It is located At the umbilicus
At 20 weeks' gestation, the fundus can be palpated at the
umbilicus. A fundus of 12 weeks' gestation is palpated at the symphysis pubis.
At 16 weeks' gestation, the fundus is midway between the symphysis pubis and
umbilicus. At 36 weeks' gestation, the fundus can be palpated just below the
ensiform cartilage.
The organelles would create a basic protein that could be modified to move chromatids during metaphase is the histine protien which is secreted from the RNA's.
<u>Explanation:</u>
Histone protein is the protein that is associated with the chromosome. The chromatin fibres get condensed into chromosomes on these proteins.
The chromatin fibre i.e. the DNA fibre gets to wrap itself around the histone octamer which is formed of two units of each of Histone H2A H2B H3 and H4. Then the H1 protein seals the turn and thus a chromosome is formed. These histone are produced in the S-phase of the cell cycle. This protein is transcribed into m-RNA's and then translated into protein.
*The key function of each of the two photosystems is to absorb light and convert the energy of the absorbed light into redox energy, which drives electron transport.
In PS II (the first photosystem in the sequence), P680 is oxidized (which in turn oxidizes water), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).
In PS I, the PS I primary electron acceptor is reduced (which in turn reduces other compounds that ultimately reduce NADP+ to NADPH), and P700 is oxidized (which in turn oxidizes the electron transport chain between the photosystems).
In transverse waves, the particle movement is perpendicular to the direction of wave propagation. Light and other types of electromagnetic radiation are examples of transverse waves. Some other examples of transverse waves include a ripple on a pond and a wave in a string.
