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:
When many different species live in an environment, the environment has high<em> biodiversity</em>. If the number of predators increase in an area, the immediate effect will be a<em> unstable ecosystem (</em><em>decrease in the population of prey</em>.)
Explanation:
In ecology, biodiversity can be described as the different plants and animals which live in a habitat. If a habitat has many kind of different species, then the habitat or ecosystem will have a wide biodiversity. The wider the biodiversity, the more stable an ecosystem will be.
If the number of predators will increase then the ecosystem will become unstable. There will be more competition for resources.
Answer:
Option D, a test for the presence of cells that contain DNA
Explanation:
As we know all living organisms are made up of cells and DNA is the basic genetic material that codes for protein and traits with an organism. If even a single cell with DNA is detected on the extraterrestrial planet then it will be clear that it has life on it or the environmental conditions are favorable to support life. Cells are microscopic and hence can be seen through microscope which can be installed easily on a probe.
Hence, option D is correct
Answer:
B
Explanation:
Because the childs' chances are 50% either way.
