People have manipulated the genome of horses and ponies in the lab to produce the breeds we know today
Dorsal root ganglia (DRG) are bundles of sensory neurons' somas (or cell bodies). Viruses such as Herpes infect DRG.
Transpiration is the rate of the water vapour exhalation by the plant cells through its opening pores. The correct blanks are guard cells and closing.
<h3>What is the structure of plant cells regulating transpiration?</h3>
Plant cells have certain specialized cell organelles that help in maintaining the rate of the carbon dioxide and the water content in their cells.
Stomata of the plant cells are specialized organelles that maintain the water and rate of transpiration by the plants. They have guard cells surrounding them that regulates their opening and closing.
The guard cells of the stomata form pores of the stomatal opening. The opening and the closing of the pores are regulated by the bulge and the carbon and the water intake and outtake of the cell is maintained.
Therefore, option A. <u>guard cells</u> and <u>closing </u>are the correct blanks.

On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option.
Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.

Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled.
In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>
