Answer:
the flat horizontal lines indicate phase change
Explanation:
As the substance changes phase from solid to liquid and liquid to gas, the temperature remains contant due to latent heat energy.
Energy is being used to break the intermolecular bonds during phase change, therefore there is no change in temperature.
Answer:
The number of seeds in cups.
Explanation:
The independent variable is part of the experiment performed by the scientist, so in this case, the independent variable will be the number of seeds in a cup.
EDIT: The actual answer is the <u>number of days</u> and the <u>amount of soil</u>. I read the question wrong. My bad!
Answer:
The answer is B.
Explanation:
Leopard seals often eat other (smaller) seals. Larger leopard seals eat other seals, including the crabeater seal. Leopard seals are the only species of seal known to consume other species of seal. They have also been known to eat Antarctic fur seal and southern elephant seal pups.
A. Adult stem cells is the correct answer.
The adult stem cells consist of rare mature tissues, which are limited to differentiating into different cell types of their tissue of origin.
Answer:
B. The cell wall and vacuole function to maintain the structure of plant cells
С. Chloroplasts allow the cell to store energy, and mitochondria release energy for the cell
E. Molecules can enter the cell by passing through the cell membrane and may take part in chemical reactions within the cytoplasm
Explanation:
Homeostasis, which is key to the survival of an organism, is the ability of a living organism's cell to maintain a stable internal environment despite changes to the external environment. Cell structures/organelles interact with one another in order to maintain homeostasis as follows:
- The cell wall and vacuole function to maintain the structure of plant cells. The cell wall is responsible for the rigidity of the plant cell while the water content of the vacuoles make the cell turgid.
- Chloroplasts allow the cell to store energy in the bonds of the glucose molecules that form as a result of the photosynthesis that occurs in the CHLOROPLAST while the mitochondria release energy for the cell due to the cellular respiration process that breaks down the glucose molecules to release ATP.
- Molecules needed by the cell can enter the cell by passing through the cell membrane and may take part in chemical reactions within the cytoplasm.
