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
Explanation:
They are called even-aged
hope this helped :)
The answers is the symptoms can change with age
Hope help!
Blue eyes are a recessive trait meaning Pats parents would both be heterozygous with one dominant gene and one recessive for each parent.
Hm, raw materials: three stages exist in the electron transport: It is, glycolysis, citric acid cycle, and electron transport.
In animals, like humans, waste products of aerobic respiration is, water and carbon dioxide, and waste product of anaerobic respiration are lacic acid.
