Second, comprehensive questions
25.(5 points) Read the following information and answer the questions:
Information 1: Various forms of ecological agriculture are gradually popularized in rural areas of China. Jiangnan farmers invented "high efficiency"
Paddy field polyculture mode ",when transplanting, the row spacing is widened, and ducks are raised in paddy field." Duckweed, weeds, snails and pests in rice fields become the food for ducks, and duck excrement is an excellent fertilizer for rice. In this way, not only chemical fertilizers and pesticides are saved, but also a double harvest of rice and ducks is realized.
Data 2: Chinese scientists started the "Global Rice Molecular Breeding Program" and established the largest rice gene in the world.
Database, scientists study the function of each gene, and then cultivate "super rice" with high yield, disease resistance and drought resistance, which has been popularized in some parts of the country.
(1) Rice is the staple food of people, and its main nutrient, starch, is stored in rice seeds. After the human body ingests starch, it is finally digested in the small intestine and absorbed into the blood.
(2) The following is the food chain in the data 1. What do you think is correct is ▲ (fill in optional letters).
A. Rice pests → snails → ducks B. Duckweed-snail-duck
C. Weeds/rice pests/ducks D. Rice → rice pests → ducks
(3) Ordinary rice can't produce high yield, resist diseases and drought. The fundamental reason is that ▲ those who control these traits are different from "super rice".
(4) Rice somatic cells have 12 pairs of chromosomes. During the growth of rice seedlings, with the gradual increase of cell number, the number of chromosomes in each somatic cell nucleus is ▲ (fill in optional letters).
A.12 b.24c. gradually increase I). drop off
26.(5 points) In the right picture, figure A is a schematic diagram of human heart structure, figure B is a schematic diagram of capillary flow in a certain part of human body, and figure C is a schematic diagram of nephron structure (the "one" in the figure indicates the direction of blood flow). Please complete the following according to the picture:
(1) A, B, C and D in Figure A represent four chambers of the heart, so A is ▲.
(2) If ⑦ in Figure B represents alveoli, M in Figure B is directly connected with [▲ ]▲ (blood vessel) in Figure A,
The gas diffused from ⑦ to ⑦ is ▲.
(3) If ⑦ in Figure B represents histiocyte, the blood at n is ▲ blood.
(4) When blood flows through ⑧ in Figure A, the component that cannot enter ⑨ through glomerular filtration is ▲.
27.(5 points) In recent years, the low-carbon economy with "low energy consumption, low pollution and low emissions" has been highly valued by countries all over the world, and the concept of low carbon has gradually taken root in people's hearts. Shanghai World Expo 20 10 put forward the slogan of "Low-carbon Expo", which attracted worldwide attention. In recent years, Xuzhou has also issued a series of policy documents, advocating "low-carbon economy" and "low-carbon life", and striving to build Xuzhou into a low-carbon economic and ecological demonstration zone. Please answer the following questions according to the above materials:
The reason why (1) advocates the concept of "low carbon" is mainly because human beings use a lot of fossil fuels and emit a lot of greenhouse gases into the atmosphere, which breaks the balance between carbon and oxygen in nature, leading to global warming and frequent natural disasters.
(2) On the right, carbon in the atmosphere enters plants through 【 ① ▲.
In vivo, this physiological function is performed in plant cells:
(3) The figure on the right shows several ways of carbon returning to the atmosphere ▲ (fill in the serial number).
(4) The biological components of an ecosystem include producers, consumers and decomposers, among which the indispensable component is▲.
28.(5 points) Xiaoming is a junior two student. He often sees his mother put the eggshells left after cooking upside down in the flowerpot. Her mother thinks that eggshells contain nutrients that promote the growth of plants. Can eggshells really promote plant growth? Xiao Ming is a student who likes to use his head and study hard. In order to make this problem clear, he designed the following experiments to explore this problem:
1. First, select three kinds of Chlorophytum seedlings with the same development and plant them with the same volume and quality.
In the three flowerpots A, B and C (A, B are filled with washed fine sand, and C is filled with ordinary soil).
2. No eggshells are put in pot A, and equal eggshells are put in pot B and pot C. Other management conditions are the same.
Third, after a period of time, the growth state of chlorophytum has changed. Xiao Ming recorded these changes in the following table:
Plant quality before experiment /g quality/G growth after experiment
A 4 1 5 1 Plants are weak and their leaves turn yellow.
B 4 170 plants are stronger and their leaves are greener.
C 4 199 has stout plants and dark green leaves.
Please answer the following questions according to the above materials:
(1) The question raised by Xiao Ming in the experiment is ▲
(2) Comparing the changes of two pots of plants, we can draw the conclusion that:
Eggshells can promote the growth of plants. If Xiao Ming chose it before the experiment,
The development of chlorophytum seedlings is different. Can you draw the above conclusion?
▲。
(3) Please take A on the right as an example and take other data in the table as the histogram.
In the form of.
(4) After the experiment, Xiao Ming took good care of C pot of chlorophytum because he watered it too often. Zhu Sun died of rotten roots. This is mainly because of the soil
There is too much water in the water, resulting in -▲ 1 (fill in optional letters).
A. Roots absorb too much water, which leads to cell rupture. Root bacteria multiply and destroy the roots of plants.
C. too little nutrients in the soil will lead to root cell death. D there is too little oxygen in the soil, which makes the roots unable to breathe normally.
