Answer the following question given this paragraph: Evolution focuses on past life forms and how they turned into present life forms. The history of life on Earth demonstrates how the first cells formed, turned into simple life forms, and then became more complex plants and animals. The studies of Charles Darwin have reshaped and influenced all aspects of biology. The vast amounts of evidence of evolution demonstrates the importance of the theory of evolution by natural selection. But has this process stopped? Of course not. Evolution does continue today. Q: What theory of evolution is charles darwin most known for? A:
****
A: natural selection

Answer the following question given this paragraph: Nuclear fusion is the opposite of nuclear fission. In fusion, two or more small nuclei combine to form a single, larger nucleus. An example is shown in Figure below . In this example, two hydrogen nuclei fuse to form a helium nucleus. A neutron and a great deal of energy are also released. In fact, fusion releases even more energy than fission does. Q: What is the opposite of nuclear fusion? A:
OPTIONS:
- Solar Power
- energy fission
- might fission
- nuclear fission
nuclear fission

Answer the following question given this paragraph: Bird organ systems are adapted for flight. For example, they have light-weight air-filled bones and a large four-chambered heart. Q: Light-weight air-filled bones and a large four-chambered heart helps a bird do what? A:
OPTIONS:
- swim
- digest
- run
- fly

Answer: fly

Question: Answer the following question given this paragraph: Most crustaceans have separate sexes, so they reproduce sexually using eggs and sperm. Many land crustaceans, such as the Christmas Island red crab, mate every season and return to the sea to release the eggs. Others, such as woodlice, lay their eggs on land when the environment is damp. In some crustaceans, the females keep the eggs until they hatch into free-swimming larvae. Q: Most crustaceans have separate sexes, so they reproduce sexually using what? A:
OPTIONS:
- pod and eggs
- eggs and pod
- asexual reproduction
- eggs and sperm
Answer: eggs and sperm

input with options: Answer the following question given this paragraph: gametes swim with the aid of their flagella to the female gametangium (the archegonium), and fertilization ensues. The zygote grows into a small sporophyte still attached to the parent gametophyte. It will give rise, by meiosis, to the next generation of spores. Liverwort plants can also reproduce asexually, by the breaking of branches or the spreading of leaf fragments called gemmae. In this latter type of reproduction, the gemmaesmall, intact, complete pieces of plant that are produced in a cup on the surface of the thallus (shown in Figure 25.11)are splashed out of the cup by raindrops. The gemmae then land nearby and develop into gametophytes. Q: Gametes swim with the aid of what structure to the female gametangium, and fertilization ensues? A:
OPTIONS:
- oocyte
- acrosome
- nucleus
- flagella
output: flagella

Problem: OPTIONS:
- starter crystal
- energy crystal
- fertilizer crystal
- seed crystal
Q: Answer the following question given this paragraph: Some solutes, such as sodium acetate, do not recrystallize easily. Suppose an exactly saturated solution of sodium acetate is prepared at 50C. As it cools back to room temperature, no crystals appear in the solution, even though the solubility of sodium acetate is lower at room temperature. A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal. The seed crystal provides a nucleation site on which the excess dissolved crystals can begin to grow. Recrystallization from a supersaturated solution is typically very fast. Q: What is used to recrystallize excess dissolved solute in a supersaturated solution? A:
Answer:
seed crystal
