Biology Quiz for (8-9 grades with answers)

7. Scientists have long assumed the existence of a connection between the brain and mental activity. But they could not answer the questions about what laws the human brain operates in, what underlies mental activity. The answer to this question was the discovery by physiologist I.M. Sechenov of the reflex basis of the brain. Choose a scientist who scientifically proved the correctness of I.M. Sechenov’s thoughts in his teaching:

A) I.P. Pavlov;

B) N.I. Pirogov;

B) K.I. Shchepin;

D) I.I. Mechnikov.

Correct answer:

A) I.P. Pavlov. It was he who experimentally proved that the basis of higher nervous activity is conditioned reflexes. Many years of work by Pavlov and his students established the most important laws of higher nervous activity.

8. The tone of the human voice largely depends on the condition of the vocal cords. The vocal cords are very elastic, they can only be compared with the best and strongest violin strings. The vocal cords of men and women are different. For men they are:

Biology quiz 9th grade with answers and questions

Quiz for 9th grade students with answers “Live clocks and barometers”

It is known that Carl Linnaeus was the first to create a “flower clock.” Now botanists all over the world can create flower clocks from plants in their area in any corner of the globe. Let's try to create our own watch. Two teams of eight students are invited. Students approach the leader. It has two dials and two sets of cards. One team places the plants shown in the pictures in the order in which they open their flowers during the day, and the second team places the cards in the order in which they close their flowers during the day. At each dial, a consultant checks (every) student's answers. If the answer is incorrect, then the correct answer must be found by team members, fans or another team, only after that the consultant can name the correct answer, then the next participant comes up, and the order of the answer is the same if his answer is incorrect.

Answers for the first team. (Flowers open.) At 3.00 am - salsify. At 4.00 am - rosehip. At 5.00 am - poppy. At 6.00 am - dandelion. At 7.00 am - potatoes, water lily. At 8.00 am - hawk. At 9.00 am - marigolds (calendula). At 10.00 am - norichnik. Answers for the second team. (The flowers are closing.) At 10.00 - chicory.
At 11.00 o'clock - sow thistle. At 13.00 - field carnation. At 14.00 hours - poppy. At 15.00 - marigolds. At 16.00 o'clock - Len. At 17.00 o'clock - hawk. At 18.00 o'clock - sorrel. At 19.00 - rosehip. Quiz “Plants and animals - predictors”

The quiz is conducted in addition to the previous one.
The questions are answered by a representative of the team that finds the answer first; if the answer is incorrect, then the turn moves on to the next team. 1. What houseplant can predict the weather? (Monstera begins to release droplets of moisture a day before bad weather.) 2. Which plants lower their leaves at sunset and open them at sunrise? (Heliotrope, mimosa.) 3. What animals have an internal clock? (Bees, birds.) 4. How do swallows predict the weather? (Before the rain, swallows fly low above the ground, as insects also fly down.) 5. How does a water lily predict rain and tell the time? (It closes its flowers before rain and in the evening.) 6. This weed is nicknamed “barometer”. If he hasn’t opened the flowers before nine in the morning, then expect rain. It is also a favorite food of songbirds. Name this weed. (Woodlouse.) 7. In an aquarium you can have animals that predict the weather. In good weather they lie or swim leisurely, but they scurry restlessly in front of the wind, and before a thunderstorm they stick to the glass and wriggle convulsively. What kind of animals are these? (False horse leeches.) 8. How can lilac, jasmine, dandelion and chestnut predict the weather? (Lilac and jasmine smell strongly, dandelion does not open its flowers, chestnut leaves have sticky juice on their leaves a day before rain.) 9. Where is the biological clock of a cockroach? (Subpharyngeal ganglion.) 10. What marine animal predicts the approach of a storm 10-15 hours in advance? Why? (Jellyfish, it perceives infrasounds with the help of an “ear” - a tiny ball on a stalk in which tiny pebbles float. They rub against the nerve receptors in the walls of the ball, and the jellyfish hears the roar of an approaching storm, so all jellyfish go to the depths.) 11. What are they? Do the animals in the aquarium tell the observer about the high and low tide times in that area? (These are oysters; during high tide they open their valves wide.) 12. What fish can be called living barometers? (The fish rushes around the aquarium. The loach comes to the surface within 24 hours before the rain, the catfish lives at the bottom and emerges before a thunderstorm or bad weather. The bleak fish jumps out of the water after insects before the rain.) 13. Which bird starts the day and announces the cold? (Rooster) 14. How do sparrows predict frost? (Sparrows carry down and feathers under the roofs before frost.) 15. How do you know at sea that there will be calm? (In calm weather, birds fly out early and move far from the coast. This means 6-12 hours of calm.) 16. For what diseases does a person feel an imminent change in the weather? (With rheumatism, osteochondrosis, and blood pressure disorders, a person suffers from pain before bad weather, as atmospheric pressure decreases.) 17. Which part of the brain acts like a thermostat? (This is the hypothalamus; it transmits information to the pituitary gland, which sends an alarm signal to the general gland system.) 18. How have people in Japan learned about an earthquake for a long time? (Small fish in aquariums begin to rush about within a few hours.) 19. Is it possible to determine the air temperature by the chirping of a cricket? (Yes. The number of sounds in fourteen seconds plus forty is equal to the air temperature in Fahrenheit.) Presenter . So, the jury tallies the points, and we will summarize what we have learned. The famous English doctor Edward Jenner described the approach of rain in a very original way. The lights sparkled into the night, the fireflies lit up the ravine, the mercury fell in the barometer, and now the wind begins to blow. It’s as if the distant forest has become closer, It’s as if the vault of heaven has become lower, The clouds are pressed to the ground, And the cricket’s song hurts the ears. She is echoed by the sharp cry of a thrush, The water is clearer than ever, The fish is busy playing - Grabbing flies above the water. A spider peeked out of the web, suddenly pulled me towards the sofa, and my dog ​​stopped gnawing on the callus, waved his tail and went to sleep. Obedient to the wind, the dust of the roads has curled up into a spinning ball. Smoke settles on the slopes of the roofs, The Shepherd is tormented by foreboding. Evil flies are biting the cattle, The swallow is flying lower and lower, The frog has changed color - She is wearing a brown jacket, And the toad crawled out into the grass, The pig is worried in the barn. It’s fresh, even though it’s a June day, Touch it - the old stump is wet, The rooks have descended from the heights, As if struck by a bullet. The Kuroslep closed his eyes, Old Betty’s nerves began to ache, the closet crackled slightly, and there was a smell of the dampness of the ditches. A cat is warming up by the fireplace, rubbing his whiskers with his fluffy paw, the pre-sunset distance is pale, the moon is hiding behind the clouds. Yes, it will rain! It's time to come to terms with the fact that the picnic will not take place...
