Most amines are ________, meaning they dissolve in water and therefore cannot cross the cell membrane. The ________ hormones are
Doss [256]

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)

Which statement BEST describes how mutations are related to evolution? Question 3 options: There is not a strong relationship be
anygoal [31]
<h2>Answer:</h2>

Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.

<h2>Explanation:</h2>

Mutation assumes a significant job in evolution. A definitive wellspring of all hereditary variety is a mutation. It is significant as the initial step of development since it makes another DNA succession for specific quality, making another allele.

Recombination additionally can make another DNA succession (another allele) for a particular quality through intragenic recombination. Mutation going about as a developmental power independent from anyone else can possibly cause huge changes in allele frequencies over exceptionally significant stretches of time.

In areas of permafrost, stands of black spruce are frequently observed in the landscape, while other tree species are noticeably
Marizza181 [45]

This happens because taproot formation is impossible, so trees developed shallow root beds.

Permafrost is soil that has a temperature below 0 °C (for about two years) and forms a solid matrix which can extend to a depth of hundreds of meters. Because of this structure the permafrost prevents trees from developing deep root systems. As a consequence, the shallow root bed of trees such as black spruce, causes them to lean or even fall.
