Answer:
A and B only.
Explanation:
DNA is present as the genetic material of the living organism. Hershey and Chase experiments confirmed that only DNA is transmitted from one generation to the next generation.
They used radioactive phosphorus and sulfur and infects the cells with bacteriophage. The radioactivity labelled with phosphorus is present in the next generation whereas the radioactive sulfur molecules are not present in the next generation. DNA contains phosphorus whereas sulfur is present in the proteins.
Thus, the correct answer is option (D).
Answer:
1.The cell membranes main trait is its selective permeability, which means that it allows more substances to cross it easily, but not others. small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion but ions (charged molecules) and larger molecules typically cannot.
2. The structure is called a lipid bilayer because it is composed of two layers of fat cells organized in two sheets. the lipid bilayer is typically about five nanometers thick and surrounds all cells providing the cell membrane structure.
3. Osmosis.osmosis is the movement of water across a membrane from an area of low solute concentration to an area of high solute concentration.
4. Active transport. during active transport substances move against the concentration gradient, from an area of low concentration to an area of high concentration. this process is active because it requires the use of energy (usually in the form of ATP). it is the opposite of passive transport.

Answer:
Remove organic waste, Reduce packaging, eliminate bottled water, give food waste to animals.
Explanation:
Organic waste, Reduce packaging, eliminate bottled water, give food waste to animals are the some strategies to reduce the waste streams. The Organic waste in the water streams can be used as a fertilizer to the plants. The portion of Organic waste is large in the waste stream so its removal is good for the reduction in waste stream as well as for the crops. Avoid throwing packages and bottles in the waste water and reuse these packages and bottles through recycling process. Food waste that are thrown in the waste water can be used as feed to animals because there is a lot of nutrients present in it.
Answer:
C. a high second law efficiency due to use of solar panels on the house.
Explanation:
Second Law efficiency is the rational efficiency that computes the effectiveness of the system relative to its performance. The efficiency measure is the increase in output with the same level of input. Energy efficient system are high second law efficiency. They save electricity and use alternative sources like, solar panels, wind energy and others.
A cubit is an ancient measurement that measures length
the problem with using cubits is that the size may vary so it isn’t precise
the benefits of standardizing measurement is that they are precise and do not vary unlike the cubits
