Ques: Q: What happens to the length of the days in the fall? Read this paragraph and choose the correct option from the provided answers: For example, in the fall, when the days start to get shorter, the trees sense that there is less sunlight. The plant is stimulated, and it sends messages telling the leaves to change colors and fall. This is an example of photoperiodism , the reaction of organisms, such as plants, to the length of day or night. Photoperiodism is also the reaction of plants to the length of light and dark periods. Many flowering plants sense the length of night, a dark period, as a signal to flower. Each plant has a different photoperiod, or night length. When the plant senses the appropriate length of darkness, resulting in an appropriate length of daylight, it flowers. Flowering plants are classified as long-day plants or short-day plants. Long-day plants flower when the length of daylight exceeds the necessary photoperiod, and short-day plants flower when the day length is shorter than the necessary photoperiod. Long-day plants include carnations, clover, lettuce, wheat, and turnips. Short-day plants include cotton, rice, and sugar cane. Choices: - they stay the same - they change randomly - they get longer - they get shorter A:
Ans: they get shorter

Ques: Q: Which process helps deaminate amino acids? Read this paragraph and choose the correct option from the provided answers: The Fate of the Carbon Skeleton Any amino acid can be converted into an intermediate of the citric acid cycle. Once the amino group is removed, usually by transamination, the -keto acid that remains is catabolized by a pathway unique to that acid and consisting of one or more reactions. For example, phenylalanine undergoes a series of six reactions before it splits into. Choices: - deactivation - bromination - caramelization - transamination A:
Ans: transamination

Ques: Q: What make us sick when they become human parasites? Read this paragraph and choose the correct option from the provided answers: Most protist diseases in humans are caused by animal-like protists, or protozoa. Protozoa make us sick when they become human parasites. Three examples of parasitic protozoa are described below. Choices: - detritus - viruses - larvae - protozoa A:
Ans: protozoa

Ques: Q: What type of earthquake creates a tsunami? Read this paragraph and choose the correct option from the provided answers: An underwater earthquake creates a tsunami this way: the movement of the crust displaces water. The displacement forms a set of waves. The waves travel at jet speed through the ocean. Since the waves have low amplitudes and long wavelengths, they are unnoticed in deep water. As the waves reach shore they compress. They are also pushed upward by the shore. For these reasons, tsunamis can grow to enormous wave heights. Tsunami waves can cause tremendous destruction and loss of life. Fortunately, few undersea earthquakes generate tsunamis. Choices: - Tectonic - collapse - volcanic - underwater A:
Ans:
underwater
