<em>Full Question:</em>
<em>Which tissue is correctly paired with its primary cell type?</em>
<em>bone: fibrocyte</em>
<em>bone: osteoblast</em>
<em>connective tissue proper: chondroblast</em>
<em>cartilage: fibroblast</em>
Explanation:
<em> </em><u><em>bone: osteoblast</em></u>
<u><em></em></u>

Osteoids comprise, significant sections of the entire bone matrix, and this includes fibers of collagen which give bone its flexibility and mechanical strength this allows born to resist stretching and twisting forces.
Osteoblasts are highly specialized cells within bone which formulate new bone through the production or secretion of parts of the organic matrix; this is referred to as the osteoid and mediate the calcification (fortification with allium) of osteoid during the formation of mature bone matrix.

Answer:
The correct option is <em><u>A. Over time, due to evolution by means of natural selection, resistant weeds survived, reproduced, and passed on their herbicide resistant genes. </u></em>
Explanation:
Herbicides can be described as substances which are used to kill unwanted plants such as the weeds. Nowadays, selective herbicides are produces which are effective in killing the weed species and do not harm the crop plants.
But over time, the weeds get resistant to the herbicide. As the theory of natural selection says, 'survival of the fittest', the herbicide which are resistant are better adapted to live hence, they pass their genes to the offsprings. This results in the production of more herbicide resistant weeds.
Cell divide two time ! first is reductional and second one is equational like mitosis !
it is as meiosis 1 and meiosis 2 !!!
