Answer the following question given this paragraph: 23.25 Fungal Reproduction Fungi can reproduce in two ways. Firstly, they make asexually produce through fragmentation. This occurs when pieces of hyphae are broken off, which then grow into new mycelia. The second method is by spores. Spores are lightweight structures and windblown designed to be transported over long distances and by many mediums, such as on the bodies of insects and birds. They are additionally light enough to be blown away for hundreds of kilometers. Spores may be asexual and sexual. Their sexual properties can be analysed to classify the four phylla of fungi. Q: Fungi reproduce asexually by fragmentation and either sexually or asexually via what lightweight, windblown structures? Choices: - lesions - seeds - ions - spores A:
spores
Answer the following question given this paragraph: Birds are endothermic tetrapod vertebrates. They are bipedal and have wings and feathers. Their organ systems are adapted for flight. For example, they have light-weight air-filled bones and a large four-chambered heart. Birds also have relatively large brains and a high level of intelligence. Q: In birds, lightweight air-filled bones and a large four-chambered heart are examples of adaptations for what purpose? Choices: - speed - long lifespan - mating - flight A:
flight
Q: Answer the following question given this paragraph: Pulmonary Ventilation The difference in pressures drives pulmonary ventilation because air flows down a pressure gradient, that is, air flows from an area of higher pressure to an area of lower pressure. Air flows into the lungs largely due to a difference in pressure; atmospheric pressure is greater than intra-alveolar pressure, and intra-alveolar pressure is greater than intrapleural pressure. Air flows out of the lungs during expiration based on the same principle; pressure within the lungs becomes greater than the atmospheric pressure. Pulmonary ventilation comprises two major steps: inspiration and expiration. Inspiration is the process that causes air to enter the lungs, and expiration is the process that causes air to leave the lungs (Figure 22.17). A respiratory cycle is one sequence of inspiration and expiration. In general, two muscle groups are used during normal inspiration: the diaphragm and the external intercostal muscles. Additional muscles can be used if a bigger breath is required. When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity. Due to the adhesive force of the pleural fluid, the expansion of the thoracic cavity forces the lungs to stretch and expand as well. This increase in volume leads to a decrease in intra-alveolar pressure, creating a pressure lower than atmospheric pressure. As a result, a pressure gradient is created that drives air into the lungs. Q: Air flows into the lungs largely due to a difference in what? Choices: - gravity - resistance - thrust - pressure A:
A: pressure
Question: Answer the following question given this paragraph: Sperm are released from the body during ejaculation . Ejaculation occurs when muscle contractions propel sperm from the epididymis. The sperm are forced through the ducts and out of the body through the urethra. As sperm travel through the ducts, they mix with fluids from the glands to form semen. Hundreds of millions of sperm are released with each ejaculation. Q: What is released from the body during ejaculation? Choices: - saliva - urine - blood - sperm A:
Answer: sperm

Answer the following question given this paragraph: Pneumonia is a disease in which some of the alveoli of the lungs fill with fluid so they can no longer exchange gas. Symptoms of pneumonia typically include coughing, chest pain, difficulty breathing, and fatigue. Pneumonia may be caused by an infection or an injury to the lungs. Q: What the name of the disease where some of the alveoli of the lungs fill with fluid so they can no longer exchange gas? Choices: - leukemia - lung cancer - emphysema - pneumonia A:
**Answer**
pneumonia
Answer the following question given this paragraph: Fungi are heterotrophs, meaning they obtain food from outside themselves. Q: Organisms that obtain food from outside themselves (i.e. they don't make their own food) are known as what? Choices: - autotrophs - zygotes - fungi - heterotrophs A:
heterotrophs
