How does the skeletal and muscular system work in a spider?
In spiders, the skeletal system is their exoskeleton, composed of chitin, which provides support and protection. Their muscles are attached to the inside of the exoskeleton and work in antagonistic pairs to move the spider's limbs by contracting and relaxing. This coordinated effort allows spiders to move, hunt, and perform various functions.
How does your coordination systems work together when you bend your arm?
When you bend your arm, the nervous system sends signals from the brain to the muscles involved in the movement. The muscular system contracts the biceps brachii, which pulls on the forearm, while the triceps relax to allow for smooth movement. The skeletal system provides the structure and leverage needed for the arm to bend at the elbow joint. This coordinated effort enables precise and controlled movement.
What do you need to know to calculate the mechanical advantage of a compound machine?
To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine and the output force obtained from the machine. Additionally, you will need to understand how the individual simple machines within the compound machine are connected or arranged to determine the total mechanical advantage.
Is cutting a copper wire a chemical or physical change?
This is a physical change. Although you could say that the copper atoms are all moving around each other and changing which other atoms they are bonded to, you haven't reacted two substances to produce a different compound, so no chemical reaction. No reaction, ergo not a chemical change.
You put more efforts when you exhale air or when you inhale the air?
During normal breathing at rest, inspiration is an active process while expiration is passive. So under normal conditions, you put more energy into inspiration than expiration.
What is the greatest amount of force a muscle group can exert in a single effort?
muscular strength
It normally requires no muscular effort to exhale?
True is the correct answer
Walking converts what type of energy into mechanical energy?
Walking - or doing any effort with our muscles with that matter - converts chemical energy into mechanical energy. We get the chemical energy from the food we eat.Walking - or doing any effort with our muscles with that matter - converts chemical energy into mechanical energy.

What is the purpose of a compound machine?
less effort, get the jo done quicker
How does the relationship between the skeletal and muscular systems contribute to the movement and support of the human body?
The skeletal system provides structure and support for the muscles to attach to, allowing for movement and stability in the body. The muscles contract and pull on the bones, causing movement at the joints. This coordinated effort between the skeletal and muscular systems enables the body to perform various activities such as walking, running, and lifting objects.
Is any activity that provides goods and services in an effort to earn a profit?
business
The maximal amount of resistance that an individual is able to lift in one single effort is a method of assessing?
The maximal amount of resistance that an individual can lift in one effort is a method of assessing maximal strength. It provides valuable information about an individual's muscle strength and capabilities in a specific movement or exercise. This measure is commonly used in strength training and fitness to gauge progress and set training goals.
What type of pulley can you use to change the direction of the effort force?
Fixed Pulley and Compound Pulley.
What provides historic information on the amount of development and maintenance effort during a product's life?
C
What type of pully can multiply effort force?
Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
What provides historic information on the amount of development and maintenance effort during a product's life cycle?
C
What are Ventilatory assistance devices?
Ventilatory assistance devices are mechanical devices that help a person breathe by replacing some or all of the muscular effort required to inflate the lungs
