Answer:
a drug called an antibiotic
Explanation:
A drug called antibiotics is a treatment used for a bacterial infection such as strep throat.
Antibiotics are medicines that are used to treat a wide range of bacterial infections.
These drugs destroys bacteria by preventing them from replicating and reproducing their copies. This way the strain is unable to continue one of its essential life function.
These substances are active against bacteria and provides a toxic condition for them to replicate.
Yes, this is true, and it is actually one of the organisms driving evolution! Some organisms develop mutations that are actually beneficial (better eye-sight, for example) and they're more likely to pass those to their children that individuals without those mutations!
Answer:
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
Answer:
One of the major goals of environmental science is to understand and to solve environmental problems. In order to accomplish this goal, scientists study two main types of interactions between humans and their environment. One area of focus is on how we use natural resources, such as water and plants.
Explanation:
Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.
The main difference is that mitosis occurs in body cells and meiosis occurs in sex cells. Mitosis produces identical daughter cells and meiosis produces genetically different daughter cells.
