Answer:
B. Genotypes
Explanation:
The genotype of an organism refers to the genetic makeup of that organism. It is the combination of all the genes contained on the chromosomes of that organism. Gregor Mendel, who is considered to be the Father of Genetics, discovered that certain factors are responsible for the physical characteristics of organisms and that they can be transferred from one generation to another. These factors are called GENES. Genes are located on X-shaped structures called chromosomes.
Hence, the isolation of chromosomes taken from tortoise blood samples refers to recording their GENOTYPE (genetic constituent).
Answer:
a. activation of the sympathetic autonomic nervous system by the new experience.
Explanation:
The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.
An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested the experimentation. The results of experimentation lead to changes in scientific knowledge.
