Answer the following question given this paragraph: In other cases, individuals may appear similar although they are not members of the same species. For example, even though bald eagles (Haliaeetus leucocephalus) and African fish eagles (Haliaeetus vocifer) are both birds and eagles, each belongs to a separate species group (Figure 18.10). If humans were to artificially intervene and fertilize the egg of a bald eagle with the sperm of an African fish eagle and a chick did hatch, that offspring, called a hybrid (a cross between two species), would probably be infertileunable to successfully reproduce after it reached maturity. Different species may have different genes that are active in development; therefore, it may not be possible to develop a viable offspring with two different sets of directions. Thus, even though hybridization may take place, the two species still remain separate. Q: If humans were to artificially intervene and fertilize the egg of a bald eagle with the sperm of an african fish eagle and a chick did hatch, that offspring, called a hybrid (a cross between two species), would probably be this? Choices: - fertile - nonviable - mutated - infertile A:
infertile
Answer the following question given this paragraph: An electric circuit consists of one or two closed loops through which current can flow. It has a voltage source and a conductor and may have other devices such as lights and switches. Q: What consists of one or two closed loops through which current can flow? Choices: - thermal reaction - magnetic poles - cooling circuit - electric circuit A:
electric circuit
Q: Answer the following question given this paragraph: Volatile organic compounds (VOCs) are carbon compounds such as methane. VOCs are released in many human activities, such as raising livestock. Livestock wastes produce a lot of methane. Q: The waste of cows releases a lot of which type of gas? Choices: - carbon dioxide - oxygen - sulphur - methane A:
A: methane
Question: Answer the following question given this paragraph: B cells respond to pathogens and other cells from outside the body in the blood and lymph. Most B cells fight infections by making antibodies. An antibody is a large, Y-shaped protein that binds to an antigen , a protein that is recognized as foreign. Antigens are found on the outside of bacteria, viruses and other foreign microorganisms. Each antibody can bind with just one specific type of antigen ( Figure below ). They fit together like a lock and key. Once an antigen and antibody bind together, they signal for a phagocyte to destroy them. Phagocytes are white blood cells that engulf targeted antigens by phagocytosis. As the antigen is on the outside of a pathogen, the pathogen is destroyed by this process. Q: Each antibody can bind with just one specific type of what, resulting in a signal for a phagocyte to destroy them? Choices: - pathogen - adhesion - immunogen - antigen A:
Answer: antigen

Answer the following question given this paragraph: Vascular tissue runs through the ground tissue inside a plant. It transports fluids throughout the plant. Vascular tissue actually consists of two types of tissues, called xylem and phloem. The two types of vascular tissue are packaged together in bundles. You can see them in the celery in Figure below . Q: What are the two types of vascular tissues? Choices: - ectoderm and phloem - epidermis and phloem - ganglia and phloem - xylem and phloem A:
**Answer**
xylem and phloem
Answer the following question given this paragraph: Q: When food is scarce, starving cells secrete a molecule that stimulates neighboring cells to do what? Choices: - compete - hoard energy - die off - aggregate A:
aggregate
