Answer:
Explanation:
Boil a pot of water that has been tested with a stainless steel dish that sits adequately on top of the pot, without falling in. When the water boils, turn off the stove, which eliminates the ignition source, then pour your ethanol into the bowl, and place it on top of the hot water pot
They found that some mutations that each produced mutant phenotypes separately yielded wild-type phenotypes when present together in the same DNA.
A mutation is a change in the nucleic acid sequence of an organism's genome, a virus' genome, or extrachromosomal DNA. DNA or RNA can be found in the viral genome. Errors that occur during mitosis, meiosis, or viral replication led to mutations. The term phenotype refers to all of an organism's observable traits that emerge from the interplay of its genotype (total genetic inheritance) and environment or mutation.
There are two different sorts of phenotypes: wild type and mutant phenotype. Wild type refers to people who have the normal phenotype that the bulk of the natural population possesses, whereas mutant refers to people who have a phenotype that differs from the normal population.

A dependant variable is a variable in an experiment that is being studied or measured. A dependent variable's value depends on another.
Keeping this in mind, the dependent variable would be plant growth over time. The plant's growth is affected by its light source, the amount of time it's in the light/darkness, and the species of plant.
Hope this helps!

Answer:
1. 20 units
2. 4 units
Explanation:
In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.
If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.
Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.
An ecosystem is like a machine that cycle matter by using Carbon.
Carbon is the answer.
