Answer:
Cytoskeleton
Explanation:
The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement. Cytoskeleton is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition including microtubules, actin filaments and intermediate filaments.

Legumes harbor nitrogen-fixing bacteria and are therefore good crops to grow to replenish the soil. Most nitrogen fixation occurs naturally, in the soil, by bacteria.
Nitrogen fixation and exchange of form that occurs in the soil. Some bacteria attach to plant roots and have a symbiotic relationship that is beneficial to both the plant and the bacteria with the plant. Nitrogen fixing bacteria accomplish more than 90 percent of all nitrogen fixation and therefore play an important role in the nitrogen cycle. processes that can fix nitrogen atmospheric, be process and biological. Atmospheric fixation occurs when the high temperature of lightning splits nitrogen gas so that it unites with oxygen and moisture in the air to form nitrates that fall to the ground. Nitrogen fixation occurs among some termites and fungi. It occurs naturally in the air through the production of NOx by lightning. All biological reactions that involve the process of nitrogen fixation are catalyzed by enzymes called nitrogenases.

Explanation:
In onlooker play a child actively observes other children playing and does not attempt to enter into the activity; the child is interested only in observation and not in participation. In parallel play children play independently among other children. In pretend play children act out any event of daily life and practice the roles and identities as established in their surroundings. In associative play children play together and are engaged in a similar or identical activity.
