Answer the following question given this paragraph: 15.2 Sponges and Cnidarians Animals included in phylum Porifera are parazoans and do not possess true tissues. These organisms show a simple organization. Sponges have multiple cell types that are geared toward executing various metabolic functions. Cnidarians have outer and inner tissue layers sandwiching a noncellular mesoglea. Cnidarians possess a well-formed digestive system and carry out extracellular digestion. The cnidocyte is a specialized cell for delivering toxins to prey and predators. Cnidarians have separate sexes. They have a life cycle that involves morphologically distinct formsmedusoid and polypoidat various stages in their life cycle. Q: Porifera are parazoans that exhibit simple organization and lack true what? Choices: - molecules - nuclei - cell membranes - tissues A:
tissues

Answer the following question given this paragraph: Gluteal Region Muscles That Move the Femur Most muscles that insert on the femur (the thigh bone) and move it, originate on the pelvic girdle. The psoas major and iliacus make up the iliopsoas group. Some of the largest and most powerful muscles in the body are the gluteal muscles or gluteal group. The gluteus maximus is the largest; deep to the gluteus maximus is the gluteus medius, and deep to the gluteus medius is the gluteus minimus, the smallest of the trio (Figure 11.29 and Figure 11.30). Q: Muscles that move what long bone originate on the pelvic girdle? Choices: - patella - tibia - sacrum - femur A:
(Answer)
femur
Ques: Answer the following question given this paragraph: The exact cause of supervolcano eruptions is still debated. However, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion. This creates a caldera into which the surface collapses ( Figure below ). The composition of the eruption is felsic or highly felsic. Q: What kind of eruption do scientists think is caused by a very large magma chamber erupting entirely in one catastrophic explosion? Choices: - brucei eruption - mangxamba eruption - supermagma eruption - supervolcano eruption A:
Ans: supervolcano eruption
(Q).
Answer the following question given this paragraph: The first step in the process of inductive reasoning is making specific observations. In the periodic table of elements, which we will discuss later, there is a group of metals with similar properties called the alkali metals. The alkali metals include elements such as sodium and potassium. If I put sodium or potassium in water, I will observe a very violent reaction every time. I draw a general conclusion from these observations: all alkali metals will react violently with water. Q: Which group of metals in the periodic table include elements such as sodium and potassium? Choices: - igneous metals - actinides - lanthanides - alkali metals A:
(A).
alkali metals
Ques:Answer the following question given this paragraph: Liquid water is taken up by plant roots. The plant releases water vapor into the atmosphere. This is transpiration. Q: What is it called when plant roots absorb liquid water and release water vapor into the atmosphere? Choices: - sedimentation - evaporation - perspiration - transpiration A:

Ans:transpiration
Question: Answer the following question given this paragraph: Recall that terrestrial biomes are defined by their climate. That's because plants and animals are adapted for certain amounts of temperature and moisture. However, would aquatic biomes be classified in the same way? No, that wouldn't make much senseall parts of an aquatic environment have plenty of water. Aquatic biomes can be generally classified based on the amount of salt in the water. Freshwater biomes have less than 1% salt and are typical of ponds and lakes, streams and rivers, and wetlands. Marine biomes have more salt and are characteristic of the oceans, coral reefs, and estuaries. Q: How are aquatic biomes often classified? Choices: - depth - amount of life - amount of light - amount of salt A:
Answer:
amount of salt
