#2. the organ that sensory nerves reach the brain: Sensory neurons assemble to form sensory nerves that reach the brain through the spinal cord. The brain processes the sensory impulses and sends information to the corresponding effector organs through motor nerves
The small finger like projections are: axon terminals, The connection between a neuron and a muscle cell is called a neuromuscular junction. The finger-like projections of the axon are the axon terminals. An action potential moves down to the axon terminals where it causes a chemical message called a neurotransmitter to be released into the synaptic cleft.

Your team is provided with two test materials, C and D. You test the two materials using the air hockey table to collide Object A with Objects C and D. The test material objects are the same size and shape and are very similar in mass. The results are shown in the diagram. The sizes of the arrows are proportional to the acceleration.
Apply Newton’s laws to determine which of these materials is more suitable as a liner for a safety
helmet. Explain your answer.
Answer:
the annswer is b
Explanation:
just look at the questin and then see wicth one you can cross off
The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact. The materials is more suitable as a liner for a safety helmet exists B.
What is meant by Newtons law?The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact. The following is a paraphrasing of these laws: Unless a force acts upon a body, it remains at rest or in continual straight-line motion. First Law of Motion of Newton Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace.
According to the first law, unless a force acts on an object, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction forces upon one another.
The materials is more suitable as a liner for a safety helmet exists B.

On the average, how much energy is lost from each trophic level? explain why
Answer:
I think it's 10% because some of it turns into heat energy
Explanation:
On average, about 90% of the energy is lost from each tropic level. The remaining 10% is available for the next trophic level.
The tropic level of the organisms is the position of organisms occupied in the food web. When an organism consumes other organisms as its food, the energy stored in the form of chemical energy in the organic molecules is converted into the energy used for cellular respiration.
This conversion is not efficient and the energy is lost in the form of heat. Some of the energy is used for growth and maintenance. While other energy is excreted.
Thus, when an organism consumed organic matter, 90% of the energy is lost and 10% of the energy is involved in the building of body tissues. This 10% of energy is passed to the next level.

2. What is the value of the WAVELENGTH for WAVE A?
Answer:
Sorry I really just needed the points ;(
Explanation:
Answer:
1) Amplitude of wave A: 0.5 meters
2) You would have to find the wavelength with the equation λ = [tex]\frac{v}{f}[/tex]
Explanation:
1) Amplitude of a wave is the height of the wave from the horizontal line drawn on "0" to the highest point on the wave.
2) λ is lambda, sign for the wavelength. V is the velocity of the wave, and F is the frequency of the wave.

Firmly hold with one hand the end of a ruler (or similar object) over the edge of a table. Pull the other end down gently and listen to the sound. Then give the ruler (or similar object) a harder downward pull, and see if there is a difference in sound. Describe what you hear and explain the difference using the terms “energy,” “amplitude,” “intensity,” and “decibel.”
2. Take some time to listen to sounds in your environment. Make a list of ten sounds, ranking them from the highest pitch to the lowest. Write a couple of sentences describing whether this was easy or difficult and why. (Some of the sounds can come from tapping objects that vibrate or playing musical notes on an instrument.)
Dominic made the table below to organize his notes about mixtures. A 1-column table. The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? A. The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. B. There is a definite recipe to make each mixture, so the composition of a mixture is set. C. Although it is possible to have more than one state, it is also possible to have only one state. D. A single substance can be used to make a mixture if the substance is composed of more than one element.
Although it is possible to have more than one state, it is also possible to have only one state.Explanation:
