Answer the following question given this paragraph: muscle cells of the uterus become more sensitive to its effects. Oxytocin is continually released throughout childbirth through a positive feedback mechanism. As noted earlier, oxytocin prompts uterine contractions that push the fetal head toward the cervix. In response, cervical stretching stimulates additional oxytocin to be synthesized by the hypothalamus and released from the pituitary. This increases the intensity and effectiveness of uterine contractions and prompts additional dilation of the cervix. The feedback loop continues until birth. Although the mother's high blood levels of oxytocin begin to decrease immediately following birth, oxytocin continues to play a role in maternal and newborn health. First, oxytocin is necessary for the milk ejection reflex (commonly referred to as "let-down") in breastfeeding women. As the newborn begins suckling, sensory receptors in the nipples transmit signals to the hypothalamus. In response, oxytocin is secreted and released into the bloodstream. Within seconds, cells in the mother's milk ducts contract, ejecting milk into the infant's mouth. Secondly, in both males and females, oxytocin is thought to contribute to parentnewborn bonding, known as attachment. Oxytocin is also thought to be involved in feelings of love and closeness, as well as in the sexual response. Q: What is continually released during childbirth through a positive feedback mechanism and prompts uterine contractions to fetal head toward the cervix? A:
****
A: oxytocin

Answer the following question given this paragraph: Energy also constantly changes back and forth between kinetic and potential energy. Kinetic energy is the energy of movement. For example, a ball falling through the air has kinetic energy because it is moving ( Figure below ). The random motion of molecules is due to kinetic energy, and the driving force behind diffusion. Q: Energy constantly changes back and forth between kinetic and what type of energy? A:
OPTIONS:
- practical
- physical
- mechanical
- potential
potential

Answer the following question given this paragraph: The alchemists were never successful in changing lead into gold. But modern nuclear physics can accomplish this task. Lead is subjected to nuclear bombardment in a particle accelerator. A small amount of gold can be obtained by this process. However, the cost of the procedure is far more than the amount of gold obtained. So the dream of the alchemists has never (and will never) come true. Q: Which procedure helps modern nuclear physics convert lead into gold? A:
OPTIONS:
- nuclear fission
- matter fusion
- evaporation
- nuclear bombardment

Answer: nuclear bombardment

Question: Answer the following question given this paragraph: Bombarding a target of one element with high-energy nuclei or subatomic particles can create new elements. Electrostatic repulsions normally prevent a positively charged particle from colliding and reacting with a positively charged nucleus. If the positively charged particle is moving at a very high speed, however, its kinetic energy may be great enough to overcome the electrostatic repulsions, and it may collide with the target nucleus. Such collisions can result in a nuclear transmutation reaction. Q: What normally prevent a positively charged particle from colliding and reacting with a positively charged nucleus, but may be overcome by kinetic energy?. A:
OPTIONS:
- kinetic repulsions
- toxic repulsion
- evaporation repulsions
- electrostatic repulsions
Answer: electrostatic repulsions

input with options: Answer the following question given this paragraph: The DNA of a chromosome is encoded with genetic instructions for making proteins. These instructions are organized into units called genes . Most genes contain the instructions for a single protein. There may be hundreds or even thousands of genes on a single chromosome. Q: What are the organized instructions within dna for making proteins called? A:
OPTIONS:
- clones
- genomes
- replicants
- genes
output: genes

Problem: OPTIONS:
- mitosis
- pollination
- budding
- sexually
Q: Answer the following question given this paragraph: Most reptiles reproduce sexually, meaning there are two parents involved. In some families of lizards and one snake family, however, asexual reproduction is possible. This is when only one parent is involved in creating new life. For example, the gecko females can make tiny clones of themselves without the aid of a male. Q: What reproductive method has two parents involved? A:
Answer:
sexually
