Question: Answer the following question given this paragraph: Describe at least two major changes to the animal phylogenetic tree that have come about due to molecular or genetic findings. How is it that morphological data alone might lead scientists to group animals into erroneous evolutionary relationships? 26. Briefly describe at least two theories that attempt to explain the cause of the Cambrian explosion. How is it that most, if not all, of the extant animal phyla today evolved during the Cambrian period if so many massive extinction events have taken place since then?. Q: Most, if not all, of the extant animal phyla today evolved during the cambrian period, yet many of what devastating events have taken place since then? A:
OPTIONS:
- life extinctions
- earthquakes
- starvations
- mass extinctions
Answer: mass extinctions

input with options: Answer the following question given this paragraph: Unsaturated fats are found mainly in plant foods, such as vegetable oil, olive oil, and nuts. Unsaturated lipids are also found in fish, such as salmon. Unsaturated lipids are needed in small amounts for good health. Most lipids in your diet should be unsaturated. Q: Most lipids in your diet should be what type, found mainly in plant sources and also in fish? A:
OPTIONS:
- fat
- aromatic
- saturated
- unsaturated
output: unsaturated

Q: Answer the following question given this paragraph: Adulthood does not have a definite starting point. A person may be physically mature by age 16 or 17 but not defined as an adult by law until older ages. In the U. S. , you can't join the armed forces or vote until age 18. You can't buy or use alcohol or take on many legal and financial responsibilities until age 21. Q: What phase of a human life does not have a definite starting point? A:

OPTIONS:
- adolescence
- death
- childhood
- adulthood

A: adulthood

input: OPTIONS:
- photons
- soundwaves
- electrodes
- microwaves Now, answer this question: Answer the following question given this paragraph: Radar stands for ra dio d etection and r anging. In police radar, a radar gun sends out short bursts of microwaves. The microwaves reflect back from oncoming vehicles and are detected by a receiver in the radar gun. The frequency of the reflected waves is used to compute the speed of the vehicles. Radar is also used for tracking storms, detecting air traffic, and other purposes. Q: In police radar, a radar gun sends out short bursts of which waves? A:
A:
output: microwaves

Answer the following question given this paragraph: Hearing losses can occur because of problems in the middle or inner ear. Conductive losses in the middle ear can be partially overcome by sending sound vibrations to the cochlea through the skull. Hearing aids for this purpose usually press against the bone behind the ear, rather than simply amplifying the sound sent into the ear canal as many hearing aids do. Damage to the nerves in the cochlea is not repairable, but amplification can partially compensate. There is a risk that amplification will produce further damage. Another common failure in the cochlea is damage or loss of the cilia but with nerves remaining functional. Cochlear implants that stimulate the nerves directly are now available and widely accepted. Over 100,000 implants are in use, in about equal numbers of adults and children. The cochlear implant was pioneered in Melbourne, Australia, by Graeme Clark in the 1970s for his deaf father. The implant consists of three external components and two internal components. The external components are a microphone for picking up sound and converting it into an electrical signal, a speech processor to select certain frequencies and a transmitter to transfer the signal to the internal components through electromagnetic induction. The internal components consist of a receiver/transmitter secured in the bone beneath the skin, which converts the signals into electric impulses and sends them through an internal cable. Q: Conductive losses in the middle ear can be partially overcome by sending sound vibrations to what structure through the skull, the principle behind implants for hearing loss patients? A:

OPTIONS:
- tympanic membrane
- hammer and anvil
- cornea
- cochlea

Answer: cochlea

Q: Answer the following question given this paragraph: Secondary Succession. Two months after a forest fire, new plants are already sprouting among the charred logs. Q: When did new plants start sprouting after the forest fire? A:

OPTIONS:
- five months later
- two weeks later
- two days later
- two months later

A:
two months later
