Problem: OPTIONS:
- hip socket
- meniscus
- femur joint
- hip joint
Q: Answer the following question given this paragraph: 11.6 Appendicular Muscles of the Pelvic Girdle and Lower Limbs The pelvic girdle attaches the legs to the axial skeleton. The hip joint is where the pelvic girdle and the leg come together. The hip is joined to the pelvic girdle by many muscles. In the gluteal region, the psoas major and iliacus form the iliopsoas. The large and strong gluteus maximus, gluteus medius, and gluteus minimus extend and abduct the femur. Along with the gluteus maximus, the tensor fascia lata muscle forms the iliotibial tract. The lateral rotators of the femur at the hip are the piriformis, obturator internus, obturator externus, superior gemellus, inferior gemellus, and quadratus femoris. On the medial part of the thigh, the adductor longus, adductor brevis, and adductor magnus adduct the thigh and medially rotate it. The pectineus muscle adducts and flexes the femur at the hip. The thigh muscles that move the femur, tibia, and fibula are divided into medial, anterior, and posterior compartments. The medial compartment includes the adductors, pectineus, and the gracilis. The anterior compartment comprises the quadriceps femoris, quadriceps tendon, patellar ligament, and the sartorius. The quadriceps femoris is made of four muscles: the rectus femoris, the vastus lateralis, the vastus medius, and the vastus intermedius, which together extend the knee. The posterior compartment of the thigh includes the hamstrings: the biceps femoris, semitendinosus, and the semimembranosus, which all flex the knee. The muscles of the leg that move the foot and toes are divided into anterior, lateral, superficial- and deep-posterior compartments. The anterior compartment includes the tibialis anterior, the extensor hallucis longus, the extensor digitorum longus, and the fibularis (peroneus) tertius. The lateral compartment houses the fibularis (peroneus) longus and the fibularis (peroneus) brevis. The superficial posterior compartment has the gastrocnemius, soleus, and plantaris; and the deep posterior compartment has the popliteus, tibialis... Q: What is the joint where the pelvic girdle and leg come together? A:
Answer: hip joint

Problem:OPTIONS:
- paradox species
- symbiotic species
- complement species
- keystone species

Answer the following question given this paragraph: Some predator species play a special role in their community. They are called keystone species. When the population size of a keystone species changes, the populations of many other species are affected. Prairie dogs, pictured in Figure below , are an example of a keystone species. Their numbers affect most of the other species in their community. Prairie dog actions improve the quality of soil and water for plants, upon which most other species in the community depend. Q: What do you call a predator species that affects other species' populations when its own population size changes? A:
****
A: keystone species

Answer the following question given this paragraph: When bacteria are destroyed by leukocytes, pyrogens are released into the blood. Pyrogens reset the body's thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise?. Q: When bacteria are destroyed by leukocytes, what are released into the blood? A:
OPTIONS:
- carcinogens
- proteins
- sporozoans
- pyrogens
pyrogens

Answer the following question given this paragraph: Q: What chemical substances are secreted by animals that communicate by odor or taste? A:
OPTIONS:
- alaki
- hormones
- acids
- pheromones

Answer: pheromones

Question: Answer the following question given this paragraph: Q: Endotherms are warmed mostly by heat generated by what? A:
OPTIONS:
- movement
- electricity
- the sun
- metabolism
Answer: metabolism

input: OPTIONS:
- sea floor
- sand
- beaches
- reef or rock Now, answer this question: Answer the following question given this paragraph: Sponges are a source of food for many species of fish. Because sponges are anchored to a reef or rock, they can't run away from predators. However, their sharp spicules provide some defense. They also produce toxins that may poison predators that try to eat them. Q: Where are sponges most likely anchored to? A:
A:
output:
reef or rock
