A true-breeding<span> organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits (i.e. physically expressed traits) to its offspring.</span>
<span>The correct option is A. Endomembrane system is a series of units that work together to label, package, and transport proteins and molecules. Endomembrane system are found in the endoplasmic reticulum and golgi apparatus. The major components of the endomembrane system are golgi apparatus, endoplasmic reticulum, vessicles, cell membrane and the nuclear membrane. </span>
Answer:
Absorption
Thousands of pores on the surface of the skin can absorb vitamins, acids, water and oxygen in order to provide moisture and nourishment to our skin.
Excretion
The skin is the body’s largest waste removal system. Toxins are released through the sweat glands and pores.
Secretion
The skin secretes sebum, a mixture of oils that keeps the skin soft and supple. The layer of sebum on the outermost layer of the skin is known as the acid mantle. When intact the acid mantle has a PH that ranges from 4.5-5.5. The acid mantle is acidic in nature to protect the skin from outside invasion.
Regulation
The skin regulates the body’s temperature by sweating; when water from sweat on the skin evaporates it gives off heat and cools the body. The body’s temperature increases or by shivering or getting goosebumps when the body is cold. The contraction of muscles releases energy that warms the body.
Sensation
The skin contains millions of nerve endings that transport stimuli. These nerve endings allow humans to detect sensation such as heat, cold, pain and pressure.

The correct answer is: 'the ability to transform chemical energy into mechanical energy'. The oxidation of fats and carbohydrates through chemical reactions produce adenosine triphosphate (ATP) molecules. These ATP molecules power m<span>uscles, thereby converting chemical energy to mechanical energy.</span>
