Movement of molecules across the cell membrane occurs by diffusion, active or passive transport.
<u>Explanation:</u>
Cell membrane are specifically penetrable, controlling which substances can go through, just as the amount of every substance can enter or exit at a given time. Specific permeability is fundamental to cells' capacity to get supplements, take out wastes, and keep up a steady inside condition unique in relation to that of the environment (homeostasis). Passive transport doesn't require the cell to consume any ATP and includes a substance diffusing down its concentration gradient across its membrane. In active transport, molecules cross the membrane using ATP.
Answer:
c
Explanation:
Think about when you have a can of coke too long in the freezer it expands. So same amount of product fill more space making can explode
The structure on the right is saturated while the structure on the left is unsaturated (presence of double bond). At room temperature the saturated fat will be solid and the unsaturated fat will be liquid.
High consumption levels of saturated fats are associated with heart problems. Consumption of high levels of saturated fats can raise your cholesterol levels and increase risk of heart disease.
Unsaturated fats are not associated with heart problems.
An example of saturated fat would be the fat found on red meat. An example of unsaturated fat would be the fat found in nuts, avocados, etc.
The answer is ATP molecules being produced, this happens in light and dark.
All of the other options are either directly related to light/photosynthesis or are needed to complete it.
Answer:
The correct answer is Option d. They line up in the middle of the cell.
Explanation:
Metaphase is a stage of mitosis in which condensation of DNA molecule into chromosomes occurs. During metaphase, nucleus is disappeared and chromosome becomes visible in the cytoplasm of the cell. There, the chromosomes line up in the middle of the cell.
