There is no carbon dioxide balance in biomass output or input. There is no dynamic equilibrium since carbon dioxide is being released at various rates. Geologically carbon dioxide concentration was very high for a long time and high enough to preclude evolving oxygen breathes until when carbon dioxide was locked up in plant life and oxygen levels raised by cyanobacteria and algae.
Oceans release carbon dioxide or it absorbs less carbon dioxide which causes a rise in temperature which feeds back. More heat is lost through evaporation which is lost to upper atmosphere then land biomass starts to pick up.
Answer:The rabbit is the primary consumer.
Explanation:
This is because DNA from a gene of interest can be inserted
into a plasmid, then the modified plasmid can be inserted into a bacterial cell
to make many copies of a gene of interest. Most plasmid vectors contain little
more than the essential nucleotide sequences required for their use in DNA
cloning: a replication origin, a drug-resistance gene, and a region in which
exogenous DNA fragments can be inserted.
Answer:
heart muscle
, skeletal muscle
, glandula and smooth muscle
Explanation:
The peripheral system distinguishes two major divisions: the afferent and the efferent. Afferent division is formed by the nerves that carry information to the central nervous system. In the efferent division the information travels from the central system to the effector organs, both muscular and other (including skeletal muscle, heart, glands, smooth muscle). Within the efferent division, in turn, two systems are distinguished, the somatic and the visceral or autonomous.
The somatic system conducts the signals that give rise to body movements and actions outside the body. It is formed by the fibers of the motor neurons that innervate the skeletal muscles; Their cell bodies are found in the spinal cord and a single axon reaches the muscle fibers it innervates. The action of these motor neurons always consists in the excitation and contraction of the muscles, although muscular activity can be inhibited by inhibitory synapses in charge of central system neurons.
The visceral system is formed by the fibers that innervate the smooth muscles, the heart, the glands and other non-motor organs or tissues, such as brown fat. It controls functions that are mainly related to the maintenance of internal environment conditions and also certain automatic responses to external stimuli. Regulates visceral activities such as circulation, digestion, thermoregulation.
