An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit ______ as a larva and ______ as an adult. bilateral symmetry . . . bilateral symmetry bilateral symmetry . . . be asymmetrical radial symmetry . . . radial symmetry radial symmetry . . . bilateral symmetry bilateral symmetry . . . radial symmetry

Answer:

Bilateral symmetry as a larva

Radial symmetry as an adult

Explanation:

Bilateral symmetry refers to the division of the animal through a longitudinal plane, int two mirror-image, right and left halves, as seen in organisms such as insects, reptiles or in man. Animals with bilateral symmetry have anterior and posterior halves (head and tail), dorsal and ventral (front and back), and right and left sides. Most animals are bilaterally symmetrical. Animals with bilateral symmetry are best suited for active lifestyles involving streamlined and directional motion.

Radial symmetry refers to the arrangement of body parts around a central axis, just like rays on a sun, ie.they have bodies that seem to radiate outwards from a central point. Animals that are radially symmetrical have top and bottom surfaces only but no left and right sides, or front and back sides. Animals that have radial symmetry are best suited for sedentary lifestyles and are usually attached to some surface (sessile)

An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit bilateral symmetry as a larva and radial symmetry as an adult.

5) Taxonomy is defined as the science of

Suppose you travel to a tropical place like the Bahamas and watch the coastal poikilotherms, such as fish, crabs, and starfish, swim and crawl about in the warm waters. Suppose then that you travel to northern Maine and watch the related species of poikilotherms in the cold waters there. It would not be unreasonable to expect to see the animals in Maine moving about in slow motion compared to those in the Bahamas. In fact, however, rates of locomotion are likely to look to your eye to be more similar than different in the two places. Design experiments to assess whether the Maine animals are especially able to be active in cold waters. If you find that they are, how might their high ability for activity in cold waters be explained

A model of evolution is shown here. The original population has alleles for type A blood (red) and alleles for type B blood
(blue). Which statements are supported by the information in the model? Please select ALL that apply,
A)
The genetic diversity for islands A and C is reduced after genetic drift.
B)
The founder effect is a mechanism of evolution that includes a random
factor that influences allele changes.
Islands A and C had founding members with very different allele
combinations than the original mainland population.
D)
The members of the founding population for island B are the most
representative of the original population on the mainland.
Islands A and C have undergone natural selection, which reduced the
genetic variation of the alleles on each of those two islands,
E)

How does an individual with a competitive advantage lead to the evolution of an entire species?(1 point)

A) Some individuals are better at competing for resources, and that allows them to survive droughts or other major ecological events, leading to the extinction of certain species and the survival of others.

B) Traits that are advantageous help certain individuals reproduce at higher rates, so those traits are more common within the population.

C) Those who have traits that help them survive are able to reproduce, and their offspring have those traits, leading to a change in the species over time.

D) Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.
