why is it important that root hair cells have high ion concentration?
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Describe the basic function of each of the three leaf tissues
Answer:
Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss.
Explanation:
Answer:
Main function of stomata is exchange of gases between the internal tissues and the external atmosphere. Cuticle is present on the outer wall of epidermis to check evaporation of water. Epidermis forms a Protective layer in leaves, young roots, stem, flower, fruits etc

HELP!!! A student observes that she's always sleepy shortly after eating lunch, and she wants to be able to pay better attention in her mid-afternoon class. She tried doing 10 jumping jacks just before the class, but still felt sleepy around the middle of the class. The next day, she tried sipping water throughout the class and found that she could pay attention until the end of the class. The student now brings a water bottle to class.
*Identify how this student applied the scientific method to solve her problem.*
Answer:
In this scenario, the student applied the scientific method to solve her problem in that she first established there was a problem, then formulated some hypotheses about why there was a problem, and then did experiments to test the hypotheses.
Explanation:
Hope This Helps!
It's essential for students (and everyone) to stay adequately hydrated throughout the day to maintain overall well-being and cognitive function. Bringing a water bottle to class is a practical and healthy habit that can help the student remain focused and attentive during the class and other daily activities.
Hydration and Cognitive Function: Proper hydration is essential for optimal cognitive function. When the body is dehydrated, it can lead to feelings of fatigue and decreased mental alertness. Drinking water helps maintain the balance of body fluids, and the brain relies on adequate hydration to function at its best.
Blood Flow and Oxygenation: Staying hydrated supports proper blood circulation, including to the brain. Sipping water can help ensure that oxygen and nutrients are efficiently delivered to brain cells, enhancing cognitive performance.
Thirst as a Sign of Dehydration: Feeling sleepy or fatigued after eating lunch could be a sign of dehydration, especially if the lunch is salty or doesn't contain enough fluids. By sipping water during the mid-afternoon class, the student is addressing any potential dehydration and its associated effects on attention and alertness.

The liver is the largest solid internal organ of the human body. It is located in the abdominal region. To be precise in the upper right-hand side of the abdomen, just below the diaphragm. The liver has a variety of functions including:
Enzymatic functionsProduction and excretion of bileExcretion of substances (eg hormones)Storage of glycogen and nutrientsDetoxification of bloodamong a few others.
The liver acts as the primary filter for the body's blood. It filters out toxins, breaks down chemicals through enzymatic processes, and removes alcohol from the blood. These processes create waste products known as urea and bile, which are excreted by the liver to be removed from the body by other organs.
