Q: Cilia and flagella are generally associated with what function in organisms, whether the function is internal or external? Read this paragraph and choose the correct option from the provided answers: Cilia ( cilium , singular) are made up of microtubule containing extensions of the cell membrane. Although both cilia and flagella are used for movement, cilia are much shorter than flagella. Cilia cover the surface of some single-celled organisms, such as paramecium. Their cilia beat together to move the little animal-like protists through the water. In multicellular animals, including humans, cilia are usually found in large numbers on a single surface of cells. Multicellular animals' cilia usually move materials inside the body. For example, the mucociliary escalator of the respiratory system is made up of mucus-secreting ciliated cells that line the trachea and bronchi. These ciliated cells, shown in Figure below , move mucus away from the lungs. This mucus catches spores, bacteria, and debris and moves to the esophagus, where it is swallowed. Choices: - digestion - reproduction - sight - movement A:
movement

Q: What category of food includes sugars, starches and fibers? Read this paragraph and choose the correct option from the provided answers: Carbohydrates include sugars, starches, and fiber. Sugars and starches are used by the body for energy. One gram of carbohydrates provides 4 Calories of energy. Fiber, which is found in plant foods, cannot be digested but is needed for good health. Simple carbohydrates are small carbohydrates found in foods such as fruits and milk. These carbohydrates include lactose, fructose and glucose. Complex carbohydrates are much larger molecules. Starch, which is a complex carbohydrate found in vegetables and grains, is made of thousands of glucose units bonded together. Choices: - enzymes - proteins - alcohols - carbohydrates A:
carbohydrates

Q: Q: Although it is the easiest to observe, what property is not ideal as a sole way to identify minerals? Read this paragraph and choose the correct option from the provided answers: Color is probably the easiest property to observe. Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a golden color and think it is gold. But it might actually be pyrite, or "fool's gold," which is made of iron and sulfide. It contains no gold atoms. Choices: - temperature - density - composition - color A:
A: color

Question: Q: How many chromosomes do bacterial dna have? Read this paragraph and choose the correct option from the provided answers: Bacteria lack many of the structures that eukaryotic cells contain. For example, they don't have a nucleus. They also lack membrane-bound organelles, such as mitochondria or chloroplasts. The DNA of a bacterial cell is also different from a eukaryotic cell. Bacterial DNA is contained in one circular chromosome, located in the cytoplasm. Eukaryotes have several linear chromosomes. Bacteria also have two additional unique features: a cell wall and flagella. Some bacteria also have a capsule outside the cell wall. Choices: - one rectangular chromosome - one triangular chromosome - one simple chromosome - one circular chromosome A:
Answer: one circular chromosome

*Question*
Q: What is the minimum number of times a partial lunar eclipse will occur each year? Read this paragraph and choose the correct option from the provided answers: Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The Moon glows with a dull red coloring during a total lunar eclipse ( Figure below ). Choices: - six - 11 - five - two A:
**Answer**
two

(Q).
Q: The cochlea is a shell-like structure that is full of fluid and lined with nerve cells called what? Read this paragraph and choose the correct option from the provided answers: The stirrup passes the amplified sound waves to the inner ear through the oval window (see Figure above ). When the oval window vibrates, it causes the cochlea to vibrate as well. The cochlea is a shell-like structure that is full of fluid and lined with nerve cells called hair cells. Each hair cell has tiny hair-like projections, as you can see in Figure below . When the cochlea vibrates, it causes waves in the fluid inside. The waves bend the "hairs" on the hair cells, and this triggers electrical impulses. The electrical impulses travel to the brain through nerves. Only after the nerve impulses reach the brain do we hear the sound. Choices: - sperm cells - red cells - brain cells - hair cells A:
(A).
hair cells
