Answer:
(menstrual phase) this is the phase where the unfertilized ovum and endometrium that was formed in readiness for implantation slough off or come out due to a sudden drop in progesterone levels
(follicular phase) this is where the graafian follicle in the ovary develops. from primary follicles due to secretion of follicle stimulating hormone by the pituitary gland and matures there after due LH hormone which will also stimulate the ovary to release the ovum
(luteal phase)this is the phase after the ovum has been released where the remains of the ruptured graafian follicle undergo reorganization to form a corpus luteum/yellow body which now produces progesterone which causes thickening of endometrium in readiness for implantation
hope this helps
True, the process is called the sliding filament model of muscle contraction.
According to the sliding filament theory, muscle proteins slide past one another to produce movement during muscular contractions. The sliding filament theory postulates that during muscle contraction, the actin (thin filaments) and myosin (thick filaments) of muscle fibers glide past each other while remaining at essentially constant lengths. A protein called myosin transforms ATP (chemical energy) into mechanical energy, causing movement and push. T
his motion causes the muscles to contract and non-muscle cells, like those in the mitosis and meiosis, to move (cell division). Additionally, the actin-myosin interaction and actin polymerization are what cause a cell to move across a surface. When troponin molecules link to calcium ions in filaments, actin filaments' myosin-binding sites become visible, promoting bridge construction. ATP serves as an energy source and powers this process. Myosin molecules' heads undergo ATP hydrolysis, changing their shape and allowing them to bind to actin filaments.

<span>The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.</span>
