Answer:
An inducer (b) stimulates the synthesis of the needed enzyme.
Explanation:
A repressor is bound to the operator in the DNA chain inhibiting the synthesis of a needed enzyme. When the inducer binds to the repressor, this one change its shape and as a result, the repressor is not bound to the promoter anymore starting the synthesis of a specific enzyme.
Answer:
Anaphase I and Anaphase II
Explanation:
In anaphase I, homologous chromosomes go to opposite poles (thus the first cell was under anaphase I), whereas, anaphase II moves individual chromatids to opposite poles (thus second cell was undergoing anaphase II)
The brain code or the neural code, which is sometimes also referred as the mind code is a interpretation of the neural activity taking place in our body. It refers to the interpretation of the activity in the brain (cerebral cortex) as data structure. It represents the mental activity as a step by step data flow in the different structures from the point of generation of the impulses to the actual sensation.
In this case, the neural coding of the optical signals is given, hence, it is a type of brain code or neural code.
<u>Answer</u>: d. All of the above are true.
If an organism lives currently in a specific environment, it does not mean that it cannot spread further on due to changes. A good example are invasive species that under human influence have spread in many areas of the globe where they have had a negative impact on native ecosystems.
Our planet is a complex system with many interconnected parts. Thus, what happens in one region can affect many other regions as both air and water move globally. The same is true for locally released carbon dioxide that will result in a local increase in air temperature. However, this can change the global air currents or itself can move and accumulate in other regions.
All cells change at different times and not at same time, mitosis is a multi step continuous process. The cycle keeps on repeating the process do not end.
Mitosis is a process by which a cell divides in an identical daughter cells, During the process one cell divides and produce two identical cells. Mitosis is for growth and replacement of dead cells, Mistakes in mitosis can result in changes in the DNA and can lead into genetic disorders.
