Chapter 12, Problem 3CSL
Summary Introduction
To determine:
The certain type of channel which is impaired by neurotoxins.
Concept introduction:
The neurotoxin is a type of toxin which affects the nervous tissues. Neurotoxin belongs to the class of exogenous chemical that adversely affects the functioning and structure of the nervous system. It will affect the functioning of both mature and developing nervous system. This neurotoxin prevents the depolarization stage of an action potential.

Is Southern hybridization's purpose detecting specific nucleotide sequences? How so?
Use the following information to answer the question(s) below.
Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and
Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed
the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a
measure of overall body size) plotted against the percent survival of these different size classes for males and females.

24) Use the following information to answer the question below.
Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not.
They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes
the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin.
Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are
determined (see table) and used to determine the actual allele frequencies in the population.

Refer to the table above. Is this population in Hardy-Weinberg equilibrium?
A) Yes.
C) No; there are more homozygotes than expected.
B) No; there are more heterozygotes than expected.
D) It is impossible to tell.

Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply. Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.arrow_forwardWhen physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.arrow_forward
