Answer: For a eukaryotic organism to possess a plantlike characteristics shows its ability to manufacture its own food through the process of photosynthesis.
Explanation:
Protists are single- celled or unicellular organisms. They are made up of eucaryotic cells in which the cell structure is complex with a well - defined nucleus. Typical example if protists includes the following:
--> Volvox
--> Spirogyra
--> Euglena
--> Diatoms
--> chlamydomonas
Some protists are said to be plant like and are known as protophyta. Example of such includes Euglena, Spirogyra and chlamydomonas. This is because they have organelles called chloroplasts. This contains chlorophyll which enables them to make their own food through the process of photosynthesis. Photosynthesis is the process by which energy for sunlight is converted to high energy containing organic compounds such as glucose.
Answer:
The scientific method is a methodology to obtain new knowledge, which has historically characterized science, and which consists of systematic observation, measurement, experimentation, and the formulation, analysis and modification of hypotheses.
Explanation:
The main characteristics of a valid scientific method are falsifiability, and the reproducibility and repeatability of the results, corroborated by peer review. Some types of techniques or methodologies used are deduction, induction, abduction, and prediction, among others.
The scientific method encompasses the practices accepted by the scientific community as valid at the time of exposing and confirming their theories. The rules and principles of the scientific method seek to minimize the influence of the subjectivity of the scientist in his work, thus reinforcing the validity of the results, and therefore, of the knowledge obtained.

Answer:
Image result for How did dark brown skin evolve from our ancient early ancestors?
Evolution. Due to natural selection, people who lived in areas of intense sunlight developed dark skin colouration to protect against ultraviolet (UV) light, mainly to protect their body from folate depletion. Evolutionary pigmentation of the skin was caused by ultraviolet radiation of the sun.

Answer:
You eat the food and then the small intestine absorbs most of the nutrients in your food. The your circulatory system gives them to other part of your body and after chemical digestion and then defecation.
