Coyotes primarily feed on small mammals, such as rabbits, squirrels, birds, and mice. Many of these prey try to escape from coyotes by burrowing into the ground. Which of the following characteristics is most likely to be naturally selected to increase a coyote population's chances for survival over time?(1 point)

over time, the climate of a region becomes cooler. How will this most likely affect the species living in that region?(1 point)
Responses
Some species that already have or that develop cold-weather adaptations through natural selection will survive, while species without cold-weather adaptations may go extinct.

All of the current species living in the region will migrate to warmer areas, while species adapted to cold-weather climates will migrate into the region.

All of the current species living in the area will become extinct, and new species better adapted to the climate will form and populate the region.

Most of the current species living in the area will develop beneficial mutations, which will lead to adaptations that help them survive in the new climate

Many sponges can reproduce asexually. Ladybugs, on the other hand, reproduce sexually. When small bits of a sponge are broken off—often by currents or by predators—they can float to new regions and regenerate as new sponges. A ladybug must find a mate before it can reproduce.One disadvantage of the sponge's method of reproduction is that(1 point)

A potato plant can reproduce asexually so that one potato can often give rise to many other potatoes. Strawberry plants can reproduce sexually.A potato plant puts a large amount of its energy into growing a tuber, which is the part that humans eat. The tuber can grow large and provide energy for the plant during the winter, or it can be used to grow new potato plants. A strawberry plant, on the other hand, puts much of its energy into growing flowers to attract insects that aid in pollination. After fertilization, the strawberry plant must then also grow seeds as well as fruit to attract animals that disperse the seeds.Based on this information, the asexually reproducing potato plant most likely devotes _______ to reproduction than the sexually reproducing strawberry plant.(1 point)
