Antibiotics stop the bacteria growth, reproduction or destroy the bacteria.
Explanation:
Antibiotics are known as those popular medicine which is helpful and also can fight for certain type of infection. Their main role is to stop their growth, reproduction or otherwise destroyed it.
The first antibiotics was penicillin. Antibiotic is using to stop the allergic reaction but it must be prescribed by doctors. Antibiotics also have side effects. Due to excess use of antibiotics abnormal blood clotting happens.
The right answer is <span>Refractory period.
At the moment when the action potential is emitted, the fiber being depolarized, it is impossible to depolarize it again. It is, therefore, necessary to wait until the membrane potential returns to a value below the critical threshold in order to be able to excite it again. We are thus led to distinguish two periods that characterize its excitability.
An absolute refractory period: during which any stimulation, even supraliminal, is ineffective since the fiber is already depolarized.
A relative refractory period: during which a second action potential can be omitted provided that the depolarization produced by the excitation reaches the critical threshold, which implies that it is more important since the value of the resting potential has not been restored yet.</span>
The answer for this question is B
Answer:
D I'm pretty sure i hope i'm right
Given the characteristics mentioned in the question, the animal must be an annelid.
<h3>What is an annelid?</h3>
Annelids, (Phylum name annelida) segmented worms, characterized by having body cavities (or body coelom), mobile bristles (or setae), and bodies segmented by transverse rings. The body cavity is reduced in leeches, and the bristles are devoid of some specialized morphology, including leeches. An important phylum of invertebrates in the animal kingdom, Annelida, consists of more than 9,000 species divided into three classes: Sea worms (polychaetes) are divided into motile and sedentary or tube-dwelling forms. earthworms (Oligochaeta); and leeches (Hildinea). Annelids are coelomic and tridermal.
General characteristics of annelids are:
- They show organization at the organ system level.
- Your body is segmented.
- They breathe through their body surfaces.
- The kidney is an excretory organ. They have well-developed circulatory and digestive systems.
- Common names for more familiar annelids include earthworms, sandworms, annelids, bristleworms, and leeches.
