B. Lycophyte sporophyte
Explanation:
Lycophytes belong to the division Lycophyta under Pteridophyta. Lycophytes are group of seedless vascular plants.
The living lycophytes are representatives of a plant group that were dominant during the carboniferous period. The extinct groups of lycophytes were mostly tree like tall and large e.g. <em>Lepidodendron</em>
However, the modern day lycophytes are small and herbaceous. They show alternation of generation with the sporophyte being the dominant phase. The leaves are small and simple with an unbranched midrib,these are called microphylls.
The reproduction in lycophytes takes place through spores which are produced inside a sporangia. Specialized leaf like structures called sporophyll bear the sporangia. These sporophylls may or may not be present at the terminal ends of branches and are arranged into definite strobili.
Keeping all these features in mind and comparing the characters of the plant found by the student, we can conclude that the plant is more likely to be a lycophyte sporophyte.
Answer:
The stages of the moon
Explanation:
The term menstruation is related to the moon stages. Because of their coincidence in occurrence and in their duration time, people used to associate the feminine cycle to the moon cycle.
It is commonly said that the ovulation stage coincides with the full moon stage. In the same way, menstruation occurs when there is a new moon.
What really occurs is that the feminine period might or might not coincides with the moon cycle, and depends on each woman. But this is not a strict rule.
The duration of a woman´s cycle depends on every woman, on the raze, on the age, among many other factors. The fact that sometimes the feminine cycle coincides with the moon cycle, does not mean that the moon determines the cycle stages in a woman.
Answer:
either of the two chains that make up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases. a section of one nucleic acid chain that is bonded to another by a sequence of base pairs.
Most bacteria are eventually able to change their genetic makeup in order to become resistant to antibiotics. Therefore, the antibiotics no longer have an effect on the infections.
