How is phospholipid bilayer arranged? and why does it arrange that way?

Biology
1 answer:
Ainat [17]3 years ago
4 0
It arranges as 2 layers of phospholipids where the hydrophilic(water-loving) heads face toward the outside and the hydrophobic(water-hating) tails are on the inside. They arrange like this to allow for selective permeability which is why this is what a cell's plasma membrane is made up of.

Where is mrna synthesized transcription or translation.
8_murik_8 [283]

Answer:the nucleus

Explanation:mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus

“Survival of the fittest” means organisms that have the most beneficial traits are more likely to survive and produce offspring.
tester [92]

Answer:

The chart shows how well each beetle with each trait were able to survive in their environments, and Mutant 1 was clearly out living the other two, because as you can see mutant 2 has only last for at least one generation, while the non-mutated one lived a little longer. This is because Mutant 1 developed the trait that made its shell darker, and thus it's easier for them to hide from predators, and they were able to successfully pass on their genes to their offspring so now they can do the same.

What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4,
12345 [234]

Hey there! :)

Answer:

The 3rd choice. a = -4, b = 5, c = -2.

Explanation:

Rearrange the quadratic equation given into the form 0 = ax² + bx + c:

0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2

The corresponding coefficients for the a, b and c values are:

a = -4

b = 5

c = -2.

Elza [17]

Answer;

-Endoplasmic reticulum

Explanation;

Molecules produced in the nucleus are transported to the cytoplasm via endoplasmic reticulum.

-Endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.

It is an interconnected network of flattened sacs or tubes encased in membranes. These membranes are continuous, joining with the outer membrane of the nuclear membrane. It works closely with the Golgi apparatus, ribosomes, mRNA, and tRNA.
