Answer:
the proton and the neutron
Explanation:
An atom is made up of subatomic particles; neutrons, protons and electrons. The protons are positively charged subatomic particles found in the nucleus with a mass equal to 1.6 \times 10^{-27} kg. The electrons are negatively charged particles of an atom found in the orbital shells in constant motion. They have a mass equal to 9.1 \times 10^{-31} kg. The neutrons are particles found in the nucleus that have no charge and have a mass equal to 1.6 \times 10^{-27} kg. therefore protons and neutrons are similar in mass.
An orgainism is endangered when it is close to extinction...this happens when an organism is hunted down for its meat or other properties...
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
The subunit of proteins is one protein molecule that assembles with more protein molecules to make a protein complex.
Hope this helps! ;)
