Form classification is the classification of organisms based on their morphology, which does not necessarily reflect their biological relationships. Form classification, generally restricted to palaeontology, reflects uncertainty; the goal of science is to move "form taxa" to biological taxa whose affinity is known.
Answer:
1. Weaker
2. Continuous
Explanation:
A tumor suppressor gene codes for retinoblastoma protein (pRb). The retinoblastoma protein binds to transcription factor E2F when DNA damage is detected. The E2F bound to pRb can not stimulate expression of genes that code for proteins required during the process of DNA synthesis. The cell can not enter the S phase.
On the other hand, when the retinoblastoma protein is phosphorylated by cyclin E-CDK2, E2F transcription factor is free to stimulate the expression of genes required for DNA synthesis and the cell proceeds from G1 to S phase.
When the mutated retinoblastoma gene code for a protein that serves as phosphorylated protein, it will not be able to bind strongly with E2F and there would be continuous expression of genes required for S phase.

The correct answer is tricyclic antidepressants.
Tricyclic antidepressants (TCAs) are mainly subscribed for treating depression, however they are also commonly used to treat attention-deficit hyperactivity disorder and chronic pain. Also, TCAs are used for the treatment of enuresis, also known as bedwetting.
Benzodiazepines is a type of psychoactive drugs commonly used to treat anxiety, panic disorder, generalized anxiety disorder, insomnia, seizures and alcohol withdrawal.
Selective serotonin reuptake inhibitors is a class of antidepressants used to tread depression, obsessive-compulsice disorder, generalized anxiety disorder and eating disorders.
Monoamine oxidase inhibitors are mainly used to treat depression but also panic disorder.
The correct answer is - They supply the energy needed for living processes.
Both the carbon and the nitrogen, are gases that are crucial for the survival of the organisms on the planet. They are mostly used by the producers in the ecosystems, as they need them to manage to perform their cycles, get nutrition, and of course energy. The producers are the basis of the ecosystems, so if they do not have a healthy supply of carbon and nitrogen, the ecosystems on the whole planet will collapse. The carbon and the nitrogen later go from one organism to another as the energy is transferred, and usually end up back into the atmosphere again.
