What is the habitat of the starfish and what does it eat

1 answer:

7 0

Starfish, or more accurately sea stars, fill a niche as predator and prey in marine ecosystems close to shore. With more than 18,000 species in the world, they range from the tropics to the Pacific Northwest and further north. They can grow larger than a foot across and can have as many as 40 arms. While sea stars are known for their ability to regrow lost arms, they have an unusual digestive system, too.

Algae: any of numerous groups of chlorophyll-containing, mainly aquatic eukaryotic organisms ranging from microscopic single-celled forms to multicellular forms 100 feet (30 meters) or more long, distinguished from plants by the absence of true roots, stems, and leaves and by a lack of nonreproductive cells in the reproductive structures: classified into the six phyla Euglenophyta, Crysophyta, Pyrrophyta, Chlorophyta, Phaeophyta, and Rhodophyta.

Amboeda: any of a large genus (Amoeba) of naked rhizopod protozoans with lobed and never anastomosing pseudopodia, without permanent organelles or supporting structures, and of wide distribution in fresh and salt water and moist terrestrial environments

Asexual reproduction: reproduction (as cell division, spore formation, fission, or budding) without union of individuals or gametes

Cilia: minute short hairlike process often forming part of a fringe

Diatom: any of a class (Bacillariophyceae) of minute planktonic unicellular or colonial algae with silicified skeletons that form diatomaceous earth

<span>Similarities and Differences
There are many similarities and differences between the three domains. Bacteria and Archaea differ in how they gain energy. Bacteria gain energy either by being phototrophs, lithotrophs or organotrophs. One similarity between domain Archaea and domain Bacteria is that they both contain only prokaryotes while domain Eukarya only contains eukaryotes. Domain Archaea is the only domain that is sensitive to antibiotics. Another similarity between domain Bacteria and domain Eukarya is that Methionine is the first amino acid seen during protein synthesis while in domain Archaea, the first amino acid is Formylmethionine. The last major similarity between domain Archaea and domain Bacteria is that they do not contain any organelles while domain Eukarya does. A difference between all three domains is what their cell walls contain. A cell wall in domain Archaea has peptidoglycan. The organisms that have a cell wall in domain Eukarya, will have a cell wall made up of polysaccharides.</span>

If water molecules inside and outside of a cell became non polar , how would the transport of materials in and out of the cell b

postnew [5]

<h2>Answer:</h2>

The water will move in and out freely. The material transport which is due to the water transport will be affected.

<h3>Explanation:</h3>

Water is a partially polar molecules. Many ionic compounds and ions travel inside and outside the cell due to attachment with water molecule.
As well as water movement is controlled due to its polar nature through cell membrane. and the cytoplasm and outer environment is separate due to non polar cell membrane.
If the water become non polar then the movement through cell membrane will be easy for water. And the molecules dissolved in water will also be transported uncontrollably.
