Answer:
The Particles that make up the aluminum bar are moving slowly.
Explanation:
Hope this helps.
Living organisms needs water to survive. fresh water also carries fresh nutrients.
Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.
An action potential is an electrical signal that travels along the cell membrane as a wave.
This action potential (muscle action potential) drives the contraction of muscle fibers.
When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.
Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.

Answer:
Suppose:
a given gene undergoes a mutation to its dominant allele such that two out of 100,000 offspring exhibit the new mutant phenotype.
Assuming that these two offspring are heterozygous,
Mutation rate for the gene = 1/100,000
Answer: A) Ocean water evaporates and the warm, moist air rises higher into the atmosphere.
Explanation:
The Equator receives the most direct sunlight on Earth. This makes the water near the Equator, and air above the water, typically warmer than surrounding areas. This warm, moist, less-dense air rises, and then cools as it travels through denser, colder layers. This constant cycle of evaporation and condensation creates an abundance of rain.
So, oceans near the Equator provide ideal conditions for rainfall because ocean water evaporates and the warm, moist air rises higher into the atmosphere.
