There are two books in high school biology in total.,The main thing is to combine the relevant knowledge points to remember it will be more effective.。。。
Of course, in the current education system, rote memorization is still the mainstream, read it a few times and memorize it a few times! When you are tired of doing mathematics, physics and chemistry, you will memorize biology, and as for biology problems, you will grasp the skills of doing problems, such as genetic problems, and calculate the probability. If you can't do it, ask the teacher again!
Seriously, biology is not a subject to earn points in the college entrance examination, but you also have to score at least 68 points.

You're impetuous now, it's not that scary, I'm also a senior in high school, I can say from the bottom of my heart that it's really not difficult, you just think you will, calm down and memorize it seriously, and then close the textbook and think about it again to see the effect. Don't worry, you can do it.

Now when I am revising, I am learning while doing the materials, that is, I can find out what I don't know and write it down while doing the questions,。。 Don't rush.

The back must be indispensable for drops, and when you are fine, let yourself have the process of cell division, the process of fertilization, etcand other contents of the book. Commonly used terms must be memorized and often on the lips.

The one upstairs, our 4 copies.
Closer to home, I'm also a junior in high school.
Creatures need to be memorized, and although there is some comprehension, most of them still have to be memorized.
But I don't know you, our college entrance examination is definitely in the book, it won't go beyond the curriculum, it's still very effective to read more knowledge points, and biology is actually the easiest subject to attack.

No, I think high school biology is quite easy, I can basically get close to a perfect score, I think it is necessary to read the textbook thoroughly, get familiar with the basics, and figure out their relationship.

3) R-point The total amount of respiration is the smallest, and the consumption of organic matter is the least.
4) As much as 1 3
5) I can't draw ......Let's talk about it: take the difference between the total amount of CO2 at each point and the oxygen consumption at the same abscissa as the new ordinate (e.g., the length obtained by ab-bc as the new ordinate), and then trace the dot line. When drawn, it resembles an inverse function, but intersects with the coordinate axes.

The selection option should remove the "optimal" and the optimal concentration of growth hormone is only one point.
Option B should be antidiuretic hormone, secreted by the hypothalamus and stored in the posterior pituitary. Acts on the renal tubular collecting ducts.
Option d should swap phagocytes and plasma cell positions. Plasma cells only have japonica rice-specific antibodies and do not have the ability to recognize antigens. Phagocytes can engulf antigens that invade the body and do not specifically recognize antigens.
-
Selection: Although the effect of auxin is twofold, there is only one peak (i.e., the best physiological effect).
B: The hypothalamus secretes "pro-xx hormone-releasing hormone" that acts on the pituitary gland
D: Immune cells that cannot recognize antigens are plasma cells, and phagocytes that cannot be specifically recognized.
-
The answer is b, the hypothalamic release hormone (RH) can increase the synthesis and secretion of the corresponding adenopituitary hormone, such as thyrotropin-releasing hormone can promote the synthesis and secretion of thyroid-stimulating hormone in the pituitary gland, and hypothalamic inhibitory hormone can inhibit the synthesis and secretion of the corresponding hormone of the adenohypophysis; Lactogen-inhibiting hormone can reduce the synthesis and secretion of prolactin in the pituitary gland, and vasopressin can increase blood pressure and promote water absorption in the renal tubules.

c Correct! The optimal concentration for plant growth is only the only determined concentration, so a is wrong. The hypothalamus releases protropin-releasing hormone, so it is wrong. The conduction of electrical currents between neurons is unidirectional C pairs. Phagocytes recognize antigens and present D-errors.
It's similar to my situation, I also dangled in my first year of high school, not only in chemistry, but also in other subjects. When I was a sophomore in high school, I used the winter and summer vacations to re-study the knowledge of the first year of high school, did a lot of questions and read many textbooks, and then made up for the knowledge that I didn't learn well, which was a painful thing, but it was very effective. Now that I'm in college, majoring in chemistry, you can communicate with me if you have any questions. >>>More
There are no creatures in the first year of high school.
The first is genetic engineering. Genetic engineering, also known as gene splicing technology and DNA recombination technology, is based on molecular genetics and modern methods of molecular biology and microbiology as a means to construct hybrid DNA molecules of different genes (DNA molecules) in vitro according to the pre-designed blueprint, and then introduce them into living cells to change the original genetic characteristics of organisms, obtain new varieties and produce new products. Genetic engineering technology provides a powerful means for the study of gene structure and function. >>>More
Physics is a very logical subject, and learning physics well is not only based on certain mathematical knowledge, but also has strong logical thinking ability. >>>More
This is a classic question.
Two pairs of alleles are involved, a and a (on a pair of autosomes), b and b (on sex chromosomes). >>>More
