Osteoblasts
<span>Osteoblasts are
cells are responsible for the synthesis of bone formation. They are cuboidal
cells that are located along the bone surface that comprises 4-6% of the total
resident bone cells. Also, Osteoblast arise from mesenchymal stem cells (MSC)
and MSC give rise to adipocytes, myocytes, Osteoblast and other cell types.</span>
Its called a BASE
anything with a Ph of 6 & below its an acid
anything with a Ph of 7 is neutral
& everything with a Ph of 8 & above is an alkaliine
therefore all alkkalines are bases
( but not all bases are alkaline )
i hope this helped °ω°
Could be because of natural selection(favoring a particular phenotype over the rest) or maybe genetic drift or gene flow.
The right answer is A: Enzyme activity decreases at these temperatures
Temperature influences the activity of the enzymes responsible for assisting with chemical reactions in the Calvin cycle. When temperatures are low, enzyme activity is slow. As temperatures increase, the activity of the enzymes that assist in these chemical reactions also increases to a certain extent, which is the optimal response to temperature. It is at this point that the rate of photosynthesis of plants is the highest.
As the temperature continues to rise beyond this point, the enzyme activity decreases until photosynthesis stops. It is important to remember that the rate of photosynthesis in C3 plants is higher in cold conditions, whereas it is the opposite in C4 plants.
