Answer:
No, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 binds to hemoglobin and the affinity for O2 decreases, causing it to release.
Explanation:
The O2 molecule is reversibly combined with the heme portion of the hemoglobin. When the partial pressure of O2 is high, as in the case of pulmonary capillaries, for example, the binding of O2 to hemoglobin and the release of carbon dioxide are favored, this is known as the Haldane effect. If, on the contrary, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 is bound to hemoglobin and the affinity for O2 decreases, causing it to release, this is known as the effect Bohr.
<span>RNA's nucleotides are made of a ribose sugar while DNA's are made from a deoxyribose sugar. The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar.RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.<span>RNA is mainly found in a single stranded form where it loops around itself. DNA on the other hand is a double stranded helix.

Bones become weaker in a greenstick fracture
Answer:
The answer is d. 3,4,2,1,5
Explanation:
The correct sequence is:
- Antigens from a pathogen bind to antigen receptors on Lymphocytes.
- Lymphocyte specific to antigens from a pathogen become numerous.
- Lymphocytes secrete antibodies
- Pathogen is destroyed.
- Only memory cells remain.
Adaptive Immune System/Acquired Immunity:
Adaptive immune system involves the part of immune system that is contains specific and highly specialized cells to target specific pathogens. Acquired immunity involves antigen specific antibodies that bind and mark a specific pathogen. This pathogen is then cytotoxically destroyed by specific effector cells of the immune system. Acquired immunity is also characterized by the production of memory cells at the time of mass production of antigen specific antibodies. These memory cells remain long after the pathogen has been destroyed to protect against consequent attacks from the same pathogen.
