The diagram shows an experiment conducted to measure how quickly water moves through different sized particles. Small particles of marble and large particles of granite are put into two identical glass cylinders. Each cylinder contained equal volumes of
different sized particles. One cup of water was added to the top of each column. A student timed how long it took for the water to begin collecting in the pans under each
wire screen. The student recorded the data in a table.
Which variable was not held constant in the experiment?
A amount of water
B volume of the particles
C identical columns
D particle substance
Answers
Answer:
D
Explanation:
A) it is mentioned that 1 cup of water was added to each column which shows that the amount of water added to eahc column was constant, or the same
B) it is mentioned that the cylinder contained equal volumes of different sized particles, which means volume fo particles is constant as there are equal volumes
C) It is also reasonable to assume that the columns are identical as its not mentioned that they weren't, thus makking this variable constant
D) It is mentioned that small particles of marble and large particles of granite were used, this is the independent variable or the variable we change to look at the different reactions, since there re 2 different substances(marble and granite) being used the type of substance is NOT constant

Answers
Answer:
A Cappella
Explanation:
A cappella.
This is a very entertaining trivia question of the day and the correct solution is as follows: What Italian musical term translates to in the church style? A cappella.
A cappella music is a performance by a singer or a singing group without instrumental accompaniment, or a piece intended to be performed in this way. The term a cappella was originally intended to differentiate between Renaissance polyphony and Baroque concertato musical styles. In the 19th century, a renewed interest in Renaissance polyphony, coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists, led to the term coming to mean unaccompanied vocal music. The term is also used, rarely, as a synonym for alla breve.

Termination of the nerve impulse at an nmj results in the passive sliding of ______ back to their original state.
Answers
Termination of the nerve impulse at NMJ results in the passive sliding of Myofilaments back to their original state. The sliding filament theory got its name from the way these filaments slide in and out of one another to create a muscular contraction.
What shortens the sliding filament theory?The sliding filament theory states that myosin filaments shrink sarcomeres within a muscle fiber by pulling actin filaments closer together. A muscle fiber contracts when every sarcomere in the fiber shortens.
When the signal from the nervous system is no longer present, muscle fibers relax. The chemical reaction that causes the rearranging of the proteins in the muscle fibers is interrupted when the stimulation of the motor neuron giving the impulse to the muscle fibers ceases.
