Brown algae is the type of protist Columbus saw. Therefore, option (D) is correct.

Seaweed is a type of brown algae, which is a type of protist that belongs to the kingdom Protista. Brown algae are large, multicellular algae that grow in the ocean and are often found in shallow, warm waters. They have a complex structure and are made up of many cells that are organized into tissues and organs. Brown algae are photosynthetic, meaning they use sunlight to produce energy and nutrients, and they are an important source of food and habitat for many marine organisms.

Other types of protists include protozoa, which are single-celled, heterotrophic organisms that can move using cilia, flagella, or pseudopodia; slime molds, which are fungi-like organisms that can move and are often found in moist environments; and water molds, which are fungi-like organisms that can grow in water and can cause disease in plants and animals.

Answer:

acidity affects the rate of weathering

Explanation:

Answer:

40

Explanation:

Each quadrant measured = 2m X 2m

Length = (2+2+2) m = 6m

Width = 2m

Total area = area of (quadrant 1 + quadrant 2 + quadrant 3)

Total area = 6 * 2 = 12 m^2

Number of coral found in dive 1 = 4

Population density = 4/12 = 1/3 (0.33)

Now,

=> Population density = (Predicted population)/area

=> 1/3 = PP/120

=> PP = 120/3 = 40

So, the required answer is 40.

The predicted population of brain coral in a reef covering 120m² is ; ≈ 40

First step : Calculate the value of the default population density

Population density = population size (dive 1) / total area

                                                                = 4 / 12  = 0.33

Total area ;

∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²

∴ Total area = 4 + 4 + 4 = 12m².

Final step : Determine the value of the predicted population of brain coral

Population density = ( predicted population ) / predicted area

0.33 = ( pp ) / 120m²

∴ Predicted population ( pp ) = 0.33 * 120

                                                 = 39.6 ≈ 40 brain corals

Hence we can conclude that the predicted population of brain coral is 40

Area of the square  = 0.25m²

Unknown:

Population density  = ?

Solution:

Population density is the number of organisms per given area;

  Population density  = [tex]\frac{number of grasses}{area of quadrat}[/tex]  

 Population density  = [tex]\frac{4}{0.25}[/tex]   = 16grass/m²

The type of tissue which produces the movement is known as Muscle Tissue. The correct option is D.

Muscle tissue is made up of cells that have the unique ability to shorten or contract in order to move bodily parts. The tissue is densely cellular and rich in blood capillaries. Because the cells are long and slender, they are sometimes referred to as muscle fibers, and they are typically organized in bundles or layers surrounded by connective tissue.

Actin and myosin are muscular proteins found in muscle. Skeletal muscle tissue, smooth muscle tissue, and heart muscle tissue are the three types of muscle tissue.

Oxygen (O2)

Explanation:

This question is describing photosynthesis which uses carbon dioxide and water as reactants in the presence of sunlight to synthesize sugar (glucose) and oxygen. The general equation is as follows:

6CO2 + 6H2O ---> C6H12O6 + 6O2

According to this question, a plant takes in 6CO2 molecules and 6H2O molecules in order to build one C6H12O6 molecule. Using the balanced equation above, the extra element is OXYGEN, which still needs to be released as a gas for the equation to be balanced i.e 6O2 molecules

When the Birch(white) trees were clean and white. The white pepper moths could blend in to the tree while the black moths stood out.

This is an example of differential reproductive success. Who ever could blend in with the tree had the better genes because it made them difficult to be spotted. The other type of moth would be not so lucky, easily spotted an eaten. The better gene lead is "successful," because that moth could live longer because of its characteristics..
