Step by step
Solved in 2 steps
- Define the three types of embryo development and birth and give an example of a species for each: 1) Oviparous 2) Ovoviviparous 3) ViviparousHow do different types of energy investment by females contribute to the reproductive success of a frog, a chicken, and human? Drag the appropriate items to their respective bins. Reset Help embryos have gelatinous coat and lack internal membranes internal fertilization external fertilization embryos have internal membrane invest energy to the protection of their embryos by strong shells invest energy to the gamete production invest energy to the protection of their embryos by internal development Frog Chicken HumanThe animals that produce new young ones are known as: I. Oviparous II. Viviparous III. Both IV. None of these
- Could the number of eggs or young ones produced by an oviparous and viviparous mother be equal? Why?Female mammals undergo continuous reproductive cycles during their reproductive life. In the sense of offspring production, what is the benefit of these continuous cycles?What are some reproductive changes that may be adaptive in the face of parasitism? Why may males have higher rates of mortality due to parasites than females?
- Birds use which reproductive strategy? O oviparous reproduction O asexual reproduction O viviparous reproduction ovoviviparous reproduction OReproductive modes can be defined based on energetic provisioning (lechithotrophy vs. matritrophy) or birth style (ovipary vs. vivipary). Reproductive modes related to birth style mostly fall into clear categories of energetic provisioning. Define the above four reproductive modes based on energetics and style that make them distinct. Be sure to mention WHEN the relevant events related to each occur. Finally, explain why the birth style of ovovivipary less clearly falls into any one of these categories...Most lizards and snakes are oviparous, but some are ovoviviparous or have placental viviparity. Compare these methods of reproduc-tion in squamates. In what climate is viviparity most common?
