Blood is the fuel that keeps you going! Oxygenated blood is brought to organs and tissues via the arteries, while veins bring deoxygenated blood back to the heart to be replenished. The point is, without the respiratory system your blood would be useless.
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
Answer:
The carbon is moving into the air
Explanation:
Since the zebra is not eating, the carbon is only moving into the air and not out of the air
Answer:
Explanation:
(1) Remember that this occurred in a polylysine which consists only of L-Lys, the pKa of Lys residues might be different in polylysine as compared with the free amino acid in the solution.
The transition can also occur if more than 50% of the lysine residues need to be charged in order to ‘break’ the helix. Note that there is a 50:50 ratio of the coordinated bond of protons and dissociated forms.
(2) Other residues that are positively charged at neutral pH. They are arginine and histidine.
(3) Both arginine and histidine are more voluminous than Lys. Steric interference can prohibit the formation of an α-helices.
A. The only difference in the shown diagram is the temperature.
In setup 1, the temperature is 20 degree and in the setup 2, the temperature is 15 degree.
So, the scientists must be studying the effect of temperature in this controlled experiment, where temperature is variable.
The habitat of the lily plant is tropical, which have a mean temperature of 18 degree Celsius. So, the scientist must be studying the effect of low temperature on lily.
The possible hypothesis could be, The lily could survive in slightly lower temperature, if proper amount of light and other nutrients are available.
B. The replication of the experiment is very important to see the validity of the result obtained, it also reduces the variability in result and avoid any preset ideas.
