Answer the following question given this paragraph: Evolution of Gene Regulation Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes. A nuclear region that contains the DNA was formed. Transcription and translation were physically separated into two different cellular compartments. It therefore became possible to control gene expression by regulating transcription in the nucleus, and also by controlling the RNA levels and protein translation present outside the nucleus. Some cellular processes arose from the need of the organism to defend itself. Cellular processes such as gene silencing developed to protect the cell from viral or parasitic infections. If the cell could quickly shut off gene expression for a short period of time, it would be able to survive an infection when other organisms could not. Therefore, the organism evolved a new process that helped it survive, and it was able to pass this new development to offspring. Q: Prokaryotic cells can only regulate gene expression by controlling the amount of what? A:

OPTIONS:
- folding
- translation
- RNA processing
- transcription

Answer: transcription

- vitamins
- hydrogen
- energy
Q: Answer the following question given this paragraph: At each level of a food chain, a lot of energy is lost. Only about 10 percent of the energy passes to the next level. Where does that energy go? Some energy is given off as heat. Some energy goes into animal wastes. Energy also goes into growing things that another consumer can't eat, like fur. It's because so much energy is lost that most food chains have just a few levels. There's not enough energy left for higher levels. Q: In a food chain, only about 10 percent of what passes to the next level? A:
Answer: energy

Problem:OPTIONS:
- atom
- capsule
- ovary
- ribosome

Answer the following question given this paragraph: A ribosome is a small organelle where proteins are made. It's like a factory in the cell. It gathers amino acids and joins them together into proteins. Unlike other organelles, the ribosome is not surrounded by a membrane. As a result, some scientists do not classify it as an organelle. Ribosomes may be found floating in the cytoplasm. Some ribosomes are located on the surface of another organelle, the endoplasmic reticulum. Q: What is the term for a small organelle where proteins are made? A:
****
A: ribosome

Answer the following question given this paragraph: Chemistry is the study of matter and energy and how they interact, mainly at the level of atoms and molecules. Basic concepts in chemistry include chemicals and chemical reactions. Q: Chemistry is the study of matter and energy and how they what? A:
OPTIONS:
- distinct
- division
- interaction
- interact
interact

Answer the following question given this paragraph: There are a variety of types of movable joints, which are illustrated in Figure below . The joints are classified by how they move. For example, a ball-and-socket joint, such as the shoulder, has the greatest range of motion, allowing movement in several directions. Other movable joints, including hinge joints such as the knee, allow less movement. Q: What type of joint has the greatest range of motion? A:
OPTIONS:
- Hinge
- Gliding
- Pivot
- ball-and-socket

Answer:
ball-and-socket
