why are myxozoans actually a bad example of supposed evolution in action?
(I will give the best answer brainiest and extra points)
Explanation:
Myxozoans (phylum Myxozoa) are metazoan parasites utilizing invertebrate and (mainly) aquatic vertebrate hosts. They have in common with cnidarians the possession of virtually identical, highly complex organelles, namely the polar capsules in myxozoan spores, serving for attachment to new hosts and the nematocysts in surface epithelia of cnidarians, serving for food capture. Although myxozoan spores are multicellular, the simple trophic body forms of almost all species, reduced to syncytial plasmodia or single cells, reveal no clues to myxozoan ancestry or phylogenetic relationships. The myxozoan genus Buddenbrockia is one of only two known genera belonging to a clade which diverged early in the evolution of the Myxozoa. Today the Myxozoa are represented by two classes, the Myxosporea, containing all the better-known genera, which alternate between fish and annelids, and the Malacosporea, containing Buddenbrockia and Tetracapsuloides, parasitising bryozoans. The latter genus also infects salmonid fish, causing proliferative kidney disease (PKD). The enigmatic Buddenbrockia has retained some of its ancestral features in a body wall of two cell layers and a worm-like shape, maintained by four longitudinally-running muscle blocks, similar to a gutless nematode and suggestive of a bilaterian ancestry. Although some analyses of 18S rDNA sequences tend towards a cnidarian (diploblast) affinity for myxozoans, the majority of these studies place them within, or sister to, the Bilateria. The latter view is supported by their possession of central class Hox genes, so far considered to be synapomorphic for Bilateria. The simple body form is, therefore, an extreme example of simplification due to parasitism. Various hypotheses for the occurrence of identical complex organelles (nematocysts and polar capsules) in diploblast and triploblast phyla are evaluated: common ancestry, convergent evolution, gene transfer and, especially, endosymbiosis. A theory of the evolution of their digenetic life cycles is proposed, with the invertebrate as primary host and secondary acquisition of the vertebrate host serving for asexual population increase.

what is the difference between chromosomes and sister chromatids in the m phase?
Answer:
Before cell division must occur, the chromosomes must replicate themselves. Sister chromatids are the two initially identical copies.
Scientific theories can be disproven or modified. True or false?
why do you think the demand for solar energy is increasing at this time ?
Answer:
Other energy sources which are non-renewable are becoming more and more scarce, such as coal. Due to the lack of such resources, people are looking towards renewable sources of energy such as solar energy.

Why are the structures of plants ideal for photosynthesis and plant reproduction?
Answer:
Why are plant reproductive structures ideal for plant reproduction? Plants reproduce using seeds and spores. ... Plants cannot move by themselves, but seeds and spores can be carried from one location to another. This allows plants to colonize other areas.
Explanation:
Hope it helps
Is this the right one lmk!!!!
Answer:
ya i think
Explanation:
Weather Patterns are a result of
patterns of movement of:
Air pressure is the number of air molecules packed into an area. Changes in atmospheric pressure create weather patterns, which we'll discuss later on. ... Wind is the movement of air through the atmosphere, and it helps to move air from high-pressure areas to low-pressure areas.

Which one of the following is foliated?
a. schist
b. marble
c. anthracite
d. quartzite
A: a. schist
E: Foilated: the texture of metamorphic rock in which the mineral grains are arranged in planes or bands. Schist is a metamorphic rock with well-developed foliation. It often contains significant amounts of mica which allow the rock to split into thin pieces. It is a rock of intermediate metamorphic grade between phyllite and gneiss.

what action describes a chemical change?
freezing water, melting ice, lighting a match, or crushing rock.
Answer:
Lighting a match.
Explanation:
When the match burns it goes through a chemical change due to the materials such as phosphate, sulfur, etc. The heat then burns the phosphorous on the match's head.
Sorry if it didn't make sense.
Answer:
Lighting a match
Explanation:
Lighting a match and letting is burn is an example of a chemical change because the two reactants (fire and the match) form a new substance. Freezing water, melting ice and crushing a rock are physical changes because they only change in size, shape or form.
What does the water molecule do in the Lithosphere during the Water Cycle.
Answer:It's a process that happens on a molecular level when the molecules of water are really energized and rise into the air.
Explanation:
The water comes out of the atmosphere and makes it to the surface
Water moves from the ground or oceans into the atmosphere through a process called evaporation.
How can a physical change to an environment affect the number of organisms in an ecosystem?
It can cause a chain reaction. Every cause has an effect.
Example: Someone throws a cigarette out their window, causing a grass fire
Scenario A: A prairie dog population was killed in the grassfire simply because they had no time to escape.
Scenario B: The grasshoppers don't have grass to eat, so the prairie dogs don't have meat to survive because the grasshoppers are starving. Either way, the person who threw the cigarette caused a decrease in the population.
Please give me the answer fast. Thank you. Best answer gets brainliest
Answer:
Enzymes work best and are more efficient at a certain temperature. This is called the 'optimum temperature'. This investigation was carried out at 40° as this temperature allows more collisions among the molecules, thus being the optimum temperature for enzyme activity.
Higher temperatures causes the enzymes to be denatured .
if a 1st quarter moon phase appears on the night of july 4th, what is the approximate date in which a 3rd quarter moon will appear in the night sky?
Answer:
18th of July
Explanation:
Given that each quarter of a moon phase occurs after seven days, hence, if a 1st quarter moon phase appears on the night of July 4th, the approximate date on which a 3rd quarter moon will appear in the night sky on the 18th of July.
This is because, after the first quarter of a moon phase of July 4th, the second quarter of a moon phase will occur on the 11th of July, while the third quarter will occur on the 18th of July.

Describe how X-linked traits are inherited
Answer:
X-linked recessive inheritance is a way a genetic trait or condition can be passed down from parent to child through mutations (changes) in a gene on the X chromosome. In males (who only have one X chromosome), a mutation in the copy of the gene on the single X chromosome causes the condition.

Leopards and lancelets have no common ancestor.
1. True
b. False
The taxon that shares the most recent common ancestor with frogs is the bass.
1. True
b. False
In this tree, frogs are the sister taxon of turtles and leopards.
1. True

1. True
b. False
The common ancestor of lamprey and lancelets have a vertebral column.
1. True
b. False
Answer:
Explanation:
1) False.
This is because bass is a fish, turtle is an amphibian and leopard is a mammal. But bass possess some characteristics traits related to turtle as compared to a mammal(leopaard)
2) False
This is because their ancestor is a Chordate , therefore they have a coin ancestor.
3) True
The taxa of turtles( amphibians) share a more common ancestor with frogs compared to bass because both are amphibians.
4) False
This is because the bass is a fish that possess some characteristics traits related to an amphibian (turtle) as compared to a mammal(leopard).
5) True
They all have the fore limb and hind limb.
6 True.
