Which statement best defines a protist?
Helga [31]
Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb.  Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules  across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers  like photosynthetic protists  use light energy to manufacture  their own food.<span>

What did Darwin conclude about the finches on the Galapagos Islands that later supported his theory of evolution? Check all that
Ahat [919]

Answer:

The finches on Galapagos Islands had different beak

The beaks of the finches changed over time

The Galapagos finches had a common ancestor

Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common  black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.

Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.
