The answer to the 3rd question is that chromosomes are tightly coiled bundles of DNA and carry many genes. For the 4th question, asexual reproduction can occur by binary fission and creates exact genetic copies of a parent.
That would be A.
Most antibiotics that are used for gram positive bacteria target the peptidoglycan cell wall, but the ones for gram negative bacteria are more advanced and specific and target the cell membrane and alter the cell’s function(processes of proteins and dna/gene expression).
That would be the sun. Hope this helps.
B. Plate count method!
I hope this helps. Enjoy the holidays.
Answer:
Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. The heat you feel in your body is the suns energy entering your body from the energy transfers that happen when you move.
Explanation:
Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light. The heat you feel in your body results from the energy transfers that happen when you move. When you sweat, your body expends energy to cool itself down. A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers.
