By the way, I LOVE BIOLOGY!
the characteristics of prokaryotes are:
- Lack an organised nucleus and other membrane organelles
- Found in a central part of the cell which is known as the Nucleoid
- The cell wall of the prokaryotic cell acts as an extra layer of protection as it can help maintain dehydration and the cell shape
(Got the information from my biology notes!)
F1 stands for first filial (daughter) generation
<span>F2 stands for second filial (daughter) generation</span>
Their purpose is reproduction.
Answer:
The correct option is b) motor output of the spinal cord
Explanation:
Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.
The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.
Answer:
This is because antibiotic resistance can be caused by bacteria getting the ability to be unaffected by the antibiotics Also, people not taking their medication for the entire duration exposes the bacteria to the antibiotic and makes it stronger. Also, when people overuse antibiotics and mutations occur, the bacteria becomes antibiotic resistant.
