Question

1.1 list two functions of the corona in rotifers.
1.
2.
1.2 can you see any toes on the foot of your specimen? how many?
1.3 why is parthenogenesis categorized as a type of asexual reproduction?
1.4 list several features of spiny - headed worms that suggest adaptation to a parasitic lifestyle.
1.5 which organs occupy the majority of the body space of the spiny - headed worm? explain why this is the case.

Explanation:

1.1 The corona in rotifers is used for locomotion and feeding. It has cilia that create water - currents for movement and to bring in food particles.
1.2 This requires actual specimen observation. Without seeing the specimen, an answer cannot be provided.
1.3 Parthenogenesis is asexual reproduction because it involves the development of an embryo from an unfertilized egg, without the fusion of gametes from two parents.
1.4 Spiny - headed worms have features like hooks and spines on their proboscis for attachment to the host, a simple digestive system as they absorb nutrients from the host, and a high reproductive capacity to ensure survival in the host environment.
1.5 Reproductive organs often occupy the majority of the body space in spiny - headed worms. This is because their main biological goal is reproduction, and they need to produce a large number of eggs to increase the chances of their species' survival and spread.

Answer:

1.1 Locomotion; Feeding
1.2 Cannot be determined without specimen observation
1.3 Development from unfertilized egg without gamete fusion
1.4 Hooks and spines on proboscis, simple digestive system, high reproductive capacity
1.5 Reproductive organs; To maximize egg - production for species survival
