Answer the following question given this paragraph: The volume of a gas contains only about 10% matter, with the rest being empty space. Hsub is equal to Hvap. Q: The volume of a gas is comprised of about 10% matter. what is the rest? Choices: - open space - instead space - normal space - empty space A:
empty space
Answer the following question given this paragraph: The solution is basic and so its pH is greater than 7. The reported pH is rounded to two decimal places because the original mass and volume has two significant figures. Q: What level is greater than 7 in a basic solution? Choices: - fh - gh - uh - ph A:
ph
Q: Answer the following question given this paragraph: As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell's needs. This idea is explained in Figure below . However, large cells have a way of dealing with some size challenges. Big cells, such as some white blood cells, often grow more nuclei so that they can supply enough proteins and RNA for the cell's requirements. Large, metabolically active cells often have lots of cell protrusions, resulting in many folds throughout the membrane. These folds increase the surface area available for transport of materials into or out of the cell. Such cell types are found lining your small intestine, where they absorb nutrients from your food through protrusions called microvilli . Q: As a cell grows, its volume increases more quickly than its what? Choices: - density - age - weight - surface area A:
A: surface area
Question: Answer the following question given this paragraph: Ecosystems require constant inputs of energy from sunlight or chemicals. Producers use energy and inorganic molecules to make food. Consumers take in food by eating producers or other living things. Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment. Q: What do decomposers release once they have broken down the dead organisms? Choices: - essential molecules - unusable molecules - organic molecules - inorganic molecules A:
Answer: inorganic molecules

Answer the following question given this paragraph: Testes The testes (singular = testis) are the male gonadsthat is, the male reproductive organs. They produce both sperm and androgens, such as testosterone, and are active throughout the reproductive lifespan of the male. Paired ovals, the testes are each approximately 4 to 5 cm in length and are housed within the scrotum (see Figure 27.3). They are surrounded by two distinct layers of protective connective tissue (Figure 27.4). The outer tunica vaginalis is a serous membrane that has both a parietal and a thin visceral layer. Beneath the tunica vaginalis is the tunica albuginea, a tough, white, dense connective tissue layer covering the testis itself. Not only does the tunica albuginea cover the outside of the testis, it also invaginates to form septa that divide the testis into 300 to 400 structures called lobules. Within the lobules, sperm develop in structures called seminiferous tubules. During the seventh month of the developmental period of a male fetus, each testis moves through the abdominal musculature to descend into the scrotal cavity. This is called the "descent of the testis. " Cryptorchidism is the clinical term used when one or both of the testes fail to descend into the scrotum prior to birth. Q: What is the name for the male reproductive organs or gonads? Choices: - nucleus - anus - ovaries - testes A:
**Answer**
testes
Answer the following question given this paragraph: Neutron stars are the corpses of stars left over after supernova explosions. They are the size of a small city, but can spin several times per second. (Try to imagine this in your head. ) Consider a neutron star of radius 10 km that spins with a period of 0.8 seconds. Imagine a person is standing at the equator of this neutron star. Calculate the centripetal acceleration of this person and compare it to the acceleration due to gravity on Earth. Q: Neutron stars are the corpses of left over what? Choices: - planet explosions - gravitational explosions - stellar explosions - supernova explosions A:
supernova explosions
