Answer:
Explanation:
Membrane fusion is the process by which two different cells get united composing a unique membrane that englobes the content con the two original cells. The final new cell is known as heterokaryon. The cellular membrane has the capability to fuse to other membranes without losing their continuity. This is due to its fluidity, provided by the membrane dynamic and complex components.
For membrane fusion to occur it is necessary that they recognize each other. Fusion proteins favor these processes promoting the cell recognition and the local distortion of the cell membrane. Their surfaces get together and form a lipidic structure between the adjacent membranes which continues to form a fusion pore. This pore will expand until the membranes are completely fused. Bilayer structure breaks locally allowing the outer layer to fuse by their hydrophilic heads, a process known as hemifusion. While this happens, the lipidic hydrophobic extremes of the outer layer of one of the membranes get inserted in the other membrane. After that, hydrophilic tails interact with each other and then the polar heads of the inner layer take place to fuse. Both the bilayers are now fused forming a continuous membrane.

A feature known as <u>d. unconformity</u> acts as a cause of gap in geologic record.
<h2>
Explanation:</h2>
An unconformity is the contact between sedimentary rocks that are essentially unique in age or between sedimentary rocks and more seasoned, disintegrated volcanic or transformative rocks. Unconformities act as the cause of the gap in the geologic record.
It occurs for two reasons: silt sediments halted for an impressive time and additionally existing rocks were dissolved before being secured by more youthful residue. It relies upon to what extent disintegration happened or to what extent the deposition stopped.
Actually, large drops of rain form in a cumulonimbus cloud are stated by water vapor condensing in large quantity. If the humidity is very high, or around 100%, water droplets will form extra large during the condensation process. Additionally, this increases the size of the cloud. The droplets will amalgamate to form even larger rain drops that fall because of gravity. I hope this helps! :))
Ps. Cumulonimbus clouds also produce hail, but that hail is not the reason for why they produce big rain drops.

Explanation:
Answer: A vascular bundle is a part of the transport system in vascular plants. A strand of conducting vessels in the stem or leaves of a plant, typically with phloem on the outside and xylem on the inside.
