The diaphragm is the primary muscle used in the process of inspiration, or inhalation
Answer:
prokaryotic cells do not have a nucleus or membrane bound organelles.They also have small rings of double-stranded extra-chromosomal DNA called plasmids.
Answer:
The first two fingers may be stronger due to the fact that they are used the most often and could build up more strength and dexterity. Another reason the first two fingers may be stronger could be due to the fact that the ulnar muscle that controls digits 4 and 5 is smaller than the radial muscle.
Explanation:
Pinch strength is a widely used measurement of hand function. A direct relationship between pinch strength and function has been demonstrated and illustrates the importance of hand strength in clinical practice.There is a difference in grip strength in the dominant and non-dominant hands.Dominant hand is significantly stronger. According to the pinch strength data, he index finger and the thumb are the strongest, the middle finger and the thumb are the second strongest, the ring finger and the thumb are the third strongest, and the little finger and the thumb are last. The difference is the largest between the middle finger and the thumb and the ring finger and the thumb.
The first two fingers may be stronger due to the fact that they are used the most often and could build up more strength and dexterity. Another reason the first two fingers may be stronger could be due to the fact that the ulnar muscle that controls digits 4 and 5 is smaller than the radial muscle.
Difference in the pinch strength may be due to one possible reason that the radial muscle is larger than the ulnar muscle which controls digits 4 and 5. Another reason could be that you generally use the thumb, index, and middle fingers more than the ring and little finger, therefore the first three fingers have more strength and muscle memory.
The classes of chordata which are warm-blooded are birds and mammals.
Explanation:
Warm-blooded animals are those which can maintain their body temperature at a constant.
These classes of chordates balance their internal body temperature with that of the outer environment. When the outer environment is cold, they increase their internal temperature by producing more heat; and when it is hot outside they reduce their internal temperature by cooling themselves.
The food consumed by a warm-blooded animal fuels to maintain a constant body temperature and hence they require more food.
Warm blooded animals cool themselves with the help of sweat glands.
The skin and other parts like fur in birds help to keep the animals warm during winter. Birds also shed their fur in hot season to keep them light. Birds migrate to warm regions during winter.
These animals have high stamina and energy to survive environmental changes. They maintain their temperature through endothermy, homeothermy or tachymetabolism.
Whale living in water is the fish which is also warm blooded because it is a mammal.
