Answer: Goblet cells
There are two main areas in the lungs that secrete mucus. From the trachea to the major bronchi ciliated cells and goblet cells are present in the epithelium cells. The surface of the epithelium cells are coated by a mucus layer of viscos elastic gel which acts as a protective barrier and is mobilized by ciliary movement. Mucins are secreted by goblin cells are a major component of the mucus. Mucus is composed of water carbohydrates proteins and lipids
Attached is the image concerning the HOXD13 gene along with the regulatory and promotor regions of the gene.
The answer will be "yes; when any of the segments of deleted, the expression level dropped to less than 100% of the control."
The experiment comprises of testing the expression of the HOXD13 mRNA from the gene by deleting segments of the regulatory regions. In the event of deletion of one segment (segment C), the mRNA expression dropped to around 60% of the control. When two segments are deleted (segments B and C), the mRNA expression dropped to less then 40% of the control. When all segments are deleted, the mRNA expression was almost to 0%.
Hello!
Don't hold me on it, but I think your answer would be A, bacteria.
Enjoy.

Answer:
Enzymes are catalysts for chemical reactions in living things. Enzymes, like other catalysts, lower the activation energy and increase the rate of chemical reac- tions. ... This means that enzymes do not change the direction of a reaction— they just change the amount of time needed for equilibrium to be reached.
Explanation:
When forces on an object are balanced, the motion of the object does not change, however, this does not meet there in no motion, just no change in motion.
