belka [17]3 years ago
4 0

Answer:

The correct answer is - B. disruptive selection.

Explanation:

Adaptive radiation is a type of genetic drift that relatively fast evolution of many species from a single common ancestor which means there is a big drift in a very small time.

Disruptive selection is a type of natural selection that shows phenotypes (individuals with groups of traits) of both extremes but has very few individuals in the middle. An example of this type is the evolution of mammals after the extinction of dinnosaurs.

According to the principle of _______, a change in one species in a community results in a change in another.
Monica [59]

The correct answer is coevolution.

The term is used to illustrate the conditions where two or more species communally influence each other’s evolution. For example, an evolutionary modification in the morphology of a plant may influence the morphology of a herbivore that consumes it, this, in turn, may influence the evolution of the plant that might influence the evolution of the herbivore and so on.

Coevolution most possibly takes place when distinct species have a close ecological association with each other. These ecological associations include parasite/host and predator/prey, mutualistic species, and competitive species.

Match the gastric phase on the left (1-3) with the correct description on the right (4-6):
dem82 [27]

Answer:

1 and 5,

2 and 6,

3 and 4

Explanation:

Intestinal phase: stomach empties and decreases secretions

The intestinal phase is the phase where stomach empties its contents(chyme) and decreases secretion. In this stage the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes.

The Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.

Gastric phase: stomach secretes juice and mixes food into chyme

The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity  which secretes juice and mixes food into chyme. About two-thirds of gastric secretion occurs during this phase.

Cephalic phase: prepares stomach for arrival of food

The cephalic phase of digestion is the gastric secretion that occurs prior to when food enters the oral cavity. Cephalic phase result from the ignition of  visual, olfactory, and auditory inputs to the brain and also induce anticipatory responses i.e  prepare the gastrointestinal tract for the meal.
