Answer the following question given this paragraph: Plant Parasites Protist parasites of terrestrial plants include agents that destroy food crops. The oomycete Plasmopara viticola parasitizes grape plants, causing a disease called downy mildew (Figure 13.18a). Grape plants infected with P. viticola appear stunted and have discolored withered leaves. The spread of downy mildew caused the near collapse of the French wine industry in the nineteenth century. Q: Which parasite causes downy mildew in grape plants? Choices: - taphrina confusa - epichloe typhina - chrysomyxa ledi - plasmopara viticola A:
plasmopara viticola
Answer the following question given this paragraph: The muscles of the anterior compartment of the thigh flex the thigh and extend the leg. This compartment contains the quadriceps femoris group, which actually comprises four muscles that extend and stabilize the knee. The rectus femoris is on the anterior aspect of the thigh, the vastus lateralis is on the lateral aspect of the thigh, the vastus medialis is on the medial aspect of the thigh, and the vastus intermedius is between the vastus lateralis and vastus medialis and deep to the rectus femoris. The tendon common to all four is the quadriceps tendon (patellar tendon), which inserts into the patella and continues below it as the patellar ligament. The patellar ligament attaches to the tibial tuberosity. In addition to the quadriceps femoris, the sartorius is a band-like muscle that extends from the anterior superior iliac spine to the medial side. Q: Which muscle is a band-like muscle that extends from the anterior superior iliac spine to the medial side? Choices: - vastus medialis - tibialis anterior - soleus - sartorius A:
sartorius
Q: Answer the following question given this paragraph: When the ore leaves the mine, it is not yet a useful material ( Figure below ). Most ores are a combination of metal and other elements. The rocks are full of valuable minerals. They also contain rock that isn't valuable, which is called waste rock. The valuable minerals must be separated from the waste rock. Q: Along with other elements, most ores are made of what? Choices: - coal - crystals - sodium - metal A:
A: metal
Question: Answer the following question given this paragraph: Two factors that affect the pressure of fluids are depth and density. This explains why water pressure is greater deeper in the ocean and air pressure is greatest at sea level. Denser fluids, such as water, exert more pressure than less dense fluids, such as air. Q: What are the two factors that affect the pressure of fluids? Choices: - viscosity and gravity - momentum and density - depth and decrease - depth and density A:
Answer: depth and density
*Question*
Answer the following question given this paragraph: a) The water forms the bottom of the tube and thus where the node of the wave will be. Thus the air column is where the sound wave can exist. The larger the air column, the larger the wavelength. Frequency is inversely proportional to wavelength, thus the tube with the smallest air column will have the highest frequency. So the answer is tube C. Q: In frequency, the larger the air column, the larger the what? Choices: - mass - gravity - absorption - wavelength A:
**Answer**
wavelength
Q: Answer the following question given this paragraph: Inside of elements, you will find identical atoms. An atom is the simplest and smallest particle of matter that still has chemical properties of the element. Atoms are the building block of all of the elements that make up the matter in your body or any other living or non-living thing. Atoms are so small that only the most powerful microscopes can see them. Q: The simplest and smallest particle of matter that still has chemical properties of the element is called? Choices: - a molecule - a nucleus - an isotope - an atom A:
A: an atom
