Biology
1 answer:
qwelly [4]3 years ago
3 0
Cnidarians have one body opening. There is no mouth or anus. Instead, food particles are drawn into the body by movement of water. Inside the body cavity are specialized cells called amoebocytes and collar cells that help digestand remove wastes. Cnidarians with the opening at the top have body plans called polyps, such as corals. Those with the opening underneath have a medusa body form, such as jellyfish.

Without this, many cycles such as the water cycle and photosynthesis would not exist. What could all these cycles not exist with
fgiga [73]

Answer:

This question appears incomplete

Explanation:

This question appears incomplete. However, one similar substance that, if missing, many cycles (particularly the two cycles/processes provided in the question) will not exist/proceed is the sun/sunlight.

In the water cycle for instance, if there is no sun/sunlight, there will be no heat to allow for evaporation of water from the water-body (ocean, sea, stream or lake) hence there will be no cloud of water droplets in the atmosphere. The implication of this is that, the first process of the water cycle will not proceed, hence the cycle will not exist.

During photosynthesis, carbondioxide reacts with water in the presence of sun/sunlight to produce glucose and oxygen. The absence of sun in this reaction will not lead to the production of glucose which is the useful product of photosynthesis for plant.

From the explanation above, it can be deduced that <u>the absence of the sun/sunlight will prevent the two cycles from existing</u>.

What loop prevention technique is implemented by distance vector routing protocols?
Ira Lisetskai [31]
The loop prevention technique implemented by distance vector routing protocol is  SPLIT HORIZON.
Routing loop is a common problem that is associated with networks. Routing loop is said to occur when an error arise in the operation of the routing algorithm which leads to formation of nodes and loops in the path to a particular destination. Split horizon is one of the feature that is used to prevent distance vector routing.<span />
