<span>The second atmosphere was formed by outgassing. This means that volcanic eruptions that released CO2, N2O, and H2O aided in forming this atmosphere. The gases, that come from the melting of the Earth's crust, were released into the air after the volcanic activity.</span>
<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.
Answer:
If I can deternine the field-of-view diameter, it makes it easy for me to determine the size of an organism in the field of view.
Explanation:
The advantages of knowing the diameter of the field of view at a given magnification are that I can have a mental picture of the approximate size of how large the specimens are when I can’t certainly determine them with a simple ruler and the metric system. It also enriches me with a good concept of vital ideas of the size of my samples and the size of what’s the organism.
