The two are potassium and rubidium. Why? Na is an alkali metal. As you go down the metals become more reactive.
Calcium has 20 protons. Why? The atomic # is 20 (the one at the top).
It has 20 neutrons. Why? The atomic mass (the number on the bottom) is ~40, ignoring electron mass. 40- 20 protons = 20 neutrons.
It has 20 electrons.
Why? The # of protons and electrons is the same. Ions aren't on the periodic table.

This can cause other organisms that relay on this specific aquifer to find other sources of water or die.
<span>An aquifer is actually an underground layer of water that contains permeable rocks, gravel, sand etc. the water can be brought to the surface by making a water well. Hydrogeology is the study of aquifers and the way of water flow in the aquifers. The depth of the aquifers differs from area to area and the aquifers that are closest to the surface are used for drinking and irrigation purposes. </span>
Answer:
Explanation:
This is because ferns are vascular plants i.e they have vascular tissues which are xylem and phloems which help to conduct water and nutrients while mosses are non vascular plants.
2. Ferns sporophytes are differentiated into true leaves, stems and true roots while mosses lack true roots, stems and leaves.
Underground stems are modified part of plants that are derived from stem tissues which grow under the ground. Underground stems grow beneath the soil. Examples include Rhizomes, ginger, tubers e t.c.
Roots are to collect water and leafs are to collect sunlight I’m pretty sure and the stem is to take water to the leafs I think
The tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.
<h3>What is the connective tissue?</h3>
Connective tissue is one of the types of primary tissues which has the function of supporting and integrating the rest of the cells since it is the tissue that gives a union of different tissue elements that make up the organs.
This tissue helps move nutrients to the cells they contain in order to give them nutrition, they can also transport other types of substances. Within the types of connective tissue are cartilage, adipose tissue and blood.
Therefore, we can confirm that the tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.
