Answer: An organisms response to stimulus would for example be shivering when you're cold
Explanation:
Scientists combine several well-testedtechniques to find out the ages of fossils. The most important are Relative Dating, in which fossils and layers of rock are placed in order from older to younger, and Radiometric Dating, which allows the actual ages of certain types of rock to be calculated.
Answer:
A.) White dwarfs are formed from the collapse of low mass stars, less than about 10 time the mass of the Sun. ... On the other hand, neutron stars are formed in the catastrophic collapse of the core of a massive star.
B. According to the HR diagram, a star with the surface temperature of 10,000 Kelvin is a star with a B spectral type. Moreover, if the star were on the main sequence, then it would have a luminosity nearly 100 times more than that of the sun.
C. After leaving the main sequence, Vega will become a class-M red giant and shed much of its mass, finally becoming a white dwarf. At present, Vega has more than twice the mass of the Sun and its bolometric luminosity is about 40 times the Sun's.
Explanation:
Answer:
The correct answer is c. Specific beak sizes are adaptations to the seeds of different species.
Explanation:
Allopatric speciation occurs when a population of a species is isolated geographically from their group. Then these isolated populations evolve in different species due to the selective pressure of natural selection.
The best example of allopatric speciation is seen in finches that live in the Galapagos Islands. These finches are isolated due to oceans on different islands of Galapagos and they developed different types of beaks according to the food they get on their island.
Some developed large blunt beaks to crack nuts, some developed long beaks to eat flowers and due to geographical isolation they did not interbreed and developed into a new species of finch. Therefore the correct answer is c.
