how an adaptation in angiosperms to provide nutrition for its embryos has become such a major food source for humans

Let's see, the nutrition storage for the embryo would be:
the endosperm in seeds 
the cotyledon(s) in seeds may also be modified for storage (and may absorb the endosperm in doing so!) 

So: we eat seeds, which includes eating the cotyledon(s) and the endosperm. Our major food sources these days that are seeds include our grain crops, the seeds of legume crop plants (e.g. beans, peas), and "nuts."

How can bacteriophage dna be spread from cell to cell without causing cell death?

nexus9112 [7]

Answer:

through lysogenic cycle

Explanation:

The bacteriophage attaches itself on the bacterial surface. The DNA strand to be replicated is injected into the bacteria by the bacteriophage. The DNA integrates into the bacterial chromosome and becomes a pro-phage.

The bacterial cell proceeds to cell division through budding. The progeny possess the bacteriophage. After complete replication, the virus DNA detaches from the host genome and enters the lytic cycle. The capsid heads assemble on the surface of bacterial cell to package the fully matured viral DNA . The phage produces lytic enzymes that weaken the cell wall of bacteria cell.

Answer:

Are you referring to symbiotic relationships between organism? If so, the answer would be parasitism.

One organism, a parasite, takes advantage of another organism at the expense of the host organism.

Ex. A tick bites a dog for blood to use as food. The dog gets an uncomfortable bug bite and the dog might catch a tick borne disease.
