Please help worth 95 points. Project: Algae Cultures: Directions In this report, you will be researching the different types of algae. Report on one algae from each of the three categories (blue-green, green, and green-brown). Include the following information: Name of the algae, Category if falls under, Where it is mostly found and what conditions it needs to survive, Whether it is unicellular or multicellular, Where in the food chain algae are, and what predators it may have, Research why some scientists think algae should be classified plants, and explain the debate.

1.Which organisms did you identify 2. How easy or difficult was it to find an example of each category? Which one was the hardest to find? Why? 3. Which environments were most common to find algae in? Why do you think so? 4. What part of the food chain is the alga? 5. Why is algae classified in the Protist Kingdom and not the Plant Kingdom even though they are photosynthetic? Research why scientists feel they should be classified as plants.

1) I identified the Golden-Brown Algae.

2)  It was very easy to find the category because of the solid color base and because it only had the daitoms. It did not have multiple like the Green Algae and the Blue-Green Algae.

3) In fresh, brackish or salt water. They are found both in tropical lakes and seas, and in the alpine and polar snows. They are unicellular or multicellular protist plant organisms, whose cells do not form tissues and lack flowers. They are considered the first link in the food chain in the aquatic environment. They are found in fresh, brackish or salt water. They are primary producers in the food chain, capable of producing organic substances through photosynthesis, so they use sunlight. They are found in tropical lakes and seas up to the alpine and polar snows.

4) Producer Alga is A plant and produces food for other organisms.

5) Algae (Euglena) do photosynthesis as plants do. They also move around and eat, as do animals. But they are unicellular. In order to be classified as a plant or animal, an organism has to be multicellular, made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls while algae does't have one, so it is a protozoan. Algae resemble the protozoa, so they are put into the Protist Kingdom.

Explanation:

I had the project.

answer; /// i believe that the correct answer is; ///a combination of the birth and death

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
