Among organisms exhibiting protostome development, which morphological trait shows the most variation?

Answers

Answer 1

The morphological trait that shows the most variation among organisms exhibiting protostome development is the type of body cavity.

What are protostomes?

Protostomes are animals having bilateral symmetry in which the mouth is developed before the anus.

The organisms (protostomes) represent the main classification feature of animals according to the type of embryo development.

The genetic analysis of molecular sequences has shown that protostomes emerged first in the evolution in the animal kingdom.

Protostomes include diverse groups of animals such as annelids, nematodes, arthropods,  mollusks, flatworms, etc.

In conclusion, the morphological trait that shows the most variation among protostomes is the type of body cavity.

Sound waves travel better through solid than through a gas. Explain why this is true.

Answers

Answer:

solids are more tightly packed together (the molecules) than liquid or gas so it allows it to travel through vetter/faster

Answer:

Explanation: Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids. The distances in liquids are shorter than in gases, but longer than in solids. Gases are the slowest because they are the least dense: the molecules in gases are very far apart, compared with solids and liquids

Young hermit crabs pick up sea anemones which live on their shells. The stingy tentacles of the anemone keep fish from eating the hermit crab, and the sea anemone is able to eat leftover food from the hermit
crab. Which best describes the relationship between the sea anemone and the hermit crab?
A commensalism
B. O mutualism
c. parasitism
DO predation

Answers

Answer:

mutualism.

Explanation:

Mutualism can be defined as an symbiotic relationship or interaction between two or more living organisms of different species that typically involves each organism benefiting positively. Therefore, mutualism influences the survival and reproduction of living organisms in their habitats.

In this scenario, young hermit crabs pick up sea anemones which live on their shells. The stingy tentacles of the anemone keep fish from eating the hermit crab, and the sea anemone is able to eat leftover food from the hermit crab. Therefore, the relationship between the sea anemone and the hermit crab is best described as mutualism because both of them are benefiting from the interaction.

Simply stated, the sea anemone provides protection (security) from predators for the hermit crab while the hermit crab provides food for the sea anemone.

Anatomy
Label each of the following structures or processes.

Answers

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.

cycle and oxygen cycle ​

Answers

What organism? If its plants, they give oxygen during the day and carbon dioxide in the night. While animals give carbon dioxide but take oxygen from the air. These carbon dioxide gas and oxygen gas go to the atmosphere and affect the carbon cycle and oxygen cycle.

Here is the cycle if you want to know more

Plants (give out oxygen) -> Animals (Use oxygen) + (given our carbon dioxide) -> plants (take oxygen)

and so on

Answer:

Plants take carbon from the atmosphere in the form of carbon dioxide during photosynthesis. Plants and animals both release carbon dioxide back into the atmosphere through the process of respiration. When organisms die, some of the carbon in their bodies is stored in the soil, which can be reintroduced into the atmosphere through soil respiration.

Classification of organisms is defined as dividing living beings into different kingdoms based on their genetics, traits, and other features.

Why did Classification Schemes of taxonomists change?

Taxonomists arrange and divide the organisms based on the DNA, traits, and features of the living organisms.

The advancements in technology led the taxonomists to have more information on genetic lineage and arrange them accordingly.

Introduction and discoveries of new species, their genetic make-up, and traits also contribute to the change of classification system.

Molecular biology, cellular level studies, and genetics of species have contributed to the classification of organisms.

Thus, the given statements about the classification of organisms are correct.

How do the distances between the terrestrial plants compare to the distances between the gas giants?

Answers

Answer:

They are different from rocky or terrestrial planets that are made of mostly rock. Unlike rocky planets, gas giants do not have a well-defined surface – there is no clear boundary between where the atmosphere ends and the surface starts! The gas giants have atmospheres that are mostly hydrogen and helium.

Explanation:

I hope this helps!

They vary from planets that are predominantly made of rock, such as rocky or terrestrial planets. Unlike solid planets, gas giants lack a clearly defined surface, there is no discernible line separating the atmosphere from the surface.

What are terrestrial planets?

Telluric planets are another name for terrestrial planets. The Latin words terra and tellus, which both indicate Earth, are the source of the words terrestrial and telluric, respectively.

While the terrestrial planets were warmed by the sun's rays, the Jovian planets developed above the frost line.

Worlds that could float on water and worlds appropriate for manned missions were created under very distinct circumstances, but they have some striking similarities. Every world in our solar system is different.

Therefore, the atmospheres of the gas giants are primarily composed of hydrogen and helium.
