What does epinephrine do to the blood vessels?
Sympathetic stimulation (I'm guessing you mean your bodie's reaction in fight or flight) makes the blood vessles tighten, or constrict, hightening blood pressure. This is bad for you over long periods of time.
Which color fibers are slow oxidative fibers?
Slow oxidative fibers are typically red in color due to their high myoglobin content, which gives them their oxidative capacity for sustained contractions over long periods of time.
I am experiencing lower abdominal pressure almost like braxton hicks contractions i am also a little bloated Periods not due for two more weeks could i be pregnant?

Pattern of evolution where a species is stable for a long time then rapidly changes?
Punctuated equilibrium is a model of evolution in which species exhibit long periods of stasis, where little change occurs, punctuated by brief periods of rapid change. This theory suggests that most evolutionary change happens over relatively short periods of time during events like speciation.
What is the medical term meaning built-in or intrinsic rhythm of heart contractions?
AutorhythmicityThe heart is made of tissue that is specific to the cardiac muscle. The beating of the heart, in most healthy individuals, intrinsically arises in the SA (sino atrial node) in the upper right chamber of the heart. A normal resting heart rate is commonly considered to be between 60 and 100 beats per minute. In some very well trained athletes or in periods of meditation a normal resting heart rate may be less than 60.
Is there an animal always awake night and day?
Yes, some animals like certain marine mammals, birds, and insects exhibit behaviors that allow them to be active around the clock without sleeping for extended periods. However, they still have periods of rest or reduced activity to conserve energy.
What characteristics does an abnormal exercise program have?

What is a fast-moving glaciers that can move up to 6-kilometers per year?
An example of a fast-moving glacier that can move up to 6 kilometers per year is a surge glacier. Surge glaciers exhibit periods of rapid movement followed by periods of slower flow, which can result in significant advancements over short periods of time. This dynamic behavior is typically linked to internal glacier processes such as changes in basal conditions or ice thickness.
Does carbon and phosphorus have diagonal relationship?
Yes, carbon and phosphorus exhibit some characteristics of a diagonal relationship. They have similar atomic sizes and electronegativities, leading to some analogous chemical properties even though they are in different periods of the periodic table.
Do tigers have periods?
