Answer:
The characteristics to the correct phylum matching is given below:
Explanation:
- Organisms lack symmetry- Porifera. Poriferans such as sponges are without any symmetry, thus they are asymmetrical.
- Organisms have specialized stinging cells -Cnidaria. Cnidaria such as <em>Hydra</em> possesses stinging cells or cnidocytes located around the mouth and tentacles of the <em>Hydra</em> and can kill prey with toxins.
- Adult forms are sessile – Porifera. Adult sponges are sessile and spend their lives attached to a substrate.
- Two types of body plan exist as polyp and medusa – Cnidaria. Cnidarians show two distinct body plans as polyp or stalk and medusa or bell. Polyps are non-motile and Medusa are motile.
- Organisms obtain food by filtering water– Porifera. The water moves through the body of the poriferans to filter out food, absorb dissolved oxygen.
- Phenomenon of alternation of generation is observed - Cnidaria. Alternation of generation is a type of life cycle which switches between two forms. In cnidarian, the asexual polyp alters with the sexual medusa.
Answer:
Secretes a protective covering against UV damage
Explanation:
Keratinocytes is an important protective organelle that work with melanocytes to produce melanin in the skin to protect damages from the UV
<span>The respiratory system supplies the body with oxygen, which provides energy to the cells. Another important function of the respiratory system is to remove carbon dioxide from the blood stream</span>
Answer:
If you don't continue an accurate antibiotic treatment, compliting it course, you encourage development of antibiotic resistance in bacteria, which can become difficult to treat with the same antibiotic or cause a bacterial regain and cause a severe infection. It can also become life -threatening in the future leading to difficult results in treatment with the same antibiotic or others.
Explanation:
Answer:
The living world can be organized into different levels.
Levels of organization are structures in nature, usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level. Typical levels of organization that one finds in the literature include the atomic, molecular, cellular, tissue, organ, organismal, group, population, community, ecosystem, landscape, and biosphere levels.
Explanation:
Yet, in spite of the ubiquity of the notion, levels of organization have received little explicit attention in biology or its philosophy. Usually they appear in the background as an implicit conceptual framework that is associated with vague intuitions. Attempts at providing general and broadly applicable definitions of levels of organization have not met wide acceptance. In recent years, several authors have put forward localized and minimalistic accounts of levels, and others have raised doubts about the usefulness of the notion as a whole.
Just helps a lot overall, especially if you are planning to go into a field related to biology. Hope this helps! :)
