Answer:
Grasshoppers are primary consumers.
Explanation:
Autotrophs serve as primary producers in a food chain as they can make organic food by the process of photosynthesis. In the given food chain, tall grass is the primary producer. Grasshoppers derive their nutrition from the tall grass. The organisms that derive nutrition directly from the primary producers are said to be primary consumers. This makes grasshoppers primary consumers.
Mice the secondary consumers as they feed on the grasshoppers, the primary consumers. Red-tailed hawks are the top consumers in the given food chain. The bacteria, beetles, fungi, and worms are the decomposers that derive nutrition from the organic matter present in the dead bodies of the red-tailed hawks.
Answer:
The correct answer is option d.
Explanation:
An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.
One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.
In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.
Answer:
can someone help me on my question
Explanation:
According to productivity expert Odette Pollar, "to do more in a day, you must do less, not do everything faster." Pollar said that on the average if you spend not enough time and energy on those things you alone can do, you must look for tasks that others can and let them take over. Focus on the prize.<span>

To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.
In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.
- In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content. According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
- In basic solutions, the concentration of OH- ions is higher than that of H3O + ions. If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution. Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.
