Answer:
The sporophyte generation is (diploid).
The gametophyte generation is (haploid) .
The embryo is (diploid) .
The megaspore is (polyploid) .
Explanation:
These shows cell division before recombination of gamete.
Your answer would most likely be letter
B. Biosphere
<h2>Membrane potential </h2>
Explanation:
- Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)
- In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential
- Resting membrane potential of excitable cells is established by Na+ and K+pump
- Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels
- Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
- Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
- Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
I believe it goes in the following order top down
1 5 3 4 2.
