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? Choices: - Solar Power - energy fission - might fission - nuclear fission A:
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? Choices: - swim - digest - run - fly A:
(Answer)
fly
Ques: 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? Choices: - pod and eggs - eggs and pod - asexual reproduction - eggs and sperm A:
Ans: eggs and sperm
(Q).
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? Choices: - oocyte - acrosome - nucleus - flagella A:
(A).
flagella
Ques:Answer the following question given this paragraph: The patterns of atoms that make a mineral affect its physical properties. A mineral's crystal shape is determined by the way the atoms are arranged. For example, you can see how atoms are arranged in halite in Figure above . You can see how salt crystals look under a microscope in Figure below . Salt crystals are all cubes whether they're small or large. Q: A mineral's crystal shape is determined by the way what objects are arranged? Choices: - molecules - particles - Electrons - atoms A:

Ans:atoms
Ques:Answer the following question given this paragraph: Negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving around the nucleus. The region where an electron is most likely to be found is called an orbital. Q: What is the region called where an electron is most likely to be found? Choices: - the shell - the nucleus - the ellipse - the orbital A:

Ans:
the orbital
