Bryophytes never form xylem tissue, the special lignin- containing, water-conducting tissue that is found in the sporophytes of all vascular plants.
Isobars represent adjusted atmospheric pressure. This removes pressure discrepancies caused by the location's relation to sea level or altitude. Isobars are also adjusted when necessary so that they never cross or touch. Weather maps with isobars give pressure information at a glance. They also give an approximation of wind direction because wind moves from high-pressure areas to low-pressure areas as large air masses move through the pressure differential.
I believe the correct answer is B. Detrital
embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants efficiently and cost-effectively.
Answer:
DNA is double-stranded, while RNA is single-stranded. RNA contains ribose as a sugar, while DNA contains deoxyribose. Also, three of the nitrogenous bases are the same in the two types (adenine, cytosine, and guanine), but DNA contains thymine while RNA contains uracil.
