This suggests that the body cavity (coelum) evolved before the lophophore. Protostomes are one of the groups of animals having a true body cavity and are believed to share a common ancestor. They include annelids, mollusks, and arthropods. Lophophore is an organ characteristic of aquatic invertebrates (protostomes) that functions in filter feeding, it consists of a ridge of hollow tentacles bearing cilia, which waft food particles into the mouth.<span />
The lateral hypothalamus signals an animal to start eating, whereas the <span>ventromedial </span>hypothalamus signals the animal to stop eating. So the correct option is the first one.
2:
- cellular organization
- metabolism
- homeostasis
- hereditary
- growth and development
- response to stimuli
- adaptation to evolution
4: Photosynthesis
those are the ones I am pretty sure are correct, I am so sorry I haven't been in biology in so long :(
