Answer:
muscles,glands
Explanation:
The part of the body that responds to the stimulus is called an effector organ. The peripheral nervous system is made up of sensory nerves that transmit impulses from the receptors in sensory organs to the central nervous system and motor nerve that transmits impulses from central nervous system to effector. The central nervous system receives and integrates impulses from the receptors and the relays them to the effector organs.
The purpose of an experiment is to compare results with a hypothesis.
The greatest error in the experimental design is that the temperature of both bins were taken at different times from each other. The students should have measured them at the same time to lessen the randomness of the variables. A way to "fix" this is by changing taking into account the extra time between bin A was and bin B was measured for bin B's calculations.
Answer:
Most of the metabolic activities occur in the cytoplasm of the cell.
Cytoplasm is a gel-like fluid present within the cell. It consists of all the contents enclosed within a cell membrane excluding the nucleus.
It is mainly composed of water but also contains salts, enzymes, organelles, and organic molecules.
It is the main site for most of the cellular processes such as glycolysis (first stage of cellular respiration), protein synthesis, mitosis and meiosis etc.
Answer;
-Projection level
-Projection level controls intermediate relay for incoming and outgoing neurons.
Explanation;
The levels of motor control include; segmental level, projection level and precommand level.
-The segmental level is the lowest level of motor hierarchy. It consists of segmental circuits of the spinal cord, Its circuits control locomotion and specific, oft-repeated motor activity. These circuits are called central pattern generators (CPGs).
The projection level consists of: Cortical motor areas that produce the direct (pyramidal) system, and Brain stem motor areas that oversee the indirect (multineuronal) system
. It helps control reflex and fixed-pattern activity and houses command neurons that modify the segmental apparatus.
Precommand level; Cerebellar and basal nuclei systems that:
-Regulates motor activity, precisely start or stop movements, coordinate movements with posture, Block unwanted movements
, and Monitor muscle tone.
