When the phenotype ratio of the resulting offsrping is 9:3:3:1, the genotype of the plant will be ttpp. The genotype of the plant whose phenotype appeared once out of every 16 offspring the "1" in the 9:3:3:1 ratio is ttpp. So the answer in this question is ttpp.
Answer:
Negatively repressible.
Explanation:
A control which occurs through repressor is known as negative control which may be inducible or repressible.
When a small molecule named as allolactose binds this repressor it leads to allosteric repulsion which removes repressor from the operator as a result of which RNA polymerase can start transcription. Allolactose is therefore known as inducer because it induces lac operon expression.
But here, the operator is active (induced) already so there is no need to induce the operon which means that it can only be repressed so that transcription could stop. So the answer is negatively repressible operon.

I think the best medium is agar. It is a jelly-like substance that is obtained from algae, and is used to culture small organisms such as microorganisms and bacteria.

The statement above is TRUE.
Viral and bacteria STIs are usually acquired through sexual contact with an infected person. These infections have serious devastating effects on the affected and death usually result if the infection is not treated promptly. Some of these infections are still without drugs that can cure them, especially the viral STIS.
Ectoparasitic infections are those infections that are caused by tiny parasitic organisms. They are usually transmitted by close physical contact. The parasite usually affect skin or hair and typically cause itching. The effects of these infections are mild compare to that of viral and bacterial STIs.
