The answer to this question would be: <span>b.electromagnetic or weak nuclear
</span>
The electromagnetic force can be repulsive or attractive because it was influenced by the magnetic charge. The same charge (positive with positive) will be repulsive but different charge will be attractive(negative and negative). The gravitational force will always be attractive, not repulsive. 
Weak nuclear can do both like electromagnetic force.

egoroff_w [7]

Answer:

a. Trisomic

Explanation:

A trisomy is a genomic phenomenon whereby a particular chromosome is present in three copies. In this case, the trisomy involves the chromosome P, being this species a tetraploid with 5 pairs of homologous chromosomes (2n = 10). In humans, the trisomy for chromosome 21 is one of the most common types of aneuploidies that lead to the Down syndrome by producing alterations in gene expression patterns that are associated with changes in the phenotype

denis-greek [22]

Answer:

The best method of investigation that a scientist can use in an investigation of twins separated at birth - as in the case of Trinna and Suzanne - is a case study.

Explanation:

The case study is a qualitative research strategy that can be used in both biology, psychology and sociology, even combining these disciplines. Take an observed phenomenon, sometimes unique, looking for an explanation based on the examination and the elaboration of hypotheses.

Trinna, despite being an identical twin, developed a shorter stature and habits different from Suzanne, probably due to her growth in different environments.

The objective of the case study would be to demonstrate how the growth of twins in different settings may have caused physical and cultural differences in these identical twins.
