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:
Hey Lilly, so did you know that twin studies have been conducted for more than 50 years but there is still some debate in terms of how much the variation is due to genetic or environmental factors. Identical twins are good for the "Age old Question" because "Twins" have been the main method for researching the genetic and environmental sources of variation between humans for a long time because of the availability that they give.

A muscle's endurance is its capacity to contract repeatedly against a fixed resistance over an extended length of time.
Tearm endurance:
The capacity for enduring difficulty or adversity, especially the capacity for long-term stress-inducing effort or exercise, such as a marathon runner's endurance. 2: the act of enduring many sufferings or an instance of doing so. 3: persistence of the play's significance, permanency.
Types:
The types of endurance are aerobic endurance,
anaerobic endurance : Anaerobic exercise is a type of exercise that breaks down glucose in the body without using oxygen; anaerobic means "without oxygen".
speed endurance :is the ability to prolong the amount of time where a near maximal speed can be maintained.
strength endurance :Strength endurance is the specific form of strength displayed in activities which require a relatively long duration of muscle tension with minimal decrease in efficiency"

Answer:
a. True
Explanation:
Alcohol travels through body from mouth, to stomach, into circulatory system, brain, kidneys, lungs and liver.
Alcohols when consumed gets passed through the mouth in the stomach. <u>As carbohydrates, alcohol are not digested as the molecule is very small and can easily pass through stomach lining, where the alcohol passes directly into bloodstream. Once it enters bloodstream, the alcohol is quickly distributed evenly throughout body.</u>
