Answer the following question given this paragraph: A N SW E R S 1. Gases consist of tiny particles of matter that are in constant motion. Gas particles are constantly colliding with each other and the walls of a container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are separated by large distances, with the size of a gas particle tiny compared to the distances that separate them. There are no interactive forces (i. , attraction or repulsion) between the particles of a gas. The average speed of gas particles is dependent on the temperature of the gas. Q: Gas particles are constantly colliding with each other and the walls of a container, and these collisions are elastic, so there is no net loss of what? A:
****
A: energy

Answer the following question given this paragraph: Chapter 11 1 Figure 11.9 Yes, it will be able to reproduce asexually. 2 C 4 D 6 C 8 C 10 C 12 B 14 During the meiotic interphase, each chromosome is duplicated. The sister chromatids that are formed during synthesis are held together at the centromere region by cohesin proteins. All chromosomes are attached to the nuclear envelope by their tips. As the cell enters prophase I, the nuclear envelope begins to fragment, and the proteins holding homologous chromosomes locate each other. The four sister chromatids align lengthwise, and a protein lattice called the synaptonemal complex is formed between them to bind them together. The synaptonemal complex facilitates crossover between non-sister chromatids, which is observed as chiasmata along the length of the chromosome. As prophase I progresses, the synaptonemal complex breaks down and the sister chromatids become free, except where they are attached by chiasmata. At this stage, the four chromatids are visible in each homologous pairing and are called a tetrad. 16 In metaphase I, the homologous chromosomes line up at the metaphase plate. In anaphase I, the homologous chromosomes are pulled apart and move to opposite poles. Sister chromatids are not separated until meiosis II. The fused kinetochore formed during meiosis I ensures that each spindle microtubule that binds to the tetrad will attach to both sister chromatids. 18 a. Crossover occurs in prophase I between non-sister homologous chromosomes. Segments of DNA are exchanged between maternally derived and paternally derived chromosomes, and new gene combinations are formed. Random alignment during metaphase I leads to gametes that have a mixture of maternal and paternal chromosomes. Fertilization is random, in that any two gametes can fuse. Q: During interphase of what process, each chromosome is duplicated, and the sister chromatids formed during synthesis are held together at the centromere region by cohesin proteins? A:
OPTIONS:
- mitosis
- apoptosis
- digestion
- meiosis
meiosis

Answer the following question given this paragraph: Algae are like plants mainly because they contain chloroplasts. This allows them to make food by photosynthesis. Algae are important producers in water-based ecosystems such as the ocean. On the other hand, algae lack other plant structures. For example, they don't have roots, stems, or leaves. Also unlike plants, some algae can move. They may move with pseudopods or flagella. Q: Algae are like plants mainly because they contain what? A:
OPTIONS:
- organelles
- cells
- cell wall
- chloroplasts

Answer: chloroplasts

Question: Answer the following question given this paragraph: Unlike Mendel's peas, people do not all fall into two categories: short or tall. Most people, in fact, are somewhere in between. Obviously, Mendel's rules are too simple to explain the inheritance of human height. Q: Whose rules are too simple to explain the inheritance of human height? A:
OPTIONS:
- Einstein
- Pascal
- Darwin
- mendel
Answer: mendel

input with options: Answer the following question given this paragraph: Most vascular plants are seed plants, or spermatophytes. They reproduce with seeds and pollen. Some modern seed plants are gymnosperms that produce seeds in cones. Q: What is the term for seed plants? A:
OPTIONS:
- sporozoans
- proteins
- germospores
- spermatophytes
output: spermatophytes

Problem: OPTIONS:

Q: Answer the following question given this paragraph: Depending on the surrounding conditions, normal matter usually exists as one of three phases: solid, liquid, or gas. A phase change is a physical process in which a substance goes from one phase to another. Usually the change occurs when adding or removing heat at a particular temperature, known as the melting point or the boiling point of the substance. The melting point is the temperature at which the substance goes from a solid to a liquid (or from a liquid to a solid). The boiling point is the temperature at which a substance goes from a liquid to a gas (or from a gas to a liquid). The nature of the phase change depends on the direction of the heat transfer. Heat going into a substance changes it from a solid to a liquid or a liquid to a gas. Removing heat from a substance changes a gas to a liquid or a liquid to a solid. Two key points are worth emphasizing. First, at a substance's melting point or boiling point, two phases can exist simultaneously. Take water (H2O) as an example.
