sedimentary bedrock in the Appalachian region was subjected to high temp and
pressure. Rocks which contain many minerals ex: granite is called polymineralic.
The relevant field is astrobiology, the most highly funded branch of science that has the least scientific evidence supporting it. It encompasses cosmology, chemistry, geology, astrophysics, and biology predominantly and is exploring and attempting to generate knowledge on every aspect of naturalistic investigation of panspermia, habitability of exoplanets, energy sources in the cosmos, potential astro-intelligence, and composition of meteors, comets, asteroids, planets, solar systems and galaxies. The scope of astrobiology must accommodate virtually all of physical reality to be truly comprehensive.
Astrobiology is not funded well enough for the scope of the task, but is driving much of the science universe exploration projects to try to answer one of the fundamental questions of human history, is there other life and how did life come into being. Panspermia, non-directed (biochemical compounds from extraterrestrial sources of any type) and directed (intentional or non-intentional alien transmitted sources) are a prime astrobiological theoretical field and the search for extraterrestrial intelligence,SETI, is also a prime focus of astrobiology,
Photosynthesis, which is the process through which some living organisms, including most plants and some fungi, make their own food, produces oxygen as a waste product.<span> The process of photosynthesis in plants is the reverse of the respiration process in humans. While humans breathe in oxygen and expel carbon dioxide, plants ingest carbon dioxide and dispel oxygen.</span>
Answer:
C) behavioral isolation
Explanation:
The mechanisms of reproductive isolation that prevent the formation of a zygote by interbreeding between the individuals of two different species are called pre-zygotic isolation mechanisms. Behavioral isolation is one of such pre-zygotic isolation mechanisms. It includes the exchange of specific signals between the individuals of the same species before mating. Such specific courtship behaviors represent behavioral isolation.
Different species of fruit flies exhibit specific courtship behaviors such as fighting and display to attract the females of the same species only. These signals are not identified by females of the other species. It represents behavioral isolation.
A country like China would probably be in Stage 4 of the population with the low birth rate and low death rate due to their economic power have technology to prolong and save their citizen from diease and condoms
