The final exam for the second semester of Biology 6 is compiled to follow the curriculum content in the current textbook. Through the 6th grade test, semester 2 will help teachers build test questions according to knowledge and skills standards, helping parents test their children’s knowledge. Especially help them practice to consolidate and improve their familiarization skills with different types of exercises to get good results in the 2nd semester exam.
1. How to get high marks for 6th graders:
Have a serious attitude in learning
When determining to study in block B and specifically want to study well in biology and get high scores in the Graduation exam to be able to enter the university of your choice. Once you’ve set your goals, it’s important that you seriously define and take responsibility for your learning – not your teachers, parents, or anyone else.
Don’t miss any lessons
Each content of knowledge in the curriculum needs to be holistic. For example, if you do not understand the structure of genes, you will not understand the regulation of gene expression, if you do not understand the structure of chromosomes, you will not understand the nature of structural mutations and the number of chromosomes… So don’t miss any lessons!
Plan to study early and study regularly
Don’t wait for the water to reach your feet before jumping, it is a mistake that is killing your score because then time will create a huge invisible pressure on you, making you tense and study less effective. fruit. Plan to study early and consistently. Please absorb all the knowledge that teachers teach in class, go home to systematize and expand and deepen… please appreciate your time in class.
Practice practical exercises right after learning the theory, orient before the possible multiple choice questions about the problem you are studying.
When learning to a certain part, do the corresponding application exercises, think and predict multiple-choice questions related to the problem you are studying, which will help you a lot.
People with good study methods are those who study while protecting their health!
As mentioned in the above content, don’t “play for a long time”, then when the time is not much, “run and run” studying late until 2 am, 3 am is a bad habit and negatively affects health. your health and especially mental health! Let’s create healthy eating habits and a reasonable and scientific rest regime to stay healthy and prepare for the exam with high scores.
Never hesitate to ask others
Don’t be afraid to ask others, especially teachers and other students when asking and being answered is a good way to remember knowledge.

Part 2 Essay
Question 1:
– 5 types of food crops: rice, corn, potatoes, cassava, beans
– 5 types of industrial crops: tea, rubber, coffee, pepper, cashew nut
Verse 2:
Role:
– Together with plants in the water, when photosynthesis gives off oxygen to help the respiration of aquatic animals
– Small floating algae that are a food source for fish and many other aquatic animals
– Algae can be used as food for humans and animals
Some algae are used as fertilizers, drugs, industrial raw materials such as concealers, glues, dyes, etc.
– Algae can also be harmful: some single-celled algae reproduce too quickly, causing the phenomenon of “water bloom”, when dead, the water becomes contaminated causing fish, spirulina, and cyclospores to live in wet rice fields. can make the root of the rice plant difficult to branch
Question 3:
Reproduction form of algae:
Vegetative (division of cells or cutting of herbaceous filaments into segments ..)
– Asexual (spore formation)
Sexuality (formation and union of gametes – that is, sex cells into a zygote)
-Conjugation (combination of two vegetative cells to form a zygote)
Question 4:

* The ear consists of the outer ear, the middle ear and the inner ear The outer ear consists of the auricle (receiving sound waves) and the ear canal (directing sound waves). The middle ear consists of the tympanic membrane, the ophthalmic portal, the ear bones, and the tympanic tube + Tympanic membrane, orifice: transmit and amplify sound + The ear bone chain includes the hammer, incus, and stirrup bones that transmit sound waves + Eustachian tubes: Ensure equalization of pressure on both sides of the eardrum The inner ear consists of the semicircular canal, the vestibule (receiving information about the position and movement of the body in space) and the cochlea (receiving sound waves). |
