The term that does not belong in the group.
Introduction :
Arthropods have complex organ systems that allow them to live in a variety of habitats. Adaptations to several organ systems, like the respiratory system and the nervous system, have contributed to the development of these animals. Insects make up the largest group of arthropods. They have three body segments and six legs. Grashoppers, bettles, butterflies, and lice are some members of class insecta.
Explanation of Solution
As insects develop, they undergo a series of changes in their body structure. This series of changes is known as metamorphosis. Insects that undergo metamorphosis usually undergo four stages on their way to adulthood: egg, larva, pupa and adult. The insects begin their lives as a fertilized egg, and they hatch into a larva.The larva is the insect's free-living wormlike stage. The pupa stage is a period of reorganization during which larva tissues and organs are broken down and replaced with adult tissues. After that the adult insect emerges from the pupa.
Nymph is one of the stages of incomplete metamorphosis. In this case, only three stages of development are involved- egg, nymph and adult. A nymph hatches from the egg and has the same general features as the adult but is smaller and may lack certain appendages and lack the ability to reproduce.
Castes are classes within a group of insects. The caste members have marked physiological differences within the species from those of other castes. For example, bees have castes such as workers, drones and queens, whose members are specially adapted to perform their particular role within the colony.
Thus, the term caste does not fit with the group as it is not a stage of development or growth in insects.
The term caste does not fit in with the group as it is a division within an insect group that performs specific functions for their survival.

Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forward

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forward
