<span>Angiosperms are flowering plants.It is the most diverse group of plants with more than 250,000 species. They are called angipsperms because their seeds are enclosed in a carpel (in a vessel).
Angiosperms are the most diverse and successful plant group today because the reproduction is aided by flowers, protected seeds and insect pollinators (A). The flower lures insects, birds, bats to itself, and in the process has dramatically increased the diversity of flowering plants.Closed carpel allow seed protection.</span><span />
Research has demonstrated that neural stem cells have an impaired ability to differentiate into functional neurons when subjected to ethanol. They found out that treating cultured neural system impairs their ability to differentiate in functioning neurons. With this impairment it seems to be united with aberrant, dense methylation and loci which are active in normal tissue.
The following statements apply to autotrophs only:
1. Make their own food.
2. Use inorganic materials to produce energy.
3. Producers.
4. Many use photosynthesis to produce organic compounds.
The following statements apply to heterotrophs only:
1. Consumers.
2.Rely on other organisms for energy.
3. Unable to produce organic compounds from inorganic materials.
4. Obtain their food by consuming other organisms.
Generally, autotrophs are plants, which are capable of trapping the energy of the sun to produce their own food. That is why they are called producers. They have the capacity to produce organic compounds using inorganic raw materials. Other living organisms depend on the foods produced by autotrophs. The heterotrophs do not have the capacity to produce their own foods so they depend on the food produce by autotrophs, they also feed on other living organisms. That is why they are called consumers. <span />
This is called replication. You replicate the exact DNA molecule into two identical molecules.
