I will go with choice (C) density dependent pattern
DNA replication only happens during meiosis because the chromosome number of the species remains the same from one generation to the next, the chromosome number of germ cells must be reduced by half during meiosis. To achieve this feat, meiosis, unlike mitosis involves a single round of DNA replication followed by two rounds of cell division.

Answer:
The correct sequence is 21543.
Explanation:
The procedure by which the signaling molecules known as neurotransmitters are discharged by the neuron's axon terminal and combines and reacts with the receptors present on the dendrites of another neuron or postsynaptic neuron is termed as neurotransmission.
The following are the steps followed in the process of neurotransmission:
a. Exocytosis of neurotransmitter gets stimulated by calcium.
b. The diffusion of neurotransmitter takes place across the synaptic cleft.
c. The binding of neurotransmitters takes place with the receptor.
d. After the binding opening of ion channels takes place.
e. The permeability of the postsynaptic membrane gets changed.
Answer:
Eukaryotes
Explanation:
Eukaryotic cells have membrane bound organelles.
Prokaryotic cells do NOT have membrane bound organelles.
So, a Eukaryotic cell has structures such as a nucleus, mitochondria, a golgi complex, etc. This provides the cells with distinct stuctures that have distinct functions.
consider the expression of a protein (protein synthesis.) Transcription of the DNA into RNA happens within the nucleus. The mRNA is sent from the nucleus to the cyctoplasm, where translation occurs at either the rough endoplasmic reticulum or the free floating ribosomes.
A prokaryotic cell has all of its machinery floating around inside its cytoplasm with no separation. In these cells, transcription and translation both occur in the cytoplasm. In fact, translation often begins before transcription is finished...
