Answer:
<em>Backyard bird feeding is a well known </em><em>type of human–untamed life </em><em>communication in specific regions of the northern and southern side of the equator.</em>
Explanation:
In territories where sustaining is mainstream in the Southern Hemisphere, supplemental encouraging may excessively profit acquainted winged creature species while driving with decreases of local species, possibly due to hetero specific competition.
However, Backyard bird feeders can bring about constructive outcomes on some feathered creature species, for example, improved overwinter endurance, expanded populace sizes and geographic range extension.

c. 4 I and III only
Explanation:
The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.
Cleavage Planes:
Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.
Cell Differentiation:
Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
