Answer:
nonvascular because it lacks stems
Explanation:
Non-vascular plants, or bryophytes, are almost the most primitive forms of land vegetation. They lack the vascular tissue system (xylem and phloem) needed for transporting water and nutrients. Unlike angiosperms, non-vascular plants do not produce flowers, fruit, or seeds. They also lack true leaves, roots, and stems. Non-vascular plants are usually small, green mats of vegetation found in damp (wet) habitats. The lack of vascular tissue means that such plants must remain around moist environments.Just like other plants, non-vascular plants exhibit alternation of generations and cycle between sexual and asexual reproductive phases. The three main divisions of bryophytes are: Bryophyta (mosses), Hapatophyta (liverworts), and Anthocerotophyta (hornworts).
Answer:
Periodic Law.
Explanation:
The Periodic Law states that the physical and chemical properties of the elements repeat in a systematic and predictable way when the elements are arranged in order of increasing atomic number.
Many of the properties are repeated at intervals.
When the elements are arranged correctly, the trends in element properties become apparent and can be used to make predictions about unknown or unfamiliar elements, simply based on their placement on the table.
The half-life of the reaction is 101.9 min
<h3>First order reaction </h3>
When a reaction's pace and reactant concentration are inversely correlated, the process is known as a first-order reaction. To put it another way, the reaction rate doubles when the concentration does. One or two reactants can be present in a first-order reaction, as in the case of the decomposition process.
<h3>The half-life of first-order reaction:-</h3>
The amount of time it takes for the initial concentration of the reactant(s) to decrease by half is known as the half-life of a chemical reaction (abbreviated as "t1/2").
<h3 /><h3>Calculation:-</h3>
a→b
25% reacted means 75% remains
t=42 min
Rate constant
k=(2.303/t)(log a/a-x)
k=(2.303/42)(log 100/100-25 )
k=(0.054) (log 100/75)
k=(0.054)(0.1249)
k=0.0068 per min
half life
t1/2=(0.693/k)
=(0.693/0.0068)
=101.9 min
