Q: What are the active transport mechanisms by which molecules enter and leave the cell inside vesicles? Read this paragraph and choose the correct option from the provided answers: Endocytosis and exocytosis are active transport mechanisms in which large molecules enter and leave the cell inside vesicles. Choices: - endocytosis and oxidation - oxidation and exocytosis - dielectric and exocytosis - endocytosis and exocytosis A:
endocytosis and exocytosis

Q: What kind of solution might cause animal cells to burst? Read this paragraph and choose the correct option from the provided answers: Unless an animal cell (such as the red blood cell in the top panel) has an adaptation that allows it to alter the osmotic uptake of water, it will lose too much water and shrivel up in a hypertonic environment. If placed in a hypotonic solution, water molecules will enter the cell, causing it to swell and burst. Plant cells (bottom panel) become plasmolyzed in a hypertonic solution, but tend to do best in a hypotonic environment. Water is stored in the central vacuole of the plant cell. Choices: - Acid Solution - monatomic - eutrophic - hypotonic A:
hypotonic

Q: Q: How is carbon dioxide and water vapor that is produced by cellular respiration released? Read this paragraph and choose the correct option from the provided answers: A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation. Choices: - peroxidation - fermentation - evaporation - exhalation A:
A: exhalation

Question: Q: Nitrogen and sulfur oxides form what type of rain? Read this paragraph and choose the correct option from the provided answers: Both nitrogen and sulfur oxides are toxic to humans. These compounds can cause lung diseases or make them worse. Nitrogen and sulfur oxides form acid rain, which is described in the next concept. Choices: - common rain - toxic rain - heavy rain - acid rain A:
Answer: acid rain

Q: What is a mutation that changes all or much of a particular chromosome? Read this paragraph and choose the correct option from the provided answers: A mutation that changes all or a large part of a chromosome is called a chromosomal mutation. This type of mutation tends to be very serious. Sometimes chromosomes are missing or extra copies are present. An example is the mutation that causes Down syndrome. In this case, there is an extra copy of one of the chromosomes. Choices: - kinetic mutation - biochemical mutation - muscular mutation - chromosomal mutation A:
**Answer**
chromosomal mutation

Q: Q: Some bacteria also have tail-like structures called what? Read this paragraph and choose the correct option from the provided answers: Some bacteria also have tail-like structures called flagella ( Figure below ). Flagella help bacteria move. As the flagella rotate, they spin the bacteria and propel them forward. Though some eukaryotic cells do have a flagella, a flagella in eukaryotes is rare. Choices: - plasmids - sporangia - nuclei - flagella A:
A: flagella
