Answer:
The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient . ... Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.
The brain is divided into lobes that carry out different kinds of functions. There are 5 lobes in the brain:
1. Frontal lobe: Concentration, planning, problem solving, etc are the function performed by this region of the human brain.
2. Parietal lobe: Touch, pressure, taste and body awareness is processed by this lobe.
3. Temporal lobe: Long-term memory, hearing, emotions are processed in this lobe.
4. Occipital lobe: Sight is processed in this lobe.
5. Cerebellum: Coordination and balance, fine motor control are performed by this part of the brain.
The modern neuroscience has also confirmed the presence of brain waves like the alpha, beta, theta and gamma rhythm that sweep across the different lobes and regions of the brain. These waves are known to result from the collective activity of neurons in each of the regions. The brain waves are studied to check the activity of the regions that are coordinating together to carry out a particular type of task.

Answer:
The skull is from a fossil skull of Styracosaurus - a horned dinosaur.
Explanation:
This skull image is the skull of a Styracosaurus dinosaur who was a huge dinosaur almost 5 meters or more with the horned present on the skull. This is a fossil skull representation from the fossils.
Styracosaurus was present 75 million years ago during the Cretaceous period who was a completely herbivorous ceratopsian dinosaur.
Thus, the skull is from a fossil skull of Styracosaurus - a horned dinosaur.
Why temperature affects heart rate in ectothermic organisms? If the temperature is within the optimal range for enzyme activity more ATP will be produced and the heart will beat faster due to increased metabolic activity and energy availability.
