@Arthur Morgan 100% correct!

What are the answers??????????????????? ??????????????????? ??????????????????? ??????????????????? ??????????????????? ???????????????????

Chill dude

@Apple im so sorry that WriteTeacher was so mean to u :(

If i could say one thing to writeteacher it would be "boi if u don't"
lol xd

11. To answer this question, you need to understand the concept of diffusion. Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration. This means that molecules naturally spread out or move from areas of high concentration to areas of low concentration. So, in this question, you need to choose the answer that correctly describes the movement of molecules through diffusion.

Looking at the options provided:
1. high; low; diffusion
2. low; high; diffusion
3. high; low; active transport
4. low; high; passive transport

From our understanding of diffusion, we know that molecules move from areas of higher concentration to lower concentration, making option 1 the correct answer. Therefore, the answer to question 11 is option 1.

12. The question asks for the basic units of structure and function in living things. The answer to this question is cells. Cells are the building blocks of life and are responsible for carrying out all the necessary functions of living organisms. Therefore, the answer to question 12 is cells.

13. A group of similar cells that perform a specific function in an organism is called tissue. In multicellular organisms, cells come together to form different types of tissues, each specialized for a specific function. Therefore, the answer to question 13 is tissue.

14. Nerve cells that carry response information to muscles and organs are sensory neurons. Sensory neurons transmit signals from sensory receptors to the central nervous system, allowing organisms to perceive and respond to their environment. Therefore, the answer to question 14 is sensory neurons.

15. Carbon dioxide and water are outputs of cellular respiration. During cellular respiration, cells break down glucose and other organic molecules to produce energy. Carbon dioxide is released as a waste product, and water is also produced as a byproduct of this process. Therefore, the answer to question 15 is water.

16. Energy is essential to living things because many of the chemical reactions that occur in living things require it. Cells need energy to carry out functions such as growth, metabolism, and reproduction. Without energy, cells would not be able to perform these vital processes. Therefore, the answer to question 16 is energy.

17. Based on the observation of cell walls and membrane-bound organelles, the student can conclude that the cells must be plant cells. Animal cells do not have cell walls, and bacterial cells typically do not have membrane-bound organelles. Plant cells, however, have both cell walls and membrane-bound organelles such as chloroplasts, which are involved in photosynthesis. Therefore, the answer to question 17 is C. must be plant cells.

19. Mitochondria and chloroplasts are both organelles found in eukaryotic cells, but they have different functions.

Mitochondria are responsible for producing energy in the form of ATP through a process called cellular respiration. They are often referred to as the "powerhouses" of the cell. Mitochondria are found in almost all eukaryotic cells, including both plant and animal cells.

Chloroplasts, on the other hand, are specific to plant cells and some protists. They are involved in the process of photosynthesis, where they convert sunlight, water, and carbon dioxide into glucose and oxygen.

In summary, mitochondria produce energy through cellular respiration, and chloroplasts are responsible for photosynthesis. Therefore, the main difference between mitochondria and chloroplasts is their function and their presence in different types of cells.

No one will take your test for you, but if you post what YOU THINK for each one, a science tutor might check it for you.
