functions such as call set-up, release, and routing, locating cellular devices,
assigning frequencies and transmitting signals to the correct sites. It also provides
useful information such as user registration required to support mobile service
subscribers.
Endoplasmic Reticulum.... i hope im right lol more 90% sure
<h2>Events in Development of Plants</h2>
Explanation:
The events in the development of plants is as follows:
1. Cyanobacteria begin to photosynthesize.
Cyanobacteria which are commonly called as Blue green algae are Prokaryotes.
They are aquatic and photosynthetic, it means, they live in the water, and can manufacture their own food.
2. Cyanobacteria become the chloroplast of plants.
Cyanobacteria have the endosymbiotic plastid. Eukaryotes or plants considered to have evolved from endosymbiotic cyanobacteria.
3. Bryophytes become the first land plants.
Bryophytes are the first land plants to be evolved from aquatic plants, specifically green algae.
4. Plants evolve to have vascular tissue to transport water.
During the evolution of plants from Bryophytes to Pteridophytes, Pteridophytic plants have vascular tissue i.e. xylem and phloem. Xylem helps in transport of water to various parts of the plants.
Embryo should be the answer
Chemical digestion of carbohydrates, proteins, lipids, and nucleic acids. The chemical breakdown of the macromolecules that is contained in food is completed by tons and tons of enzymes that are created in the digestive system!
