<u><em>Solar Energy and Biodiversity</em></u><em> are the 3 factors of Sustainability.</em>
Answer:
<em>B. Solar energy
</em>
<em>D. Biodiversity
</em>
Explanation:
Sustainable sources of energy are renewable sources of energy. Sustainable energy is the availability of energy to such an extent that it addresses the issues of the present without trading off the capacity of future ages to address their issues.
Sustainable energy incorporates all sustainable energy sources, for instance, hydroelectricity (electricity from water), biomass, geothermal (electricity from the Earth), wind (using windmill), wave, tidal and sun oriented energies. Renewable energy is the process but sustainable energy is our belief or mindset.
Answer:
The correct answer is both pumps use proteins to transport substances across the cell membrane.
Explanation:
Sodium potassium pump helps in the active transport or uphill transport of both sodium and potassium across the cell membrane against their concentration gradient.
Whereas Ca2+ATPase or calcium pump itself is a trans membrane or membrane spanning protein which helps in the transport of Ca2+ outside the cell to maintain electrochemical potential of Ca2+ ions.
Answer:
Gene flow
Explanation:
Evolution is the changes seen in the growth, development, features of a certain group of species during the cause of time. Evolution causes changes in the gene frequency of species from one generation to the next generation.
There are 5 important mechanisms of evolution and they are: Gene flow, mutation, genetic drift, natural selection and non random mating.
Gene flow as a mechanism of evolution is the exchange or transfer of genes between a group of species as they move from one place to another. Gene flow can either increase the rate of evolution or decrease it.
