To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist. When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.

Annual range is the difference of the mean temperature between the hottest and the coldest month. 

<span>Cullowhee, NC,
Hottest month:
July - Ave. High: 85 </span>°F ; Ave. Low - 62 °F . Mean = (85+62)/2 = 73.5 °F<span>
Coldest month:
January - Ave. High: 48 </span>°F ; Ave. Low - 24 °F. Mean = (48+24)/2 =  36 °F
Annual Temperature range = 73.5 - 36 = 37.5 °F
<span>
Albuquerque, NM, - </span><span>largest annual temperature range
</span><span>Hottest Month:
July: Ave High: 90 </span>°F ; Ave. Low: 66 °F; Mean = (90 + 66) / 2 = 78 °F<span>
Coldest Month:
December: Ave High: 46 </span>°F ; Ave. Low 26 °F ; Mean = (46 + 26)/2 = 36 °F
Annual Temperature range = 78 - 36 = 42 °F
<span>
Los Angeles, CA - lowest annual temperature range</span>
Hottest Month:
August: Ave High: 79 °F ; Ave. Low: 62 °F ; Mean = (79 + 62) / 2 = 70.5 °F
Coldest Month:
December-March: Ave High: 67 °F ; Ave. Low: 51 °F ; Mean = (67 + 51) / 2= 59 °F

What is the anatomy of a bat's wing?
rusak2 [61]

Answer:A bat has a much more flexible wing structure. It is very much like a human arm and hand, except it has a thin membrane of skin (called the patagium) extending between the "hand" and the body, and between each finger bone. Bats can move the wing like a hand, essentially "swimming" through the air.

If the environment outside a cell is hypertonic, how will the cell maintain homeostasis?
USPshnik [31]

Answer:  Water will move outside of the cell.

Homeostasis is the ability of the cell to maintain the state of balance despite of changing external environmental conditions. Osmotic pressure is the hydrostatic pressure of water across the cell membrane. Tonicity is the measurement of this pressure. If the concentration of solutes on both sides of the membrane is equal then water will not move across the membrane. Osmotic pressure maintains the homeostasis of the cell. In hypertonicity osmotic pressure of the solution outside the cell is higher than the inside the cell. The water inside the cell will exit the cells in order to equalize the osmotic pressure on both sides, causing the cells to shrink.
