Q: Answer the following question given this paragraph: Q: In animal cells, what arises from the centrosomes and includes spindle microtubules and asters? A:

OPTIONS:
- Golgi apparatus
- ribosomes
- DNA helix
- the spindle

A: the spindle

input: OPTIONS:
- heat
- earth
- food
- sun Now, answer this question: Answer the following question given this paragraph: Figure 4.2 Ultimately, most life forms get their energy from the sun. Plants use photosynthesis to capture sunlight, and herbivores eat the plants to obtain energy. Carnivores eat the herbivores, and eventual decomposition of plant and animal material contributes to the nutrient pool. Q: Ultimately, most life forms get their energy from this? A:
A:
output: sun

Answer the following question given this paragraph: 12.5 The Onset of Turbulence Sometimes we can predict if flow will be laminar or turbulent. We know that flow in a very smooth tube or around a smooth, streamlined object will be laminar at low velocity. We also know that at high velocity, even flow in a smooth tube or around a smooth object will experience turbulence. In between, it is more difficult to predict. In fact, at intermediate velocities, flow may oscillate back and forth indefinitely between laminar and turbulent. An occlusion, or narrowing, of an artery, such as shown in Figure 12.17, is likely to cause turbulence because of the irregularity of the blockage, as well as the complexity of blood as a fluid. Turbulence in the circulatory system is noisy and can sometimes be detected with a stethoscope, such as when measuring diastolic pressure in the upper arm's partially collapsed brachial artery. These turbulent sounds, at the onset of blood flow when the cuff pressure becomes sufficiently small, are called Korotkoff sounds. Aneurysms, or ballooning of arteries, create significant turbulence and can sometimes be detected with a stethoscope. Heart murmurs, consistent with their name, are sounds produced by turbulent flow around damaged and insufficiently closed heart valves. Ultrasound can also be used to detect turbulence as a medical indicator in a process analogous to Doppler-shift radar used to detect storms. Q: Turbulent sounds, at the onset of blood flow when the cuff pressure becomes sufficiently small are called? A:

OPTIONS:
- pinworm sounds
- whooping sounds
- choanocyte sounds
- korotkoff sounds

Answer: korotkoff sounds

Problem: OPTIONS:
- they are not oxidised
- they are transcribed
- they are exterminated
- they are not transcribed
Q: Answer the following question given this paragraph: Structure of the trp operon. The trp operon is composed of 5 structural genes, 1 regulatory gene and other regulatory sequences, including the promoter, operator and leader sequence. Within the leader sequence is the attenuator region. In the presence of tryptophan, the structural genes are not transcribed. Q: What happens to structural genes in the presence of tryptophan? A:
Answer: they are not transcribed

Problem:OPTIONS:
- solar energy
- mechanical energy
- thermal energy
- potential energy

Answer the following question given this paragraph: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity. Q: What kind of energy comes from the position of a charged particle in an electric field? A:
****
A: potential energy
