Solved in 2 steps
- 1. What did calcium ions do during fertilization in sea urchins?External fertilization occurs in which type of environment? aquatic forested savanna steppe1. What do you think is the reason why there is a diverse way of reproduction both in plants and animals? 2. Why do you think animals that undergo external fertilization live more likely in water than on land?
- 5)What is the primary purpose of the fertilization membrane? a)Provide the growing embryo with food b)Serve as a barrier to protect the zygote from the environment c)Prevent multiple sperm from attempting to merge with an egg d)Hold the cells together when the zygote begins undergoing cell division e)None of these options is correct1.What is the relationship of prolactin to hatching egg naturally? 2.What is the relationship between relative humidity and temperature inside the incubator compartment? 3.How does relative humidity effect embryonic devslopment? 4.What will happened to the developing embryo if all vents in the incubator are closed?why?2)Why are organisms that broadcast spawn useful for studying fertilization & development? a)Fertilization does not require multiple gametes b)Fertilization occurs outside the bodies of the parents, so it can be directly observed c)Fertilization is observable because the eggs are large enough to see d)Fertilization occurs without the need for parents
- 8. Compare and contrast animals with external fertilization to those with internal fertilization. What structures and/or behaviors would you expect to find in each type? What are the difference(s) in gamete production between the two types?C. Why do sea urchins have external fertilization? D. Then why don't the parents take care of the young? E. Because the urchin life involves two or more ecological niches, they are more susceptible to predation and exposure to environmental toxins. What environmental conditions, predators and toxins might they be exposed to at each stage?1. Predict the fertilization problems if the Ca+2 wave gets blocked?2. One of the goals of modern-day pharmacology is to develop a male contraceptive.Go through the steps of fertilization and determine what steps do you think it might be possible to block pharmacologically in order to produce such a contraceptive for males?
- 1. In Deuterostomes, nutrient molecules (monomers) are taken into the space between the endoderm and the ectoderm because a) the ectoderm makes protein for movement, b) the endoderm cells release hydrolytic enzymes that act on polymers, c) the endoderm releases enzymes that carry out dehydration synthesis of proteins. d) mRNA polymerase causes transcription. e) all are correct. 2.The Amoeba cell exhibits specialized abilities that enable it to react to a stimulus by producing a response or a behavior. It can do this because it has adapted properties exhibited by simpler more primitive cells. These cellular properties include a) Separation of the fluid environments inside and outside the cell. b) Active transport of Na+ out of and K+ into the cell, c) diffusion of Na+ in to and K+ out of a cell in reaction to a stimulus, d) the stimulus interacting with a receptor site in a membrane embedded protein, e) All of these are true.5. Outline the events of oogenesis. Why is oogenesis a significant process for egg production1. Why is it necessary for the egg to have changes leading to polyspermy block during fertilization? Discuss thoroughly and do no just copy from somewhere, please.
