Hey, mind putting the question in the replies so I can answer this? Thanks.
They are constantly contributing to the scientific community and
improving it. There are always new things to be discovered and they are
constantly doing just that?
<span>The student who use the hemoglobin data to conclude that mice and shrews are more closely related than mice and humans or shrew and human is quite correct. Scientists had found a way of determining the evolution histroy of animals by means of the amino acid sequence of their hemoglobin. The higher the number of related amino acids found the closer the relationship between the two organisms. There are a difference of 29 amino acid between man and mouse and a difference of 24 amino acids between human and shrew but only a difference of 5 amino acid between mouse and shrew. This shows that mouse and shrew are closer.</span>
A decomposition reaction occurs when ionic or covalent bonds are broken and elements and or ions or simpler molecules are formed.
The correct answers are:
• How soluble the hormone is in water. Depending on is it hydrophilic or hydrophobic. For example steroid hormones (derived from lipids) are hydrophobic, meaning that are insoluble in water so they must have transport protein for the blood transport.
• whether the hormone will be able to move through the cell membrane. Hormones derived from lipids are able to pass through the membrane because are able to diffuse through the lipid bilayer. Hydrophilic hormones (from amino acids) are unable to diffuse through the lipid bilayer
• whether the hormone interacts with receptors on the cell membrane.
• whether the hormone interacts with receptors inside the cell
Hormones that diffuse freely through the membrane have internal receptors. Others have cell membrane receptors.
