The laboratories have initiated Phase 1 clinical trials for the use of human pluripotent embryonic stem cells to treat paralyzed patients following spinal cord injury. The first step is to estimate the risks and tolerance of cell transplantation in a man. The fate of stem cells (multipotent or pluripotent) in the body is still poorly understood, and it is not excluded that uncontrolled cell multiplications occur, leading to the appearance of teratomas (tumor developed from pluripotent cells).

Advantages are:

* The safety of the cells also seems to be proven (in short term)

* Rats transplanted seven days after the injury had benefited from reactivation of myelinization of neurons by oligodendrocytes, attenuation of motor neuron loss and improvement of limb motor function.

The disadvantages are:

* Constraints of the ethical and religious order, it is necessary the consent and the approval of the donor and the recipient for the transplant to take place.

* The development of the technique is still new, there is a chance that side effects of the transplant appear years after the operation.

Oxytocin and cholecystokinin are transported through the bloodstream and arrive at the uterus at the same time. Why does oxytoci
9966 [12]

Answer:The uterus has receptors for oxytocin, but not for cholecystokinin.

Explanation:

Both of the hormones are released and travel via same pathway towards the  uterus. The uterus responds to oxytocin but does not responds to cholecystokinin because the uterus has no receptor for this hormone.

Cholesystokinin is secreted from gastrointestinal system and is responsible for stimulating the digestion of protein and fat.

Whereas oxytocin plays a major role in the childbirth, sexual reproduction and social bonding.

Student provides an explanation for carbon dioxide fluctuations for different seasons of the year. ( 2 points)
jeka57 [31]

Carbon dioxide fluctuations occur for different seasons of the year due to the presence of plants in an area.

<h3>Why carbon dioxide fluctuations occur for different seasons of the year?</h3>

The carbon dioxide levels in the atmosphere moves up and down every year when plants use carbondioxide gas through the process of photosynthesis and respiration. Plants take up the carbondioxide gas in the spring and summer season and release it in fall and winter season. In this modern world, the level of carbon cycle is increasing because more carbon dioxide is emitted from burning fossil fuels and other human activities.

So we can conclude that carbon dioxide fluctuations occur for different seasons of the year due to the presence of plants in an area.
