Chapter 8: Section Answers It's time to put your knowledge of nephrons, neural circuits, and more to the test!

Electrical impulses gather and accumulate in which part of a neuron, in order to initiate an action potential? What is largely responsible for the negative resting membrane potential around mV in a neuron? The opening of axon membrane voltage-gated potassium channels is responsible for which part of the action potential?

AP Biology : Nervous System

In the multiple choice section of the AP Biology test, you will have 90 minutes to answer 60 multiple choice questions and 6 grid-in items. The multiple choice questions are composed of two types of questions, stand alone and data questions.

Stand alone questions are your average multiple choice question and make up a little over half of the questions in the section. Data questions are a series of questions about a single data set graphs, charts, experiment summary. Look over the strategies for stand alone and data questions and then put the strategies to work with the following practice questions. Stand Alone Question 2. Organisms that reproduce sexually exhibit zygotic, gametic, or sporic meiosis.

One way to determine the type of life cycle an organism has is by. Life cycles are characterized by the timing of meiosis and the characteristics of the diploid and haploid generations. Embryonic development, A , does not reveal either of these characteristics, nor does fertilization, C. All gametes are unicellular, ruling out D. Data Question 1. The cecum is a portion of the large intestine located near the junction of the small intestine and the large intestine.

The following table lists the diets of several vertebrates, as well as the average length of the cecum as measured in 20 individuals of that species. Based on the following information, which of the following conclusions is most plausible?

The cecum can become a vestigial structure in carnivores, since it is shorter in species B and C than in species A and D. The cecum evolved to have an important role in the digestion of protein, since it is shorter in species B and C than in species A and D.

Species A is more closely related to species D than to species B, because A and D are both herbivores. Species B and C have a common ancestor, since the cecum in species B and C is approximately the same length. The data here suggest that the cecum is four to five times longer in species that consume plant matter for their diets A and D compared to those that consume at least some meat B and C.

Of the statements listed, the only one that logically follows is A : in carnivores, the cecum becomes unnecessary, and starts to shorten. B is the opposite of what we expect; it would be logical if it played a prominent role in digesting carbohydrates. C The data on cecum length and diet are insufficient to draw conclusions about the relatedness of species, so rule out C and D.

T he following diagram shows energy transformations within a cell. Two cellular organelles are represented by the letters A and B. Answer the following questions about the various processes depicted in the diagram and about the cell in which they are occurring. If the transformation depicted in organelle B requires oxygen, what form of energy is represented by E IV?

Chemical energy being stored as glycogen. Chemical energy released by glycolysis. Question 1 Answer. The reaction occurring in organelle A is photosynthesis, as indicated by the splitting of water and fixation of CO 2.

Question 2 Answer. The reaction occurring in organelle B is cellular respiration, as indicated by the release of energy stored in the bonds of glucose. Because the question specifies that oxygen is required, the process depicted must show aerobic respiration rather than glycolysis.

Stand Alone Question 1. Answer B Life cycles are characterized by the timing of meiosis and the characteristics of the diploid and haploid generations. Answer A The data here suggest that the cecum is four to five times longer in species that consume plant matter for their diets A and D compared to those that consume at least some meat B and C. Data Question 2. Question 1 Answer C The reaction occurring in organelle A is photosynthesis, as indicated by the splitting of water and fixation of CO 2.

Question 2 Answer C The reaction occurring in organelle B is cellular respiration, as indicated by the release of energy stored in the bonds of glucose. History Long Essay Example Essay. Need Help? Outside the U. View our International Programs.

Nervous system questions

Action potentials move down myelinated axons via saltatory conduction. The tiny gaps in between myelin sheaths are referred to as nodes of Ranvier. The action potential will jump from node to node as it moves down the axon. If an axon existed without these gaps the entire length was covered in myelin , it would be unable to conduct an action potential. Which portion of a neuron receives neurotransmitters from a previous neuron, signaling the need for propagation of action potential? Neurotransmitters from presynaptic cells are received by the dendrites of postsynaptic cells. There are myriad dendrites on each neuron that then propagate this signal to the soma or cell body , allowing the signal to be passed down the axon to another neuron.

После фиаско Попрыгунчика. Четыре года назад конгресс, стремясь создать новый стандарт шифрования, поручил лучшим математикам страны, иными словами - сотрудникам АНБ, написать новый супералгоритм. Конгресс собирался принять закон, объявляющий этот новый алгоритм национальным стандартом, что должно было решить проблему несовместимости, с которой сталкивались корпорации, использующие разные алгоритмы. Конечно, просить АН Б приложить руку к совершенствованию системы общего пользования - это все равно что предложить приговоренному к смертной казни самому сколотить себе гроб. ТРАНСТЕКСТ тогда еще не был создан, и принятие стандарта лишь облегчило бы процесс шифрования и значительно затруднило АНБ выполнение его и без того нелегкой задачи. Фонд электронных границ сразу увидел в этом конфликт интересов и всячески пытался доказать, что АНБ намеренно создаст несовершенный алгоритм - такой, какой ему будет нетрудно взломать. Чтобы развеять эти опасения, конгресс объявил, что, когда алгоритм будет создан, его передадут для ознакомления лучшим математикам мира, которые должны будут оценить его качество.

 - Бринкерхофф присвистнул.  - Я и понятия не имел.  - Его глаза сузились.  - Так к чему ты клонишь.

Прикрыв рукой глаза, он выругался и встал возле собора в маленьком дворике, образованном высокой каменной стеной, западной стороной башни Гиральда и забором из кованого железа. За открытыми воротами виднелась площадь, на которой не было ни души, а за ней, вдали, - стены Санта-Круса. Беккер не мог исчезнуть, тем более так. Халохот оглядел дворик.

Но она отдавала себе отчет в том, что, если Хейла отправят домой, он сразу же заподозрит неладное, начнет обзванивать коллег-криптографов, спрашивать, что они об этом думают, В конце концов Сьюзан решила, что будет лучше, если Хейл останется. Он и так скоро уйдет.
