Answer:
Explanation:
This is because ferns are vascular plants i.e they have vascular tissues which are xylem and phloems which help to conduct water and nutrients while mosses are non vascular plants.
2. Ferns sporophytes are differentiated into true leaves, stems and true roots while mosses lack true roots, stems and leaves.
Underground stems are modified part of plants that are derived from stem tissues which grow under the ground. Underground stems grow beneath the soil. Examples include Rhizomes, ginger, tubers e t.c.
Answer:
Size of particle.
Explanation:
Size of the particles that are diffusing is the factors that greatly affect the rate of diffusion. The rate of diffusion decreases if the thickness of the membrane becomes doubled while on the other hand, if the surface area of the membrane increases it doubled the rate of diffusion of the cell. If the size of particles is very small so it will diffuse if the membrane has double thickness.
High efficiency particulate arrestor is a type of air filter that can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns. The HEPA filter does not remove vapors or gases.
HEPA air purifiers have some level of activated carbon-based material to absorb odors and chemicals .HEPA filters claim to remove particles like dust, allergens and mold spores from the air. HEPA filters are made by haphazardly arranging the polypropylene or fiberglass fibers (between 0.5 and 2.0 µm). While sometimes the fibers are arranged in a mess, the fibers can pass air through and trap some of the particles.

Some foods and eating patterns may make it easier to keep obesity in check. Healthy food choices and diet patterns that help prevent heart disease, diabetes, and other chronic conditions may also help to prevent weight gain.
Eat whole foods-whole grains, vegetables, fruits, nuts, healthful sources of protein (fish, poultry, beans), and plant oils. Processed food should be minimal. Limit sugared beverages, refined grains, potatoes, red and processed meats, and other highly processed foods, such as fast food.
