I'll try to explain, because I've had tubes before. In fact, I still have them.
For me, tubes were put in because of too many ear infections, and excessive water in my ear. The tube helped drain the water out. You can see A picture I have in a file. The tubes can be put I believe in the ear drum. They're put there to help drain water that has trouble getting out on its own.
Answer:
<em>fragile X syndrome </em>
Explanation:
<em>FMR1 gene mutations</em><em> trigger fragile X syndrome.</em>The gene FMR1 offers instructions on how to make a protein called FMRP.
This gene helps to control the output of other proteins and plays a part in the growth of synapses that are specific nerve cell connections.
It creates a <em>variety of developmental issues including intellectual disabilities and cognitive impairment.</em> This disease usually affects males more significantly than women.
There are three main types of rocks: sedimentary, igneous, and metamorphic that form the rock cycle. Hope this helps :)
Answer:
B) cytoplasmic streaming in hyphae
Explanation:
Fungal mycelium refers to the branched vegetative structure of the fungi which is formed by the growth of the hyphae. The hyphae contain three zones of growth: the apical, subapical and zone of vacuolation.
The hyphae grow in the apical region which forms a branched structure in which the cytoplasm continuously moves between the hyphae at the point of fusion towards the growing tip. This movement of the cytoplasm towards the growing tip is known as "cytoplasmic streaming".
This streaming of cytoplasm is responsible for the formation of a zone of vacuolation and the mycelium is formed.
Thus, Option-B is the correct answer.
The growing tip eventually gives rise to a branch. This is the beginning of the branched mycelium. Growing tips that come in contact with neighbouring hyphae often fuse with them to form a hyphal net. In such a vigorously growing system, the cytoplasm is in constant motion, streaming toward the growing tips. Eventually, the older hyphae become highly vacuolated and may be stripped of most of their cytoplasm.
In a normal human karyotype, depending on the part of mitosis the cell is in, there are either 23 or 46.
