Answer the following question given this paragraph: Eukaryotic cells also contain other organelles besides the nucleus. An organelle is a structure within the cytoplasm that performs a specific job in the cell. Organelles called mitochondria, for example, provide energy to the cell, and organelles called vacuoles store substances in the cell. Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Q: What is the term for a structure within the cytoplasm that performs a specific job in the cell? Choices: - mitochondria - nucleus - ribosome - organelle A:
(Answer)
organelle

Ans: heart

Answer the following question given this paragraph: A living cell is a system that is not in equilibrium with its surroundings; it requires a constant input of energy to maintain its nonequilibrium state. Cells maintain a low-entropy state by increasing the entropy of their surroundings. Aerobic organisms cannot survive in the absence of O2, whereas anaerobic organisms can live only in the absence of O2. Green plants and algae are phototrophs, which extract energy from the environment through a process called photosynthesis, the photochemical reduction of CO2 to a reduced carbon compound. Other species, called chemotrophs, extract energy from chemical compounds. One of the main processes chemotrophs use to obtain energy is respiration, which is the reverse of photosynthesis. Alternatively, some chemotrophs obtain energy byfermentation, in which an organic compound is both the oxidant and the reductant. Intermediates used by organisms to shuttle electrons between the reductant and the oxidant include NAD+ and NADH. Energy from the oxidation of nutrients is made available to cells through the synthesis of ATP, the energy currency of the cell. Its energy is used by cells to synthesize substances through coupled reactions and to perform work. The body stores energy as sugars, protein, or fats before using it to produce ATP. Q: What do chemotrophs extract energy from? Choices: - liquid compounds - carbon compounds - fatty compounds - chemical compounds A:
(A).
chemical compounds
Ques:Answer the following question given this paragraph: Water pollution happens when contaminants enter water bodies. Contaminants are any substances that harm the health of the environment or humans. Most contaminants enter the water because of humans. Surface water (river or lake) can be exposed to and contaminated by acid rain, storm water runoff, pesticide runoff, and industrial waste. This water is cleaned somewhat by exposure to sunlight, aeration, and microorganisms in the water. Groundwater (private wells and some public water supplies) generally takes longer to become contaminated, but the natural cleaning process also may take much longer. Groundwater can be contaminated by disease-producing pathogens, careless disposal of hazardous household chemical-containing products, agricultural chemicals, and leaking underground storage tanks. Q: What "kind" of water may take longer to become contaminated than surface water, while the natural cleaning process may take longer? Choices: - lake water - spring water - dam water - groundwater A:

Ans:groundwater
Answer the following question given this paragraph: In the Cell Cycle: Cancer (Advanced) concept, cancer is described as developing due to unregulated cell division. That is, cancer is a disease characterized by a population of cells that grow and divide without respect to normal limits. These cancerous cells invade and destroy adjacent tissues, and they may spread throughout the body. The process by which normal cells are transformed into cancer cells is known as carcinogenesis . This process is also known as oncogenesis or tumorigenesis. Oncogenes are mutated genes involved in the development of cancer. Q: Cancer develops when what process is unregulated? Choices: - metabolism - meiosis - cellular respiration - cell division A:
cell division
