In a series of experiments, Avery treated heat-killed nonvirulent s bacteria with enzymes that degraded the proteins, dna, and r

na of the s bacteria, then mixed this with nonvirulent r bacteria. S cells grew in all cases except the samples with degraded dna. What did this demonstrate

Answer:

<u><em>C. DNA from the S bacteria is necessary for bacterial transformation to occur.</em></u>

Explanation:

These series of experiments determined that DNA is the genetic material which gives rise to a particular type of cell. As we can see, the S bacteria with degraded proteins were able to grow when the proteins and RNA were degraded. But they were not able to grow when their DNA was degraded. This experiment proved that proteins or RNA are not the genetic material, rather DNA is the material related to inheritance.

The answer is; hydrothermal, geothermal, and wind

Hydrothermal, taped from the biggest river on the state contributes approximately 60% of the energy in the state. Geothermal is second,approximately 30% while wind power contributes approximately 10%.


The costs of the electricity in the state are relatively cheap compared with states whose main source of energy is hydrocarbon fuels.   Geothermal power is the cheapest (even though initial investment is prohibitive). Hydrothermal is slightly expensive than geothermal due to the maintenance required and also  is prone to fluctuations of the river regime. Winds are also cheap but initial investment if the wind farm is high.



Hydrothermal energy has the biggest environmental impact compared to the other two. Due to the walls of the dam on the river, migration of some aquatic species is impeded. The reduced flow of water (and sediments) downstream of the dam also impact these ecosystems. Geothermal and wind energy sources have a very minimal environmental impact on the environment .


The state could increase electronics with low power consumption (such as LED lights) in the market for availability to the population. This would be followed by a sensitization campaign on the ideal use of power in the household to conserve power when not in use.

Earths four major spheres are the?
aleksklad [387]

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air)...

I hope this helps you with biology...
