Which statement is false in reference to the cranial meninges?have the same basic structure as the spinal meningeshave three lay
earnstyle [38]

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.

About how much energy is transferred from a producer to a primary consumer?
devlian [24]

Answer: The correct answer is C)  10% of the plant's energy.

In an ecosystem, there are various trophic levels, which form the part of the food chain. Producer like plants forms the first trophic level as they synthesize their own food via photosynthesis.

The energy from producers is transferred to the primary consumers. It is only 10% of the producer's energy.

This is in accordance with the 10% law of energy transfer. According to this law, only 10% of the energy is transferred from one trophic level to the next trophic level in an ecosystem. This is because the rest of the energy is utilized by the organism or released as heat in the environment.

Thus, option C) is the right answer.
