Answer:
1. Ribosomes
2. DNA
3. Cytoplasm
4. Cell membrane
Explanation:
Prokaryotic and eukaryotic cells possess important differences but also share some similarities. The main difference between these types of cells is that <u>eukaryotes contain membrane-bound organelles and a nucleus</u>. Moreover, <u>eukaryotic cells, in contrast to prokaryotic cells, contain a cell wall and chloroplasts (in plants) and mitochondria, Golgi apparatus, amongst other differences, including the genetic material which, in prokaryotic cells, is a single and circular DNA.</u>
The similarities, on the other hand, involve, for example, the presence of ribosomes, vesicles, vacuoles, DNA, cytoplasm, and cell membrane. Although there is a significant difference in size and arrangement, we could say they share the similarity of possessing these structures.
Temperature and precipitation.
Answer:
c. Giraffes that stretch their necks more than other giraffes will have babies with longer necks.
Explanation:
Giraffes that stretch their necks will not have babies with longer necks. A trait only shows in next generation if it is genetically inherited i.e. the gametes carry the trait to the next generation.
When giraffes stretch their necks, they are modifying their actions in their life time which will have no effect on the gametes. Hence, this trait wont be passed to the next generation and babies will not have longer necks.
"Directional selection" will most likely occur.
<u>Answer:</u> Option B
<u>Explanation:</u>
Directional selection or positive selection is an organic selection mechanism in population genetics, this scrutiny is an intense phenotype is preferred over certain phenotypes, allowing the intensity of the allele to migrate over moment towards that phenotype.
For an instance directional selection are fossil statistics showing that the scale of black bears in Europe diminished throughout ice ages interglacial phases however grew at each glacial period. A further example is the scale of the beak in a finch group.
