The correct answer is A. Is that which benefits others while causing a disadvantage to the individual.
Explanation:
In biology, altruistic behavior occurs as one organism actions benefit other organisms either because these actions increase the reproductive fitness or the chances an organism survives and prevails over time. Additionally, altruistic behavior implies there is a disadvantage for the organisms acting in the benefit of others. For example, wolves or similar animals take food to those that did not participate in hunting, which means they help other wolves to survive on their own cost as this means less food for those that hunted. According to this, altruistic behavior "is that which benefits others while causing a disadvantage to the individual".

Answer:
The correct answer will be
1. Striated
2. Multiple
3. Broken down
4. Tendon
Explanation:
Skeletal muscles are the voluntary muscles found in the human body.
These muscles are made up of muscle fibers or muscle cells which look striated in appearance with many peripheral nuclei. The muscle helps in the locomotion of the body through controlled actions which help in the multiple types of movement.
The muscle moves when it receives impulse signals from the CNS which leads to the utilization of the ATP, the ATP is broken down which helps in the contraction of the muscle. The muscle is connected to the bone via a connective tissue called tendon, as the muscle contracts, it moves the tendon which helps in the locomotion.
Thus, the marked answers are the correct options.
