Answer the following question given this paragraph: Agents of Decomposition The fungus-like protist saprobes are specialized to absorb nutrients from nonliving organic matter, such as dead organisms or their wastes. For instance, many types of oomycetes grow on dead animals or algae. Saprobic protists have the essential function of returning inorganic nutrients to the soil and water. This process allows for new plant growth, which in turn generates sustenance for other organisms along the food chain. Indeed, without saprobe species, such as protists, fungi, and bacteria, life would cease to exist as all organic carbon became "tied up" in dead organisms. Q: Fungus-like protist saprobes play what role in a food chain and are specialized to absorb nutrients from nonliving organic matter, such as dead organisms or their wastes? Choices: - aphids - Soil - fluxes - decomposers A:
decomposers
Answer the following question given this paragraph: possess a single, undivided lobe. Eutherian mammals also possess a specialized structure that links the two cerebral hemispheres, called the corpus callosum. Q: Eutherian mammals possess a specialized structure called the corpus callosum that links what hemispheres? Choices: - cortical - appendages - spatial - cerebral A:
cerebral
Q: Answer the following question given this paragraph: Hair is one of the defining characteristics of mammals. In fact, mammals are the only animals to have hair. Hair sticks out from the epidermis, but it grows from the dermis ( Figure below ). Hair grows from inside the hair follicle . New cells grow in the bottom part of the hair, called the bulb. Older cells get pushed up, and the hair grows longer. The cells that make up the hair strand are dead and filled with the rope-like protein keratin. Q: Hair sticks out from the epidermis, but it grows from the? Choices: - humus - fat - bone - dermis A:
A: dermis
Question: Answer the following question given this paragraph: Lysosomes, which use enzymes to break down foreign matter and dead cells. Q: What use enzymes to break down foreign matter and dead cells? Choices: - lipids - hormones - lymphocytes - lysosomes A:
Answer: lysosomes

The leading hypothesis for how they formed is called the nebular hypothesis . Q: Approximately how many billion years ago did our solar system begin? Choices: - four billion - three billion - nine billion - five billion A:
**Answer**
five billion

Answer the following question given this paragraph: During mitosis , the nucleus divides as the chromosomes are equally separated. One nucleus becomes two nuclei, each with an identical set of chromosomes . Mitosis is followed by cytokinesis , when the cytoplasm divides, resulting in two cells. After cytokinesis, cell division is complete. The one parent cell (the dividing cell) forms two genetically identical daughter cells (the cells that divide from the parent cell). The term "genetically identical" means that each cell has an identical set of DNA, and this DNA is also identical to that of the parent cell. If the cell cycle is not carefully controlled, it can cause a disease called cancer in which the cells divide out of control. A tumor can result from this kind of growth. Q: The cytoplasm divides during what process? Choices: - metamorphosis - osmosis - genesys - cytokinesis A:
(Answer)
cytokinesis
