Q: Answer the following question given this paragraph: Chromosomes are coiled structures made of DNA and proteins. Chromosomes are the form of the genetic material of a cell during cell division. During other phases of the cell cycle, DNA is not coiled into chromosomes. Instead, it exists as a grainy material called chromatin . Q: What is the term for coiled structures made of dna and proteins? A:

OPTIONS:
- neutrons
- nodes
- platelets
- chromosomes

A: chromosomes

input: OPTIONS:
- gravitational field
- cloud cover
- ionosphere
- magnetic field Now, answer this question: Answer the following question given this paragraph: Figure 22.24 The Van Allen radiation belts are two regions in which energetic charged particles are trapped in the Earth's magnetic field. One belt lies about 300 km above the Earth's surface, the other about 16,000 km. Charged particles in these belts migrate along magnetic field lines and are partially reflected away from the poles by the stronger fields there. The charged particles that enter the atmosphere are replenished by the Sun and sources in deep outer space. Q: The van allen radiation belts are two regions in which energetic charged particles are trapped in earth's what? A:
A:
output: magnetic field

Answer the following question given this paragraph: Q: Worms use a hydrostatic type of what anatomical structure to move through their environment? A:

OPTIONS:
- gastrointestinal system
- head
- tail
- skeleton

Answer: skeleton

Problem: OPTIONS:
- nervous system
- immune system
- respiratory system
- circulatory system
Q: Answer the following question given this paragraph: Human organs are organized into organ systems. An organ system is a group of organs that work together to carry out a complex function. Each organ of the system does part of the overall job. For example, the heart is an organ in the circulatory system. The circulatory system also includes the blood vessels and blood. There are many different human organ systems. Figure below shows six of them and gives their functions. Q: The heart is an organ in which system? A:
Answer: circulatory system

Problem:OPTIONS:
- genes
- lipids
- peptides
- nucleotides

Answer the following question given this paragraph: (a) When pyrimidine or purine and a sugar react to form a glycosidic bond, a nucleoside is produced. Adding a phosphoric acid group to the sugar of a nucleoside produces a nucleotide. (b) Nucleotides link together to form long polymeric chains. A DNA molecule consists of two such chains held together by hydrogen bonding between the purine and pyrimidine components on different chains. Mutations in the DNA of an organism may lead to the synthesis of defective proteins. Phenylketonuria (PKU), for example, is a condition caused by a defective enzyme. Left. Q: What links together to form long polymeric chains? A:
****
A: nucleotides

Problem:OPTIONS:
- microwave
- atomic
- kinetic
- nuclear

Answer the following question given this paragraph: Nuclear energy is produced by splitting the nuclei of radioactive uranium. This doesn't release air pollution or carbon dioxide, but it does produce dangerous radioactive wastes. Q: What type of energy occurs by splitting the nuclei of radioactive uranium? A:
****
A:
nuclear
