Dangling high above the ground, this rock climber relies on muscular strength to pull her weight higher and higher. However, muscles alone will not ensure her safety.
Explain why the muscular system cannot act alone to perform a skill such as rock climbing. Describe what other systems must be a part of this rock climber's game plan.
Answer:
The correct answer is - It has to act together with the nervous system mainly with other systems that assist in rock climbing.
Explanation:
Rock climbing is a physical activity or sport that could practice indoor or outdoor with mountains. It is a sport that requires physical and mental strength as it requires muscle strength, coordination, or balance, agility, endurance, and mental control over body and mind.
Muscular systems involve pulling the weight of an individual towards and leg muscles to hold whereas the nervous system controls or maintain the actions of muscles and also helps in balance the body of the climber. This neuromuscular set helps in maintains the muscle's tonicity in order to execute the action of climbing.
Other than these two main body systems there are cardiovascular system, circulatory system and respiratory system also helps in providing the conditions like increase oxygen input, high heartbeat, and more.
The excessive use of nitrogen-based fertilizers causes runoff that increases the nitrogen content of lakes and bays. The nitrogen directly affects the aquatic ecosystem by____
Answer:
C or the third answer choice
Explanation:
If algae excessively grows on the tops of the water, it can block sunlight. That will make the underwater plants die, and the animals that eat those underwater plants will slowly have less to eat if they can't adapt quickly enough. When the algae dies, it takes oxygen with it. If it take all of the oxygen in the water, that whole ecosystem could potentially die as well.
