<u>Answer and explanation;</u></h3>
<u>Zone of resting cartilage</u> is nearest to the epiphysis and contains randomly arranged chondrocytes that do not divide rapidly.
<u>Zone of Proliferation</u> produce new cartilage through interstitial cartilage growth. Chondrocytes divide and form columns resembling stacks of plates or coins.
<u>Zone of hypertrophy.</u> The chondrocytes produced in the zone of proliferation mature and enlarge, the cells nearest the diaphysis are older and undergoing hypertrophy.
Thus, a maturation gradient exists in each column: The cells nearer the epiphysis are younger and actively proliferating, whereas the cells progressively nearer the diaphysis are older and undergoing hypertrophy.
<u>Zone of Calcification</u> is a very thin zone that contains hypertrophied chondrocytes and calcified cartilage matrix. calcified cartilage is replaced by bone.
The hypertrophied chondrocytes die, and blood vessels from the diaphysis grow into the area.
Heart disease has been widely known for being genetic, but whether it is due from the environment or genetic has yet to be established. Some heart disease symptoms are chest pain, palpitations, pressure in the chest, and discomfort in the back and jaw. Although heart disease can be deadly, there is treatments available.

The functions of luteinizing hormones are:
- It stimulate the release of an egg from the ovary
- It controls menstrual cycle
Answer:
AN hypothesis can tested through experimentation and it can also be tested through deductive methods
In a science experiment only one variable is changed the independent variable to test how this changes the dependent variable
3 a variable that is observed or measured during an experiment is called the dependent variable- d
