b. wind
c. a top predator
d. a snake
Answer:
The correct answer is b. wind.
Explanation:
The wind does not have a heartbeat.
The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as nucleus, ribosomes and mitochondria which are crucial for protein synthesis, assembly and repair. In other words they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
Red blood cells (RBCs) are unable to replace damaged proteins because they lack a nucleus and organelles, including mitochondria. Instead, new RBCs are constantly produced in the bone marrow to replace damaged or aged ones. When RBCs are damaged or aged, macrophages phagocytize them.
Red blood cells (RBCs) are unable to replace damaged proteins because they lack a nucleus and organelles, including mitochondria. This means that RBCs cannot synthesize new proteins to replace damaged ones. Instead, RBCs have a limited lifespan and are constantly being replaced by new RBCs produced in the bone marrow. When RBCs are damaged or aged, they are phagocytized by macrophages in the spleen, liver, and bone marrow.

Such a person exhibit knowledge of the subject or topic in which the research has been conducted. The reviewer reads the written document related to the research, rectifies the mistakes and gives opinion for the betterment of the research outcome.
b. jumping rope
c. push-ups
d. none of the above
Answer;
B. Jumping rope
Explanation;
Jumping rope is not an anaerobic exercise but an aerobic exercise.
Anaerobic exercise is a form of high intensity exercise that increase the oxygen debt. However since the muscles require oxygen to maintain prolonged exertion, anaerobic exercises can only last for short periods of time.
Examples of anaerobic activity sprinting, high-intensity interval training, power lifting and most athletic sports.
Aerobic exercise refers to cardio, which means exercise that requires pumping of the oxygenated blood through the heart to deliver the oxygen to the muscles which were working. Out of the given options, jumping rope is an example of an anaerobic exercise.
Further Explanation:
Exercise refers to any activity which maintains or enhances the overall health, wellness, and physical fitness. This is done for many reasons to help in improving the strength, growth, avoiding aging, and developing muscles. This can be segregated into 2 kinds, namely, aerobic and anaerobic exercise.
Aerobic exercise refers to those exercises which require energy. When an individual exercise aerobically then the body utilizes glycogen as well as fat as fuel. There is low to mid-level of exertion that can be assisted for a long period of time. As the individual breathe more with exertion, the CO2 (carbon dioxide) is eliminated from the body.
Common examples of this are :
• Running
• Biking
• Jumping rope
• Swimming
Anaerobic exercise, on the other hand, refers to those exercises wherein oxygen is absent. When an individual exercise anaerobically, glycogen is utilized as a fuel. During this, the body accumulates lactic acid that causes discomfort as well as fatigue at the comfort levels. For this reason, high-intensity exercise occurs in short bursts. Common examples of this are weight lifting, sprinting, and push-ups.
