Answer the following question given this paragraph: The stirrup passes the amplified sound waves to the inner ear through the oval window (see Figure above ). When the oval window vibrates, it causes the cochlea to vibrate as well. The cochlea is a shell-like structure that is full of fluid and lined with nerve cells called hair cells. Each hair cell has tiny hair-like projections, as you can see in Figure below . When the cochlea vibrates, it causes waves in the fluid inside. The waves bend the "hairs" on the hair cells, and this triggers electrical impulses. The electrical impulses travel to the brain through nerves. Only after the nerve impulses reach the brain do we hear the sound. Q: The cochlea is a shell-like structure that is full of fluid and lined with nerve cells called what? Choices: - sperm cells - red cells - brain cells - hair cells A:
(Answer)
hair cells
Ques: Answer the following question given this paragraph: 31.3 Nutritional Adaptations of Plants Atmospheric nitrogen is the largest pool of available nitrogen in terrestrial ecosystems. However, plants cannot use this nitrogen because they do not have the necessary enzymes. Biological nitrogen fixation (BNF) is the conversion of atmospheric nitrogen to ammonia. The most important source of BNF is the symbiotic interaction between soil bacteria and legumes. The bacteria form nodules on the legume's roots in which nitrogen fixation takes place. Fungi form symbiotic associations (mycorrhizae) with plants, becoming integrated into the physical structure of the root. Through mycorrhization, the plant obtains minerals from the soil and the fungus obtains photosynthate from the plant root. Ectomycorrhizae form an extensive dense sheath around the root, while endomycorrhizae are embedded within the root tissue. Some plantsparasites, saprophytes, symbionts, epiphytes, and insectivoreshave evolved adaptations to obtain their organic or mineral nutrition from various sources. Q: What process refers to the conversion of atmospheric nitrogen to ammonia? Choices: - biological nutrient fixation - biological ammonia fixation - biological respiratory fixation - biological nitrogen fixation A:
Ans: biological nitrogen fixation
