    It does not have a cellular structure, but it has the characteristics of life, it is stressful, it can metabolize, but it must rely on host cells, but now we still classify it as a living organism.

    In fact, scientists are still arguing that the virus is on the cusp of the storm, and I don't know if it is a living thing.

    2.Glycine NH2-CH2-COOH, alanine NH2-CH(CH3)-COOH

    Gan-Gan is NH2-CH2-Conh-CH2-Cooh Propyl-C Yes NH2-CH(CH3)-Conh-CH(CH3)-COOH Gan-C YesNH2-CH2-Conh-CH(CH3)-COOH Propyl-Gan YesNH2-CH(CH3)-Conh-CH2-Cooh Note that the last two are not the same.

    Viruses don't have a cellular structure, but they have the characteristics of life, and the three characteristics of life are irritation, metabolism, and reproduction.

    Gan Bing. Propion.

    Gangan. C-C.

    These four dipeptides.

    Because the order after ligation is different, such as glycylene and propylene glycan, only one carboxyl group and one ammonia bond are retained, which can be the carboxyl group of alanine or the carboxyl group of glycine, which is different.

    Understand? The fact that a virus can replicate is a characteristic of life. According to high school textbooks, the essential attribute of all life is metabolism, and when I do the question, I also think that viruses have metabolism.

    "In mature tissues, auxin is transported non-polar. ”

    4-D is a synthetic plant hormone with the same function as auxin 10Ecological succession refers to the sequential process by which one ecosystem type (or stage) is replaced by another over time. Ecosystems are dynamic, and in the billions of years since the birth of life on Earth, they have been constantly evolving, changing, and succession.

    **Later, a mountain forest was destroyed, and the regrowth of trees was an ecological succession. Post-earthquake reconstruction is not an ecosystem type, so it is not an ecological succession.

    11.The key to solving the problem is the small tube of D, which is the lymphatic circulation, and the tissue fluid enters the lymphatic vessels and finally joins the blood circulation.

    a. Plasma, B. Tissue fluid, C. Intracellular fluid, D. Lymphatic fluid.

    Pick D. According to the previous algorithm, 1mol of glucose decomposes to produce 38mol of oxylatp, which consumes 6mol of oxygen. 4mol of glucose sugar was accumulated, indicating the release of 24mol of oxygen. So 152 molatp can be generated.

    This question is older.

    According to the new theory, 1mol of glucose decomposes to produce 32mol of oxylatp, which consumes 6mol of oxygen.

    Proof: You can read the book that if someone has albinism (autosomal recessive) and hemophilia (X recessive inheritance) at the same time, the genotype of the offspring born to him and a woman follows the laws of heredity.

Item A: Organisms have evolved over a long period of time to form today's characteristics, and in long-term evolution, through the survival of the fittest, most of the features that have been retained are adapted to the surrounding environment. If a gene mutation occurs, it will change the characteristics that are suitable for the environment and become unsuitable for the environment, so it is said that gene mutations have more harm than benefit. >>>More

First of all, the direction of friction and motion are opposite (note!). At the beginning, use a force of 10 N to "push the cart" to make it uniform forward Indicating that the magnitude of the friction force is 10 N backward (opposite to the direction of movement of the car), and then the friction force is still backward (because the car is still moving forward) when decelerating, then the force used by the person to "pull" the car is backward, and the direction of the two forces is the same, so the resultant force is the sum of the two forces. >>>More

Biology class just teaches you what to memorize and what to learn, as long as you buy reference books and read textbooks, it is comparable to listening to lectures.

DNA is a chain of deoxyribonucleotides, and the order in which the base pairs are arranged contains genetic information; mRNA is transcribed from DNA and contains genetic information; Proteins are translated from DNA transcription mRNA; Small molecules of amino acids only form peptide chains, proteins, and contain genetic information, in the same way nucleotides only form nucleotide chains to have genetic information. Small molecules they are the basic components that make up the chain.
