Moose make mating calls to locate potential mates
Bingel [31]
<span>Moose are generally docile towards humans, but may become more aggressive during the mating season of September through October.The name "moose" comes from the Native American word "Moswa," which translates to "twig eater."On average, moose live 10 to 15 years in the wild. Moose are considered fully mature at 4 to 5 years of age.Moose are remarkably agile for their size, capable of running at speeds of up to 35 miles per hour.Moose are capable of swimming up to 10 miles without stopping.Moose are unlike many other deer species in that they are mostly solitary animals. However, strong bonds exist between mothers and calves.The moose population in North America is estimated to be fewer than 1.5 million, with 1 million in Canada alone. Up to 200,000 are estimated to live in Alaska.Moose are herbivores, and eat a large amount of terrestrial vegetation, but they also must need to consume a good amount of aquatic plants which provide moose with sodium.Moose must consume 9770 calories per day to maintain their body weight.A moose will eat up to 70.5 pounds of food a day.If a bull moose is castrated, he will shed his current set of antlers and grow new, deformed and misshapen antlers which will never be shed again. These antlers are often called "devil's antlers" and are the source of several Native American myths. In rare cases, cow moose may grow antlers due to a hormone imbalance.Because of their heavy bodies suspended by spindly legs, moose are especially dangerous when hit by passenger cars. If you are driving in an area where moose are plentiful, use caution and pay attention at all times.<span>Moose antlers may weigh up to 70 pounds, and measure 6 feet across.</span></span>

Avian snail kites are visual predators, preying on light-colored apple snails. Avian limpkins are tactile predators, preferentia
quester [9]

Answer:

<em>The correct options are D. dark-colored, small-sized snails and F. dark-colored, large-sized snails</em>

Explanation:

Evolutionary studies show that those organisms are able to survive and reproduce which are better adapted to live in an environment. Gradually, the organisms that are better adapted to live in an environment increase in number and those that are not better adapted will decrease in population.

As Avian snail kites feed on light- colored apple snails and Avian limpkins feed on medium- sized apple snails, this means that these species are not better as they can be easily captured by their predators.

The dark colored, small- sized snails and dark- colored, large- sized snails will be better adapted to live in the environment as they will not attract the predators. Hence, they will survive and reproduce.
