Which of the following is not a difference between photosynthesis and cellular respiration?
Answer: D
Explanation: They both play an important role in the carbon cycle. Photosynthesis removed CO2 from the atmosphere while cellular respiration causes the release of CO2 into the atmosphere.
The others are major differences
Photosynthesis has as its products Starch and O2 while those of cellular respiration are water , CO2 and energy.
The materials needed for photosynthesis are water and CO2 while those for cellular respiration are starch and O2
Photosynthesis occurs in chloroplast while respiration takes place in mitochondria .
Thus the only non- difference is D.

how is hydro electricity produced step by step explanation
Answer:
ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
Explanation:
In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.

Which of the following examples is a non-renewable source of energy A.Wind B.hydroelectric C.Nuclear power D.Wood
Answer:
An example of non-renewable source of energy would be C) Nuclear power.
Explanation:
Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals, whilst Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
I hope this helps! Have a great day! -Olli :]
Nuclear power is a non-renewable source of energy. It is derived from the energy released by nuclear reactions, which are fueled by radioactive materials such as uranium or plutonium. Therefore, option (C) is correct.
What is nuclear power?Nuclear power is a form of energy that is generated from nuclear reactions. It involves the use of radioactive materials, such as uranium or plutonium, which undergo nuclear fission in a reactor to produce heat. This heat is then used to generate steam, which drives a turbine and produces electricity. Nuclear power plants are used to generate electricity for homes and businesses, and they are typically very efficient and reliable sources of energy.
However, nuclear power also has potential drawbacks, including the risk of radiation leaks or accidents, the long-term storage of radioactive waste, and concerns over nuclear proliferation. Despite these concerns, nuclear power remains an important component of the world's energy mix, and ongoing research is focused on developing safer and more sustainable nuclear technologies.

What is meant by signal transduction and what is its effect on the process of egg activation?
Answer:
The process by which a cell responds to substances outside the cell through signaling molecules found on the surface of and inside the cell. ... Signal transduction is important for cells to grow and work normally. Cells that have abnormal signaling molecules may become cancer cells. Also called cell signaling.
Egg activation, whether initiated by or independent of fertilization, induces a rise in intracellular calcium. This calcium increase often manifests as a signaling wave that traverses the egg and releases it from meiotic arrest and metabolic dormancy.
