Answer:
Explanation:
Having elevated LDL cholesterol levels - this increases the risk for CVD as it also brings about CHD
Having reduced HDL cholesterol levels- this increases the risk of CVD as a low HDL increases omes risk of CVD at lower rates
Being a premenopausal woman - I dont think this has any effect on the risk for CVD
Being exposed to secondhand smoke -
This also increases the risk of stroke associated with CVD
- participating in exercise: this decreases the risk of CVD
Having elevated HDL cholesterol levels - this decreases ones risk of CVD as it helps to clear cholesterol from arteries delivering them back to the lover and reducing the risk for CVD
The answer is (D), because none of the other answers make sense
Answer: 1,3&4
Explanation:
The lac operon is induced by lactose in the absence of glucose, this is because when lactose is present in the medium, lactose binds to the repressor protein, one molecule on each subunit, causing a conformational change in the repressor.
The Repressor-lactose complex is in active, so the repressor does not bind to the operator site.
RNAP binds to the operator, identifies the promoter sequence and transcribe the structural genes.
RNAP can attach to the promoter site only when CAP doesn't bind the operator. In the absence of glucose in bacteria cAMP is available which combines with CAP, preventing CAP from binding the promoter site.
