Answer the following question given this paragraph: The idea of elements is not new. It dates back about 2500 years to ancient Greece. The ancient Greek philosopher Aristotle thought that all matter consists of just four elements. He identified the elements as earth, air, water, and fire. He thought that different kinds of matter contain only these four elements but in different combinations. Q: The ancient greek philosopher aristotle thought that all matter consists of just four what, which he identified as earth, air, water, and fire? Choices: - ingredients - structures - compounds - elements A:
elements
Answer the following question given this paragraph: Q: What is the production of offspring without gamete fusion called? Choices: - ideal reproduction - sexual reproduction - organic reproduction - asexual reproduction A:
asexual reproduction
Q: Answer the following question given this paragraph: Electrons are negatively charged particles in atoms. Moving electrons have a form of kinetic energy called electrical energy . If you've ever experienced an electric outage, then you know how hard it is to get by without electrical energy. Most of the electrical energy we use is produced by power plants and arrives in our homes through wires. Two other sources of electrical energy are pictured in Figure below . Q: Moving electrons have a form of kinetic energy called what? Choices: - potential energy - electromagnetism - deformed energy - electrical energy A:
A: electrical energy
Question: Answer the following question given this paragraph: Assume you are finding the area of a rectangle with a length of 6.8 m and a width of 6.9 m. When you multiply the length by the width on your calculator, the answer you get is 46.92 m 2 . Is this the correct answer? No; the correct answer is 46.9 m 2 . The correct answer must be rounded down so there is just one digit to the right of the decimal point. That's because the answer cannot have more digits to the right of the decimal point than any of the original measurements. Using extra digits implies a greater degree of precision than actually exists. The correct number of digits is called the number of significant figures . To learn more about significant figures and rounding, you can watch the videos at the URLs below. Q: What two measurements are multiplied to find the area of a rectangle? Choices: - depth and width - volume and mass - length and depth - length and width A:
Answer: length and width

Answer the following question given this paragraph: The clavicles are S-shaped bones that position the arms on the body. The clavicles lie horizontally across the front of the thorax (chest) just above the first rib. These bones are fairly fragile and are susceptible to fractures. For example, a fall with the arms outstretched causes the force to be transmitted to the clavicles, which can break if the force is excessive. The clavicle articulates with the sternum and the scapula. The scapulae are flat, triangular bones that are located at the back of the pectoral girdle. They support the muscles crossing the shoulder joint. A ridge, called the spine, runs across the back of the scapula and can easily be felt through the skin (Figure 38.11). The spine of the scapula is a good example of a bony protrusion that facilitates a broad area of attachment for muscles to bone. The Upper Limb The upper limb contains 30 bones in three regions: the arm (shoulder to elbow), the forearm (ulna and radius), and the wrist and hand (Figure 38.12). Q: Which bones are flat and triangular and located at the back of the pectoral girdle? Choices: - vertebrae - laminae - cochlea - scapulae A:
**Answer**
scapulae
Answer the following question given this paragraph: Each endocrine hormone affects only certain cells, called target cells. A target cell has proteins on its surface to which a given hormone can bind. Most endocrine hormones are controlled by negative feedback loops. Negative feedback occurs when low levels of a hormone feed back to increase its secretionand vice versa. Q: Each endocrine hormone affects only certain "target" cells, which have molecules of what on the surface that enable binding of a given hormone? Choices: - lipids - rna - gas - protein A:
protein
