Answer: 1) jet streams are like rivers of wind high above in the atmosphere. these slim strips of strong winds have a huge influence on climate as they can push air masses around and affect weather patterns-- they form a bond between hot and cold air
2) lifting along fronts: when air masses interact. lifting also occurs along frontal boundaries as air masses of different temperature and moisture content interact with each other. the lifted air cools and the water vapor condences to form clouds in advance of the surface warm front
3) when the temperature difference between the cold and warm is large, thunderstorms and even tornadoes may form. thunderstorms can form at a cold front or within air masses. at a cold front, air can be forced upard quckly. within an air mass, uneven heating can produce convection and thunderstorms
Answer: The correct answer is-
Allopatric- option 2.
Sympatric - option 1.
Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).
In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.
On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.
Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.
Answer: Gastrocnemius, soleus, and Achilles tendon
Explanation:
The heel cord or achilles tendon is also known as calcaneal tendon is found at the back of the leg and is known to be the thickest bone in the human body.
It is attached to the plantaris, calf muscles (gastrocnemius) and soleus muscles. A person who wears heels regularly for a longer period of time suffers from pain and inflammation in muscles of leg.
These muscles helps in the walking and other movements of the legs. Wearing heals and walking is quite painful.
Anti- inflammatory combined with a local anesthetic that offers short term pain relief for degenerative disc disease. So a positive effect , in some cases saline can flush out chemicals that can cause the inflammation providing even more pain relief.
