Answer the following question given this paragraph: Pollination must occur for fertilization to take place. Zygotes develop into embryos inside seeds, from which the next sporophyte generation grows. Q: What is a prerequisite for fertilization to take place in plants? Choices: - mitosis - photosynthesis - germination - pollination A:
pollination

Answer the following question given this paragraph: Biodiversity generally increases the productivity and stability of ecosystems. It helps ensure that at least some species will survive environmental change. It also provides many other ecosystem services. For example:. Q: What helps ensure that, at least, some species will survive environmental change? Choices: - reproduction - ecosystem - spontaneous mutation - biodiversity A:
(Answer)
biodiversity

(Q).
Answer the following question given this paragraph: Nearly all fish reproduce sexually, and most species have separate sexes. Those without separate sexes avoid self-fertilization by producing sperm and eggs at different times. Each fish typically produces a large number of gametes. In most fish species, fertilization takes place externally. These fish are oviparous. Eggs are laid and embryos develop outside the mother's body. In a minority of fish, including sharks, eggs develop inside the mother's body but without nourishment from the mother. These fish are ovoviviparous. Q: In ovoviviparous fish like shark, what develops inside the mother's body but without nourishment from the mother? Choices: - genes - spores - molecules - eggs A:
(A).
eggs
Ques:Answer the following question given this paragraph: Most air masses form over polar or tropical regions. They may form over continents or oceans. Air masses are moist if they form over oceans. They are dry if they form over continents. Air masses that form over oceans are called maritime air masses. Those that form over continents are called continental air masses. The image below shows air masses that form over or near North America ( Figure below ). Q: If an air mass forms over an ocean it is called what type of air mass? Choices: - cumulus - hurricane - tropical - maritime A:

Ans:maritime
Ques: Answer the following question given this paragraph: Describe at least two major changes to the animal phylogenetic tree that have come about due to molecular or genetic findings. How is it that morphological data alone might lead scientists to group animals into erroneous evolutionary relationships? 26. Briefly describe at least two theories that attempt to explain the cause of the Cambrian explosion. How is it that most, if not all, of the extant animal phyla today evolved during the Cambrian period if so many massive extinction events have taken place since then?. Q: Most, if not all, of the extant animal phyla today evolved during the cambrian period, yet many of what devastating events have taken place since then? Choices: - life extinctions - earthquakes - starvations - mass extinctions A:
Ans:
mass extinctions
