He used Pea plants to help him find the laws of inheritance. He crossed homozygous (AA) tall plants with short (aa) plants and found that all of the off spring were tall, due to the fact that tall is dominant and short is recessive. He then conducted another experiment where all the offspring mated (all offspring were heterozygous (Aa)) And produced the F1 generation and 25 percent of the plants were short (use a punnet square to see why) and 75 percent were tall.
I hope this response helped :) If u have anymore q about mendelian genetics pls lmk !
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:
B
Explanation:
If it is denser it will more likely sink because of convection currents forcing it down.
Answer:
If we're talking about human organism then
It is multicelular.
It has a backbone.
It contains cells without nuclei.
Explanation:
human as almost all animals in the world is multicellular meaning they have more than one cell (some bacterias has only one)
backbone or "vertebra" is the is the bone of our back who supports us making us stand up.
Yes our cells contain nuclei
, The nucleus contains nucleoplasm, a component where it is immersed in genetic material and as structures that are important for the performance of its functions
And finally our body don't have radial symmetry, radial symmetry is when you can "cut" the image in more than one piece keeping the symmetry in every side, some animals with radial symmetry are the starfish and the jellyfish.
