In computer science, a mutator method is a method used to control changes to a variable. They are also widely known as setter methods. Often a setter is accompanied by a getter (also known as an accessor), which returns the value of the private member variable
The correct answer is A.
The official guidelines from doctors state that infants should start consuming solid food after the age of six months. In order for the infants to be safe and healthy, they need to be able to sit up, support their back and chew safely before being given solid food.
Biodiversity is essential in medicine as most active chemicals used to make medicines are derived from plants or other organisms. Climate change today threatens species that are vital to medicine. An example would be coral reefs. Studies have been done on reefs that look at fighting cancers, HIV and other ailments. One of the richest zones of biodiversity is the tropics and this region is under threat from global warming and deforestation. It is important to preserve these species for use in future medicinal research. <span />
Answer:
The true statement is: "Spring tides are the highest, while neap tides are the lowest."
Explanation:
- The range of difference in the level of water between high and low tide is always larger in spring tide.
- Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun) balances the bulge of the ocean caused by the moon.
- This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.
Answer and explanation:
The meninges
There are actually 3 parts—dura mater, arachnoid, and pia mater.
The brain is soft and mushy, and without structural support it would not be able to maintain its normal shape. In fact, a brain taken out of the head and not properly suspended (e.g., in saline solution) can tear simply due to the effects of gravity. While the bone of the skull and spine provide most of the safeguarding and structural support for the central nervous system (CNS), alone it isn't quite enough to fully protect the CNS. The meninges help to anchor the CNS in place to keep, for example, the brain from moving around within the skull. They also contain cerebrospinal fluid (CSF), which acts as a cushion for the brain and provides a solution in which the brain is suspended, allowing it to preserve its shape.
The outermost layer of the meninges is the dura mater, which literally means "hard mother." The dura is thick and tough; one side of it attaches to the skull and the other adheres to the next meningeal layer, the arachnoid mater. The dura provides the brain and spinal cord with an extra protective layer, helps to keep the CNS from being jostled around by fastening it to the skull or vertebral column, and supplies a complex system of veinous drainage through which blood can leave the brain.
The arachnoid gets its name because it has the consistency and appearance of a spider web. It is much less substantial than the dura, and stretches like a cobweb between the dura and pia mater. By connecting the pia to the dura, the arachnoid helps to keep the brain in place in the skull. Between the arachnoid and the pia there is also an area known as the subarachnoid space, which is filled with CSF. The arachnoid serves as an additional barrier to isolate the CNS from the rest of the body, acting in a manner similar to the blood-brain barrier by keeping fluids, toxins, etc. out of the brain.
