Evolution is known as continuous changes that occur to adjust organisms in their changing environment over many generations. Various theories have been proposed to illustrate the origin of life and organic evolution. The most accepted one is the theory o…

Phenotype Frequency

The majority of populations have a certain degree of variation in their genetic pools. Scientists can predict the genetic variation happening over time by measuring the amount of genetic variation in a population and these predictions assist them in gain…

Hardy Weinberg Equilibrium

The frequencies of allele and genotype were maintained constant from one generation to another due to the absence of other evolutionary forces. It is otherwise called the Hardy Weinberg principle the field of population genetics.

Textbook Question

Chapter 32, Problem 4WIO

Biologists estimate that carnivores assimilate 90% of the mass in their diet; in contrast, most herbivores assimilate only 30% to 60% of their food . How do these differences in assimilation efficiency re late to the structure of their digestive systems?

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

Patients with multiple sclerosis frequently suffer from blurred vision. Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of patients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and after the three-week period using a standard vision test. The results were analyzed and graphed (See Figure…

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?
