I don't know sorry mark as brainliest please please
Student A who believes viruses are non living organisms.
Explanation- Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy.
Prophase is the first phase is when the two sister chromatids pair up and the nucleoli disappears. Prometaphase is the second phase where the microtubules begin to separate from each other, each pair of microtubules attach to the kinetochores and some nonkinetohore microtubules interact with those from the opposite pole of the spindle. Metaphase is the third phase where the chromosomes are lined up on the invisible line of the metaphase plate. Anaphase is the fourth phase where the two daughter chromosomes begin to separate from each other to opposite poles. Telophase is the last phase where the two daughter nuclei form creating two identical nuclei.
An electron carrier is a molecule that transports electrons during cellular respiration. ... The energy stored in NADH + H+ and FADH2 will be released later in cellular respiration to generate ATP, which can be used as an energy source throughout the cell.
Answer:
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
Explanation:
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. For example, water, ions, glucose and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity. Similarly, signaling molecules may need to enter the cell and proteins may need to be released into the extracellular matrix. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing and rate of movement of these molecules.
