Answer the following question given this paragraph: Communities are made up of populations of different species. In biology, a population is a group of organisms of the same species that live in the same area. The population is the unit of natural selection and evolution. How large a population is and how fast it is growing are often used as measures of its health. Q: What do you call a group of organisms of the same species that live in the same area? Choices: - system - ecosystem - biosphere - population A:
population
Answer the following question given this paragraph: Figure 4.11 Metabolic pathways are a series of reactions catalyzed by multiple enzymes. Feedback inhibition, where the end product of the pathway inhibits an upstream process, is an important regulatory mechanism in cells. Q: Metabolic pathways are a series of reactions catalyzed by multiple what? Choices: - hormones - vitamins - particles - enzymes A:
enzymes
Q: Answer the following question given this paragraph: When you look at the Moon from Earth, you notice dark and light areas. The maria are dark, solid, flat areas of lava. Maria covers around 16% of the Moon's surface, mostly on the near side. The maria formed about 3.0 to 3.5 billion years ago, when the Moon was continually bombarded by meteorites ( Figure below ). Large meteorites broke through the Moon's newly formed surface. This caused magma to flow out and fill the craters. Scientists estimate volcanic activity on the Moon ended about 1.2 billion years ago. Q: Covering about 16 percent of the moon's surface, maria are dark, solid, flat areas consisting of what substance? Choices: - debris - ash - dust - lava A:
A: lava
Question: Answer the following question given this paragraph: The population is an important unit in ecology as well as other biological sciences. How is a population defined, and what are the strengths and weaknesses of this definition? Are there some species that at certain times or places are not in populations?. Q: During interphase, the cell undergoes normal growth processes while also preparing for what, by accumulating energy and building blocks of dna? Choices: - proteins division - chromosome division - technology division - cell division A:
Answer: cell division

Answer the following question given this paragraph: Cartilage Templates Bone is a replacement tissue; that is, it uses a model tissue on which to lay down its mineral matrix. For skeletal development, the most common template is cartilage. During fetal development, a framework is laid down that determines where bones will form. This framework is a flexible, semi-solid matrix produced by chondroblasts and consists of hyaluronic acid, chondroitin sulfate, collagen fibers, and water. As the matrix surrounds and isolates chondroblasts, they are called chondrocytes. Unlike most connective tissues, cartilage is avascular, meaning that it has no blood vessels supplying nutrients and removing metabolic wastes. All of these functions are carried on by diffusion through the matrix. This is why damaged cartilage does not repair itself as readily as most tissues do. Throughout fetal development and into childhood growth and development, bone forms on the cartilaginous matrix. By the time a fetus is born, most of the cartilage has been replaced with bone. Some additional cartilage will be replaced throughout childhood, and some cartilage remains in the adult skeleton. Q: For skeletal development, the most common template is what? Choices: - calcium - membrane - collagen - cartilage A:
**Answer**
cartilage
