The main answer is that the removal of a keystone species from a community can have a significant impact on the entire ecosystem.
An explanation of this is that keystone species often play a critical role in maintaining the balance and structure of their community. Just as the centerpiece of an archway is necessary for the archway to remain standing, a keystone species is necessary for the community to function properly. Without it, the ecosystem may become unstable and could even collapse.
The best analogy to describe the effect of a keystone species removal on a community is the removal of the centerpiece of an archway.
A keystone species plays a critical role in holding the community together. Its impact on the community is significant, making it a keystone species. When it is removed, much like the centerpiece of an archway, the entire community structure can collapse or become significantly altered, as the other species within the community depend on the keystone species for balance and stability.

Organisms vary considerably in genome size. Which of the following explains most of this variation:
(a) Differences in the number of protein coding genes
(b) Differences in the number ribosomal RNA genes
(c) Differences in the number of pseudogenes
(d) Differences in the number of mobile genetic elements
The variation in genome size among different organisms is primarily due to differences in the number of protein-coding genes. While all organisms have some ribosomal RNA genes, pseudogenes, and mobile genetic elements in their genome.
Their numbers are relatively small compared to the number of protein-coding genes. The size of a genome is typically correlated with the complexity of an organism, but even among organisms of similar complexity, there can be significant differences in genome size.
For example, humans have around 20,000 protein-coding genes, while the Japanese pufferfish has only around 19,000 despite having a genome that is one-eighth the size of the human genome. This is due to differences in the amount of non-coding DNA and the organization of the genome. Therefore, it is safe to say that the primary factor that explains most of the variation in genome size is differences in the number of protein-coding genes.

glycogen use during physical activity depends on all of these factors except _____.
Glycogen use during physical activity depends on all of these factors except the individual's blood type.
Glycogen is a complex carbohydrate that is stored in the liver and muscles and is the primary energy source during high-intensity exercise. Several factors can affect the use of glycogen during physical activity, including the intensity and duration of exercise, the individual's fitness level, and the type of diet they consume.
The intensity and duration of exercise determine the rate at which glycogen is depleted. High-intensity exercise and prolonged endurance exercise use glycogen at a faster rate than low-intensity exercise. The individual's fitness level also affects glycogen use, as trained individuals have higher glycogen stores and can use them more efficiently during exercise. Finally, the type of diet consumed can affect glycogen use, as a high-carbohydrate diet can increase glycogen stores, while a low-carbohydrate diet can deplete glycogen stores.
Blood type, however, has no direct effect on glycogen use during physical activity. Blood type refers to the antigens present on the surface of red blood cells and is not directly involved in energy metabolism.
In summary, glycogen use during physical activity depends on several factors, including the intensity and duration of exercise, the individual's fitness level, and the type of diet they consume. Blood type, however, does not have a direct effect on glycogen use during physical activity.

Which of the following events would most likely cause an animal to overeat and become obese?
A. destruction of its ventromedial hypothalamus
B. lowering its set point
C. stimulation of its ventromedial hypothalamus
D. destruction of its lateral hypothalamus
The hypothalamus plays a crucial role in regulating food intake and body weight. The ventromedial hypothalamus (VMH) and the lateral hypothalamus (LH) are two areas in the hypothalamus that are involved in controlling food intake.
The event that would most likely cause an animal to overeat and become obese is the destruction of its ventromedial hypothalamus (VMH). The VMH is responsible for inhibiting food intake and increasing energy expenditure, meaning that if it is destroyed, an animal will likely eat more and become obese. This was demonstrated in studies conducted in the 1950s, where rats with VMH lesions ate excessively and became obese.
Lowering the set point, or the level at which the body defends its weight, would also cause an animal to overeat and become obese. However, this is a more gradual process and not an event that occurs suddenly. Stimulation of the VMH would actually decrease food intake and not cause an animal to overeat.
The destruction of the LH, on the other hand, would cause a decrease in food intake and potentially lead to weight loss. In conclusion, the destruction of the VMH is the event most likely to cause an animal to overeat and become obese, as it disrupts the normal regulatory mechanisms for food intake and energy balance in the body.
