Answer:
Cell wall, Vacule, Plastids
Explanation:
Answer:
It would make it possible to compare that species to other species at a level deeper than outward appearance
Explanation:
The proteins like hemoglobin and enzymes can be studied to see whether organism which are similar in form can also be related to each other. Its differences found in these proteins' amino acid sequences will present how closely or distantly related an organism is to another.
The process by which organisms create sugars (specifically glucose) from non-carbohydrate precursors is known as gluconeogenesis.
- The only energy source used by the brain, testes, erythrocytes, and renal medulla is glucose, with the exception of ketone bodies during fasting. There are three highly exergonic stages in glycolysis. Hexokinase, phosphofructokinase, and pyruvate kinase are among the enzymes involved in these additional regulatory stages. In biological processes, both forward and backward reactions are possible.
- Similar to glycolysis, but with the process going the other way, is gluconeogenesis. Fructose-1,6-bP, glucose-6-P, and pyruvate all undergo fairly spontaneous conversions in the process of gluconeogenesis, which is why these reactions are tightly controlled.
- For the organism to function properly, energy conservation is crucial. Gluconeogenesis is suppressed when there is an abundance of energy available.
Therefore, gluconeogenesis conserve more energy.

Answer:Wildebeest are considered keystone species because their presence has myriad effects on the ecosystem, unlike those of any other species. Wildebeest are the "lawnmowers" of the Serengeti grassland. They keep grass short which in turn reduces the frequency of fires.
Answer:
The order must be K2→K1, since the permanently active K1 allele (K1a) is able to propagate the signal onward even when its upstream activator K2 is inactive (K2i). The reverse order would have resulted in a failure to signal (K1a→K2i), since the permanently active K1a kinase would be attempting to activate a dead K2i kinase.
Explanation:
- You characterize a double mutant cell that contains K2 with type I mutation and K1 with type II
mutation.
- You observe that the response is seen even when no extracellular signal is provided.
- In the normal pathway, i f K1 activat es K2, we expect t his combinat ion of two m utants to show no response with or without ext racell ular signal. This is because no matt er how active K1 i s, it would be unable to act ivate a mutant K2 that i s an activit y defi cient. If we reverse the order, K2 activating K1, the above observati on is valid. Therefore, in the normal signaling pathway, K2 activates K1.
