Answer the following question given this paragraph: The age of a rock in years is its absolute age. The main evidence for absolute age comes from radiometric dating methods, such as carbon-14 dating. These methods depend on radioactive decay. Q: Radiometric dating methods, such as carbon-14 dating depend on what type of decay? Choices: - microwave - carbon - nuclear - radioactive A:
radioactive
Answer the following question given this paragraph: Urine leaves the body through the urethra . Q: What does urine leave the body through? Choices: - vagina - colon - uterus - urethra A:
urethra
Q: Answer the following question given this paragraph: Annelids are divided into many repeating segments. The earthworm in Figure below is an annelid. You can clearly see its many segments. Segmentation of annelids is highly adaptive. Each segment has its own nerve and muscle tissues. This allows the animal to move very efficiently. Some segments can also be specialized to carry out particular functions. They may have special structures on them. For example, they might have tentacles for sensing or feeding, "paddles" for swimming, or suckers for clinging to surfaces. Q: What distinguishing characteristic of annelid anatomy shows specialization and adaptation? Choices: - asymmetry - beautiful - compression - segmentation A:
A: segmentation
Question: Answer the following question given this paragraph: Which of the following statements about mechanoreceptors is false? a. Pacini corpuscles are found in both glabrous and hairy skin. Merkel's disks are abundant on the fingertips and lips. Ruffini endings are encapsulated mechanoreceptors. Meissner's corpuscles extend into the lower dermis. Meissner's corpuscles, (shown in Figure 36.6) also known as tactile corpuscles, are found in the upper dermis, but they project into the epidermis. They, too, are found primarily in the glabrous skin on the fingertips and eyelids. They respond to fine touch and pressure, but they also respond to low-frequency vibration or flutter. They are rapidly adapting, fluid-filled, encapsulated neurons with small, well-defined borders and are responsive to fine details. Like Merkel's disks, Meissner's corpuscles are not as plentiful in the palms as they are in the fingertips. Q: Meissner's corpuscles are not as plentiful in the palms as they are in the what other part of the hand? Choices: - bones - fingernails - cuticles - fingertips A:
Answer: fingertips

Answer the following question given this paragraph: Plants are somewhat limited by temperature in terms of where they can grow. They need temperatures above freezing while they are actively growing. They also need light, carbon dioxide, and water. These substances are required for photosynthesis. Like most other living things, plants need oxygen. Oxygen is required for cellular respiration. In addition, plants need minerals. The minerals are required to make proteins and other organic molecules. Q: Photosynthesis requires light, water and what else? Choices: - seasons - nitrogen - soil - carbon dioxide A:
**Answer**
carbon dioxide
