How do animals with no circulatory system get their material needed?
By simple diffusion
Why is sunlight needed in maintaining ecosystem?
It provides the energy to run it.
How do plants obtain gases needed for respiration and photosynthesis?
partially by diffusion, but most leaves have pores that facilitate the diffusion.
What is essential for diffusion?
A- A Concentration Gradient B- A Selectively Permeable Membrane C- A Source of Energy D- A Protein The Answer Is (A) Diffusion can occur without a semipermeable membrane, as diffusion is simply movement of a substance from high to low concentration. A source of energy is needed only for active transport. Proteins are needed if the the particles transported are too big to pass the semipermeable membrane.
Energy that drives diffusion?
Diffusion occurs via random atomic [and molecular] collisions. The Kinetic Energy that is needed to accomplish this is derived exclusively from Heat. No Heat, or even Warmth, yields no Diffusion.
Cell energy is needed in?
diffusion
How do animals with no circulatory system get their material needed?
By simple diffusion
What is the rate at which an object is moving at a given instant called?
speed if no direction is needed velocity if direction is needed
What is needed to to facilitate diffusion and active transport?
ATP is needed for these two transport mechanisms to occur.
Is water needed for maintaining the firmness of a plant's stern?
yes
Why is sunlight needed in maintaining ecosystem?
It provides the energy to run it.
What is needed to change the direction of a moving mass?
The answer is force because Force is needed to change the direction of a moving mass.
This is an odd question but does glucose have any other roles or jobs in the universe other than a food or fuel for metabolism?
Glucose is important for many functions in the body beside for food metabolism. It is used in respiration, determining disease factors in many blood tests, helps the diffusion of cells, maintaining homeostasis, important in molecular structure of the body, for oxygen use and distribution throughout the body, and is expelled through urine when not needed.
Why adequate rest is needed for maintaining good health?
to relax the brain
When a simple machine is used to perform a task what factors may be affected?
the amount of force needed to perform the task the distance over which the force is applied the direction in which the force is applied
When a simple machine is used to perform a task factors may be affected?
the amount of force needed to perform the task the distance over which the force is applied the direction in which the force is applied
What must be included when reporting an objects velocity-?
Speed and direction of motion are needed to determine velocity.
