Answer:
Skin,muscles and metabolism play a significant role in maintaining his body temperature
Explanation:
Role of skin
In cold environment the blood vessels of the skin constrict to prevent the loss or liberation of heat from his(jim) body.
Role of muscles
The one of principle function of muscle is to store glycogen.The stored glycogen of jim"s muscle undergo glycogenolysis to generate heat inside his body.
Role of metabolism
In cold environment the rate of aerobic respiration and other catabolic reactions such as beta oxidation of fatty acid occur to generate energy in form of heat in his body.
<span>The answer is the option D. It is false that most scientist do not use the metric system or SI. SI, the international system was adopted many years ago. It was an evolution of the metric system. In 1960 a commite of international scientists adopted it. Since then, the SI has spread widely and it is a must for the scientist to use it. </span>
Murmurs can be faint to very loud and sometimes make a whooshing or swishing noise. There are categories of murmur these are the harmless and the abnormal. Children with murmur don't need a special diet, or any restriction of activities they just need to be understood and make them feel they are not different from the others.
Bloodstain shape is determined by the angle between the flight path of the droplet and the surface that it impacts (Fig.1). When a drop of blood strikes a horizontal surface from the perpendicular (at an angle of 90°, Fig.2), the resulting bloodstain will be round. As the angle between the blood drops’ flight path and the target surface decreases, the length of the resulting bloodstain increases and the width decreases; in other words, the bloodstain becomes longer and narrower as the size of the angle decreases (Fig.3). A blood drop that has impacted a target surface from an angle of 12° will be long and narrow (Fig.4). Also present on these long, narrow stains is a ‘tail’ (Fig. 4). As the drop of blood impacts the target surface, the main body of the droplet will stick to the surface. A small portion of the blood drop will tear off from the top and continue in a forward direction. This secondary spatter has the appearance of a tail.
