Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).
Allopatric speciation, also referred to as geographic speciation, is a method of the formation of new species due to isolation of the species from one another through geographic means.
The first step in this process is geographic isolation, which means that the original population is divided into two groups due to geographical reasons such as movement of continents or formation of water bodies.
Next, the species are subjected to different selection pressures due to their different environments. Eventually, the gene pool becomes very different for the two species due to the different selection pressures and because they are not allowed to mix.
Finally, after enough time passes, speciation occurs, which means that the two populations cannot breed to form fertile offspring.
Hello,
PCR is a useful technique because it is used to amplify small segments of DNA.
Thanks,
Fruits with tiny hooks are most likely to be spread by animal hair.
Hope this helps!
Answer:
D. made an inference based on past experience and observation.
Explanation:
Observation involves careful study of a phenomenon.
Camille noticed that the leaves of her pothos plant were drooping this morning and that the leaves were not droopy yesterday as a result of her stern observation. She decided the plant needs to be watered to prevent it from dropping .
This typically suits her making an inference based on past experience and observation.
