Q: What is the term for a dynamic equilibrium that is maintained in body tissues and organs? Read this paragraph and choose the correct option from the provided answers: 33.3 Homeostasis Homeostasis is a dynamic equilibrium that is maintained in body tissues and organs. It is dynamic because it is constantly adjusting to the changes that the systems encounter. It is in equilibrium because body functions are kept within a normal range, with some fluctuations around a set point for the processes. Choices: - homogeneity - metabolism - dormancy - homeostasis A:
homeostasis

Q: What type of sunlight inhibits vertical growth in a plant? Read this paragraph and choose the correct option from the provided answers: Choices: - infrared - reduced - indirect - direct A:
direct

Q: Q: What is the ability of an atom to emit charged particles and energy from its nucleus called? Read this paragraph and choose the correct option from the provided answers: Radioactivity is the ability of an atom to emit charged particles and energy from its nucleus. The charged particles and energy are called by the general term radiation. Choices: - accumulation - conductivity - power - radioactivity A:
A: radioactivity

Question: Q: What form when a single atom gains or loses electrons? Read this paragraph and choose the correct option from the provided answers: Monatomic ions form when a single atom gains or loses electrons. For the main group elements, cations are generally formed by removing all of the valence electrons from the atom. Since the numbers of valence electrons for the representative elements are constant within a particular group, all we need is the group number of a given element to know its charge when it becomes a cation. Group 1 elements form ions with a 1+ charge, Group 2 metal ions have a 2+ charge, and the ions of Group 13 elements tend to have a 3+ charge. Heavier p-block metals such as tin and lead are special cases and will be discussed with the transition metal ions. The name of a monatomic cation is the same as the name of the neutral element. For example, the sodium atom (Na) loses a single electron to form the sodium ion (Na + ), while Al 3+ is an aluminum ion. Choices: - fusional ions - vacuoles ions - carbon atoms - monatomic ions A:
Answer: monatomic ions

Q: Plants can tell the time of day and time of year by sensing and using various wavelengths of what Read this paragraph and choose the correct option from the provided answers: Plant Responses to Light Plants have a number of sophisticated uses for light that go far beyond their ability to photosynthesize low-molecularweight sugars using only carbon dioxide, light, and water. Photomorphogenesis is the growth and development of plants in response to light. It allows plants to optimize their use of light and space. Photoperiodism is the ability to use light to track time. Plants can tell the time of day and time of year by sensing and using various wavelengths of sunlight. Phototropism is a directional response that allows plants to grow towards, or even away from, light. The sensing of light in the environment is important to plants; it can be crucial for competition and survival. The response of plants to light is mediated by different photoreceptors, which are comprised of a protein covalently bonded to a lightabsorbing pigment called a chromophore. Together, the two are called a chromoprotein. Choices: - moisture - lunar cycles - precipitation - sunlight A:
**Answer**
sunlight
