Answer:
Convergent evolution
Explanation:
The convergent evolution is a very interesting evolutionary process that is also very helpful when ti comes to explaining how the evolution actually works. This type of evolution appears when two or more different species, be it plants or animals, live in places that are isolated from one another, but have the same or very similar living conditions. The species then evolve in a very similar manner despite them not being closely related at all, bu the response from them is the same in order to survive in the environments that provide the same conditions. If the conditions are very harsh, hot, and dry, thus a desert, then the two plants will develop the same or very similar features. They will have very hard leaves that stop the loss of water. The amount of leaves will be very low. The root systems will be disproportionately large. They will both have the ability to extract humidity from the air. The chances are also very high that they will both have thorns for protection, as well as certain amount of poison in them for the same purpose.
Starfish, or more accurately sea stars, fill a niche as predator and prey in marine ecosystems close to shore. With more than 18,000 species in the world, they range from the tropics to the Pacific Northwest and further north. They can grow larger than a foot across and can have as many as 40 arms. While sea stars are known for their ability to regrow lost arms, they have an unusual digestive system, too.
Answer:
an indicator helps us to see the equivalence point (or end point of the valuation) during a titration experiments by causing the color change.

Answer:
phototropism
Explanation:
Phototropism is the phenomenon that is causing the bean seedling to bend as shown.
Phototropism is known to be the growth of a plant or an organism in response to a light stimulus. This means that plants or organisms grow in the direction of the light. From the image shown, we will discover that the bean seedling is bending towards the direction of the sunlight.
This phenomenon usually occur in plants but it can also occur in organisms in fungi.
When the plants grow towards the direction of sunlight, it is known as positive phototropism while when the plants move away from the direction of sunlight, it is known as negative phototropism (skototropism).
