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
it produces genetically identical offspring, which means that there is no variation in the population and it is more susceptible to diseases and environmental changes. In contrast, the ladybug's method of reproduction produces offspring with different genetic traits, which increases the likelihood of adaptation and survival in changing conditions.
could you pick one of these answer choices?
a. it requires more energy.
b. its offspring have little genetic diversity.
c. its offspring have greater genetic diversity.
d. it must devote a greater portion of its life cycle to reproduction.
b. its offspring have little genetic diversity.
Which of the following is a method of reproduction that generally occurs very rapidly?

A new predator is introduced into the ecosystem shown in the food web below. This predator feeds on bees and mice. How will this most likely affect the species in this ecosystem?
There will be a decrease in bees and mice which will cause an increase the black bear population and a decrease in the fox population.
There will be an increase in bees and mice which will cause an increase in the populations of both black bears and foxes.

A widow's peak is a V-shaped area of the hairline in the center of the forehead. The allele for having a widow's peak is dominant to the allele for not having a widow's peak.If two parents do not have widow's peaks, what is the probability that their child will have a widow's peak?

Both of Tim's parents have brown eyes, but Tim has blue eyes. How is this possible?
The characteristic (blue eyes) is carried in a recessive gene.
This characteristic (blue eyes) must be carried in the dominant gene.
Eye color is not a genetic trait.
