Sorry for the other guy. He was rude. Here's the answer:
Animals excrete CO2 by cellular respiration. Since any living things besides plants can't break down CO2, it just gets put back into the environment. I hope I helped you :)
Answer:
I believe it may be a higher surface area to volume ratio facilitates heat loss
Explanation:
Out of the options it makes the most sense being that larger animals keep heat in...
Answer:
The genes that the child inherited from the parents is the SS gene
Explanation:
The genetic composition of the haemoglobin genotype is given by two gene variants; A which is dominant and S which is recessive. As such, an individual can be AA, AS or SS. Individuals that are AA and AS do not show traits of the disease, but SS individuals have sickle cell anaemia.
From this example, since both parents have no symptoms and their child have sickle cell, their genotypes most likely were AS and AS. Let me show you how:
A S
A AA AS
S AS SS
From the cross above, there is a 1 in 4 chance that if both parents were AS, their child will be SS. Any other composition from the parents will not produce an SS offspring. Hence the genes that the child inherited from the parents is the SS gene.
Answer:
Carbon dioxide is transported in three forms. 7% is in the dissolved form in the plasma, 70% is in the form of bicarbonate ions and 20-25% as carbaminohemoglobin, HbCO2.
Explanation:
Transport as bicarbonate ions: 70% of the CO2 is converted into bicarbonate ion and transported in plasma.
Near the tissues, as the partial pressure of CO2 is high so it diffuses into the blood from the tissues. With in the RBC it reacts with water to form carbonic acid i,e. H2CO3. As carbonic acid is unstable, it immediately dissociates into H+ and HCO3- ions. Carbonic anhydrase in the enzyme present with in the RBC which takes part in these reactions. The carbonate ion formed in the RBC quickly diffuses into the plasma and is transported to the lungs in the form of sodium carbonate.
Near the alveoli, the process is reversed that is, bicarbonate ion reenter the RBC and combines with H+ ion to form carbonic acid which then quickly splits into CO2 and H2O in the presence of carbonic anhydrase enzyme. Finally CO2 is diffused from blood to lungs where partial pressure of CO2 is low.
