Answer:
Conformation change
Explanation:
Repressor protein in the absence of lactose binds to the operator region of the lac operon and does not allow the RNA polymerase to bind to the promoter and start the transcription of lac gene.
In the presence of lactose or allolactose, the repressor protein is not able to bind to the operator region because lactose binds to the active site of repressor protein which results in a conformation change in the repressor protein.
So as the shape of the repressor protein gets changed it do not able to bind to the operon operator and the operon is expressed.
Answer:
a beetle population moved to a greener habitat.....
The skateboard's acceleration would decrease!!!!
Answer:
C
Explanation:
Gymnosperms generally refer to a group of terrestrial, seed-producing vascular plants whose means of reproduction is an exposed ovule known as a cone.
There are 6 divisions within the gymnosperms, including cycads, ginkgos, and pinus (conifers). Gymnosperms are generally non-flowering and produce needle-like leaves. Their species are usually woody or perennial shrubs/herbs
This is <u>unlike the angiosperms</u> that are usually classified into 2, including the eudicots and the monocots. The division is based on the number of cotyledons or seed leaves carried by the plants in the group during germination.
<em>The correction option here would, therefore, be C. </em>
Answer:
variegated female x green male
Explanation:
The four o'clock (<em>Mirabilis jalapa</em>) plant is a common ornamental species of <em>Mirabilis</em> (clade Angiosperms, flowering plants) whose leaf pigmentation is a well-known case of maternal inheritance. Moreover, chloroplasts are organelles that have their own genome which follows a maternal inheritance pattern in the majority of plant and animal species because they are contained in the cytoplasm (i.e., chloroplast DNA is inherited only from the mother because only the maternal cytoplasm persists after fertilization). Thus, chloroplast DNA has an inheritance pattern that challenges Mendel's Laws of inheritance (i.e., distinct from nuclear DNA). In the case of the four o'clock plant, the genes responsible for leaf color are located in the chloroplast genome and therefore these genes are transmitted from the female parent to the progeny. In this case, the leaf variegation is caused by two different types of chloroplasts that are inherited from the mother: normal green chloroplasts and defective chloroplasts (without chlorophyll pigment).
