The<em> cell membrane</em> controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
Answer:
Sexuality exists on a continuum.
Explanation:
The American biologist, Dr. Alfred Kinsey had incorporated in the Institute for Sex Research. He worked on a series of sexuality studies during the 1940s in Indianan university.
Dr. Alfred Kinsey explained that the sexuality exists on a continuum. The person's sexual orientation generally based on the experience and response at that time.
Thus, the answer is sexuality exists on a continuum.
Answer:
3:1
Explanation:
To find out the phenotypic ratio, we need to do a Punnet Square.
We know that R and I are the dominant alleles that produce red flowers, and r and i are the recessive traits.
<u> ║R ║ r</u>
<u>I ║RI║Ir</u>
<u>i ║Ri║ir</u>
The genotype ratio would be 3 because the dominant traits are present three times (RI, Ir, and Ri) and 1 for the recessive trait since it only appears once in the Punnet Square (ir). In conclusion, the phenotypic ratio form the roses are 3:1
<span>A spider is small enough that its weight can be supported by surface tension, the relatively weak forces that hold water molecules together. </span>Water molecules "bond"<span> to other water molecules around them in all directions, so they tend to stick more strongly to their neighbors, forming a film-like layer across the surface</span>
Answer:
Adaptive radiation
Explanation:
Adaptive radiation refers to the evolution of the multiple species from one ancestral species. The force which drives the formation of new species is the change of natural environment like the availability of resources, niche, and many other related changes.
The species adapt themselves to these changes and get transformed into new species.
The formation of a variety of species of finches on the Galapagos island is an example of adaptive radiation. The species formed as a result of the food resources they received on the island.
Thus, Adaptive radiation is the correct answer.
