Answer: 1. Lipophobic
2.Thyroid
3.lipophilic
Explanation:
Chemical messengers can be classified by their chemical characteristics including their solubility in water and their chemical structure.
Depending on their solubility in water they can be classified in two groups:
- Hydrophobic (lipophilic) - Molecules are lipid soluble and can easily cross the plasma membrane.
- Hydrophilic (lipophobic) - Molecules that are water soluble and do not readily cross the plasma membrane.
Depending on the chemical structure
Amino Acids are lipophobic.
Amines are derived from amino acids and contain an amine group (-NH2, known as the amino group). An important group of these are the catecholamines which contain a 6 carbon ring (catechol) and are derived from tyrosine. These include dopamine, norepinephrine and epinephrine. The thyroid hormone is derived from tyrosine. All except thyroid hormones are hydrophilic. The thyroid hormone is lipophilic (hidrophobic)
There could be multiple answers to this due to where the hair like fibre is. if it is on a bacteria to aid movement it is called a flagella. if it is attached to a cell, for example in the throat or oviduct, it is called a cilia
When the pressure on a sample of a dry gas is held constant, the temperature and the volume will be direct proportion?
According to Charles Darwin's theory of natural selection, only those individual are able to survive that adapt better to the changing environment and are able to reproduce. Whereas according to Lamarck, the characters that an individual gains during its lifetime are passed on to its further generations.
Natural selection is the phenomenon that states that only those individuals area able to survive in the environment that adapt better to the changing surroundings and are successfully able to reproduce. The theory was out forward by Charles Darwin.
Characters are the traits that may be phenotypically visible or present at the genetic level. These characters define an individual.
