The lymphatic capillary is called as lacteal
Answer:
(b)- zone of hypertrophy
Explanation:
Hypertrophic cells synthesize alkaline phosphatase by calcifying the surrounding area; prevent the diffusion of substances, this causes chondrocyte death; therefore, the matrix degrades and the lagoons converge, then the blood vessels proliferate in the collarete to vascularize the cavity. The primitive periodic cells migrate to the vascular borders to become osteoprogenitor cells which are attached to the cartilaginous spicules leaving the degradation of the calcified cartilage, then they become osteoblasts. The combination of cartilage and bone matrix forms a mixed spicule.
Endochondral bone growth begins in the second trimester of fetal life and goes to adulthood, in it there is presence of epiphyseal cartilage.
The epiphyseal cartilage has several areas including:
<u>Hypertrophy zone</u>: it is composed of large chondrocytes that accumulate glycogen. The matrix is compressed between the hypertrophied cartilaginous columns.
Answer:
As per correct scientific methodolgy, the first step that scientist needs to take is to formulate a hypothesis. Because he already has went through first two steps of scientific method, 1: Observation. 2: Question. So he should proceed with formulating a hypothesis.
A hypothesis is basically a preposition which scientists formulates based on the incomplete information he has. For example: In this case, the scientist can assume that marsh grass, <em>Spartina bakeri,</em> grows taller on east side than on west side because east side contain more nutrient enriched marshes.
This is not a fact but just a preposition that he will prove or disapprove when he will conduct the whole experiment and find the facts.
So a this stage he needs to formulate a hypothesis based on little knowledge he has.
Hope it helps!
