Answer:
Molecular Biology of the Cell is the classic in-depth text reference in cell biology. By extracting fundamental concepts and meaning from this enormous and ever-growing field, the authors tell the story of cell biology, and create a coherent framework through which non-expert readers may approach the subject. Written in clear and concise language, and illustrated with original drawings, the book is enjoyable to read, and provides a sense of the excitement of modern biology. Molecular Biology of the Cell not only sets forth the current understanding of cell biology (updated as of Fall 2001), but also explores the intriguing implications and possibilities of that which remains unknown.
Explanation:
Goblet cells are those secretory cells or unicellular glands, which make and expel mucus can be found in simple columnar and pseudostratified columnar epithelia.
<h3>What are goblet cells? </h3>
They are goblet-shaped cells that have a basal nucleus and a cytoplasm loaded with mucins (the main component of mucus).
<h3>Characteristics of goblet cells</h3>
- It is present in the epithelia of the respiratory and digestive systems.
- Its main function is to secrete mucus, which protects and lubricates the inner surface of simple columnar and pseudostratified columnar epithelia.
Therefore, we can conclude that goblet cells are mucus-secreting cells present in epithelial linings.

Answer:
They are more likely to sprout near others of their species.
Explanation:
Answer:
Actin filament are one subunit type.
Intermediate filament has many subunit types.
Microtubules has two subunit types.
Intermediate filament has diverse cellular role.
Explanation:
Actin filament is a monomeric subunit of two types of filament in cells. The two types of filaments are the microfilaments which is one of the three components of the cytoskeleton and the thin filament which is a part of the contractile apparatus in muscle cells. Actin filaments are made up of identical actin protein arranged in a long spiral chain. Actin filaments play a major role in cytokinesis and in cell movement.
Intermediate filament have a strong and rope-like structure. Intermediate filaments are composed of various proteins, depending on the type of cells they are found. The play a significant role by working in tandem with microtubules to provide strength and support do flagile tubule structures.
Microtubules contains two polypeptide subunits in which the dimers of this subunits string together to form long strands called the protofilament. They are long and cylindrical in structure. They perform a variety of functions which include the determination of cell shape, involvement in cell movement and in the position of organelles in cells.

Explanation:
Vegetation reduces surface runoff hence reducing soil erosion in several ways. The roots of plants bind together tightly the particles of the soil so it is not easy for erosion agents to carry the soi. The organic matter produced by this vegetation provides organic matter in which the soil particles bind tightly into humus that has larger particles that are not easily carried by elements of erosion. The vegetation also breaks winds and surface runoffs hence reducing their energy and their capacity to carry soil particles. Therefore, without vegetation, soil is exposed and vulnerable to agents of erosion.
