The pulmonary circuit transports blood to the lungs. The blood is oxygenated there and then carried back to the heart. Gaseous exchange happens in the lungs:

Carbon dioxide diffuses from the blood into the air in the alveoli.

Name the receptors that respond to a stimulus within the body but their location is restricted to skeletal muscles, tendons, joi
suter [353]

Answer:

proprioceptor

Explanation:

Proprioceptors are the receptor located in a joint, muscle, or tendon. These receptors are concerned with locomotion, posture, and muscle tone. These receptors respond to internal stimuli only and are present in a specific location in the body. For example, the tendon organ is a proprioceptor present in the tendon. The function of the tendon organ is to monitor the muscle tension and to prevent its tearing. These receptors also help smooth start and termination of muscle contraction.

Proprioceptors are the mechanoreceptors that regulate the body’s equilibrium and posture by their role in reflex actions that maintain muscle tone. They sense the position of limbs by detecting the degree of muscle relaxation, the stretch of tendons, and ligament movements.

Describe the Watson and Crick model of DNA structure. How did it fit the data provided by Chargaff and the X-ray diffraction pat
icang [17]

DNA model given by Watson and Creek in the year of 1953 gave a very detailed study regarding the structure of B DNA which is valid till date and is essentially corroborating with Chargaff's data and Xray diffraction pattern.

<h3><u>Explanation:</u></h3>

The DNA is the most common nucleic acid found in the living organisms as a genetic material. As stated by Watson and Creek, this DNA contains a double helical structure with two sugar phosphate backbones and the nitrogen bases getting projected from it inwards. The backbones are formed of ribose sugar and phosphate and joined together with a phosphodiester bond. The ribose sugar is attached to phosphates at its 3' and 5' Carbon atoms. The nitrogen bases found in DNA are Adenine, Guanine, Thymine and Cytosine. The Adenine has two hydrogen bonds with thymine and guanine has 3 hydrogen bonds with cytosine.

Each full turn of a helix is 34A and each base pair is 3.4A apart. The distance between two strands of DNA is 20A.

Chargaff's rule regarding the equal amount of adenine and thymine as well as guanine and cytosine is matching with this structure. All the other rules also do match with this DNA structure.

You are working in an emergency care center. a person comes in dehydrated and the doctor orders a hypertonic solution. explain w
andrezito [222]
Dehydration is the loss of too much water in our body  It can be categorized into three types: isotonic, hypotonic and hypertonic. Isotonic dehydration is the most common, which pertains to equal concentrations of the extracellular and intracellular fluids. In this type of dehydration, about same amount of electrolytes and water are ;pst from the body. Hypertonic dehydration is more serious and a very risky IV fluid to administer. This type of dehydration occurs when more electrolytes are lost than water from the body. So, there must be an intake of a fluid more concentrated in electrolytes so that it will cause the water from inside the cells to be attracted to the extracellular fluid. The last type of dehydration, hypotonic dehydration, is the opposite of hypertonic. This is when more of water is lost than electrolytes. So, the fluid to be administered is less concentrated relative to the fluid inside the cells.
