Answer:Mussels

Explanation:

The mussels are the organisms found in water which have the ability to produce amino acids which helps them in sticking their body and sticking their body to other surface.

The amino acid is a rare amino acid named as dihydroxyohenylalanine or DOPA. This amino acid is unusual which provide the ability to stick on the surface.

It enables the material to be adhesive and cohesive in nature. This organism can help the chemist to give a clue on the topic of adhesive.

Nimfa-mama [501]

Answer:

100%

Explanation:

No matter how many factors are in the cross, if an 2 purebred (homozygous individuals) are crossed, (one dominant, one recessive) the dominant phenotype will always be displayed.

Imagine a cross with between two individuals true breeding for 6 traits. One shows all dominant genotypes, one shows all recessive genotypes. The only gametes those individuals can pass on will always produce heterozygotes.

AABBCCDDEEFFGG x aabbccddeeffgg

The first individual can only give ABCDEFG alleles. The second individual can only give abcdefg alleles. Therefore, all offspring will be AaBbCcDdEeFfGg, and will therefore express the dominant trait.

If one year was one foot, how long would the Cretaceous be (65 million) in miles?
Harman [31]

If one year was a foot then 65 million years will be 65 million feet. 1 mile=5280 feet so.

65 million divided by 5280= 12310.6

So your answer would be 12,310 miles.

From an evolutionary perspective, what adaptive value do mirror neurons have?
Akimi4 [234]

Mirror neurons are said to be the factors behind social imitation. Neurons are the main cell of the nervous system which is responsible for communication of organs and control of many bodily functions. In an evolutionary standpoint, mirror neurons are an advantage because humans are able to replicate and imitate skills, behaviors and practices which they find beneficial and advantageous in the wild. Among their social peers, mirror neurons help these individuals practice social inclusion through culture, values and practices for increased group cohesion and cooperation.

why would having both polar and nonpolar properties in a protective boundary be advantageous for the cell?
Reika [66]

Explanation:

The polar nature of the membrane’s surface can attract polar molecules, where they can later be transported through various mechanisms. Also, the non-polar  region of the membrane allows for the movement of small non-polar molecules across the membrane’s interior, while preventing the movement of polar molecules, thus maintaining the cell’s composition of solutes and other substances by limiting their movement.

Further explanation:

Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties i.e. they are amphiphilic. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.
