Answer:
Spotted Eagle Rays have two sets of five gills on each side of their body on the ventral side. In order to breathe, A. narinari must be in continuous swimming motion so that oxygen can be absorbed from the water passing through the gills
Explanation:
Most sponge body plans are slight variations on a simple tube-within-a-tube design. which of the following is a key limitation of sponge body plans? sponges lack the specialized cell types needed to produce more complex body plans. the reliance on osmosis/diffusion requires a design that maximizes the surface area to volume ratio of the sponge. choanocytes must be protected from the hostile exterior environment. spongin cannot support heavy bodies.
The independent variable is the type of food available.<span>The dependent variable is the frequency of each type of beak (or number of birds with each beak type)</span>
Answer:
Multifinality
Explanation:
Multifinality refers to a process where a similar start state (levels of a behavior, type of attachment), results in multiple pathways that lead to different outcomes
Answer:
C. 1/4
Explanation:
Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=
9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.
Therefore, the proportion of the progeny with long horns = 4/16= 1/4
