Answer: Experiment.
Explanation:
Suppose that we have two related variables, A (independent) and B (dependent)
We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.
This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.
The right option is; extreme traits
Disruptive selection events select for extreme traits.
Disruptive selection is a type of natural selection in which organisms with extreme traits are favored (such as in reproduction) over organisms with intermediate traits. This type of selection results in increased traits differences with increase in frequency of the alleles for the extreme traits. Disruptive selection can lead to the digression in a species line.
Answer:
D
Explanation:
Homologues separate to opposite ends of the cell. Sister chromatids stay together. Telophase I: Newly forming cells are haploid, n = 2.
According to Thelen {1986}, THE STEPPING REFLEX may contribute to the birthing process.
Stepping reflex is one of the reflexes demonstrate by new born babies. When resistance is exerted on the feet of a new born baby, the baby will respond by placing one foot in front of the other, this is called stepping reflex and Thelen suggested that this reflex may help in the birthing process.
