How do diatoms and algae obtain their food?

Answers

Answer:

Explanation:

I don't know how diatoms obtain their food, but I do know how algae obtains it. Algae is a plant, that green stuff you find growing on rocks in creeks and lake shores. Plants turn sunlight, water, and carbon dioxide into sugars, which it uses for food. Most plants also obtain nutrients from soil and water using their roots, but algae doesn't have roots so it only gets food through the process I explained above, photosynthesis. I hope this has been helpful.

Answer:

Diatoms

Explanation:

They obtain food by absorbing nutrients from ocean water. Unlike many other types of phytoplankton and marine organisms, diatoms don’t have body parts that allow them to swim. They obtain food by absorbing nutrients from ocean water, which is a very competitive process. Diatoms are relatively large and at a disadvantage for food absorption due to their bodies’ reduced surface areas.

why are there mosquitos

Answers

Answer:

To balance the food chain.

Explanation:

Mosquitoes actually play a big part in the food chain.. Animals such as frogs eat them, and what if other foods that frogs eat go out(Not saying it's gonna happen, its just a what-if)? They will have to resort to the mosquitoes. And if those were gone, the frogs would go out. Then a certain number of animals maybe maybe not would have to develop a new diet due to the extinction of frogs.

Answer:

i have no clue. i hate mosquitos.

photosynthesis

Answers

Answer: Photosynthesis

The energy in glucose cannot be released by photosynthesis.

How Can the energy in glucose be released by photosynthesis?

During photosynthesis, “producers” like green plants, algae and some bacteria convert light energy from the sun into chemical energy. Photosynthesis produces chemical energy in the form of glucose, carbohydrate or sugar.

Thus, photosynthesis is the correct option.

Answers

So it is light depending recording because of it

Answer:

Light Independent Reactions

Explanation:

The stroma is the fluid-filled space of chloroplasts the thylakoids. It contains all the enzymes required for light-independent reactions of photosynthesis and is, therefore, the site of the Calvin cycle.

The Krebs cycle and glycolysis are stages of cellular respiration and occur in the mitochondria.

Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
If predators are increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If pollution is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If the amount of food available is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.

Procedure:
The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this experiment.
Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation. The control group is the group in the experiment where the factors being tested are not applied. It allows scientists to set a baseline to compare the experimental groups that do have factors applied to them.
Test variable (independent variable): Limiting factor- Food, Pollution, Predators.

Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil. Which reason best explains why root cells need to spend energy in order to transport some minerals into cells?

Answers

The question is incomplete; the complete question is;

Root cells are unable to use sunlight energy for mineral uptake.

Mineral concentration is higher in root cells than in the surrounding soil

Cell membrane pores in roots are too small for passive uptake of minerals

Cell membranes in roots lack proteins for the passage of minerals.

Answer:

Mineral concentration is higher in root cells than in the surrounding soil

Explanation:

Mineral uptake by plant roots occurs by active transport of ions into the cells of root hairs, this process requires energy.

The concentration of minerals in the soil is quite low. The root hair cells of plants possess carrier proteins that carry mineral ions and move them into the cell against existing concentration gradient. This process requires energy and is known as active transport.

With their large cannons, their fleet was able to defeat most ships and armies they came across. Beginning in 1520, Portuguese fleets probing south along the western coast of Africa. There, they discovered a new source of gold. For this reason, the southern coast of West Africa became known as the Gold Coast. The explorer Vasco da Gama sailed around the southern tip of Africa, called the Cape of Good Hope, and cut across the Indian Ocean to reach India. After people heard about de Gamas profits, many more Portuguese sailed the same route to India, setting up posts in Africa along the way.SpainEducated Europeans knew the world was round, but they had no idea of how big it was. The Spanish thought that they could find new routes to India and China by sailing west across the Atlantic Ocean. Christopher Columbus persuaded the king and queen of Spain to pay for his voyage sailing west to reach Asia. With his three ships, Columbus reached the islands of Cuba and Hispaniola (which would later become Dominican Republic and Haiti). As he traveled to most islands in the Caribbean, Columbus thought he had reached Asia. This false belief is why the Europeans called the people they found Indians they thought they were in India.Another important explorer for Spain was Ferdinand Magellan. Magellan succeeded in reaching Asia by sailing west across the Atlantic by going around the southern tip of South American and continuing west across the Pacific Ocean. Magellan reached the Philippines in Asia, where he was killed by local natives. However, one of his ships continued on to Spain, and Magellan is given credit as being the first to sail around the entire world.The Spanish and Portuguese began competing for the territories they found in the New World. Eventually they would sign a treaty, agreeing which lands each country would be allowed to take over. The new lands were given the general name America, after the Italian explorer Amerigo Vespucci. After the success of Spain and Portugal in exploring the Americas, the Dutch, the English, and the French began sending expeditions to find new places to trade in the Americas.The European explorations would change life not only for Europeans, but also for the native peoples of South America, North America, and Africans as well.7.
