Which has higher air pressure—warm air or cold air? How do you know?
Masja [62]
The one with higher air pressure is Warm Air.  The reason why is because when you boil water, the water always makes the lid rise.  This is because Warm Air has more activity in its atoms and molecules, so it is moving around more, which in turn means that there is more pressure.  

Hope I helped.  :)

6. Use the results of your observations to explain the roles of muscles, tendons, bones, ligaments, cartilage, and joints in the
kotegsom [21]

Answer:

Explanation:

Muscles are the main form of movement within the wing, extending and contracting the wing, similar to the movement in an arm. Tendons are strands of tough connective tissue that connect the skeletal muscles to bones. Tendons move the wing up and down, allowing for flight and vertical movements. Without tendons, muscles and bones are independent from each other, so by connecting muscles and bones, whenever a muscle contracts or moves, the bone moves as well. Once the bone and muscle have the ability to move together, the body itself can thus be moved in different ways. Muscles also initiate body movements, and, being attached to the bones by the tendons, it controls the movements of the chicken wing by being pushed back and forth. Ligament is the type of connective tissue that connects bones to other bones. The ligaments will allow the bones to move and still keep the bones together in the joint. Cartilages are composed mostly of long, stringy collagen fibers that create bands of tough, fibrous connective tissue. They connect bone to bone at joints and function to reduce friction and protect the ends of the bones when the joint moves. Joints connect the bones together and creates flexibility of the movement being controlled by the muscles and tendons.

wlad13 [49]

Answer:

It is possible to make this categorization as follows:

Roses = Class

Rose samples = instances

Explanation:

In a very direct and objective way, we can state that classes are models that define how a given situation will be handled, which methods will be used to manage it and the objectives that will be established in that situation. Instances, on the other hand, are elements taken from the interior of classes, which contain factors that make them up. Based on this, we can determine that, in the case of the above question, roses are classes and rose samples are instances.
