|
Of the seven levels of organization we discussed, which would fall under a study of gross anatomy? |
The organism, the organ system, and the organ would all be studied using gross anatomy. |
|
|
Identify the type of tissue that makes up the following: b. The lining of the larynx. c. The biceps. |
a. Nervous tissue. b. Epithelial tissue. c. Muscular tissue. |

The level of Ca2- ions in the blood must be carefully regulated. Cells in the parathyroid glands monitor the Ca2+ level. If the Ca2+ level decreases, the parathyroid glands are stimulated to start producing more PTH, a hormone. When parathyroid hormone levels are elevated, the kidneys will increase the amount of Ca2+ returned to the blood during the urine-making process. This is the result of an increase of Ca2+ in the blood. a.Is this positive or negative feedback? b. What is the control center? c. What is the effector? |
a. This is negative feedback. b. The control center is the parathyroid glands. c. The effector is the kidney. |

|
How do small polar molecules, such as water, enter a cell? |
Small molecules enter the cell through channel proteins.
|
|
|
How do larger molecules, such as carbohydrates, enter a cell? |
Large molecules enter the cell through carrier proteins. |
|
|
How do very large molecules, such as proteins, enter a cell? |
Very large molecules enter the cell through endocytosis.
|
|
|
A sodium ion (Na+) travels from inside the cell to outside the cell. HTe cell uses ATP to make this happen. Where is the concentration of sodium ions greater: Inside or outside the cell? |
The concentration of sodium ions was greater inside the cell than outside.
|
|
|
Is endocytosis an example of an active or passive process of transport? |
Endocytosis is an example of active transport. |
