<span>The Zoocholrellae and p. bursaria have a mutual symbiotic relationship. Zoocholrellae are the algae that the p. bursaria live in. The p. bursaria gives Zoocholrellae food while the Zoocholrellae help and allow for the p. bursaria to perform locomotion and move around.</span>
A chemo electrical signal that can travel along cell membranes in a wave-like pattern is called a nerve impulse.
What is a nerve impulse?
- A nerve impulse is an action potential generated across the plasma membrane of the neurons of our nervous system.
- The electrical potential difference generated across the neurilemma i,e., the plasma membrane of the neurons (due to the reception of the external stimulus), is responsible for the generation of the nerve impulse.
- Neurotransmitters, chemicals like acetylcholine, dopamine, etc., are also involved in transmitting nerve impulses across neurons.
Hence, the chemoelectrical signal that can travel along cell membranes in a wave-like pattern is a nerve impulse.

Answer:
Histone
Explanation:
Histones are the proteins that package the DNA in eukaryotes. DNA winds around a core of eight histones creating an structure called nucleosome that determines genome organization. Nucleosomes group and ungroup in an orderly manner allowing gene trasncription or silencing, respectively.
Walking upright.
You can make a case for all of them, but for three of them indirectly.
But the answer, I think, is walking upright.
You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.
Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.
I hope that helps.
