Answer:
In Manchester England in the 1840's there were factories that used coal which coated the trees. This allowed the darker moths to hide better against the trees than the lighter moths which were eaten by birds.
Explanation:
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)
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water
