Answer the following question given this paragraph: The cell is the smallest unit of structure and function of all living organisms. A cell is also the smallest unit of life, with single-celled organisms present on this planet for over 3.5 billion years. Single-celled ( unicellular ) organisms like bacteria are obviously composed of just one cell, whereas multicellular organisms can be composed of trillions of cells. Multicellular organisms include protists (though single-celled protists also exist), fungi, plants and animals. Most plant and animal cells are between 1 and 100 m and therefore can only be observed under the microscope. Q: What is the smallest unit of structure and function of all living organisms? A:
****
A: the cell

Answer the following question given this paragraph: Autism has a wide phenotypic spectrum of disability. Twin studies have been instrumental in demonstrating an environmental component in autism. Q: Twin studies have been instrumental in demonstrating what type of component in autism? A:
OPTIONS:
- internal
- bacterial
- natural
- environmental
environmental

Answer the following question given this paragraph: A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane. Gated channels have a binding site that is specific for a given molecule or ion. A stimulus causes the "gate" to open or shut. The stimulus may be chemical or electrical signals, temperature, or mechanical force, depending on the type of gated channel. For example, the sodium gated channels of a nerve cell are stimulated by a chemical signal which causes them to open and allow sodium ions into the cell. Glucose molecules are too big to diffuse through the plasma membrane easily, so they are moved across the membrane through gated channels. In this way glucose diffuses very quickly across a cell membrane, which is important because many cells depend on glucose for energy. Q: What do many cells depend on glucose for? A:
OPTIONS:
- food
- heating
- osmosis
- energy

Answer: energy

Question: Answer the following question given this paragraph: Enzymes are involved in most of the biochemical reactions that take place in organisms. About 4,000 such reactions are known to be catalyzed by enzymes, but the number may be even higher. Enzymes allow reactions to occur at the rate necessary for life. Q: What substances serve as catalysts in most of the biochemical reactions that take place in organisms? A:
OPTIONS:
- hormones
- carbohydrates
- iseotrops
- enzymes
Answer: enzymes

input with options: Answer the following question given this paragraph: 35.3 | The Central Nervous System By the end of this section, you will be able to: Identify the spinal cord, cerebral lobes, and other brain areas on a diagram of the brain Describe the basic functions of the spinal cord, cerebral lobes, and other brain areas The central nervous system (CNS) is made up of the brain, a part of which is shown in Figure 35.19 and spinal cord and is covered with three layers of protective coverings called meninges (from the Greek word for membrane). The outermost layer is the dura mater (Latin for "hard mother"). As the Latin suggests, the primary function for this thick layer is to protect the brain and spinal cord. The dura mater also contains vein-like structures that carry blood from the brain back to the heart. The middle layer is the web-like arachnoid mater. The last layer is the pia mater (Latin for "soft mother"), which directly contacts and covers the brain and spinal cord like plastic wrap. The space between the arachnoid and pia maters is filled with cerebrospinal fluid (CSF). CSF is produced by a tissue called choroid plexus in fluid-filled compartments in the CNS called ventricles. The brain floats in CSF, which acts as a cushion and shock absorber and makes the brain neutrally buoyant. CSF also functions to circulate chemical substances throughout the brain and into the spinal cord. Q: The three layers of protective coverings of the spinal cord is called what? A:
OPTIONS:
- dermis
- tendons
- muscles
- meninges
output: meninges

Problem: OPTIONS:
- Europe
- inland
- Ocean
- antarctica
Q: Answer the following question given this paragraph: The pauropods are typically 0.5-2.0 mm long and live on all continents except Antarctica. They are usually found in soil, leaf litter, or other moist places. They feed on fungi and decaying organic matter, and are essentially harmless. Adult pauropods have 11 or 12 body segments and 9-11 pairs of legs. They also possess unique forked antennae and a distinctive pattern of movement characterized by rapid burst of movement and frequent abrupt changes in direction. Over 700 species have been described, and they are believed to be closely related to millipedes. Q: Pauropods, presumed relatives of millipedes usually found in soil, leaf litter and other moist places, live on all continents except what? A:
Answer:
antarctica
