Find out what is relevant to living things? not less than fifty .

There's too much of this.,You can enter "bionics" in the application there should be many.,Let me play.,But it's too much.,Hehe.。

It's too broad.

The ** that students often go to is the Lilac Garden, the Biology Pass, and the Biology Show**.

Read more about the report. You're asking too broadly.

Khan, I haven't studied much. I only know CNKI, Lilac Garden, etc.**. Because I'm not a biology department, I don't have any specific ** for you,

Go to Bio Valley, the article above is more authoritative! Now the domestic ** is not taken seriously in the world, Changpeng is mainly too many national digging stupid people plagiarize foreign articles, if it is just to write the article you said, it is estimated that Bio Valley will be able to be full of judgments and speedy accompaniment!!

Three ways of information transmission: physical information, such as beautiful sounds, bright colors, etc.; Chemical information: such as plant alkaloids, organic acids and other metabolites, animal extrasexual hormones release to attract males, etc.; Behavioral information: such as the dance of bees.

Physical information (such as sound, light, temperature, electromagnetic waves, etc.), such as plants bloom when there is sufficient light, spiders feel the vibration frequency to judge the location of the creature, chemical information (such as urine, pheromones), such as puppy peeing, insect extrasexual hormones, etc., behavioral information (such as bees dancing, peacocks opening the screen), nutritional information (organisms are concentrated in areas with more nutrients).

Mainly: physical information (such as sound), chemical information (such as urine, smell), and behavioral information (such as bees dancing in circles and waving tails).

Answer: D Analysis: The hypothalamus secretes thyrotropin-releasing hormone and acts on the pituitary gland through humoral transmission, and the thyroid-stimulating hormone secreted by the pituitary gland acts on the thyroid gland through fluid transmission, and the thyroid gland secretes thyroid hormone, and thyroid hormone can act on the hypothalamus and the pituitary potato body through feedback regulation, so the feedback regulation of thyroid hormone is Figure 4; Neurotransmitters are released from the presynaptic membrane (the previous neuron or the hand of God is like a cell) into the interstitial fluid and act on the postsynaptic membrane (the next neuron or nerve cell), as shown in Figure 2; Sex hormones are secreted by the gonads and act on cells throughout the body through body fluids, so it is shown in Figure 1.

The two pairs of alleles in the second diagram are located on two pairs of homologous chromosomes, so that the homologous chromosomes can be separated or freely combined when the non-alleles can be separated or recombined.

In the first diagram, two pairs of alleles are on the same pair of homologous chromosomes, so A cannot be combined with D, and A cannot be combined with D.

One is a a and d on a pair of homologous chromosomes, and one is a a and d on two pairs of homologous chromosomes, respectively.

Various hormones, neurotransmitters, lymphokines.

Antibodies, hormones, neurotransmitters,
