Answer the following question given this paragraph: Female monotremes lack a uterus and vagina. Instead, they have a cloaca with one external opening, like the cloaca of reptiles and birds. The opening is used to excrete wastes as well as lay eggs. The eggs of monotremes have a leathery shell, like the eggs of reptiles. Female monotremes have mammary glands but not nipples. They secrete milk to feed their young from a patch on their belly. This form of reproduction is least risky for the mother but most risky for the offspring. Q: Female monotremes share what external opening with reptiles and birds? Choices: - urethra - vagina - anus - cloaca A:
cloaca
Answer the following question given this paragraph: The bacterium in Figure above is a prokaryote. Prokaryotes are microscopic organisms that have neither a membrane-bound nucleus nor membrane-bound organelles. Some cell biologists consider the term "organelle" to describe membrane-bound structures only, whereas other cell biologists define organelles as discrete structures that have a specialized function. Prokaryotes have ribosomes, which are not surrounded by a membrane but do have a specialized function, and could therefore be considered organelles. All metabolic functions carried out by a prokaryote take place in the plasma membrane or the cytosol. Q: All metabolic functions carried out by a prokaryote take place in the plasma membrane or where else? Choices: - extracellular - Shell - mitochondrial - cytosol A:
cytosol
Q: Answer the following question given this paragraph: The vagina is a cylinder-shaped organ that opens to the outside of the body. The other end joins with the uterus. Sperm deposited in the vagina swim up through the cervix, into the uterus, and from there into a fallopian tube. During birth, a baby passes from the uterus through the vagina to leave the body. Q: During birth, a baby passes from the uterus through what organ to leave the body? Choices: - Ovary - the urethra - Esophagus - the vagina A:
A: the vagina
Question: Answer the following question given this paragraph: A mineral deposit that contains enough minerals to be mined for profit is called an ore . Ores are rocks that contain concentrations of valuable minerals. The bauxite shown in the Figure below is a rock that contains minerals that are used to make aluminum. Q: What type of rock contains concentrations of valuable minerals? Choices: - sedimentary - igneous - metamorphic - ores A:
Answer: ores

Answer the following question given this paragraph: Most crustaceans have separate sexes, so they reproduce sexually using eggs and sperm. Many land crustaceans, such as the Christmas Island red crab, mate every season and return to the sea to release the eggs. Others, such as woodlice, lay their eggs on land when the environment is damp. In some crustaceans, the females keep the eggs until they hatch into free-swimming larvae. Q: Most crustaceans have separate sexes, so they reproduce sexually using what? Choices: - pod and eggs - eggs and pod - asexual reproduction - eggs and sperm A:
**Answer**
eggs and sperm
