Answer the following question given this paragraph: Amphibians reproduce sexually with either external or internal fertilization. They may attract mates with calls or scents. They do not produce amniotic eggs, so they must reproduce in water. Their larvae go through metamorphosis to change into the adult form. Q: Through what method or methods of fertilization do amphibians sexually reproduce? Choices: - asexual or sexual - mitosis and meiosis - spawning or budding - external or internal A:
external or internal

Answer the following question given this paragraph: As the example implies, gravitational force is completely negligible on a small scale, where the interactions of individual charged particles are important. On a large scale, such as between the Earth and a person, the reverse is true. Most objects are nearly electrically neutral, and so attractive and repulsive Coulomb forces nearly cancel. Gravitational force on a large scale dominates interactions between large objects because it is always attractive, while Coulomb forces tend to cancel. Q: Gravitational force on a large scale dominates interactions between large objects because it is always what? Choices: - ugly - vulnerable - suitable - attractive A:
(Answer)
attractive
Ques: Answer the following question given this paragraph: Long bones are longer than they are wide and have a shaft and two ends. The diaphysis, or central shaft, contains bone marrow in a marrow cavity. The rounded ends, the epiphyses, are covered with articular cartilage and are filled with red bone marrow, which produces blood cells (Figure 38.17). Most of the limb bones are long bonesfor example, the femur, tibia, ulna, and radius. Exceptions to this include the patella and the bones of the wrist and ankle. Q: What is contained in the cavity of a long bone's central shaft? Choices: - blood - calcium - cells - marrow A:
Ans: marrow
(Q).
Answer the following question given this paragraph: The standard cell potential is negative, indicating a nonspontaneous reaction. The battery must be capable of delivering at least 1.10 V of direct current in order for the reaction to occur. Another difference between a voltaic cell and an electrolytic cell is the signs of the electrodes. In a voltaic cell, the anode is negative and the cathode is positive. In an electrolytic cell, the anode is positive because it is connected to the positive terminal of the battery. The cathode is therefore negative. Electrons still flow through the cell form the anode to the cathode. Q: What type of cell has negative anode is positive cathode? Choices: - picric cell - planetoid cell - non-voltaic cell - voltaic cell A:
(A).
voltaic cell
Ques:Answer the following question given this paragraph: Toward the late stages of pregnancy, a drop in progesterone and stretching forces from the fetus lead to increasing uterine irritability and prompt labor. Contractions serve to dilate the cervix and expel the newborn. Delivery of the placenta and associated fetal membranes follows. Q: Toward the late stages of pregnancy, a drop in progesterone and stretching forces from the fetus lead to increasing uterine irritability and prompt labor. contractions serve to dilate the cervix and expel this? Choices: - blood - tissues - uteris - newborn A:

Ans:newborn
Ques: Answer the following question given this paragraph: Sedimentary rocks are laid down horizontally with the oldest at the bottom. Q: What type of rocks are laid down horizontally with the oldest at the bottom? Choices: - crystalline - metamorphic - igneous - sedimentary A:
Ans:
sedimentary
