Answer:
C. Malaria
Explanation:
Malaria is caused by Plasmodium parasites. The parasites are spread to people through the bites of infected female Anopheles mosquitoes, called "malaria vectors."
Out of the choices given, the way this this provides evidence for evolution is since the genetic code is the same across species, these species must have inherited it from a common ancestor. This will make the correct answer D. <span />
Answer:
The lac operon is an operon, or group of genes with a single promoter (transcribed as a single mRNA). The genes in the operon encode proteins that allow the bacteria to use lactose as an energy source. coli normally metabolise glucose, but if glucose is not available in a new environment, the lac operon can allow E. coli to metabolise lactose, the sugar found in milk using the structural genes beta-galactosidase and lactose permease. The lac operon of E. coli contains genes involved in lactose metabolism. ... It normally blocks transcription of the operon, but stops acting as a repressor when lactose is present. The lac repressor senses lactose indirectly, through its isomer allolactose.
Explanation:
The virus' DNA becomes a part of the host cell's DNA, and every time the host cell copies and divides, it also copies viral DNA. The viral DNA may remain inactive (a provirus) for a long time, but it can become active when it frees itself from the host's chromosome, which triggers the lytic cycle.
I forget which one is the virus' DNA
Question: Which describes the variable that is changed to test the prediction?
A)dependent
B)experimental
C)control
D)independent
Answer: The variable that describes the changed to test the prediction is "independent."
Explanation:
The independent variable is the factor which gets changed or can be controlled to see its effect over the experiment. Only the independent variable responds to the changes. The independent variable will be shown on the x- axis. The age and time are two different independent variable. These two factors are independent of everything else. The variable which can be easily manipulated during the experiment is called as the independent variable.
