Which statement correctly describes why the phospholipids of the cell membrane arrange the way they do in a bilayer?


The nonpolar tails are repelled by water, so they position themselves in the middle of the bilayer. The polar heads are attracted to water, so they point outward.

have no membrane-bound organelles

Answers

1. The correct answer is: cell recognition protein

2. The correct answer is: The nonpolar tails are repelled by water, so they position themselves in the middle of the bilayer. The polar heads are attracted to water, so they point outward.

3. TRUE is As cell size decreases, the surface area-to-volume ratio increases.

4. The correct answer is: have no nucleus

have no membrane-bound organelles


Answer:

1. The correct answer is cell-recognition protein.  

These kinds of proteins are classified as a glycoprotein as they are the proteins with a molecule of carbohydrate associated with it. These proteins tag the cell and assist the immune system to determine them so the cells are identified and not destructed.  

2. The correct statement is the nonpolar tails are repelled by water, so they position themselves in the middle of the bilayer. The polar heads are attracted to water, so they point outward.

Water refers to a polar molecule, thus, dissolves charged molecule with which it can produce hydrogen bonds. The uncharged or nonpolar molecule seems to be water-hating and thus produces clumps when putting in water and does not get dissolved. The amphipathic molecules like phospholipids seem to produce the lipid bilayer with the polar heads from the external and getting associated with water, and the non-polar carbon chains remain sandwiched in between, that is, away from the water.  

3. As the cell increases, the surface-area-to-volume ratio increases is false, with the decrease of the cell size, the surface area to volume ratio increases will be the correct statement.  

As the cell size decreases, the volume of the cell increases is false, the correct statement is that as the cell size decreases, the volume of the cell decreases.  

As the cell size decreases, the surface-area-to-volume ratio decreases are false. The correct statement is that as the cell size decreases, the surface-area-to-volume ratio increases.  

4. The correct answers have no nucleus and have no membrane-bound organelles.  

In prokaryotes, the DNA is not enveloped by a nucleus membrane, and thus, there DNA is not separated from cytoplasm as in the case with eukaryotes. Also, they are devoid of membrane-bound organelles as they are primitive organisms.

HELP which organelle in eukaryotic cell makes proteins a ribosome b vacuole c Golgi apparatus d endoplasmic reticulum

Answers

A. ribosome

The ribosomes make proteins in the cell. Cytoplasmic granules that are rich in ribonucleic acid, or RNA, compose ribosomes. Proteins are made continuously and are responsible for the function, structure and regulation of the tissues and organs in the body.

Its membrane is the site of production of all the transmembrane proteins and lipids for most of the cell's organelles, including the ER itself, the Golgi apparatus, lysosomes, endosomes, mitochondria, peroxisomes, secretory vesicles, and the plasma membrane.

Write one paragraph comparing the memoir and the article. Compare how the writers present similar ideas to the reader. Include evidence from the text to support your comparison.  By the time my mother married my father, however, she knew all about the true nature of the dictatorship. Thousands had lost their lives in failed attempts to return the country to democracy. Family friends, whom she had assumed had dropped away of their own accord, turned out to have been disappeared. My father had been lucky. As a young man, he had narrowly escaped to Canada after the plot he had participated in as a student failed. This was to be the first of two escapes. That same year, 1937, El Generalísimo ordered the overnight slaughter of some eighteen thousand Haitians, who had come across the border to work on sugarcane plantations for slave wages. It was from my father that my mother learned why Trujillo hated blacks with such a vengeance, how he disguised his own Haitian ancestry, how he lightened his skin with makeup.–“A Genetics of Justice,” Julia Alvarez The method his soldiers used in 1937 to try to identify those who would be killed was cruelly unique. When confronting someone in the lands along the border with Haiti, they would hold up a sprig of parsley and ask what it was. If the person responded by trilling the "r" in perejil (Spanish for parsley), he would be free to go. Anyone who didn't trill the "r" was thought to be a Haitian Creole speaker—and was likely to be killed. –“Remembering to Never Forget,” Mark Memmott
