How can Lamarck’s theory be woven in knowing our understanding of genetics

Kitty [74]3 years ago

Lamarck is best known for his Theory of Inheritance of Acquired Characteristics: If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. He said that change is made by what the organisms want or need. For example, Lamarck believed that elephants all used to have short trunks. When there was no food or water that they could reach with their short trunks, they stretched their trunks to reach the water and branches, and their offspring inherited long trunks. Lamarck also said that body parts that are not being used, such as the human appendix and little toes are gradually disappearing. Eventually, people will be born without these parts. Lamarck also believed that evolution happens according to a predetermined plan and that the results have already been decided. Lamarcks theory has been disproven and shows that acquired traits are not passed on to offspring.

Archy [21]
All isotopes of hydrogen will always contain one proton, as a change in the amount of protons will change the substance. Assuming all isotopes aren’t ions and therefore don’t have a charge, then each of these isotopes has one electron. The only difference between them is the amount of neutrons to account for the different atomic masses.

•Generally, risk factors may lead to both mental disorders and substance use disorders. Such as genetics, stress, and trauma.

•Mental disorders can lead to drug use and substance use disorders. Using drugs or alcohol to find relief (self-medication). This could lead to addiction.

•Substance use and addiction can contribute to the occurrence of a mental disorder. Causes brain changes.

What are the treatments for dual diagnosis?

Individuals with dual disorder should treat both conditions. For the treatment to be operative, there is need to abstain from alcohol or drugs. Treatments may involve behavioral therapies and medicines. Also, support groups importance for emotional and social support cannot be neglected.
