<span>This person is protected from the disease due to a slow production of antibodies. The person already had lack of antibodies before contracting the disease, a primary immune response the moment they contracted the disease, and they can use their slow production of antibodies to combat the disease as a secondary immune response if they come in contact with it again.</span>
Answer: The last one on the bottom i'm in biology
Mutualism
Mutualism is a relationship
between organisms of two different species in which each benefits. From the
question given above, the relationship between the termites and the unicellular
organism can be described as mutualism because both organisms benefit from each
other.
Answer:
C) a sequence of nucleotides in DNA that codes for a functional product.
Explanation:
Gene -
Gene is a fixed portion present in the chromosome of the cell , which is inbuilt with the hereditary information of the cell .
Genes directs the synthesis of the proteins .
It is basically a sequence of nucleotides present in the DNA .
Hence , from the given options the correct statement for gene is ( c ) .
Answer:
The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it indicates low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.
Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb, decrease affinity and easily unloaded to muscles.
<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.
As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules binding by Hb, and easy release to respiring cells.
