It can become an ion because it can lose or gain an electron. It can become a part of molecule because it can form covalent bond with other atoms to gain a full valence shell.
they are strongest between latitudes of 30°N and 60°N. but they move every year, "following the sun".
Answer:The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
The epimysium
each muscle is surrounded by a connective tissue sheath called the epimysium fascia, connective tissue outside the epimysium, surrounds and separates the muscles.
