Answer:
B
(The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.)
The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
Answer:
Ecosystem
Explanation:
The ecosystem includes a total of the abiotic and biotic components of a region. These components interact with each other and make the ecosystem self-sufficient in terms of energy and nutrients. Climatic conditions, physical factors, soil type, and its feature together make the non-living or abiotic part of an ecosystem. They interact among themselves and with the living components by nutrient cycling. All the species of living beings together make the biotic components of an ecosystem. They interact with each other by food chains and food webs.
Oceans are an example of the aquatic ecosystem while deserts are terrestrial ecosystems.
