Please solve A population.of hermit crabs finds discarded shells from other animals and wears the shells as protection.As the crabs grow, they must find larger shells. However, the crabs' bodies are angled either left or rightand they can only use shells with openings to accommodate their body opening. A left-angled crab canonly use a shell with a right-facing opening. A right-angled crab can only use a shell with a left-facingopening. There are a limited number of shells available in the environment and crab incapable of finding anew shell face a much greater risk of predation. During the first observation period, the majority of crabsin the population are right-angled. Select the best explanation for likely changes over time.Since most crabs are right-angled, this suggests this characteristic is beneficial in the environment. Thus,right-angled will likely continue to be the most common phenotype.O The proportion of right- and left-angled crabs will vary mostly as a function of random changes due togenetic drift.The relative fitness of the right-angled crabs will decrease and left-angled crabs will begin to be morecommon in the population.Since we can't predict gene flow, we cannot make a prediction.

Given that majority of the population is with right angled.

Figure 27.9 Which of the following statements about diploblasts and triploblasts is false? Animals that display radial symmetry are diploblasts. Animals that display bilateral symmetry are triploblasts. The endoderm gives rise to the lining of the digestive tract and the respiratory tract. The mesoderm gives rise to the central nervous system.

pome A fish species you are studying lives in both rivers and lakes. In rivers, they are skinny and long, whereas in lakes they are shorter and wider. You collect fish eggs from each location and rear the fish in an aquarium in your lab. Once they are adults, you measure their length & width and find that fish from rivers and streams have the same average length & width. Based on this study, what is the most reasonable conclusion you can make about body shape in this species? LAKE RIVER LAB Lake Lake River O Directional selection has led to the evolution of body shape in one of the populations. O Differences in body shape seen in the field are likely due to genetic drift. Differences in body shape seen in the field are due to phenotypic plasticity. O We can't make any of these conclusions based on this information alone.
4) Animals that undergo ecdysis, or molting, include nematodes and arthropods. Why do these animals molt? Group of answer choices shedding the exoskeleton allows the animal to move faster to escape predators the exoskeleton prevents them from obtaining oxygen their outer covering is made of a non-living substance shedding the exoskeleton makes the animal smaller, which makes it easier for the animal to hide from predators in crevices
Animals that live in the upper tide zones have no chance of survival. O soft bodies. Bright colors. O hard shells.
Insects display an incredible diversity of body forms and ecological roles. Some insects undergo complete metamorphosis, a lifecycle involving distinct larval, pupal, and adult stages. How might this lifecycle contribute to the success and diversity of these insects? It allows the larval and adult stages to exploit different resources or habitats. It allows the insects to reproduce more rapidly. It provides a defense against predators. It allows the insects to migrate long distances.

fossil bird salamander 2. This fossil bird and this living salamander both have tails. However, they have different tail structures. The bird has a very short tail made of just one bone that helps it have a light skeleton for flying. The salamander has a long tail with many bones that helps it balance while it runs. What most likely explains why both the bird and salamander have tails and why the tails are different? a) The salamander and bird both inherited tails from a shared ancestor population, but this population separated into different environments. In each environment, different types of tails evolved, which helped the populations survive. It is impossible to explain the body structures of different species. The way that structures change over time is very complex, and no one has ever observed these changes occurring. The bird and salamander are different species, so they do not share an ancestor population. These species had separate ancestor populations, and each evolved a…
How are tripod fish and anglerfish similar? They both rest on the tips of their two pelvic fins and elaborate their tall fins, They both have long filaments that grow from the top of their heads. They both are highly stationary and lle in wait for their prey to come to them. They both have bloluminescent escas that emit light in the complete absence of sunlight.
60. text Some Characteristics of Lobster They can live up to 100 years. They are a family of marine crustaceans. Females carry approximately 8 000 eggs. From 50 000 eggs, only two lobsters reach adulthood. It takes approximately five to eight years to mature into adults. Lobsters shed once every two years to increase their body size. Females carry the eggs inside for 9 to 12 months and externally for another 9 to 12 months. Lobsters raised in aquaculture often eat each other and will require their claws to be banded. Newborn lobsters float near the water surface for four to six weeks without any protection from their parents. Lobster growth depends significantly on water temperature, food supply, water salinity, and depth of water. Three characteristics of lobsters that allow scientists to classify them as relatively K-selected organisms are Answer,Answer, and Answer.Record your answer in the lowest-to-highest numerical order.
