I think The second step of cellular respiration is the Kreb's cycle and it occurs in mitochondrial matrix.
First step of cellular respiration is glycolysis and it occurs in the cytoplasm of a cell.
I am not really confident about my answer.
If I am wrong please correct me. <span />
1.
a. deoxyribose sugar, phosphate, and nitrogen-containing base
b. deoxyribose sugar
c. cytosine
d. adenine, thymine, guanine. and cytosine
I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)
</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)

Answer:
The correct answer will be-False
Explanation:
Calcitonin is a hormone produced by the parafollicular cells present in the thyroid gland.
The Calcitonin plays an important role in the human body as they reduce the level of phosphate and calcium in the blood.
The calcitonin is produced by the C-cells in response to the amount of the calcium levels in the blood as a high concentration of calcium cause release of calcitonin.
Since the calcitonin is involved in the regulation of calcium of blood and not bones therefore, false is the correct answer.
