Which observation supports the claim that the lophophore either evolved more than once or was lost in many lophotrochozoans?

1 answer:

8 0

The observation that supports lophophore evolved more than once is not all lophotrochozoans use a ring of ciliated tentacles for food collection and gas exchange.

<h3>What are lophotrochozoans?</h3>

Lophotrochozoans represent a well-defined group of animals that are characterized to be protostome species.

These animals (lophotrochozoanns) include different taxonomic groups such as, for example, worms or annelids, mollusks, brachiopods, Platyhelminthes, etc.

The lophotrochozoans represent a polyphyletic taxonomic group from a non-strictly evolutionary point of view but instead, composed of species that have a structure referred to as lophophore, a collection of ciliated tentacles surrounding the mouth.

In conclusion, the observation that supports lophophore evolved more than once is not all lophotrochozoans use a ring of ciliated tentacles for food collection and gas exchange.

why are the polio virus unable to reproduce if their DNA base sequence is different from the normal virus?

maks197457 [2]

Answer:

When the virus infects a cell, the RNA genome enters the cell and programs it to make new virus particles. These virus particles are released from the cell and go on to infect new cells. In humans, poliovirus is ingested, and replicates in cells of the gastrointestinal tract.Poliovirus, the prototypical picornavirus and causative agent of poliomyelitis, is a nonenveloped virus with a single-stranded RNA genome of positive polarity. The virion consists of an icosahedral protein shell, composed of four capsid proteins (VP1, VP2, VP3, and VP4), which encapsidates the RNA genome (1).RNA viruses generally have very high mutation rates compared to DNA viruses, because viral RNA polymerases lack the proofreading ability of DNA polymerases. The genetic diversity of RNA viruses is one reason why it is difficult to make effective vaccines against them.

Why is redi's experiment a good example of a controlled experiment

Step2247 [10]

A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.

Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.

This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.

Redi was trying to prove spontaneous generation with his experiment. Although, it failed.

Spontaneous generation: When life forms from non-livings.

Redi disproved spontaneous generation, but proved biogenesis.

Biogenesis: When life comes from other living beings.

He proved biogenesis because the flies had reproduced when the jar was opened.

mrs_skeptik [129]

Answer:

I think that birds have different bill lengths because of their habitats and their diet. Also natural selection and evolution has also played a factor due to the fact that birds have not always looked the way that they do now, for example the Archaeopteryx a bird that lived around the time of the dinosaurs had a shorter and more powerful bill to grind insects and small mammals
