Answer:
There is no nuclear membrane in the nucleus of prokaryote
Explanation:
The most important reason why prokaryotes don't have formed nuclei is that the genetic material of prokaryotes has no nuclear membrane, only the relatively concentrated area of genetic material (DNA, etc.), that is, the quasi nuclear area, and there is no obvious boundary between cytoplasm and quasi nuclear; while eukaryotes have nuclear membrane, which makes the nucleus become a relatively independent part of the cell

Answer:
FALSE
Explanation:
Because the magma is less dense than the surrounding rock, it rises toward the surface. Eventually, the magma breaks through the ocean floor, creating volcanoes. ... Hot spots form only under oceanic crust.
In the food chain, a producer absorbs energy from the sun and then uses photosynthesis to turn the sunlight into energy. Then, one of the consumers in the food chain will eat the producer and obtain the producers energy.
Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
A redshift is when light or other electromagnetic radiation from an object moves away from the observer.
