Answer:
Decreased breathing (a) is not a symptom of ketoacidosis.
Explanation:
Ketoacidosis is a condition involving the levated production of ketones in the organism, usually as a consequence of type 1 diabetes.
The build up of ketones in the blood is mostly due to the breakdown of fatty acids by the body to acquire energy. Since ketone is an organic acid, its high levels decrease blood pH leading to several symptoms.
Frequent urination (polurya), fruity odor to breath, dehydratation and electrolyte imbalance are some of the symptoms. Decreased breathing rate is not a symptom, actually, ketoacidosis leads to rapid breathing.
Increasing the rate of breathing reduces the amount of CO₂ in the blood, which increases its pH making it less acidic.
The answer is C. large changes in allele frequencies can occur in a short time.
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
Answer:
A metabolic pathway is a system of interrelated biochemical reactions that transform a molecule or molecules of a substrate through a series of metabolic intermediates, step by step.
Explanation:
Photosynthesis is a "developing," or anabolic, pathway, which builds sugars out of smaller molecules. Cellular respiration, by comparison, breaks down sugar into smaller particles and is a pathway that is "breaking down," or catabolic. Anabolic pathway: in bigger ones, small molecules are assembled.
