TRUE OR FALSE? When energy changes form, some of the energy changes to heat.

The substance in the glass is a mixture.

Types of a mixture

A mixture is the combination of two or more substances that are not related leading to the formation of either uniformly or unevenly formed solution.

There are two main types of mixture which includes:

• Heterogeneous mixture: These are the type of mixture that are not evenly distributed. Example is the mixture of sand and water.

• Homogeneousmixture: This is the type of mixture that appears evenly or uniformly distributed. Example is mixture of water and salt.

Therefore, the mixture of salt and water is a homogeneous type of mixture.

>Conservation is, preservation, protection, or restoration of the natural environment, natural ecosystems, vegetation, and wildlife

>Two examples are;

* turn off the water from the bathroom thing the sink while brushing your teeth or something

* If you don't drink all your water from the water bottle use it to water a plant or something ✌

Answer:

Conservation is using a resource wisely so it will not be used up. Possible examples include: take shorter showers; fill the bathtub only halfway; do not run water while scrubbing vegetables or brushing teeth; water lawns early in the morning or late in the afternoon; and run the washing machine only for a full load.

Explanation:

Answer:

3) Each sample has the same number of molecules

Explanation:

1 mol are 6,022x10²³ particles. Moles of a chemical substance represent the number of molecules that this chemical has.

Thus, one mol of oxygen are 6,022x10²³ molecules of oxygen and one mol of nitrogen are 6,022x10²³ molecules of nitrogen.

Right answer is:

3) Each sample has the same number of molecules.

Scientists would deal with the aspect of cloning a particular gene into a bacterium or making of hybridoma cells that will produce the particular required protein. Engineers will then design and develop a bioreactor which is a programmed instrument that avails the required substances to the cells/bacteria in specific amounts and at particular time periods to grow and reproduce the cells in large amounts.
