Answer:
adaptations such as warning coloration, alarm calls and other signals, camouflage, mimicry of well-defended species, and defensive spines and chemicals.
Hope this helps with whatever you are working on :)
Explanation:
You can carry out a test ,
1- take a sample of the air in a test tube
2-add limewater to the test tube
3- result : if it turns milky/cloudy it has microorganisms
4- reason: because every microorganism respires , and so it produces Carbon dioxide .
and limewater is the test to show the presence of Carbon dioxide .
E.coli because e coli is a bacteria.
Answer:
Genetic drift
Explanation:
Genetic drift is defined as the random change in allelic frequencies from one generation to the other.
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
Answer:
Water is polar and oil is nonpolar so the substances won't mix.
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water.
