the answer is... hydrocarbons
Answer:
a. synergism
Explanation:
When two different drugs inhibit a single biochemical pathway of microbes less quantity of each drug is required in combination to produce the effect than when used separately. This effect is called synergistic interaction of drugs.
Both beta-lactam antibiotics such as penicillin and cephalosporin and clavulanic acid serve as beta-lactamase inhibitors and inhibit the beta-lactamase-producing bacteria. Therefore, beta-lactam antibiotics and clavulanic acid are used in combination to control these enteric bacteria.
Answer:
green is the dominant trait and yellow would only be found in the second generation when 2 passive yellow genes can come together a green or yellow or green w green trait will always be green a pea can only be yellow with 2 recessive yellow genes
Explanation:
One of the major problems of monoculture farming is the variety of species. If there are no varieties in the producer level in the food chain all other organisms within the ecosystem would be affected.
Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,
Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.
The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.
Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.
In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.
The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.
Unmyeinated lacks myelin sheath,therefore the exchange and the rate of diffusion of ions along the axons is low.
