The leverage of the biceps brachii applies its force six times closer to the fulcrum (elbow joint) than the resistance. this means it will need to exert <u>36</u> kg of force to support a load of 6 kg.
The triceps brachii (TB) is the only muscle that lies along the posterior humerus. It is a 3-headed, fusiform muscle that, on the shoulder, works in a third-elegance lever since the force is implemented among the joint axis and the weight.
Within the elbow joint, the triceps brachii muscle attaches to the olecranon method of the ulna posterior to the elbow joint. While the triceps contract, it pulls the olecranon procedure proximally, swinging the ulna distally and lengthening the forearm.

Distilled water is an illustration of a lower osmotic pressure than a particular fluid solution, meaning it has less solute in it compared to a red blood cell. The red blood cells would “want” to be in a normal contraction, which would allow water to leave and exit the red blood cell, meaning the red blood cell would stay normal and not shrink or stretch. In a hypotonic atmosphere, water would blast into the red blood cell in an attempt to reach the symmetry, which would cause the red blood cell to lengthen, and perhaps even burst.
The two membranes pull apart a little and create a small pocket or sack of air. As the developing bird grows, it breathes in oxygen from the air sack and exhales carbon dioxide. Several thousand microscopic pores all over the surface of the egg allow the CO2 to escape and fresh air to get in.

A mule is the offspring of a male donkey (a jack) and a female horse (a mare). A horse has 64 chromosomes, and a donkey has 62. The mule ends up with 63. Mules can be either male or female, but, because of the odd number of chromosomes, they can't reproduce.
