Well everyone's needs for love and attention are different. It can depend on how you were raised, if you received a lot of attention as a kid, etc. Humans are social creatures so we already crave human interaction. and, going back to how you were raised, even if you were raised quite well and you got enough attention as a kid, it really depends on how people treated you and maybe how many times you've had your heart broken or something along those lines. That need honestly varies from person to person. But I know how it feels, you'll get through it, you'll be okay.
The correct answer is: Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.
Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter ACh binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.
Answer:
C) Underwater organisms in dry land
Explanation:
The listed options are:
A) Large number different-sized footprints.
B) Plant but no animal fossils.
C) Underwater organisms in dry land.
D) Straight teeth buried below curved teeth.
Discovering fossils of underwater organisms in dry land <u>demonstrates that thousands to millions of years ago, there was a body of water such as an ocean, lake, or river in an area that is now dry land.</u> This gives important insights into what was the Earth's climate at that epoch and how it has changed throughout time.
This discovery could allow researchers to study what the conditions were at that time and why that body of water dried out. Moreover, it could lead to answers of the reasons behind the extinctions or evolution of some underwater organisms.
