Answer: The correct answer to the question is option WHEN GLUCOSE LEVELS ARE LOW AND LACTOSE IS PRESENT.
Explanation: To start with,Lac operon can be simply defined as a part of the DNA that is under the part of the DNA is manipulated and controlled by the same promoter,they can be found in some prokaryotic cells giving room for regulation over excess synthesis of protein.so simply put,these specific segment of the DNA binds with the segment of the polymerase of RNA so that transcription of the mRNA from the operon genes will be achieved.
Lac operon is also known as lactose operon, it is seen in some enteric bacteria like e.coli where they play a crucial role in coding of genes for those proteins that function in moving lactose into the cystocel and digesting it to form glucose that is used for energy generation. These lac operon are are most active when glucose levels are low and lactose is present,with the low level of glucose, the lac operon can be transcribed to a high level,this is to ascertain that the bacteria only gets to activate the lac operon and can only make use of it,that is using lactose when all the preferred energy source from glucose has been exhausted.
The <span>intrusions in the rock layers would be H and J.
</span>Intrusions are formed by crystallization of magma infiltrations inside the Earth's crust. These intrusions happen as magma ascends slowly from within the Earth penetrating any space or fissure that it can find. Because this process is so slow, as pressure is released and temperature decreases, magma solidifies and crystallizes into solid intrusive rocks. They are usually the "layers" that brake through others and appear across several other layers in a different orientation than those.
Answer:
hybridization is categorized as crossing organisms that have different traits to bring together the best of each. However, this can come with some post-zygotic barriers.
Reduced hybrid viability: hybrid offspring does not survive
Reduced hybrid fertility: hybrid offspring cannot reproduce
hybrid breakdown: first generation of hybrids are viable and fertile, however, their offspring (generation 3) are sterile.
Answer: B. In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate
Explanation:
In hypoxic tissues such as new cancerous cells, the vascular system is still underdeveloped, thus oxygen supply is reduced. To meet energy need, additional glucose is needed to convert lactate (result of anaerobic glycolysis) to pyruvate which can then go into the TCA cycle to yield energy. This phenomenon is very common in muscle tissues during exercise.
The phenotypic outcome will be pink. Incomplete dominance means none of the traits are dominant, therefore they will not mask each other. As a result, they will produce a new trait. In the case of the snapdragons, red + white = pink.
Genotypic wise, all of the offspring will be heterozygous.
