How would a small, uncharged lipid move across the cell membrane?

Biology
1 answer:
ElenaW [278]3 years ago
5 0

Answer:

Through simple diffusion, down the concentration gradient.

Explanation:

The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.

Ivan

Answer:

The correct answer is D. How closely related the two species are to each other

Explanation:

Genome maps of every individual is unique. Genome map is the order of sequence of nucleotide which is present in an organism. Comparison of genome map allow the scientist to know how much closely related two organisms are.

The map of two individuals of the same species is almost the same. Similarly, the two same species have a more similar genome map than two distantly related species because they share most recent common ancestor.

For example, humans and chimpanzees are more similar than other apes so  96% of the genome are identical between them. So the right answer is D.

If it picks up or loses an electron, it becomes electrically charged and highly reactive. Such electrically charged atoms are known as ions. ... In an effort to achieve equilibrium, the atom emits particles in the form of radiation until the nucleus is stable. Such unstable atoms are said to be radioactive.

What's the purpose of the coccus
lana66690 [7]
The word “coccus” has a couple of different meanings in biology<span>, but it most commonly refers to a type of bacteria that is spherical or slightly oval in shape. In this application, the plural term used to describe entire bacterial chains or infections is </span>cocci<span>, whereas a single coccus </span>bacterium<span> is called a </span>monococcus<span>. There are many different strains and species in this broad family. Some benefit life, either by helping keep cell balance or warding off other infections, while others can be quite harmful. In most cases the shape of the bacteria is useful for classification and evolutionary purposes but doesn’t say much about how it will perform or what it does. The bacteria’s individual coding and composition more commonly dictate these things.</span>
