Hypothalamus
When there is abnormally high internal temperature, sensors
in the Central Nervous System send signals to the hypothalamus. The hypothalamus initiates thermoregulation
by sending messages to various organs and body systems with a various
mechanisms. High temperature will set off sweating and vasodilation to cool down
the body.
Answer:
D. Mitochondria are large enough to be seen with modern light microscopy, and can occupy as much as 20% of cytoplasmic volume.
Explanation:
Mitochondria are oval shaped organelles responsible for cellular respiration.
One of their defining characteristics
is the influx of protons from the mitochondrial membrane that enables ATP synthesis.
Mitochondria are known as the power house of the cell.
Structurally, mitochondria are spherocylindrical with a length of 2 microns and a diameter of 1 micron.
The stage in mitosis or meiosis in which duplicated chromosomes line up along the equatorial plate of the spindle.
Answer:
1.292 M
Explanation:
<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>
Using the formula:
CaVa/CbVb = na/nb
where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.
In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2
Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2
Ca = 1.292 M
Hence, the concentration of H2SO4 is 1.292 M
