Answer the following question given this paragraph: Whales and bats have the trait of echolocation. This is the ability to locate objects in the dark by bouncing sound waves off them. The most recent common ancestor of whales and bats did not have this trait. Apply lesson concepts to explain how the trait evolved in whales and bats. Q: What term is defined as the ability to locate objects in the dark by bouncing sound waves off them. Choices: - morphology - night vision - thermodynamics - echolocation A:
echolocation

Answer the following question given this paragraph: Flexion and Extension Flexion and extension are movements that take place within the sagittal plane and involve anterior or posterior movements of the body or limbs. For the vertebral column, flexion (anterior flexion) is an anterior (forward) bending of the neck or body, while extension involves a posterior-directed motion, such as straightening from a flexed position or bending backward. Lateral flexion is the bending of the neck or body toward the right or left side. These movements of the vertebral column involve both the symphysis joint formed by each intervertebral disc, as well as the plane type of synovial joint formed between the inferior articular processes of one vertebra and the superior articular processes of the next lower vertebra. In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension. Q: What type of flexion is the bending of the neck or body toward the right or left side? Choices: - orbital - cylindrical - ventral - lateral A:
**Answer**
lateral

Answer the following question given this paragraph: Sexual reproduction happens when a sperm and an egg cell combine together. This is called fertilization . Sperm are released into the vagina during sexual intercourse. They "swim" through the uterus and enter a fallopian tube . This is where fertilization normally takes place. Q: What happens when a sperm and an egg cell combine? Choices: - migration - manipulation - stimulation - fertilization A:
(Answer)
fertilization
