Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.

Explanation:
Answer:
Soil erosion.
Explanation:
No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.
Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.
Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.
Answer:
Science has a central role in shaping what count as environmental problems. This has been evident most recently in the success of planetary science and environmental activism in stimulating awareness and discussion of global environmental problems. We advance three propositions about the special relationship between environmental science and politics: (1) in the formulation of science, not just in its application, certain courses of action are facilitated over others; (2) in global environmental discourse, moral and technocratic views of social action have been privileged; and (3) global environmental change, as science and movement ideology, is vulnerable to deconstructive pressures. These stem from different nations and differentiated social groups within nations having different interests in causing and alleviating environmental problems. We develop these propositions through a reconstruction of The Limits to Growth study of the early 1970s, make extensions to current studies of the human/social impacts of climate change, and review current sources of opposition to global and political formulations of environmental issues.
