The correct answer is the second option, algae. Algae is definitely not considered a kingdom. Algae is a group under the Kingdom Plantae. This organism is completely a diverse group of photosynthetic organisms that are not completely close or related to each other.
D. They come from other living things
Explanation:
The cell theory states that all living things come from preexisting cells.
It increases the temperature at which the water boils
On these images we see the low tide and the high tide.
Explanation:
On the two images we have the same place but with two contrasting views. On the picture on the left we see that the water level is higher and the boat is floating, while on the picture on the right we can see that the water level is lower and the boat is on dry land. This is actually a representation of low tide and high tide.
The high tide occurs twice in 24 hours, on roughly 12 hours. It is the process when the water level rises and comes further toward the land. The low tide also occurs twice in 24 hours, and also on every 12 hours. It is the process of retraction of the water toward the sea. These processes occur because of the gravitational pull of the Moon (primarily), and to a lesser extent of the Sun as well.
Answer:
Explanation:
Staining is done for onion cells to visualize the cytoplasm of yellow and white onions because they are not pigmented. The staining of human cheek cells with methylene blue is necessary to stain the nucleus to get clear image of it under microscope because methylene blue binds to negative charge nucleic acids
While for leaf epidermal cells smears, staining is not necessary as they are visible under light microscope without staining and they also have pigmented materials inside them such as chlorophyll chloroplast. The cork cell is a non-living and have a cell wall whose structure is visible under light microscope.
