High School Biology Compulsory III is to analyze each option in detail

Nothing to explain, look at the good questions. It is a graph of the size of the food particles versus the population size. I can't see the food chain at all, so I can't see the relationship between predation and ** food.

C is wrong. The waveform of ethylene and propylene is not synchronized, so it is impossible to have a symbiotic relationship. D is wrong.

A pure, the images are all different, how can it be exactly the same. As for B, where there is an intersection, there is a competitive relationship, and the three are in competition with each other.

5. Selection: As can be seen from the figure, the three species have different requirements for food size, so the food resources are not exactly the same.

B: In terms of food size requirements, A and B have a lot of overlap. In other words, both of them will prey more on certain creatures with a middle and lower body size, and there is a competitive relationship.

C: It is impossible to determine whether there is a predatory relationship between A, B and C based on the size of the predation alone.

D: The reason is the same as C

6. Select the competitive relationship caused by predation, so two species co-prey on one other species, so at least 3 species, 3 populations, they can exist in the same community.

The answer is: b.

a, the three substances and food resources are partially identical;

b is correct, as you can see from the diagram, a, b, and c are all competitive because their food has the same part;

C is false, species C and A are in competition;

D is false, species B and C are in competition.

Why don't you have any money to buy a little knowledge manual? If you want to learn well, you can buy it, ask this, and print it too, but I don't know if it's all complete

1 Heredity is the continuation of DNA in germ cells (self-coined, for understanding only) DNA in memory cells cannot be expressed in germ cells. Because it is not involved in the continuation of life.

Second, there is a big mistake in your understanding. The internal and external environment is a unique noun in biology, and the specific meaning is read in the book, I will not talk nonsense.

2. Is it wrong again? Antibodies cause allergies? It's an antigen, right?

Your understanding is strange that "heredity" is between living beings, not between some kind of substance.

Both the memory cell and its corresponding antibody have a certain period of stock in the body, and the general antibody is shorter, while the memory cell is very long.

3 Do you want examples that neuromodulation is beyond the power of? I can't really remember.

Due to the characteristics of neuromodulation, it is difficult to maintain the body in a state of dynamic equilibrium like humoral regulation. (Personal understanding, not scientific opinion).

4 See the chapter "Feedback Regulation." If you want to say the reason, we can only say that this is the property of the hypothalamus and pituitary gland.

5 people think it's a bit understandable, but it's not entirely true. Unconditioned reflexes do not need to go through the central nervous system. This can only be said that there is a manager under the boss, and then there is a ...and finally the employees.

6 There are three theories, but there are many in practice.

7 I have never thought so deeply, so hard to learn so painfully.

8 The first half is the same as 7, and the last point is that I personally think that it cannot be in the form of an electrical signal. Because once the potential is resting, isn't there nothing?

9 Use your imagination: If you put a table tennis ball in a basin with water and stir it with your hands, won't the distribution of the balls change?

10 When I saw this, I smiled. Child, you must be in pain to study, right?

It's like the label of a product, but I don't know what it is.

11 There is osmotic potential energy. If you really ignore it, wouldn't it violate the conservation of energy?

12 Times are different, and in my time there was no term for "parenchyma".

I really don't know whether to laugh at you or praise you, there shouldn't be many people who are willing to think so deeply these days, right?

Memory cells are ordinary somatic cells and are not passed on to future generations. However, the ability to specifically immune, through the DNA in the germ cells, is passed on to the offspring, and the offspring individuals produce the corresponding memory cells and antibodies when they are exposed to the corresponding antigen. Allergens that can cause allergic reactions in parents often cause allergic reactions in offspring individuals as well.

3. To maintain the dynamic balance of the internal environment, neuromodulation, humoral regulation, and immune regulation are required to participate together, only neuromodulation is of course not possible, such as antidiuretic hormone, insulin and other hormones (belonging to humoral regulation) can not be replaced, and for example, when the hypothalamus regulates the thyroid gland to secrete thyroid hormone, it cannot be neuroregulated, but can only act on the pituitary gland by secreting thyrotropin-releasing hormone, and the pituitary gland then secretes thyroid-stimulating hormone to act on the thyroid gland to secrete thyroid hormone.

Oh!!! 1. B Because mice are homeothermic animals, when the temperature is low, the physiology is naturally adjusted, so that the respiration is enhanced to obtain more heat to maintain a constant temperature. Frogs are ectotherms, and when the temperature drops, it goes into hibernation and consumes less oxygen.

2. Definitely choose C!! It is the phagocytes that process the antigen. It is then presented to T cells, which recognize antigens and release lymphokines!!

4、c。。The one-sided light makes the auxin move towards the backlit side, so that the backlit side grows fast and bends towards the light!!

The road behind bc is too far away, forget b, or d, grasp it yourself, c

We've done that.

1) Decomposers, abiotic matter and energy.

2) One organism can feed on a variety of organisms.

3) Predation vs. Competition Predation.

4) Random sampling at multiple sample points, multiple measurements to find the average.

5) Producers fixed solar energy.

6) Respiration is lost in the form of heat energy.

Not exploited. Decomposer.
