Ques: Answer the following question given this paragraph: gametes swim with the aid of their flagella to the female gametangium (the archegonium), and fertilization ensues. The zygote grows into a small sporophyte still attached to the parent gametophyte. It will give rise, by meiosis, to the next generation of spores. Liverwort plants can also reproduce asexually, by the breaking of branches or the spreading of leaf fragments called gemmae. In this latter type of reproduction, the gemmaesmall, intact, complete pieces of plant that are produced in a cup on the surface of the thallus (shown in Figure 25.11)are splashed out of the cup by raindrops. The gemmae then land nearby and develop into gametophytes. Q: Gametes swim with the aid of what structure to the female gametangium, and fertilization ensues? Choices: - oocyte - acrosome - nucleus - flagella A:
Ans: flagella

Ques:Answer the following question given this paragraph: which the articulating surfaces of the bones contact each other. Also unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly against each other, allowing for increased joint mobility. Q: Unlike fibrous or cartilaginous joints, the articulating bone surfaces at what joint type are not directly connected to each other with fibrous connective tissue or cartilage? Choices: - proximal joint - knee joint - polymeric joint - synovial joint A:

Ans:synovial joint
Ques: Answer the following question given this paragraph: Most metal objects are made of metal alloys rather than pure metals. Q: What are most metal objects made of? Choices: - tin - aluminum - bronze - metal alloys A:
