Answer:
Globlet cells are found in the epithelial cells on the walls of trachea, bronchi, and villi and Fallopian tube. They are unicellular exocrine glands( ductless glands,do not secret hormones directly into the blood streams) which are columnar in shape, that is they are shaped like columns.
They function in secretions of Mucus containing MUCIN. The mucus lubricates the surrounding mucus membrane medium they are located. Mucin is the main major components of the mucus, and it is is jelly-like in nature.( Thus jelly-like nature of mucus is due to MUCIN contents. ) Glyco-protein(glycogen +protein; glycogen attachments to polypeptide chains), is its chemical components.The glyco-protein is produced by Carbohydrates.
Apart from the lubricating role, the mucus through the mucin it contains traps any foreign substances that is found in the passage they are deposited, and sweep them.Their jelly-like nature facilitated the trapping.For example in the bronchioles , trachea, and the female genitalia tracts, they traps bacteria and fungi with the mucus and clear with cillia.

Answer:
Almost all of the corn grown in the US is exported
Explanation:
The US is the largest producer and the largest consumer of corn and corn products in the world. The corn is used in both the human and the cattle diet, with a special accent on the cattle diet, as it is the primary food used for the tens of millions of cattle that the country has.

Despite being the largest producer of corn in the world, the US is not exporting a lot of its corn, but instead it is actually importing more corn, as the demand for it, and the versatility in its usage and well established in the American economy.
Answer: En la difusión facilitada, las moléculas solo se mueven con la ayuda de una proteína en la membrana. En difusión simple, las moléculas se mueven hacia abajo del gradiente de concentración, pero en la difusión facilitada las moléculas se mueven hacia arriba en el gradiente de concentración. La difusión simple es pasiva, pero la difusión facilitada es un proceso activo que utiliza energía.

Explanation:
The biopsychosocial approach is most directly concerned with assessing the relative contributions of heredity and experience to personality development (Option C)
- The Biopsychosocial Approach is an interdisciplinary model which was first developed by George Engel and Jon Romano (1977).
- The biopsychosocial approach is a type of model that recognizes biological (inheritance), psychological, and social (environmental) factors as well as the interactions among these factors to understand the health and illness state of an individual.
- Social factors include economical, environmental, and cultural factors (e.g. work concerns and family issues).
- Biological factors include both genetic and biochemical factors.
- According to this approach, both mind and body determine the health of the subject.

Not sure what you mean by dangerous. Charles Darwin had a theory on evolution called Natural Selection. This theory of his essentially states that the organisms that adapt best and most successfully to changes in their surroundings are more likely to survive. A coloration change in beetles would explain this because the color change may help them blend in with their surroundings better, thus escaping predators and having a greater chance of survival. These beetles, due to their success, will become prevalent, meaning that the other beetles will phase out because they have not adapted well to the environment.
