Answer: asexual reproduction
Explanation:
From the question, we are informed that Brady took a cutting from a sweet potato vine in his family garden and placed the vine in a small vase filled with water. We are further told that after about a week, tiny roots had begun to grow. This is simply an example of asexual reproduction.
Asexual reproduction is simply refers to a form of reproduction which doesn't have to do with changing the chromosomes or gametes fution. In this case, the fact that tiny roots began to grow despite the fact that there was no fusion of gamete shows that it's an asexual reproduction.
Answer:
d.The transferred traits were heritable.
Explanation:
Griffith's experiments with S. pneumoniae were significant because they showed that traits could be transferred from one organism to another and these transferred traits are known to be as heritable traits. In another experiment carried out by Hershey and Chase experiment it was confirmed by the results that DNA is actually the hereditary material not the protein.
<span>Hippocrates believed that there are four humors in human body which need balance for a healthy being. These were:
Blood, phlegm, yellow bile, and black bile.</span>
Galen expanded the idea of the humors and introduced four temperaments which were these:
choleric (hot / dry), melancholic (cold / dry), sanguine (warm / moist), and phlegmatic (cold / moist).
Another expansion Galen did was that he gave each humor/temperament physical and psychological qualities and said that even the food items have an association with the certain humor, those foods can effect certain humor in certain ways.
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.

Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).
On the other hand, a Mendelian trait is controlled by a single locus.
