The correct answer is: Sodium and potassium ions move by active transport, and glucose moves by facilitated diffusion.
Because sodium and potassium are moved through cell membrane against their concentration gradients, transport requires energy (ATP), so it is active. <span>Glucose is a polar molecule and because the plasma membrane is impermeable to polar molecules transport of this important nutrient is accomplished by carrier proteins. This process is called facilitated diffusion and it is passive transport (doesn’t require energy).</span>
Answer:
it is b: to provide energy for their activities.
Explanation:
the organelle that's labeled x is a mitochondria.
The rocks are in dry climate.
The relative permanence or “toughness” of the rock prone to weathering absolutely depends partially on sort of rock it is. This is because rock type is defined by the structure and relationship of the constituent metals, and complex metals vary in how they endure up to weathering.
Several types of rock, like granite, are very repellent to weathering. Moreover, Igneous rocks serve to heat slowly because it is difficult for water to penetrate into them.
Answer:
Vitamins also help your body use energy from the food you eat. Minerals are chemical elements that help regulate your body's processes. Potassium, for example, helps your nerves and muscles function. Calcium helps your teeth and bones stay strong.
