Growth, repair, reproduce
The correct answer is - 1,180 km.
North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Than divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
Answer:
Plant-like:
presence of flagella
shows the absence of cell wall, though chloroplast may be present
Animal-like:
absence of cell wall, as well as chloroplast
Fungus-like:
feeds on decaying matter
enclosed by a membrane called a pellicle
slime mold belongs in this category
Explanation:
The protists can be classified into three groups (plant-like, animal-like, fungus-like) based on the method of nutrition, movement, and mode of reproduction.
Plant-like protists have chloroplasts and trapped sunlight to form food ad energy (photosynthesis). They also have flagella used for the movement.
Example: Algae
Animal-like protists are heterotrophs that cannot make their food. They do not have chloroplast and cell wall outside the cell membrane.
Example: Protozoa
Fungus-like protists are single-cell eukaryotes that have a protective layer outside the cell membrane called pellicle. They feed on decaying organic matter.
Example: Slime mold and water mold
Leaves are green because of chlorophyll. Chlorophyll is a pigment found in the thylakoid membranes of the chloroplasts in the leaves.
Simply, plants are green because they have green chloroplasts (organelles that carry out photosynthesis).
