Poison ivy is a weed that produces an oil which causes skin rashes. Scientists want to perform an experiment to see if poison iv

Answer:

In these experiments the control group is compared with the comparison group.

The control group will sometime be in the presence of carbon dioxide, and will be controlled, where the analyst or researcher will take an expert position and then will compare it evolutionarily with the comparison group that the ideal would be that there is not ever a carbon dioxide

Explanation:

If we have two poison ivy research groups that are representative of the poison ivy that the researchers are looking to investigate the results will have much better credibility and will be more reliable.

On the other hand, the comparison of the two groups makes it possible to rigorously analyze whether or not poison ivy grows in the presence of this gas.

HELP!!
Advocard [28]

Answer:

the average percentage of energy lost as heat

Explanation:

An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.

Answer:

D. Planting exotic shade plants in their yard and hiring a lawn company to tend to them.

Explanation:

Both grass and vegetables produce CO2. Vegetables produce as much CO2 as a car that's been driving 4.5 miles. Beef produces enough CO2 for 63 miles. This eliminates all of the answers except for D. Plants use CO2 in photosynthesis and give off O2. So not only will is reduce the CO2 output, it will provide you oxygen.

Examine the statement. A scientific theory can become a scientific law, but a scientific law cannot become a scientific theory.
Elena L [17]

Answer:

1.) True

Explanation:

A scientific theory can become a scientific law, but a scientific law cannot become a scientific theory.

A scientific theory is what is made to scientific law after many trials to prove the scientific theory is true. But after they changed a scientific theory to scientific law, it can't be changed back because it has been disproved many years later.

Hope it helps.
