Answer: Eating a diet high in saturated fats, trans fats, and cholesterol has been linked to heart disease and related conditions, such as atherosclerosis. Also too much salt (sodium) in the diet can raise blood pressure. Not getting enough physical activity can lead to heart disease.
Explanation: Diet is an important risk factor in coronary heart disease. Heavy drinking may well increase heart attack, heart failure, stroke, and high blood pressure. A limit for men is 2 drinks a day, for women 1 drink a day.
The pyramid of energy shows that the variety and number of species decreases as you move to higher trophic levels. ... This is also assuming that the organisms of the higher trophic level only eat the one organism. To maintain energy levels, higher organisms must eat more food than those at the lower levels.

Answer:
The statement that says the cranial meninges have three layers of the dura mater is false.
Explanation:
The meninges are protective layers located between the central nervous system and its bone protection, both at the level of the brain and the spinal cord. The brain and spinal cord are surrounded by three membranous layers (cranial meninges), these are the dura mater, arachnoid mater and the pia mater, they are located one below the other.
The dura mater is the outermost strong fibrous tissue layer, formed by two layers of which the outermost one is attached to the bone and represents its periosteum. The innermost layer joins the arachnoid membrane. In addition to being the outermost meningeal, the dura mater is the hardest and most condensed of the three we have. Attached in part to the skull, this membrane protects the brain and acts as a structural support to the entire nervous system by dividing the cranial cavity into different cells.
The arachnoid mater, located in an intermediate zone between dura and pia mater, through this meninge and the space between arachnoid and pia mater it’s where the cerebrospinal fluid circulates; and protects the central nervous system against injuries.
The pia mater is the most internal, flexible meninge and in the greatest contact with the structures of the nervous system. In this layer you can find numerous blood vessels that supply the nervous system structures.
The spinal meninges are inside the spinal canal and encase the spinal cord. They have the same basic structure as the cranial meninges, composed of three layers: the dura mater, the arachnoid mater and the pia mater.
