Following are the choices:
a. nonrenewable energy sources b. renewable energy sources
c. carbon sequestration d. recycled plastics
The correct answer is:
b. renewable energy sources
Explanation:
Renewable energy is energy that is obtained from renewable resources, which are naturally provided on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy compares to the provision of energy via renewable sources which are simply replaced fast enough as being used.
Cells were first identified by Robert Hooke in 1665 when he observed the box-like structures in cork tissue under a microscope. In the 1670s, Antoine van Leeuwenhoek became the first to observe living cells. Both their work was instrumental to the understanding of cells and cell theory.
In 1665, experimental scientist Robert Hooke was the first to identify cells. He used the term 'cell' to describe the box-like structures he observed in a cork tissue using a lens, as documented in his publication Micrographic. Hooke's concept of a cell was based on his microscopic observation of the dead cork tissue. He likened the tiny subdivisions in the cork to the small rooms, or cells, that monks resided in.
Antoine van Leeuwenhoek, in the 1670s, became the first person to observe living cells, specifically bacteria and protozoa. Advances in lenses, microscope construction, and staining techniques throughout the years enabled the viewing of components within cells, further refining our understanding of cell structure and function.

In the chemical process of photosynthesis water is a chemical change
I hope that's help !
Answer:
Water is a Reactant
Explanation:
I already did the quiz.
When chemical, biological and ecological changes occur the plants start to die and decompose, fish die, carbon dioxide is released. Hence the correct option is B.
Ecological change also known as environmental change is defined as the alteration or disturbance of the environment usually caused by human impacts and natural ecological processes. Environmental changes include various factors, such as natural disasters, human interference, or animal interactions.
The ecological changes are affected by the following reasons such as habitat change, climate change, invasive species, overexploitation, and pollution. When chemical, biological and ecological changes occur the plants start to die in the pond and start to decompose, fish die, carbon dioxide is released.
Hence the correct option is B.

Answer:
The diagram of the virus is given below.
Explanation:
Virus may be defined as the simple organism that contain DNA or RNA as their genetic material, surface area is covered with protein coat. Body is divided into head, neck collar and tail fibers. Virus requires a host organism for its growth and reproduction. Virus can affect plants, animals, bacteria and microorganisms.
Viruses are very small, typically between 20 and 300 nanometers in diameter and are so small that they can only be seen with an electron microscope.
Viruses are not considered to be living organisms because they do not have their own metabolism. They need to infect a host cell in order to reproduce. Once a virus infects a host cell, it takes over the cell's machinery and uses it to make more copies of itself.
Viruses can cause a wide variety of diseases, including the common cold, the flu, and AIDS. There is no cure for most viral diseases, but there are treatments that can help to relieve the symptoms.
