How do joints work in the body?
How do joints work in the body? Joints allow our bodies to move in many ways. Some joints open and close like a hinge (such as knees and elbows), whereas others allow for more complicated movement — a shoulder or hip joint, for example, allows for backward, forward, sideways, and rotating movement. Which type of […]
What happens when vinegar and baking soda is combined?
What happens when vinegar and baking soda is combined? When baking soda is mixed with vinegar, something new is formed. The mixture quickly foams up with carbon dioxide gas. If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution. Sodium bicarbonate and acetic acid […]
Which ocean has lowest salinity?
Which ocean has lowest salinity? The Arctic Ocean’s Can you get salt from the ocean? From the Ocean to the Kitchen One gallon of water yields anywhere from half a cup to a full cup of salt, depending on its salinity. Almost any container will do, including plastic jugs, glass bottles and coolers. Why the […]
What is the formula for tension force?
What is the formula for tension force? The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration. What does negative stress indicate? Compressive stress has stress units (force per unit area), usually with negative values to indicate the compaction. However, in geotechnical engineering, compressive […]
What is an example of behavioral adaptation?
What is an example of behavioral adaptation? Behavioral Adaptation: Actions animals take to survive in their environments. Examples are hibernation, migration, and instincts.

Which type of mutation is the most dangerous?
Which type of mutation is the most dangerous? Frameshift mutations are generally much more serious and often more deadly than point mutations. Even though only a single nitrogen base is affected, as with point mutations, in this instance, the single base is either completely deleted or an extra one is inserted into the middle of […]
Is gravity really 9.8 meters per second?
Is gravity really 9.8 meters per second? Near Earth’s surface, gravitational acceleration is approximately 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres per second every second. What is gravity equal to? 9.8 m/s2 How do you solve for force? […]
