Answer:

Leaf fall.

Leaf fall is a seasonal phenomenon characteristic of many trees, which are therefore called deciduous. Main problem The problem that leaf fall solves is the need to safely overcome the dry period. By getting rid of leaf mass, trees stop the continuous process of evaporation from the leaf surface. Temperate trees in the northern hemisphere shed their leaves in the fall because winter is not only a cold time, but also a period when the plant's roots cannot extract moisture from the soil. Thus, leaf fall is an adaptation to surviving drought.

Another problem solved by leaf fall is the removal of harmful substances from the plant. Unlike animals, plants do not have an excretory system, but metabolic products accumulate. For example, elm leaves contain 2 times more inorganic substances at the end of October than in the spring. This happens because the plant absorbs the soil solution and evaporates clean water. How more sheet The plant evaporates water, the more mineral salts it will contain by the end of the growing season. By falling, the leaf rids the plant of substances that are unnecessary and harmful to the body.

C1. Fill in the table “Causes of leaf fall” in the columns indicated by numbers 1, 2, 3.

It is not necessary to redraw the table when completing the task. It is enough to write down the column number and the content of the missing element.

Table

problem	Cause of the problem	Why can the problem be solved by leaf fall?
It is necessary to safely overcome the dry period		The continuous process of evaporation from the surface of the sheet will stop
Removing harmful substances from the plant	Plants do not have an excretory system, but metabolic products accumulate
	The wide leaf surface of trees and shrubs accumulates large mass snow

C 2. Using the content of the text “Leaf Fall” and your knowledge, answer the following questions. What evergreen plants do you know? (name at least three representatives of this group). What adaptations allow them to maintain foliage in the fall and winter?

one correct option.

When completing tasks A1-A24, select only one correct option.

The subject “biology” plays an important role in the general education of a schoolchild and belongs to the class of natural science subjects. The main task Biology is the scientific explanation of living natural phenomena, their properties and meaning. We can say that biology studies the organization of life on different levels, starting with the molecular. In fact, biology is a whole complex of sciences that study wildlife, for example, botany, zoology, anatomy, virology - these are all areas of biology. The study of biology as a subject at school begins in the seventh grade, although students are introduced to botany already in the fifth. In ninth grade, students optionally take GIA in biology.

Requirements for the level of knowledge for passing the State Examination in Biology

To successfully pass this difficult text, you need:

know and distinguish the signs of biological objects, various living organisms, plants, animals, bacteria, as well as know the characteristics of the human body - how it works, the principles of life, behavior;
understand the essence of biological processes such as nutrition, respiration, metabolism, growth, reproduction, heredity;
be able to explain the role of biology in various fields our lives, the influence of other living organisms on humans, the relationship between humans and environment and the need to protect it, the causes of hereditary diseases, to understand what immunity is, why vitamins, microelements and hormones are needed in the human body;
be able to describe and explain the results of various biological experiments;
be able to recognize, compare and describe different biological objects: cells, tissues, organs, organ systems, living organisms, plants and animals different types, and also know their classification;
know how the consequences of human activity affect various ecosystems, be able to assess risk factors for health, both for humans and other living organisms;
be able to independently search for the necessary information using various textbooks, notes from biology lessons, reference books and biological dictionaries;
be able to use your knowledge in everyday life, provide first aid, rationally organize your work and rest, and observe preventive measures for various diseases.

How to check your knowledge level?

You can check your level of knowledge yourself using:

special online test programs that set requirements for the level and scope of the student’s knowledge;
demo test options GIA in biology which not only show the level of knowledge, but also introduce the exam format;
samples test tasks and collections of various tests.

How to independently prepare for the State Examination in Biology

In preparation for the State Examination in Biology and independent study of this subject main role theoretical knowledge plays a role. You can gain the necessary knowledge from school textbooks, biological reference books, encyclopedias, biology lesson notes, and video lessons. You need to get acquainted with the material gradually, moving from a simple topic to a more complex one; for example, you should not take on the study of human physiology without learning the structure of cells and tissues. The perfect plan for self-study biology - school curriculum, which is built in exactly this way - from simple to complex. The practical side is also very important, because studying animals or plants in person is much more interesting. If this is not possible, then various scientific films about wildlife will be useful to you. Be sure to make your personal biology lesson notes which will help you quickly repeat and consolidate the material you have covered.

Very soon, every ninth grade will take exams. They influence not only the matriculation certificate, but also whether the student enters tenth grade or college. Biology tests for the OGE are simply necessary for future doctors who plan to obtain a junior medical degree. It’s not for nothing that most schoolchildren consider biology the most difficult school subject. There are many anatomical terms as well as chemical and biological bases.

Features of the biology exam

This exam consists of two parts. The first of them contains twenty-eight tasks, of which 22 are at the basic level of difficulty. Answers to the OGE in biology in tests in this part must be in the form of a single digit, which corresponds to the number of the correct statement.

Another 6 tasks relate to increased level complexity. Among two of them, you need to choose and write down three correct answers out of six.

After this stage, they proceed to the most difficult stage, namely the second part. It contains four tasks for which you need to give not just one letter, but a detailed answer. The OGE in biology will be checked by experts who act according to the main assessment criteria.

How are assignments graded?

There is a special table that can be used to convert the number of points scored into a five-point system:

from 13 to 25 are translated into “3”;
from 26 to 36 means “4”;
over 37 – “5”.

Converting grades to points

Point conversion scale

For the first twenty-two tasks, each correct answer is worth one point. If it is completely incorrect, the result will be "0". If tasks from 23 to 27 are completed correctly, “2” points are given for each correct choice.

Task 28 can even be graded “3”. For the next four questions, the score will depend on how complete the answer is and how correctly it is done.

The maximum number of points that can be scored for the OGE tests in biology is “46”. Three hours are given to complete this work.

Where is the best place to prepare?

The well-known portal “Dunno” will allow you to go through biology buildings online.

Dunno website

Also here you can download tasks in PDF format and print them to try to cope with the OGE with a pen. This will help you lose all nerves and feel confident during the exam itself.
