2. In a study of eastern red-backed salamanders, a biologist randomly placed seven 1.0m by 1.0m quadrats in a field that measured 100m by 100m. Estimate the population density and size if the biologist found 0, 1, 1, 2, 0, 1, and 3 salamanders in the seven quadrats.

C. Active transport of large molecules in and out of the cell. Requires energy.

Explanation:

endo- the formal definition is “endometrial glands and stroma existing outside the endometrial cavity”. Essentially, it is tissue that resembles the endometrium (lining of the uterus), that exists other places. Most often, it is found in the pelvic peritoneum, or the lining of our abdominal cavity.

Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.
