Answer the following question given this paragraph: Most ecosystems get their energy from the Sun. Only producers can use sunlight to make usable energy. Producers convert the sunlight into chemical energy or food. Consumers get some of that energy when they eat producers. They also pass some of the energy on to other consumers when they are eaten. In this way, energy flows from one living thing to another. Q: Where do most ecosystems get their energy from? Choices: - earth - heat - water - sun A:
sun
Answer the following question given this paragraph: Using fossil fuels and nuclear energy creates other problems as well. The burning of fossil fuels releases carbon dioxide into the atmosphere. This is one of the major greenhouse gases causing global climate change. Nuclear power creates another set of problems, including the disposal of radioactive waste. Q: What gets released into the atmosphere when fossil fuels are burned? Choices: - oxygen - hydrogen - chemical dioxide - carbon dioxide A:
carbon dioxide
Q: 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:
A: cytokinesis
Question: Answer the following question given this paragraph: The Volvox sphere has a distinct front and back end. The colony of cells can swim in a coordinated fashion. The cells have eyespots, which are more developed in the cells near the front. This enables the colony to swim towards light. Q: What has a distinct front and back end? Choices: - hydro sphere - heroclix sphere - imipenem sphere - volvox sphere A:
Answer: volvox sphere

Answer the following question given this paragraph: Cephalochordata: Cephalochordates include the lancelets ( Figure below ), fish-like marine animals often found half-buried in the sand. Cephalochordates have a notochord and nerve cord but no backbone. Q: Cephalochordates have a notochord and nerve cord but not a? Choices: - digestive system - nervous system - brain - backbone A:
**Answer**
backbone

Answer the following question given this paragraph: Like other female vertebrates, all female mammals have ovaries. These are the organs that produce eggs (see Figure below ). Therian mammals also have two additional female reproductive structures that are not found in other vertebrates. They are the uterus and vagina. Q: The organs of female mammals that that produce eggs are called what? Choices: - testes - Uterus - fallopian tubes - ovaries A:
(A).
ovaries
