Answer the following question given this paragraph: 26.3 Angiosperms Angiosperms are the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species. Most crops and ornamental plants are angiosperms. Their success comes from two innovative structures that protect reproduction from variability in the environment: the flower and the fruit. Flowers were derived from modified leaves. The main parts of a flower are the sepals and petals, which protect the reproductive parts: the stamens and the carpels. The stamens produce the male gametes in pollen grains. The carpels contain the female gametes (the eggs inside. Q: What is the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species? A:
OPTIONS:
- pteridophytes
- gymnosperms
- bryophytes
- angiosperms

Answer: angiosperms

Question: Answer the following question given this paragraph: The nucleus divides during mitosis, and the cytoplasm divides during cytokinesis. Q: When does the nucleus divide? A:
OPTIONS:
- meiosis
- photosynthesis
- epistasis
- mitosis
Answer: mitosis

input with options: Answer the following question given this paragraph: Organisms are organized in the microscopic level from atoms up to cells. The matter is structured in an ordered way. Atoms are arranged into molecules, then into macromolecules, which make up organelles, which work together to form cells. Beyond this, cells are organized in higher levels to form entire multicellular organisms, as shown in Figure below . Cells together form tissues, which make up organs, which are part of organ systems, which work together to form an entire organism. Of course, beyond this, organisms form populations which make up parts of an ecosystem. All of Earth's ecosystems together form the diverse environment that is Earth. Q: What bodily substance is formed from cells, and in turn helps make up organs? A:
OPTIONS:
- tendons
- muscles
- ligaments
- tissues
output: tissues

Q: Answer the following question given this paragraph: Coelacanths are ancient fish with just two living species. They are at risk of extinction because of their very small numbers. Q: Which ancient fish has just two living species and is at risk of extinction? A:

OPTIONS:
- latimeria
- hominids
- squids
- coelacanths

A: coelacanths

input: OPTIONS:
- nervous system
- digestive system
- Cardiovascular system
- skeletal system Now, answer this question: Answer the following question given this paragraph: The skeletal system protects the soft organs of the body. For example, the skull surrounds and protects the brain. The ribs protect the heart and lungs. Q: What system protects the soft organs of the body? A:
A:
output: skeletal system

Question: Answer the following question given this paragraph: Summary Nuclear reactions are accompanied by large changes in energy, which result in detectable changes in mass. The change in mass is related to the change in energy according to Einstein's equation: E = (m)c2. Large changes in energy are usually reported in kiloelectronvolts or megaelectronvolts (thousands or millions of electronvolts). With the exception of 1H, the experimentally determined mass of an atom is always less than the sum of the masses of the component particles (protons, neutrons, and electrons) by an amount called the mass defect of the nucleus. The energy corresponding to the mass defect is the nuclear binding energy, the amount of energy released when a nucleus forms from its component particles. In nuclear fission, nuclei split into lighter nuclei with an accompanying release of multiple neutrons and large amounts of energy. Thecritical mass is the minimum mass required to support a self-sustainingnuclear chain reaction. Nuclear fusion is a process in which two light nuclei combine to produce a heavier nucleus plus a great deal of energy. Q: In which process do two light nuclei combine to produce a heavier nucleus and great energy? A:
OPTIONS:
- general fusion
- light fusion
- certain fusion
- nuclear fusion
Answer:
nuclear fusion
