Cell culture useful biohisby and tissue culture testing
Correct answer: Halftone
The halftone is a reprographic technique, which uses continuous imaginary tone by the use of dots, which vary in size or in spacing.
Example: The shades of gray in print are produced by breaking the image of the object into tiny dots that appear to blend into a continuous tone when viewed with a naked eye. Such a pattern of tiny dots is called a halftone.
Answer:
The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures
Explanation:
A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.
-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.
-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.
-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.
-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.
-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.
-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.
Frost is capable of damaging the flower buds and blooms of fruiting plants to the extent that the plants will not bear fruit.
Answer:
The correct answer is option d) an interaction between nature and nurture.
Explanation:
This idea is supported by the interaction between nature and nurture. This means that all our genetically acquired aspects such as genes, inherited physical characteristics, etc. work together with the environment in which we grow, the relationship we observe in our family, the people with whom we interact and the environment in we were raised.
<u>Both concepts interacting with each other </u>form what is known as a language acquisition device.
Here it is established that all <u>children are born with the ability to learn language and reproduce it through what they observe around them</u>.
Be it the way your parents speak, the friends around you and anything in the environment that can influence this aspect.
