Scorpion4ik [409]

Answer:

c, disruptive selection

Explanation:

Disruptive selection is a term used to describe population genetic changes that simultaneously favor individuals at both ends of the distribution. When disruptive selection operates, individuals at the extremes contribute more offspring than those with intermediate characteristics, producing two peaks in the distribution on a graph.

In the excerpt shown in the question, long-gill-striped and gill-striped fish were favored by the selection process than intermediate-length striped fish. For this reason we can conclude that a disruptive selection was taking place.

Assign each characteristic to the appropriate type of muscle fiber.
olga2289 [7]
I found the full exercise on the internet. Attached is an image of the characteristics and the types of muscle fibres.

Fast twitch:
- few mitochondria (most of the energy comes from acid lactic fermentation)
- low myoglobin content (O2 is not used as the main source of energy)
- shorter twitches
- anaerobic (uses mainly glucose and no O2)
- easily fatigued (as soon as glucose storage finishes fatigue comes in)
- high glycogen content (glucose as the main source of energy and therefore more glucose storage in the form of glycogen)

Slow twitch:
- high myoglobin content (energy comes from O2 and therefore is needed much myoglobin)
- aerobic (uses O2)
- low glycogen content (as O2 is the main source of energy, glucose is not needed as much)
-longer twitches
