For example, a organism born and raised in a cold climate likely will exhibit phenotipic features closest associated with such climatic conditions compared than other from the same species born and raised in a temperate region. It means that genes differentially expressed in different conditions can influence organismal development, although both organisms have potential to express the same genes

2. Loss of muscle strength; breakdown of acetylcholine, a = b) neurotransmitter

3. Degeneration of nerves in the brain leading to tremors, shuffling gait, and muscle (mask-like facial expression); dopamine is deficient in the = c) brain

4. Deterioration of mental capacity (dementia) beginning in middle age; cerebral cortex atrophy, microscopic = d) neurofibrillary tangles

5. Unilateral facial = e) paralysis.

LiRa [457]

The question is in another language, so the English translation of the question is as follows:

Someone explains to me the meaning of the dual hydrophobic and hydrophilic nature of the phospholipid.

Answer:

Cell membrane are composed of a class of lipids are called Phospholipids. Phospholipds is an amphiphilic molecule made up of a hydrophilic "head" and two hydrophobic fatty acid "tails".

The two hydrophobic fatty acid "tails" are non-polar in nature and move away from water molecules. The hydrophilic "head" are polar in nature and attract towards water molecules.

This shows dual hydrophobic (two hydrophobic fatty acid "tails") and hydrophilic nature of the phospholipid.
