Which two phrases describe a situation that will cause a stationary object to start moving?
A. a net force greater than 0
B. unbalanced forces
C. a net force equal to 0
D. balanced forces
Answer:
A .a net force greater than zero
B. Unbalanced Force
Explanation:
A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .
B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .

Which statement best describes the relationship of photosynthesis and energy?
The process of photosynthesis is energy-storing because the process converts light energy into chemical energy,
which is stored in the bonds of glucose.
The process of photosynthesis is energy-releasing because the process converts light energy into free energy that
can be used for cell functions.
The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming
glucose and oxygen molecules.
The process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that depletes the
cell of energy stored in the bonds of glucose.
Answer: The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming glucose and oxygen molecules.
Explanation: Plants create glucose through sunlight for food, which conserves energy

Answer: D
Explanation: visible light makes up only a very very, very small portion of the entire electromagnetic spectrum
The true statement concerning visible light and electromagnetic radiation is considered to be - d. Visible light is a small portion of the electromagnetic spectrum.
The electromagnetic spectrum is the range of frequencies of electromagnetic waves or radiations. This spectrum also gives an idea about the wavelengths of electromagnetic radiations. The part of the spectrum on their higher to lower energy or frequency range from [tex]10^{4}[/tex] Hz to [tex]10^{18}[/tex] Hz are:

Hint
Answer:
System that receives and transmits information and responses, in addition to work with electrical impulses is the Nervous system.
Explanation:
The nervous system (NS) is responsible for the control of all the organs and functions of the body. The neuron is the functional unit of this system, allowing the transmission of information through nerve impulses, generated by the difference in potential of its cell membrane.
NS is divided into:
Central nervous system (CNS) —where the brain, spinal cord and other structures are located— in charge of receiving, processing and sending information. Peripheral Nervous System (PNS), a network of nerve fibers in charge of receiving the stimuli and conducting the information to and from the CNS.The integration of both NSC and NSP allows an organism to fulfill all its functions, both voluntarily and involuntarily.
