<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
Some charophytes are group of organisms should feature cell division most similar to that of land plants.
<h3>What is evolution?</h3>
Evolution is a process of change in a population through genetic variation over time. Evolution involves change over time and descents from common ancestor.
Types:
- Convergent evolution
- Divergent evolution

Answer:
DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.
Explanation:
DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.
