Hello!
The answer would be Alveoli
In humans, oxygen and carbon dioxide are exchanged in the blood within many small sacs called alveoli in the lungs. Alveoli provide a large surface area for gas exchange.
Hope this helped!
Answer:
c trabajan independientemente sin coordinacion entre ellas
The correct option for the above statement is:
B. They save energy and metabolites and help the organisms to respond to the environmental changes.
Explanation:
Studies of organic phenomenon generally live the assembly of template RNA. Most mechanisms that management organic phenomenon do thus by dominant transcription, the synthesis of template RNA.
But there are other mechanisms for dominant the speed of supermolecule synthesis that occur downstream. Any step of the organic phenomenon is also modulated, from the DNA-RNA transcription step to post-translational modification of a super molecule. The subsequent may be a list of stages wherever organic phenomenon is regulated, the foremost extensively used purpose is Transcription Initiation: chromatin granule domains and transcription.
Answer:
Explanation:
The nervous system and the skeletal system interact in several ways.
What bones do for the nerves?
Provide calcium : almost all the calcium in the body (99%) is stored in bones. This is dynamic, so bones can take up and release calcium when needed. Calcium is essential for nerve cells, without it the nerves would not be able to convey signals.
Provide protection: the nervous system is protected by bones. The skull protects the brain and the vertebrae protect the spinal chord.
What do nerves do for bones?
Provide positional information: sensors and nerves in the joints detect mechanical deformation of ligaments and capsules. This way they can send information on the position of the body to the brain.
Protect joints: the same sensors and nerves that send positional information, also protect against injurious movement of the joints (too much flexion or extension).
Enable movement: this is more an indirect interaction. Nerves signal to the muscles to contract. Since the muscles are attached to the bones by tendons, this input makes movement of the body possible.
or...
"Your nervous system (brain and nerves) sends a message to activate your skeletal (voluntary) muscles. Your muscle fibers contract (tense up) in response to the message. When the muscle activates or bunches up, it pulls on the tendon. Tendons attach muscles to bones."
Answer:
Cytoplasm
Explanation:
Food processing plant performs the same job as Cytoplasm. Cytoplasm is a jelly like material that surrounds an organelle and allows food and oxygen to enter through the cytoplasm and reach the organelle.
