Answer the following question given this paragraph: A general plant life cycle is represented by the diagram in Figure below . From the figure, you can see that the diploid sporophyte has a structure called a sporangium (plural, sporangia) that undergoes meiosis to form haploid spores. A spore develops into a haploid gametophyte. The gametophyte has male or female reproductive organs that undergo mitosis to form haploid gametes (sperm or eggs). Fertilization of gametes produces a diploid zygote. The zygote grows and develops into a mature sporophyte, and the cycle repeats. Q: What is the structure in a diploid sporophyte that undergoes meiosis to form haploid spores? Choices: - hymenium - dikaryotic - hyphae - sporangium A:
sporangium
Answer the following question given this paragraph: Digestion of Carbohydrates Carbohydrate digestion begins in the mouth (Figure 20.5 "The Principal Events and Sites of Carbohydrate Digestion"), where salivary -amylase attacks the -glycosidic linkages in starch, the main carbohydrate ingested by humans. Cleavage of the glycosidic linkages produces a mixture of dextrins, maltose, and glucose. (For more information about carbohydrates, see Chapter 16 "Carbohydrates". ) The -amylase mixed into the food remains active as the food passes through the esophagus, but it is rapidly inactivated in the acidic environment of the stomach. Figure 20.5 The Principal Events and Sites of Carbohydrate Digestion. Q: Where does carbohydrate digestion begin in the body? Choices: - stomach - intestines - throat - mouth A:
mouth
Q: Answer the following question given this paragraph: When gametes unite during fertilization, the resulting zygote inherits two alleles for each gene. One allele comes from each parent. Q: How many alleles comes from each parent? Choices: - none - two - three - one A:
A: one
Question: Answer the following question given this paragraph: Some animal-like protists use their "tails" to eat. These protists are called filter-feeders . They acquire nutrients by constantly whipping their tails, called flagellum , back and forth. The whipping of the flagellum creates a current that brings food into the protist. Q: Protists which use their tails to eat are called what? Choices: - swimmers - cycle - feeders - flagellators - filter-feeders A:
Answer: filter-feeders

Answer the following question given this paragraph: Fungus-like protists share many features with fungi. Like fungi, they are heterotrophs, meaning they must obtain food outside themselves. They also have cell walls and reproduce by forming spores, just like fungi. Fungus-like protists usually do not move, but a few develop movement at some point in their lives. Two major types of fungus-like protists are slime molds and water molds . Q: Two major types of fungus-like protists are slime molds and which other? Choices: - foul molds - green molds - black molds - water molds A:
**Answer**
water molds

**Answer**
interstitial fluid
