It is important that blood flow varies throughout different organs because of differences in the metabolic activities of the different organs.
What is the circulatory system?The circulatory system refers to the system of organs and tissues which are involved in the circulation of blood around the body.
The circulatory system performs the essential function of delivering nutrients to tissues and cells as well as removing metabolic waste from them.
Since the different organs in the body perform specialized functions, some organs are actively involved in metabolic activities, therefore need greater blood flow.
Therefore, blood flow varies throughout different organs because of differences in their metabolic activities.

Which of the following is a distinction between the Krebs cycle in eukaryotes and prokaryotes?
A. Prokaryotes do not use acetyl CoA.
B. The process occurs in the cytoplasm of Eukaryotes.
C. The process occurs in the mitochondria of Eukaryotes.
D. Eukaryotes do not produce carbon dioxide.
E. Prokaryotes do not produce FADH2.
Answer:
C. The process occurs in the mitochondria of Eukaryotes.
Explanation:
In eukaryotes: glycolysis takes place within cytosol, Krebs cycle within mitochondrial matrix & ETC within inner mitochondrial membrane. Prokaryotes undergo binary fission(only cytokinesis) & conjugation.Prokaryotes undergo binary fission(only cytokinesis) & conjugation. Eukaryotes perform mitosis, meiosis(both karyokinesis and cytokinesis).Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.
Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

Explain how a mutation may affect the evolution of a species.
Answer:
Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.

The diagram shows that a cottontail rabbit gained 400 KJ of energy when it consumed a plant. The cottontail rabbit was later eaten by a barn owl, but the owl only gained 50 KJ of energy from consuming the rabbit. Which statement best explains why only 50 KJ of energy was passed on to the barn owl?
Answer: The total energy passed from one level to the next is only about one-tenth of the energy received from the previous organism. This means that an animal eating a plant will only get about ten percent of the energy that is stored in the plant
Explanation: it may be lost as faeces, thermal energy or may not be digested properly to get the derived energy

Why can’t penguin fly?
Answer:
No they cannot fly
Explanation:
Penguins dont have any feather to fly with
Answer:
Well, in a sense they really do fly, only through the water, not through the air. Their wing bones are fused straight, making the wing rigid and powerful like a flipper. Penguins don't really need to fly because they dive deep, and swim so that they can catch their prey. Their bodies have huge fat supplies, heavy muscles, and densely packed feathers. There’s no way they could fly with such short wings and heavy bodies.

III. It only affects an individual in a population.
I, II, and III
I and II
II and III
I only
Answer: I and II
Explanation: so basically, when adaptation occurs, it usually happens over a long period of time due to climate, predators, etc. because of these adversities, Genetic mutations occur, helping that animal and its species as a whole survive, which checks number 2. number one is also correct because adaptation can not be predicted. it happens randomly at some point in time. 3 is incorrect because multiple offspring in a species could have adaptations that provide more of an advantage.
