Among the northern Andean countries strongly involved in the illegal coca and drug trade, Columbia is now the predominant coca producer, so the answer would be option A.
Hope this helps!
They produce pockets (eggs) for fertilization and they produce the reproductive hormones, oestrogen and progesterone.
<u>Stem cell </u>research has the potential to significantly impact the development of disease-modifying treatments for Parkinson’s disease with considerable progress made in creating dopamine-progressing cells.
Explanation:
Parkinson’s disease, a neurodegenerative disease, leads to reduction of dopamine (a neurochemical messenger which carries messages involving thinking and body movements to brain) in the body because the disease will target and kill dopamine-producing nerve cells (neurons). This leads to loss of movement and thinking abilities which are activated by dopamine.
Stem cells research is done to study about the prospects of stem cells in stem cell therapy for Parkinson’s patients as a viable source of new dopamine nerve cells. Research has been involved in growing stem cells to replace or regenerate dopamine-producing nerve cells by using embryonic stem cells or induced pluripotent stem cells as a treatment modality in Parkinson’s disease.
Answer:
A phospholipid is consists of a glycerol backbone with a 2 fatty acids (either saturated or unsaturated) attached to it and a phosphate group, hence forming the head of the phospholipid molecule. I have attached a photo below for your reference.
Answer:
A chemical bond occurs as a result of electrostatic interaction between the nuclei and the electrons of the joining atoms. ... Simultaneously, a repulsion arises between the two positively charged nuclei and the same occurs with the electrons of the two negatively charged atoms.
