techniques allow us to scrutinize the precise structure and moment-by-moment pattern of activation in the brain.

Neuroimagining  techniques  are different methods used for examine the structure of the brain(structural Imagine), and for studying the functions of the brain parts(functional Imaging),

Explanation:

Example of structural Imaging techniques are;

Computer Axial tomography.

Diffuse optical imaging

Magnetic Resonance Imagine

Examples of Functional imaging are;

Functional Magnetic resonance imaging

Positron Emission  Tomography

Cranial Ultrasound

Magnetoencephalography

The release of low energy radiations, and implants of different metals into the body which may not be effectively screened out is the major concern of these techniques.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
