Among coelomates, which of these develops by spiral cleavage and the mouth forms before the anus

nekit [7.7K]

Answer:

Protosomes

Explanation:

Protosome is a multicellular organism whose mouth grows before the anus from a primary embryonic opening which includesphyla mollusk, arthropod or annelid. Protosomes are developed by spiral cleavage during embryo development.

Protosome animals have bilateral symmetry and three germ layers. Some of the examples of protostomes are snails and slugs (mollusk), earthworms (annelids), and spiders, lobsters, barnacles (arthropods).

Hence, the correct answer is Protosomes .

Choose ALL of the phases of matter listed that are able to flow: gas liquid solid

IrinaK [193]

Answer:

- gas

- liquid

Explanation:

Part of the definition of gases and liquids is the ability to flow, so this answers your question.

Why does this not apply to solids? The cells in a solid are closer together with less room for movement, so they do not "flow" like gasses or liquids. You can think of the device you are asking this question on versus the water in the ocean.

Note: Gas can still flow, but it does not flow the same as water. It depends on what you are being taught for if gas flows or not.

-> Liquid flows from high to low only, while gas can flow in all directions

Have a nice day!

madam [21]

Aerobic cellular respiration, glucose is metabolised in the presence of oxygen and leads to the formation of energy as a main product. the by products are carbon dioxide and water. The process takes place in four phases: glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation.

Development and Applications of a High Throughput Genotyping Tool for Polyploid Crops: Single Nucleotide Polymorphism (SNP) Array.

Polypoid species play significant roles in agriculture and food production. Many crop species are polyploid, such as potato, wheat, strawberry, and sugarcane.

Genotyping has been a daunting task for genetic studies of polyploid crops, which lags far behind the diploid crop species.

Single nucleotide polymorphism (SNP) array is considered to be one of, high-throughput, relatively cost-efficient and automated genotyping approaches.

However, there are significant challenges for SNP identification in complex, polyploid genomes, which has seriously slowed SNP discovery and array development in polyploid species.

Ploidy is a significant factor impacting SNP qualities and validation rates of SNP markers in SNP arrays, which has been proven to be a very important tool for genetic studies and molecular breeding.

This review presents a complete overview of SNP array development and applications in polypoid crops, which will benefit the research in molecular breeding and genetics of crops with complex genomes.
