It is a fern and belongs to Phylum Pterophyta
Fern is a plant with fronds that are attached to rhizomes. The frond is the leaf of the fern and the rhizome is the root which grows. They have vascular tissue which means that they use tubular structures to transport nutrients throughout the plant. They reproduce by spores and have neither seeds nor flowers.

Answer - <span>Fertilization would result in a zygote with twice as many chromosomes as the parents.
Reasoning - Without Proper stable form of stages it would double and the cells wont be able to survive in the next generation.</span>
Answer:
d
Explanation:
When considering the frequency of the potential alleles of a gene in a population, the total must add up to 1. Think of it like percentages. an allele frequency of 0.3 means 30% of the population carry it (out of a possible 100%).
We know that the frequency of c1 is 0.3. Lets take each option and see if it can be true
a) cannot be less than 0.3. - false. It <em>could </em>be less than 0.3. For example, it could be 0.1, meaning the frequency of allele c3 would be 0.6 (because 0.3 + 0.1 + 0.6 = 1)
b) cannot be greater than 0.3. - false. It <em>could </em>be greater than 0.3. For example, it could be 0.5, meaning the frequency of allele c3 would have to be 0.2 (because 0.3 + 0.5 + 0.2 = 1)
c) is 0.7. - false. It <em>can't </em>be 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)
d) cannot be greater than 0.7. - true. It <em>cannot </em>be greater than 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)
