Answer the following question given this paragraph: Sometimes ecological succession occurs in areas where life has already existed. These areas already have soil full of nutrients. Secondary succession is the type of succession that happens after something destroys the habitat, such as a flood or other natural disaster. Abandoning a field that was once used for agriculture can also lead to secondary succession ( Figure below ). In this case, the pioneer species would be the grasses that first appear. Lichen would not be necessary as there is already nutrient-rich soil. Slowly, the field would return to its natural state. Q: What is the type of succession that happens after the destruction of a habitat? Choices: - primary succession - typical succession - tertiary succession - secondary succession A:
secondary succession
Answer the following question given this paragraph: Lycophytes follow the pattern of alternation of generations seen in the bryophytes, except that the sporophyte is the major stage of the lifecycle. The gametophytes do not depend on the sporophyte for nutrients. Some gametophytes develop underground and form mycorrhizal associations with fungi. In club mosses, the sporophyte gives rise to sporophylls arranged in strobili, cone-like structures that give the class its name. Lycophytes can be homosporous or heterosporous. Q: Some gametophytes develop underground and form mycorrhizal associations with what? Choices: - protists - plants - animals - fungi A:
fungi
Q: Answer the following question given this paragraph: To ensure that no more than one sperm fertilizes the egg, once the acrosomal reactions take place at one location of the egg membrane, the egg releases proteins in other locations to prevent other sperm from fusing with the egg. If this mechanism fails, multiple sperm can fuse with the egg, resulting in polyspermy. The resulting embryo is not genetically viable and dies within a few days. Q: What is the term for if multiple sperm fuse with an egg? Choices: - fraternization - in vitro fertilization - pollenation - polyspermy A:
A: polyspermy

Choices: - baby - childhood - toddler - infancy A:
Answer: infancy
