23. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






24. Controls hunger and thirst






25. All store energy within their chemical bonds.






26. Enzymes are usually __________ to certain reactions.






27. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






28. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






29. The vocal cords are found in the larynx.






30. Layer that will become the gut lining as well as some accessory structures.






31. It secretes saliva which enters the digestive tract and aids the digestive process.






32. Covalent bonds






33. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.

37. The phylum of insects (bees).






38. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






39. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).
