Q: Answer the following question given this paragraph: 16.7 | Cancer and Gene Regulation By the end of this section, you will be able to: Describe how changes to gene expression can cause cancer Explain how changes to gene expression at different levels can disrupt the cell cycle Discuss how understanding regulation of gene expression can lead to better drug design Cancer is not a single disease but includes many different diseases. In cancer cells, mutations modify cell-cycle control and cells don't stop growing as they normally would. Mutations can also alter the growth rate or the progression of the cell through the cell cycle. One example of a gene modification that alters the growth rate is increased phosphorylation of cyclin B, a protein that controls the progression of a cell through the cell cycle and serves as a cell-cycle checkpoint protein. For cells to move through each phase of the cell cycle, the cell must pass through checkpoints. This ensures that the cell has properly completed the step and has not encountered any mutation that will alter its function. Many proteins, including cyclin B, control these checkpoints. The phosphorylation of cyclin B, a post-translational event, alters its function. As a result, cells can progress through the cell cycle unimpeded, even if mutations exist in the cell and its growth should be terminated. This post-translational change of cyclin B prevents it from controlling the cell cycle and contributes to the development of cancer. Q: Cancer involves what changes that modify cell-cycle control and alter the growth rate or progression of the cell through the cell cycle? A:

OPTIONS:
- deletions
- enhancements
- stabilization
- mutations

A: mutations

input: OPTIONS:
- metastasis and biotic
- innate and biotic
- hygroscopic and abiotic
- abiotic and biotic Now, answer this question: Answer the following question given this paragraph: The abiotic factors, such as the amount of rainfall and the temperature, are going to influence other abiotic factors, such as the quality of the soil. This, in turn, is going to influence the plants that migrate into the ecosystem and thrive in that biome. Recall that migration is the movement of an organism into or out of a population. It can also refer to a whole new species moving into a habitat . The type of plants that live in a biome are going to attract a certain type of animal to that habitat. It is the interaction of the abiotic and biotic factors that describe a biome and ecosystem. In aquatic biomes, abiotic factors such as salt, sunlight and temperature play significant roles. Q: The interaction of what opposite factors describe a biome and ecosystem? A:
A:
output: abiotic and biotic

Answer the following question given this paragraph: Some lipids contain the element phosphorus as well as carbon, hydrogen, and oxygen. These lipids are called phospholipids. Two layers of phospholipid molecules make up the cell membranes of living things. In the Figure below , you can see how phospholipid molecules are arranged in a cell membrane. Q: What type of lipids contain the element phosphorus, carbon, hydrogen and oxygen? A:

OPTIONS:
- filaments
- eukaryotes
- alleles
- phospholipids

Answer: phospholipids

Problem: OPTIONS:
- river bank
- artesian well
- culvert
- aquifer
Q: Answer the following question given this paragraph: An aquifer is a saturated layer of rock or soil. Q: What is defined as a saturated layer of rock or soil? A:
Answer: aquifer

Answer the following question given this paragraph: 9.5 | Types of Body Movements By the end of this section, you will be able to: Define the different types of body movements Identify the joints that allow for these motions Synovial joints allow the body a tremendous range of movements. Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation. The type of movement that can be produced at a synovial joint is determined by its structural type. While the ball-and-socket joint gives the greatest range of movement at an individual joint, in other regions of the body, several joints may work together to produce a particular movement. Overall, each type of synovial joint is necessary to provide the body with its great flexibility and mobility. There are many types of movement that can occur at synovial joints (Table 9.1). Movement types are generally paired, with one being the opposite of the other. Body movements are always described in relation to the anatomical position of the body: upright stance, with upper limbs to the side of body and palms facing forward. Refer to Figure 9.12 as you go through this section. Q: Synovial and ball-and-socket are both types of what? A:

OPTIONS:
- bonds
- cells
- muscles
- joints

Answer:
joints
