Answer:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
hope this helps :)
It is also a cheap energy source. After the initial investment is paid off, the cost of generating electricity is very low. Tidal energy has a high energy density, meaning that the tides store a larger amount of energy than most other forms of renewable energy, such as the wind.
but if i have to say a answer i would say low enviromental impact
Photosynthesis is measured by the amount of oxygen produced. Counting pondweed bubbles or using the Audus apparatus to determine the amount of gas evolved over time can both be used to quantify oxygen.
<h3>
What is photosynthesis?</h3>
Photosynthesis is the conversion of light energy into chemical energy by green plants and other organisms. Light energy is collected and utilised by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
The forming bubbles are either counted or recorded using light barriers, which is difficult due to their small size and frequently changing ascent velocity. When gas bubbles produced during photosynthesis by aquatic plants leave the plants, they produce different sound pulses.
B. Because the gas collected contains water vapor in addition to oxygen, it is not pure oxygen.

Answer:
Stem cells cut and repair their own DNA to promote formation of new tissues.
Explanation:
Stem cells cut itself and then repair their own DNA as a mechanism of activating genes that promote the development of new tissues. Stem cells are special type of cells that the ability to develop into many different types of cell such as muscle cells, brain cells etc. These cells are also capable to repair damaged tissues in the body.
Organisms return carbon<span> dioxide to the </span>atmosphere<span> by respiration. It is not just </span>animals<span> that respire. Plants, algae and microorganisms do too. </span>Carbon<span> dioxide is also released into the </span>atmosphere<span> when fossil fuels such as coal and oil, and wood, are burned. hope this helps</span>
