Answer:
A. There are fossils of extinct ancestors of horseshoe crabs and the species is still alive today.
Explanation:
C and D have more to do with how it can be a fossil. It is a living fossil because its ancestors have been found in fossils, yet it continues to live today.
DNA We can change how cells interact
Explanation: The water cycle is also known as the hydrological cycle. It describes how water moves on, above, or just below the surface of our planet. Water molecules move between various locations - such as rivers, oceans and the atmosphere - by specific processes. Water can change state. Nitrogen compounds found in cells include proteins. Nitrogen from the air is converted into soluble ions that plant roots can absorb. It forms part of nitrogen compounds in the plants, and is then passed from one organism to the next. It is returned to the atmosphere as nitrogen gas. This is the nitrogen cycle. The carbon-oxygen cycle is the process by which plants use carbon dioxide for respiration during photosynthesis and produce oxygen. During this process, carbon dioxide becomes part of the plant, and when the plant dies in a carbon-rich state it is possible for it to become a fossil fuel.
Answer:
The biggest advantage is that they have a higher resolution and are therefore also able of a higher magnification (up to 2 million times). Light microscopes can show a useful magnification only up to 1000-2000 times. This is a physical limit imposed by the wavelength of the light.

Answer:
the process described in the question, described by Alessandro Volta refers to superconductivity, in which two metals connected by a conductive liquid produce a continuous transfer of electrons, these metals are considered superconductors since they do not have electrical resistance and this is always maintained and when the temperature is adequate, different from terms such as the resistance that is the impediment to the flow passage, or to the electric static in which the energy accumulation is maintained without movement or transfer or the electric current that is the energy in the same metal.
