Mitochondrion a singular word for mitochondria is a "powerhouse" organelle of the cell. 

Mitochondrion is an important organelle in most living organisms because it is where biochemical processes of living organisms such as respiration takes place. The mitochondrion has a smooth outer membrane but a larger inner membrane. The inner membrane is about 70% protein and is very convoluted because that can even fit inside the outer membrane. Mitochondrion is the carrier of the Kreb's cycle in the matrix and it is responsible for the transfer of electron chain found in the cristae of the inner membrane.

nikdorinn [45]

Answer:

Motor nerves

Explanation:

Pulling the leg quickly from the sharp object is an example of reflex action. It includes sensory receptors, sensory neurons, interneurons, the control center (spinal cord), motor neurons and effector.

As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.

SIZIF [17.4K]

Answer:

Letter A indicates the epidermis, which is the outer layer of the root.

Explanation:

The internal structure of the eudicot root consists of three concentrical layers: The epidermis, the cortex, and the central vascular cylinder.

The epidermis is the outer layer of the root. It covers the totality of the root surface, absorbs water and minerals from the soil, and protects the internal tissues.

The cortex occupies a big part of the root and its located under the epidermis. The most internal cell layer of the cortex is called endodermis.

The vascular cylinder is composed of vascular tissues -the xylem and the phloem- that is surrounded by one or more cell layers called pericycle. The xylem looks like a cross of big cells in the center, and the phloem occupies the spaces between the pericycle and the xylem.
