Answer:
Muscle contraction is an example of mechanical contraction.
Explanation:
Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.
Muscle contraction is based on force and length.
The process of skeletal muscle contraction is an energy requiring process.
In order to perform mechanical work,actin and myosin utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.
In a working muscle,glucose is released from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.
Answer:
Deliver water, nutrients, amino acids, etc to the rest of the plant, and afir machanical supoort
Answer:
<u>Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.</u>

Answer:
The correct answer is option c. "multimale/multifemale".
Explanation:
One of the most common primate groups that could be found in nature are multimale/multifemale groups. This kind of primate grouping is seen more often when predation pressure is high. Only male or only females groups join forces to chase and attack predators more easily that diverse groups, therefore these groups are primate defense system against predators.
Answer:
It would harm the few plants that benefit from mutualistic relationships with mycorrhizal fungi
Explanation:
Mycorrhizal relationship is a symbiotic relationship between fungi and the roots of higher plants. While the plant provides the fungi with food, the fungi supply the plant with nutrients and water extracted from the soil.
<em>Hence, if a wide-spectrum fungicide is used in a forest and it kills all the fungi in the forest, it will affect all the plants that share beneficial relationship with fungi in the forest.</em>
