Answer:
Lycopodium which is an example of Club mosses are seedless vascular plants that are heterosporous.
Explanation:
The club mosses, or phylum Lycopodiophyta, are the earliest group of seedless vascular plants. They can either be homosporous or heterosporous
Some club mosses like Lycopodium clavatum, sporangia are arranged in clusters called strobili.
Lycopodium is heterosporous (while some club mosses are homosporus.
Heterosporus means that spores of two different sizes and sexes are produced by the sporophytes of land plants.
Answer:
See the answer below
Explanation:
<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>
Mathematically,
molarity x number of moles before dilution = molarity x number of moles after dilution.
For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM
Applying the equation:
10 x initial volume = 3 x 2
initial volume = 6/10 = 0.6
<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and 1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>
For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM
10 x initial volume = 8 x 2
initial volume = 16/10 = 1.6
<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
