Answer:
It's Chloroplast which contains a green pigment responsible for the photosynthesis in plants
The principles of fossil succession and natural selection are connected to Rocks and fossil fuels respectively.
<h3>Define principle of Fossil Succession ?</h3>
A method for determining the relative age of a fossil is through fossil succession. It can put the fossils in chronological order by using the geological strata to identify the rock layers where they are located.
<h3>Principle of fossil selection .</h3>
The law of fossil succession, also referred to as the principle of fossil succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna and that these fossils succeed each other vertically in a definite, reliable order that can be recognized over considerable horizontal distances.

Answer:
The receptors on the postsynaptic membrane (dendrites) of a neuron receive(s) the transmitter released by other neurons.
Explanation:
Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites and an axon. The <u>dendrites </u>are cytoplasmic extensions that <u>receive stimuli from other cells</u>. The axon is a long formation capable of conducting the electrochemical signals.
Every neuron forms connections with other neurons. These connections are known as synapsis. As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area of the other neuron and binds to its <u>receptors in the postsynaptic membrane,</u> located in dendrites of the other neuron. This receptor is a protein structure that triggers an answer. The binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space.
