Answer:

What is true of natural selection? A. Natural selection is a random process. B. Natural selection creates beneficial mutations. C. The only way to eliminate harmful mutations is through natural selection. D. Mutations occur at random; natural selection can preserve and distribute beneficial mutations.

The answer is D

Explanation:

natural selection  can simply be explained as  individuals that have specific  inheritable traits will most likely tend to adapt and survive  and as well reproduce at higher rates than others. mutation  occurs when the nucleotide sequence of an organism  changes. so natural selection can preserve and distribute beneficial mutations.

Rashid [163]

Complete question:

What is the probability of producing a child that will phenotypically resemble either one of the two parents in the following four cases? How many phenotypically different kinds of progeny could potentially result from each of the crosses?

a. Aa Bb Cc Dd  × aa bb cc dd

b. aa bb cc dd × AA BB CC DD

c. Aa Bb Cc Dd × Aa Bb Cc Dd

d. aa bb cc dd × aa bb cc dd

Answer:

a) the probability of producing a child that will phenotypically resemble either one of the two parents is 1/8.

   There will be 16 possible phenotypes among the progeny

b) the probability of producing a child that will phenotypically resemble either one of the two parents is 1.

   There will be one possible phenotype among the progeny

c) the probability of producing a child that will phenotypically resemble either one of the two parents is 81/256 = 0.316.

   There will be 16 possible phenotypes among the progeny

d) the probability of producing a child that will phenotypically resemble either one of the two parents is 1.

   There will be one possible phenotype among the progeny

How is the way a dog looks at a face similar to the way humans look at faces
GarryVolchara [31]

Answer:

Alas, scientists haven’t figured out exactly how our dogs feel about us. But a study published this week in the journal PLOS One has yielded fresh insight into how dogs see us. It adds to existing research showing that — much like humans, other primates and even goats — our canine friends use specific regions of their brain to “process” our faces.

“Our study provides evidence that human faces are truly special for dogs, as it involves particular brain activity,” study co-author Dr. Luis Concha, an associate professor at the National Autonomous University of Mexico’s Institute of Neurobiology, told The Huffington Post in an email. “To dogs, the human face is no ordinary thing.”

Liposomes consist of ________ bilayers that enclose an aqueous compartment where drugs can be contained for delivery to specific
Anna35 [415]

Answer:

Phospholipid bilayer

Explanation:

Liposomes are vesicles are spherical in shape. They consist of at least one phospholipd bilayer most especially phosphatidycholine. Liposomes are artficial vesicles similar to a membrane, because it has an hydrophilic core surrounded by a hydrophobic lipid bilayer.

Liposomes are artificial prepared and are used for the transportation of substances like drugs and nutrients between cell parts, outside of the cell and into the cell.  

In liposomal drug delivery, the liposome fuses with other internal cell membranes at the site of action and releases its liposomal content.
