Answer and Explanation:
Tracheophyte plants, also known as vascular plants, are those that possess a supportive tissue that can also conduct fluids -The Xileme- and another tissue that conducts nutritious elements produced by photosynthesis -The Phloem-. These plants have a root (basically underground), a stem (aerial), and leaves. All of them together form the corm. And the corm counts with these vascular tissues to which we referred before.
There are different types of Tracheophyte plants, some of them produce seeds to reproduce and disperse -Spermatophyta- and some others reproduce and disperse by spores -Pteridophyta-. This last seedless group corresponds to ferns and other similar plants.
Pteridophytes characterizes for having a sporophyte that has stems with leaves and a root. It also has primitive xylem composed by tracheids and phloem, both of them formed by vascular bundles located in a central cylinder.
Spores are its dispersion units and are responsible for colonizing new areas. They also constitute the resistance units under extremely unfavorable conditions.
Their life cycle is composed of the asexual phase (sporophytic phase) and the sexual phase (gametophytic).
- The <u>sporophyte</u>, the dominant asexual generation, it is a perennial and diploid structure. Its aerial part might disappear during unfavorable seasons, but it reappears during spring or summer. The sporophyte is in charge of asexual reproduction
- The<u> gametophyte</u>, instead, is and haploid structure, ephemeral and must be in the water for its survival, and for sexual reproduction to be successful. In the presence of water, masculine gametophyte -antherozoids- are released and they swim to the archegonium to meet the ovocell. Antherozoids can swim because they have flagella. After fertilization, a new sporophyte is produced.
Experiments with faulty design or inconsistent data:
-decreases the experiment's reliability and validity
- wastes time and resources
- destroys the scientist's credibility in their field
- may lead to issues of safety to the experimenter/s due to faulty design
- is discouraged especially in hard sciences where data obtained should be accurate and precise

Three of the major characteristics used to classify organisms are cell structure, mode of nutrition and cellularity. These characteristics help scientists determine how organisms are similar to each other as well as how they are different from each other.
Answer:
Most people give credit to Benjamin Franklin for discovering electricity. ... In 1752, Franklin conducted his famous kite experiment. In order to show that lightning was electricity, he flew a kite during a thunderstorm. He tied a metal key to the kite string to conduct the electricity.
Answer:
<h2><u>
Median</u></h2>
Explanation:
The <u><em>median </em></u>is the value separating the higher half from the lower half of a data sample. For a data set, it may be thought of as the "middle" value. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth largest, and also the fourth smallest,
