Full name of teaching material: National Unified Examination for Teachers' Qualification "Biology Knowledge and Teaching Ability" (senior high school).
Excerpt from the true question bank of senior high school about biology knowledge and teaching ability in teacher qualification examination;
1. The function of the enzyme is ().
A. Increase the total amount of products
B. Reduce the reaction rate
C, improving the energy level of reactants
Reduce the activation energy required for the reaction.
Answer d
Analytic enzyme refers to a high molecular substance with biocatalysis function. Enzymes can accelerate the reaction rate by reducing the activation energy of chemical reactions, and most enzymes can increase the reaction rate catalyzed by them by millions of times.
The distribution of Ca2+ inside and outside the cell has the characteristics of high outside and low inside, so the transport mode of Ca2+from inside to outside the cell is (
A. Free proliferation
B. Assistance in proliferation
C. Active transportation
D. Extracellular secretion
Answer c
The analysis of Ca2* secretion in cells leads to that the ion concentration in cells is lower than that in seawater. Its absorption or excretion is carried out against the concentration gradient, and its way is active transport, which requires the carrier protein on the cell membrane and consumes the energy released by cell metabolism
3 in the final product of 3RNA and DNA hydrolysis ().
A. Five-carbon sugars are the same, but the bases of thiazide are different.
B. Five-carbon sugars are the same, but purine bases are different.
C. Five-carbon sugars are different, and the bases of histidine are the same.
D. Different five-carbon sugars have the same purine base.
Answer d
The final hydrolysis products of RNA are phosphoric acid, ribose and tetra base (AUCG), and the final hydrolysis products of DNA are phosphoric acid, deoxyribose and tetra base (ATCG). It can be seen that the five-carbon sugars of RNA and DNA are different, and the purine bases are the same.
The structure that E.coli does not have is ().
A. nuclear membrane
B. ribosomes
C. cell wall
D. circular dna
Answer a
Analysis of Escherichia coli is a kind of bacteria, belonging to prokaryotes; Its cell wall is composed of peptidoglycan, which is a simple organelle containing only ribosomes, without nucleus and nuclear membrane. Nuclear membrane is a double-layer structure at the junction of nucleus and cytoplasm in eukaryotes.
5 The following substances do not belong to biological macromolecules ().
A. deoxyribonucleic acid
B. protein
C. cellulose
D. nucleotides
Answer d
Analysis of biological macromolecules is the basic substance of life, including protein, nucleic acids, hydrocarbons and so on. Nucleotide is the basic unit of ribonucleic acid and deoxyribonucleic acid, and is the precursor of nucleic acid synthesis in vivo, which does not belong to biology.
6 The following statement about chlorophyll is wrong ().
A. Both chlorophyll a and chlorophyll b contain magnesium.
B. the light absorbed by chlorophyll can be used for photosynthesis.
C. chlorophyll. Different from the absorption peak of chlorophyll b in red light region.
D Plant leaves appear green because chlorophyll can effectively absorb green light.
Answer d
The analysis of organisms with green leaves and photosynthesis depends on the fact that their cells contain pigments that can capture energy, that is, chlorophyll. Chlorophylls in chloroplasts of higher plants in Item A mainly include chlorophyll a(CssH 1203N4Mg) and chlorophyll b (CSSH 7006n; Mg) two kinds; Item B: Chlorophyll is the main pigment of plant photosynthesis; In item C, the absorption peak of chlorophyll a in red light region is 680 nm, while chlorophyll b is 650 nm.
7 The statement that population characteristics and population numbers are changing is correct ().
Sampling method can be used to estimate the population density of some animals.
B. when the population reaches K/2, the birth rate is the highest.
C. A large number of individuals of the same species will increase the K value of this population.
D. There are many young individuals, but few elderly individuals belong to the aging type.
Answer a
Sample analysis refers to randomly selecting several quadrats in the living environment of the investigated population, calculating the population density of each quadrat by counting the number of individuals in each quadrat, and taking the average population density of all quadrats as the population density of the population, so that each individual in the population has an equal opportunity to be selected when sampling.
8 In the experiment of crude DNA extraction, what can't be used as experimental material is ().
A. cauliflower
B. Vicia faba root tip
C. Fresh pig blood
D. fresh chicken blood
Answer c
Analysis In the experiment of crude DNA extraction, both animals and plants can be used as experimental materials. However, mature red blood cells of humans and mammals do not contain nuclei and DNA, so they are not suitable for extracting DNA. Therefore, fresh pig blood can not be used as the material for this extraction experiment.
A teacher studies the influence of a new teaching model on students' learning behavior. This research method belongs to ().
A. experimental method
B. Observation method
C. interview method
D. Survey methods
Answer b
Analysis and observation method refers to a method that researchers use their own senses and auxiliary tools to directly observe the studied object according to a certain research purpose, research outline or observation table, so as to obtain information.
10 when studying "the discovery process of photosynthesis", a teacher first put forward Aristotle's point of view: "Plants are made up of soil juice, that is, the substances needed for plant growth and development come entirely from soil", and then asked "Is Aristotle's point of view correct? Such a problem belongs to ().
A. Understanding the problem
B. Integrated issues
C. analyzing the problem
D. Assessment issues
Answer d
Analytical evaluation questioning means that the questions raised by teachers have obvious distinguishing characteristics, and students need to make a clear right or wrong evaluation of the questions raised by teachers. This kind of question helps teachers to understand the students' mastery of a certain question, and then provides reference for the next teaching arrangement.
1 1 Full score of a provincial biology college entrance examination 120, a classmate got 55 points, and the final score given on the report card was "B". Such an exam belongs to ().
① Paper-and-pencil test ② summative evaluation ③ standard reference test ④ norm reference test.
A.①③
B.②④
C.①②④
D.①②④
Answer d
Analysis ① The biology college entrance examination is an evaluation of the teaching effect after the teaching activities, usually in the form of a paper-and-pencil test. (2) Summative evaluation is the evaluation of the educational quality of a period and a subject. Its purpose is to make a conclusive evaluation of the quality of students' phased learning. The purpose of evaluation is to draw conclusions or score students or obtain corresponding certificates of completion. ④ The norm reference test is a measurement based on the classical test theory, and its main purpose is to compare the subjects with the norm, so as to judge the relative position of the subjects in the group. Biology college entrance examination belongs to norm reference examination.
12 students cultivate yeast, measure the population of yeast regularly, and finally draw the "S-shaped curve" of yeast population growth. What this learning activity builds is ().
