All of the following except C.Sleeping releases Dopamine naturally
I hoped this helps:)
If the allele frequency of a gene for brown fur is increasing from 15 to 25 percent, the population of the bears is evolving.
Mitochondria are often referred to as the powerhouse of the cell. They are small structures within a cell that are made up of two membranes and a matrix. The membrane is where the chemical reactions occur and the matrix is where the fluid is held. Mitochondria are a part of eukaryotic cells.
The main job of mitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then in turn used by the cell to carry out various functions.
Answer:
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring
Explanation:
The term resistance in the exposed example refers to an inheritable change in the weed population sensitivity, which is reflected in the consecutive failure of the chemical effects on the herb population.
Herbicide might produce a genetic modification in the weed, leading individuals to survive under the effects of the chemical. The plants evolve with the capability of tolerating the chemical dose that is usually used to destroy a normal population of plagues.
Resistance to the toxic is associated with mutations in some of the genes.
A mutation is a change in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
- The selective pressure or modeling environmental factor is the triazine herbicide
- The weed´s response to herbicide is the survival of only those that carry mutations.
- Natural selection benefits these mutations.
- The mutated herbs survive, become more resistant, and pass the mutation to their offspring.
