what are the differences between the animal and plant cells? mj fan
Answer:
cell wall
Explanation:
plant cells have a cell wall and animals do not
Answer:
the difference about animal and plants cell is A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.

How is an analogy different from a simile and a metaphor?
An analogy compares things, while similes and metaphors only describe them.
An analogy compares several different aspects of one thing to another.
An analogy uses like or as to make a direct, simple comparison.
An analogy makes a direct, simple comparison without using the words like or as.
Answer: A simile is saying something is like something else. A metaphor is often poetically saying something is something else. An analogy is saying something is like something else to make some sort of an explanatory point. You can use metaphors and similes when creating an analogy.

Which of the following is not one of the nitrogen bases that form the rungs of the ladder in DNA? a. adenine 2. cytosine 3. francine, 4. guanine
Answer:
3 francine
Explanation:
The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue). francine is not one of them
Answer:
3. francine
Explanation:
thymine (T), adenine (A), cytosine (C), and guanine (G) thymine are the rungs of the DNA ladder.
Where does the energy stored in fossil fuels come from?
sedimentary rocks are mined and processed to make it
stored solar energy in phytoplankton, zooplankton, and other organic material
the stored energy in fossils
petroleum and natural gas
Answer:
stored solar energy in phytoplankton, zooplankton, and other organic material
Explanation:
The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.
