Explanation: The answer is D. An observation that has a number associated with it. I would explain further, but it is pretty self explanatory.
<em>Good luck!</em>
Answer:
The answer should be "by an increase in the weathering of rocks that contribute to the mineral makeup of soil"
Explanation:
The rate of soil formation can be accelerated by an increase in the weathering of rocks that contribute to the mineral makeup of soil. Topsoil can be increased through the increase of available organic material. Erosion can also lead to an increase in available parent material for soil formation.
I hope the helps :)
sorry if it's wrong.
Answer:The correct order is:
Ion channels - synaptic vesicle - neurotransmitter - end plate potential.
Explanation: A neuromuscular junction is the point where a motor neuron meets with a skeletal muscle fiber which it innervates.
It is the site where a chemical interaction or communication between a motor neuron and a muscle cell occurs. For transmission of impulses to occur between a neuron and a muscle cell, an action potential from the motor neuron travels along the axon of the neuron to the presynaptic terminal of the neuron where it activates voltage gated calcium ion channels which causes the influx of calcium ions into the intracellular space of the neuron. The calcium ions bind to the sensor proteins that are located on the synaptic vesicles and trigger the release of the neurotransmitter into the synaptic cleft. The neurotransmitter moves from the synaptic cleft and binds to its receptors on the postsynaptic membrane of the muscle cell. The binding of the neurotransmitter to its receptors creates end plate potential which causes the skeletal muscle fibers to depolarise.
Answer:
Explanation:
Myth: Is a bigger penis better?
Truth: Penises come in all shapes and sizes. The idea that bigger is better is simply false. What really makes sex better is compatibility with your partner and open communication about what feels good and what doesn’t.
Myth: Vaginas are tight or loose depending on the amount of sex a person has had.
Truth: The “tight vs. loose” idea is fairly common, but it is purely false. The vagina is a muscle that expands and contracts. When a person is aroused, the walls of the vagina soften and lengthen, making insertion easier. If they are nervous, the walls of the vagina will naturally contract, making insertion difficult.
Myth: Sex is painful.
Truth: Sex should feel good –even if you are having sex for the first time or if you have had sex before . Feeling safe and comfortable is what’s important. If someone is nervous or tense, their muscles will contract, which may cause discomfort. If something does not feel good, tell your partner. You may need to slow down, use a lubricant or stop until you are feeling ready and comfortable.
Myth: Everyone is having sex.
Truth: It may seem like everyone is having more sex than you. The fact is everyone has different sex drives. Some people want to have sex a lot, while others are not interested in sex at all. What’s important is you are true to yourself and not worrying about what other people are doing.
