Q: Answer the following question given this paragraph: Carrier proteins bind and carry the molecules across the cell membrane. These proteins bind a molecule on one side of the membrane, change shape as they carry the molecule across the membrane, and deposit the molecule on the other side of the membrane. Even though a protein is involved in both these methods of transport, neither method requires energy. Therefore these are still types of passive transport. Q: Carrier proteins bind and carry the molecules across what cell structure? A:

OPTIONS:
- nucleus
- cell wall
- plastid
- cell membrane

A: cell membrane

input: OPTIONS:
- endocrine system
- circulatory system
- renal system
- nervous system Now, answer this question: Answer the following question given this paragraph: Neural Regulation The nervous system plays a critical role in the regulation of vascular homeostasis. The primary regulatory sites include the cardiovascular centers in the brain that control both cardiac and vascular functions. In addition, more generalized neural responses from the limbic system and the autonomic nervous system are factors. Q: What system plays a critical role in the regulation of vascular homeostasis? A:
A:
output: nervous system

Answer the following question given this paragraph: The smallest and lightest alcohols (methanol, ethanol, propanol) are completely soluble in water in all proportions. In a solution, the hydroxyl groups of alcohol molecules and the water molecules form hydrogen bonds with each other, resulting in complete miscibility. However, as the length of the carbon chain increases, the solubility decreases. The solubility of 1-butanol is 7.4 g per 100 g of water, while that of 1-pentanol is 2.7 g per 100 g water, and 1-octanol is 0.06 g per 100 g water. The carbon chain portion of the larger alcohol molecule is nonpolar and leads to the decreased solubility of the overall compound. Q: The smallest and lightest alcohols (methanol, ethanol, propanol) are completely soluble in? A:
****
A: water

Problem:OPTIONS:
- invisible materials
- indestructible materials
- living materials
- nonliving materials

Answer the following question given this paragraph: Q: What do some animals use for shelter? A:
****
A:
nonliving materials
