Answer:
Explanation:
a)
Even if a periodic table is not color coded, we can still find elements with the same chemical properties. This is easy because when we look at the group to find the elements, we see those that have similar chemical properties.
As an example, the Elements of group 1 forms basic oxides. This is a general chemical property of all group 1 elements.
b)
They have similar chemical properties because all the elements in any group has the same number of valence electrons.
c)
Lithium, Sodium and Potassium.
They're all elements of group 1, they all have 1 valence electron

Answer:
Seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds. In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds. The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats. Although seedless vascular plants have evolved to spread to all types of habitats, they still depend on water during fertilization, as the sperm must swim on a layer of moisture to reach the egg. This step in reproduction explains why ferns and their relatives are more abundant in damp environments, including marshes and rainforests. The life cycle of seedless vascular plants is an alternation of generations, where the diploid sporophyte alternates with the haploid gametophyte phase. The diploid sporophyte is the dominant phase of the life cycle, while the gametophyte is an inconspicuous, but still-independent, organism. Throughout plant evolution, there is a clear reversal of roles in the dominant phase of the life cycle
