Q: Answer the following question given this paragraph: When the ventricles begin to contract, pressure within the ventricles rises and blood flows toward the area of lowest pressure, which is initially in the atria. This backflow causes the cusps of the tricuspid and mitral (bicuspid) valves to close. These valves are tied down to the papillary muscles by chordae tendineae. During the relaxation phase of the cardiac cycle, the papillary muscles are also relaxed and the tension on the chordae tendineae is slight (see Figure 19.13b). However, as the myocardium of the ventricle contracts, so do the papillary muscles. This creates tension on the chordae tendineae (see Figure 19.14b), helping to hold the cusps of the atrioventricular valves in place and preventing them from being blown back into the atria. The aortic and pulmonary semilunar valves lack the chordae tendineae and papillary muscles associated with the atrioventricular valves. Instead, they consist of pocket-like folds of endocardium reinforced with additional connective tissue. When the ventricles relax and the change in pressure forces the blood toward the ventricles, the blood presses against these cusps and seals the openings. Q: When the ventricles begin to contract, pressure within the ventricles rises and blood flows toward the area of lowest pressure, which is initially in the atria. this backflow causes the cusps of the tricuspid and mitral (bicuspid) valves to close. these valves are tied down to the papillary muscles by these? A:

- chollphyide tendineae
- choanocyte tendineae
- photoreactive tendineae
- chordae tendineae

A: chordae tendineae

input: OPTIONS:
- organs
- five senses
- glial cells
- limbs and joints Now, answer this question: Answer the following question given this paragraph: 36.2 Somatosensation Somatosensation includes all sensation received from the skin and mucous membranes, as well as from the limbs and joints. Somatosensation occurs all over the exterior of the body and at some interior locations as well, and a variety of receptor types, embedded in the skin and mucous membranes, play a role. There are several types of specialized sensory receptors. Rapidly adapting free nerve endings detect nociception, hot and cold, and light touch. Slowly adapting, encapsulated Merkel's disks are found in fingertips and lips, and respond to light touch. Meissner's corpuscles, found in glabrous skin, are rapidly adapting, encapsulated receptors that detect touch, lowfrequency vibration, and flutter. Ruffini endings are slowly adapting, encapsulated receptors that detect skin stretch, joint activity, and warmth. Hair receptors are rapidly adapting nerve endings wrapped around the base of hair follicles that. Q: Somatosensation includes all sensation received from the skin and mucous membranes, as well as from these? A:
A:
output: limbs and joints

Answer the following question given this paragraph: The most common type of brain injury is a concussion. This is a bruise on the surface of the brain. It may cause temporary symptoms such as headache and confusion. Most concussions heal on their own in a few days or weeks. However, repeated concussions can lead to permanent changes in the brain. More serious brain injuries also often cause permanent brain damage. Q: What is the most common type of brain injury? A:

OPTIONS:
- Diffuse Axonal
- Anoxic Event
- Contusion
- concussion

Answer: concussion

Problem: OPTIONS:
- leaves
- cilia
- stem
- roots
Q: Answer the following question given this paragraph: Q: Which part of the plant conduct water and minerals as well as anchor the plant. A:
Answer: roots

Problem:OPTIONS:
- Carl Sagan
- Albert Einstein
- Niels Bohr
- nikola tesla

Answer the following question given this paragraph: For static electric charges, the electromagnetic force is manifested by the Coulomb electric force alone. If charges are moving, an additional force emerges, called magnetism. The century realization that electricity and magnetism are dual aspects of the same force completely changed our understanding of the world we live in. Insights due to Ampere, Gauss, and Maxwell led to the understanding that moving charges electric currents create magnetic fields. Varying magnetic fields create electric fields. Thus a loop of wire in a changing magnetic field will have current induced in it. This is called electromagnetic induction. Magnetic fields are usually denoted by the letter and are measured in Teslas, in honor of the Serbian physicist Nikola Tesla. Q: The measure of magnetic fields is named after a serbian physicist. what is his name? A:
****
A: nikola tesla

Problem:OPTIONS:
- Paleolithic era
- Mesozoic epocH
- Jurassic period
- quaternary period

Answer the following question given this paragraph: The Quaternary Period is the time since the beginning of the ice ages. The climate has been cooler than it was earlier in the Cenozoic. Since the end of the Pleistocene ice ages, which are probably not entirely over, we have been in the Holocene Epoch. The Holocene is also called the Recent. Q: What is the time since the beginning of the ice ages? A:
****
A:
quaternary period
