based on that a person gets its blood group. IA and IB are dominant to IO.

So, if a person has genotype IAIO he will have blood group A and if he has genotype IOIB he will have blood group B because A or B are dominant to O.

However, if a person has blood group O it means that he has genotype IOIO.

So, in this diagram we see that Eric has blood type O, which means that his genotype will be IOIO.

The Eric's mother Melissa has blood group B, which means that she can either had genotype IOIB and IBIB respectively.

Similarly, Eric's grandmother Tricia has genotype  B which means that she can have genotype both  IOIB and IBIB respectively.

Therefore, both C and D are correct options.
