allochka39001 [22]

Answer:

The correct answer is option c. "adaptive radiation".

Explanation:

The term "adaptive radiation" is used in evolutionary biology to describe a evolutionary history at which many different organisms are created as a result of a rapid diversification of an ancestral species. This phenomenon takes place as a result of changes in the environmental conditions that forces new species to adapt quickly. The scientist observations of many intermediate forms at different continents of an ancestral reptile, most strongly support the evolutionary model of adaptive radiation.

Some leaves modify into spines, how does this modification help plants survive?
barxatty [35]
Spines primarily have a protective function in plants. The spines can be sharp, and form a physical barrier against herbivores which may want to feed on the plant. Spines however also have other benefits. The spines on a jumping cactus allow segments of the cactus to stick to passing large animals or humans, thereby allowing the cactus to spread to other areas through asexual propagation. Spines are modified leaves, and spines have a much lower surface area than leaves, and therefore can reduce transpirative loss of water by the plant during harsh droughts. Some trees in alpine regions, such as pine trees, have developed spine-like leaves to prevent the accumulation of snow in the branches.

Why do humans, as one of many on this planet, have the greatest potential to impact all other species?
sdas [7]
Because our brains are the most developed out of all of the other species on this planet. Also, we require the most maintenance to survive. We can’t live in the ocean, such as a fish, shark, dolphin, etc. but we also can’t live in the forest such as bears, deer, coyotes, etc. we need to live in a stable environment when we will have enough food to survive as well to live in certain temperatures that are best suited for our kind. Hopefully that helped a little bit
