Soil is often rich and soft.
The vas deferens are a fibromuscular tube which connect to the epididymis, and is an excretory duct of the testis.

Cells move to new positions as an embryo establishes its three germ tissue layers during option(d) i.e, gastrulation.
A young developmental process known as gastrulation occurs when an embryo changes from a one-dimensional layer of epithelial cells (blastula) to a multilayered, multidimensional structure known as the gastrula.
The three embryonic germ layers—the endoderm, ectoderm, and mesoderm—are positioned during gastrulation. Later, these layers grow into specific body systems. The three layers of embryonic tissue, or germ layers, are created as a result of gastrulation. These cells will multiply, move, and differentiate during development into the four main tissues: epithelial tissue, connective tissue, muscle tissue, and nerve tissue.
