Answer:
C. A mutation in the operator sequence
Explanation:
The operator sequence of the lac operon serves as the site for the binding of repressor protein. When repressor protein is bound to the operator sequence, the enzyme RNA polymerase is inhibited to carry out the process of transcription of the structural genes of the operon. Binding of allolactose to repressor does not allow it to bind to the operator sequence. This allows the expression of the lac operon in the presence of lactose sugar.
Any mutation in the operator region that disturbs the binding of the repressor to it would allow the expression of lac operon even in the absence of lactose allowing it to be expressed in a constitutive manner.
The CMBR is leftover radiation from the big bang theory.
and it support the BBT because it is the way were scientist test the big bang.
hope it help you
thank you
:)

Answer:
Solar waves with wavelengths between 160 and 400 nanometers are known as ultraviolet rays and carry higher levels of energy than sunlight. Solar waves with wavelengths between 780 and 1,500 nanometers are known as infrared rays and carry lower levels of energy than sunlight.
Answer and Explanation:
Gregor Mendel, the father of Genetics, designed different types of methodologies to study and understand how traits are inherited. Therefore, he wondered if he'd be able to predict the inheritance of a single trait and its association to a specific gene.
Through the Principle of Independent Assortment, he explained how genes segregate (or separate) in homologous chromosomes during meiosis. During this process, the alleles of different genes are sorted in gametes and inherited independently. This results in genetic diversity and recombination.
For instance, he tested green and yellow peas which were either wrinkled or smooth. <u>This principle states that the offspring could have 'mixed' traits, for example green and wrinkled, green and smooth, yellow and wrinkled, etc.</u>
Lipids, Although there is four classes of macromolecules that constitute all living matter: Carbohydrates, Lipids, Proteins, and Nucleic acids. Best answer i'd go with is, Lipids.
