Answer:
The correct answer will be- complex system.
Explanation:
A scientific investigation is performed to understand and explain the natural phenomenon using the scientific method.
An investigation is performed in one of the three ways: descriptive, comparative and experimental.
In the descriptive investigation, the investigation provides a descriptive account of any "complex system" by observing it when no prior knowledge is known. Therefore this method does not include the formation of a hypothesis.
Thus, complex system is the correct answer.
They are the endocrine glands
The answer is
B........................................
Woman's genotype: ii
Husband's genotype: I^A i
-> possible husband's father genotypes are two I^B and I^B i
-> if husband's father has two I^B alleles, the husband will have one I^B allele present, which is not the case. So, there is i allele present. (can also infer that I^A comes from husband's mother)
Child's possible genotypes:
ii, ii, I^A i, I^A i
probability is 1/2
