b. neural receptors
c. postsynaptic signals
d. neural impulses
Neurons communicate with each other through synaptic transmission. This involves the presynaptic neuron releasing neurotransmitters into the synapse, which are then received by the postsynaptic neuron to continue the signal. Option A.
Neurons communicate with each other primarily through synaptic transmission. This process is basically the transmission of signals across the synapse (the tiny gap between neurons) through the release of chemicals known as neurotransmitters. One neuron (the presynaptic neuron) releases these neurotransmitters into the synapse, where they can be received by a second neuron (the postsynaptic neuron) via specialized structures known as neural receptors.
These receptors are designed to bind to specific neurotransmitters, resulting in what are known as postsynaptic signals, which then trigger a series of changes that propagate the signal along the neuron. These changes generate a neural impulse (also called an action potential), which is essentially an electrical signal that travels down the neuron's axon and can then trigger the release of more neurotransmitters at the next synapse, continuing the process of communication.

Before forming a hypothesis, an individual firstly makes an observation and formulates a question. Conducting some research follows, which aids in the formation of a hypothesis. A hypothesis, which is an educated guess, predicts the outcome of a situation.
The steps leading up to the formation of a hypothesis typically involve first making an observation about the natural world. This could include noting a trend, pattern or single event. From this observation, questions might arise that the observer seeks to answer. Following observation and question formulation, the next step is often to conduct some research about the topic which can inform the creation of a hypothesis. A hypothesis is a testable statement that predicts the outcome of a situation given certain conditions, often presented in an "If... then..." format. It serves as an educated guess to explain the initial observation.

external would be the answer!
Answer:
The correct answer is "external".
Explanation:
External fertilization is a type of sexual reproduction where the fertilization takes place outside the body of the female organism. This type of reproduction has the advantage that the mother does not need to carry the embryo while it develops. External fertilization is particularly common in aquatic animals, where only sharks and a few types of fish do not reproduce using this adaptation.
Answer: It's uracil!
Explanation: The four nirogen bases in DNA are adenine, guanine, thymine, and cystosine. In RNA, thymine is simply replaced with uracil.
b. False
True
Africa experiences a high level of air pollution because it has more old vehicles on the road than industrialized regions do. This fact is because of the less availabilty of new technologies, due to poverty and other socio-political factors. The environment will likely suffer more too, compromising ever more a region that suffers from different problems.
