Answer the following question given this paragraph: into the brain, and the posterior region becomes the spinal cord. Tissues at the edges of the neural groove, when it closes off, are called the neural crest and migrate through the embryo to give rise to PNS structures as well as some non-nervous tissues. The brain develops from this early tube structure and gives rise to specific regions of the adult brain. As the neural tube grows and differentiates, it enlarges into three vesicles that correspond to the forebrain, midbrain, and hindbrain regions of the adult brain. Later in development, two of these three vesicles differentiate further, resulting in five vesicles. Those five vesicles can be aligned with the four major regions of the adult brain. The cerebrum is formed directly from the telencephalon. The diencephalon is the only region that keeps its embryonic name. The mesencephalon, metencephalon, and myelencephalon become the brain stem. The cerebellum also develops from the metencephalon and is a separate region of the adult brain. The spinal cord develops out of the rest of the neural tube and retains the tube structure, with the nervous tissue thickening and the hollow center becoming a very small central canal through the cord. The rest of the hollow center of the neural tube corresponds to open spaces within the brain called the ventricles, where cerebrospinal fluid is found. Q: The brain develops from this early tube structure and gives rise to specific regions of the adult brain. as the neural tube grows and differentiates, it enlarges into three vesicles that correspond to the forebrain, midbrain, and this? Choices: - anteriorbrain - rearbrain - astrobrain - hindbrain A:
hindbrain
Q: Answer the following question given this paragraph: Flame Cells of Planaria and Nephridia of Worms As multi-cellular systems evolved to have organ systems that divided the metabolic needs of the body, individual organs evolved to perform the excretory function. Planaria are flatworms that live in fresh water. Their excretory system consists of two tubules connected to a highly branched duct system. The cells in the tubules are called flame cells (or protonephridia) because they have a cluster of cilia that looks like a flickering flame when viewed under the microscope, as illustrated in Figure 41.10a. The cilia propel waste matter down the tubules and out of the body through excretory pores that open on the body surface; cilia also draw water from the interstitial fluid, allowing for filtration. Any valuable metabolites are recovered by reabsorption. Flame cells are found in flatworms, including parasitic tapeworms and free-living planaria. They also maintain the organism's osmotic balance. Q: How are valuable metabolites recovered? Choices: - replication reaction - osmosis - metabolism - reabsorption A:
A: reabsorption
Question: Answer the following question given this paragraph: Because air is a gas, its molecules have a lot of energy. Air molecules move a lot and bump into things. For this reason, they exert pressure. Air pressure is defined as the weight of the air pressing against a given area. Q: Air is an example of what state of matter? Choices: - solid - liquid - plasma - gas A:
Answer: gas
*Question*
Answer the following question given this paragraph: Topographic maps that show water depths are called bathymetric maps . An example of one is pictured below ( Figure below ). Bathymetric maps are made of any water body, including lakes and oceans. On these maps, the contour lines represent depth below the surface. Therefore, high numbers are deeper depths and low numbers are shallow depths. Q: What are topographic maps that show water depths called? Choices: - solenoid maps - morainic maps - Water Table maps - bathymetric maps A:
**Answer**
bathymetric maps
Answer the following question given this paragraph: Making healthy lifestyle choices can help prevent some types of cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen (see Figure below ). Q: Choosing to not smoke and using sunscreen are examples of lifestyle choices that help prevent forms of what disease? Choices: - pnemonia - bacterial disease - viral disease - cancer A:
cancer
