for question 1.) i am pretty sure of answer a.)
for question 2.) the answer is most likely b.)
i would recommend waiting for a second opinion. just to be safe.
Solar energy, wind energy, hydropower, geothermal energy, and biomass energy. These types of energy sources are different from fossil fuels, such as coal, oil, and natural gas.
Based on the description above, the molecular clock data
shows is that the Clams and Snails are more similar and related in structure
compared of the clams and squids. It is because it could be seen in the process
that organism are better in adapting to their environment in means of
increasing their number, survive and to pass on their traits to the next
generation.
Answer:
A. The temperatures are too high.
Explanation:
A desert is a region with extremes of temperatures and little to no rainfall.
Organic matter are the remains of organisms that have died. They are a very important component of soils.
Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.
Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.
Answer:
Natural selection
Explanation:
Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.
This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.
