Answer: Transcription - A
Explanation:
This problem is talking about the lac operon and the gene expression of lac operon. If the gene is turned off, then transcription, the generation of mRNA won't occur.
Answer:
The xylem is located in the root, stem and the leaves of a plant.
The xylem contains dead cells arranged end-to-end forming continuous vessels. They have a hollow central space (lumen) through which water passes. They walls contain lignin.
The xylem carries water and minerals, up from the roots to the rest of the plant.
Pandas only blink sometimes because they are looking out for danger most of the time. Like other mammals, they have an upper and lower eyelid, so yes they do blink, but not as much as humans.
Answer:
0.04 for 6 legs starfish and 0.96 for 5 legs starfish.
Explanation:
The allele frequency for the 6 legs starfish is 0.04 whereas, the allele frequency for the 5 legs starfish is 0.96 because there is only one 6 legs starfish in the given population as compared to 5 legs starfish. The low population of 6 legs starfish is due to the presence of recessive allele while on the other hand, higher population of 5 legs starfish is due to the presence of dominant allele. The allele frequencies for both population is done by dividing the allele of interest by total number of alleles present in the population.
B is not part of the cell theory; there are many types of cells that do not have cell walls, so the statement cannot even be generally true.
