"Coronary heart disease, North America’s number one cause of death, has been linked with the competitive, hard-driving, impatient, and (especially) anger-prone Type A personality. Under stress, the body of a reactive, hostile person secretes more of the hormones that accelerate the buildup of plaque on the heart’s artery walls. Type B personalities are more relaxed and easygoing. Chronic stress also contributes to persistent inflammation, which heightens the risk of clogged arteries and depression."

Answer:
The most diverse group of seedless vascular plants are <u>the ferns .</u>
Explanation:
Ferns -
Ferns are the most advance seedless vascular plants and is the most diverse group . Ferns have branching roots and large leaves . But the whisk ferns , have lack of roots and leaves due to evolutionary reduction . In the process of evolutionary reduction , the natural selection reduces the size of the structure which no longer favors the particular environment . Hence , Photosynthesis in whisk ferns takes place in their green stem .
Answer:
Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.
Carbon dioxide, oxygen, water, and acids may all cause chemical weathering. Mechanical weathering is the process of breaking a large rock into smaller pieces without changing the minerals in the rock. Mechanical weathering may be caused by frost, ice, plant roots, running water, or heat from the sun.
