Answer:
The correct answer is E. The organelle that is found in both plants and animals is the Mitochondria.
Explanation:
Mitochondria are cellular organelles responsible for supplying most of the energy necessary for cellular activity (cellular respiration). They act as energy plants of the cell and synthesize ATP at the expense of metabolic fuels (glucose, fatty acids and amino acids). The mitochondria has an outer membrane permeable to ions, metabolites and many polypeptides. This is because it contains proteins that form pores called porins or VDAC (voltage-dependent anionic channel), which allow the passage of molecules up to 10 kDa of mass and an approximate diameter of 2 nm.

Sea otters tend to inhabit the shores of the pacific (sometimes rivers, ponds, or lakes), a favorite habitat is the kelp forests on the coast of California. Mother otters even tie their babies (and sometimes themselves) in kelp leaves, keeping them near and preventing floating away when diving for food. This is a clear sign of intelligence, and they classify as mammals. Otters stay in groups led by a dominant male, but sometimes females will leave with their babies, or males will depart in search of their own group to manage.

The question is incomplete. Th ecomplete question is as following:
All of the following protect the skin and mucous membranes from infection EXCEPT
A) multiple layers of cells.
B) tears.
C) saliva.
D) HCl.
E) the "ciliary escalator."
Answer: D) HCl.
Explanation:
- The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.
- Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.
- Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
- The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,
Whereas HCL helps in the digestion process.
Hence, the correct option is D.
