They are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, Golgi apparatus, lysosomes, etc.
Villi increases the surface area to help with absorption and digestion. Micro-villi form a brush border that vastly increases the surface area of the plasma membrane so larger amounts of nutrients can be absorbed.
Answer:
Body size: The Emperor Penguin has larger body size compared to that of the Galapagos Penguin as a structural adaptive feature for heat regulation in their different environment.
Explanation:
The emperor penguin and the Galapagos Penguin, both live in different contrasting environments. Emperor penguins are found in cold habitats while the Galapagos Penguins are found in warm habitats. Both have evolved differently by developing several unique characteristics to make them adapt well to their different environment. Regulation of heat is one of the challenges they have to deal with to survive in their habitat. In doing this, both have evolved differently in the following ways:
The Emperor penguin: The large size of the emperor penguin’s which makes them have low smaller surface area in relation to volume. This helps it to retain heat and survive extreme cold temperatures in its environment.
The Galapagos Penguin: It has a small body size with a larger surface area in relation to its volume, which enables it to lose body heat more efficiently than the Emperor Penguin.
Answer:
A) Dark moths had a survival advantage in rural Birmingham.
Explanation:
In the given graph, the data about dark moths are colored orange, and the data about light moths are colored green. We can clearly see this in the image I've attached below.
We can see that the percentage of recovered dark moths is greater in Dorset, while the percentage of recovered light moths is greater in Birmingham. This means that the dark moths had a survival advantage in Dorset, while the light moths had the advantage in Birmingham. This is why statement A is not supported by Kettlewell's data.
Answer:
IT IS BEST FOR A CELL TO HAVE A LARGE SURFACE AREA AND A SMALL VOLUME. THEREFORE, A LARGE SURFACE AREA TO VOLUME RATIO IS MORE DESIRABLE.
