Answer:
increasing[1], higher[2], space[3], food[4], climate change[5].
Explanation:
Because global temperatures are <u>increasing[1]</u>, some species are seeking out <u>higher[2]</u> elevations in the Himalayas to colonize. Scientists were worried that these organisms would not have enough <u>space[3]</u> to live, but they have found that there is adequate <u>food[4]</u> at higher elevations. This movement may help these organisms survive the effects of <u>climate change[5].</u>
(Although am positive about 1, 2 and 5, you will need to double check 3 and 4. What I can tell you is that I don't think lifespan has to do with 3 or 4. I chose space and food simply due to the thought that more species moving to higher elevations allows for less space to live, but more prey to be hunted easier.)
It is because that's a place where no one lives so they're safe.
Answer:
2. have no negative particle
Explanation:
Helium atoms contains 2 neutrons and 2 protons (or 2 electrons). Thus, it has a mass number of 4 and atomic number of 2.
Alpha particles are heavy and positively charged, which make them to be deflected in a magnetic or electric charge. So, the helium atoms used as alpha particles for the gold foil experiment must have no negative particle.
Answer: Las orugas, larvas de mariposas y polillas, se alimentan casi exclusivamente de plantas. La mayoría de las orugas mastican felizmente las hojas, aunque algunas se alimentan de otras partes de la planta, como semillas o flores, mientras que durante la etapa de adulto, la mariposa se alimenta de néctar y pasa de ser un herbívoro a ser un importante polinizador.
