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
A.
its offspring have little genetic diversity.
B.
it requires more energy.
C.
its offspring have greater genetic diversity.
D.
it must devote a greater portion of its life cycle to reproduction.

A. its offspring have little genetic diversity.

Explanation:

Unlike the ladybug who needs a mate, the sponge reproduces by itself. This means the new sponge offspring usually do not differ much from the parent, as most of its genes will come from there and will not come from two parents 'mixed' together. This means not much varieties of sponge offspring would come from the same parent.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
