Answer:
C) substitutions that reduce the affinity of hemoglobin for oxygen
Explanation:
Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.
The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.
Answer:
750 to 1,250 cubic centimeters.
Explanation:
<em>Homo erectus </em>is also known as the upright man. There species were present in the Pleistocene era. Their first fossil was dated back at 1.8 million years ago.
The brain capacity of<em> Homo erectus </em>was found to be between the 750 and less than 1,250 cubic centimeters. Their species had been derived into<em> Homo heidelbergensis.</em>
Thus, the correct answer is option (D).
Answer:
All options are correct.
Explanation:
Fibers may be defined as the type of carbohydrate that cannot be digested by the body. Two main types of fiber are soluble fibers and the insoluble fibers.
Fibers play an important role in the body. Fibers manage the blood sugar level and prevent constipation. The fibers also helps in the reduction of the absorption of cholesterol in the body. Insoluble fibers prevent constipation and soluble fibers maintains blood sugar level.
Thus, all the given options are correct.
Answer:
Bacteria are highly adaptable microorganisms who have the capability of developing defense mechanisms against that which may harm them. Not least important of all, is the easiness with which some bacteria, especially pathogenic bacteria like Salmonella, or Klebsiella, develop mechanisms of resistance to antiseptics and, most importantly, antibiotics.
Antibiotics are a chemical substance that was created, and has been developed, in order to be able to combat pathogenic microorganisms, specifically bacteria. However, because today these substances are being used indiscriminately, we are now seeing a very worrying pattern of antibiotic-resistance patterns in microorganisms that used to be sensible to them. The result, we are facing strains of pathogenic bacteria, like Klebsiella pneumonia and E. Coli, that have become resistan to all types of antibiotics, from first generation, to fourth generation. And this has meant that when people acquire infection by these pathogens, the likelihood of death by them has increased because there are no agents capable of combating them.
Exposure to antibiotics has been the sole reason why these resistant strains of bacteria have emerged, especially when these antibiotics are not necessary. And feeding these substances to animals, to ensure their development and weight gain, has not made the situation any better. Now, we are instead adding also bacteria to the list that did not use to be resistant, but that are becoming so as they become adjusted to the constant exposure to antibiotics. Again, the result has been: more people infected with bacterial strains that cannot be combated with any of the existing antibiotic agents.
