Animals with deuterostome development, bilateral symmetry as larvae, and five-part radial symmetry as adults are called Echinoderms.
An echinoderm is any member of the phylum Echinodermata. The adults are recognizable by way of their (generally five-factor) radial symmetry, and encompass starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, in addition to the ocean lilies or "stone lilies".
Person echinoderms are found on the sea mattress at every ocean depth, from the intertidal quarter to the abyssal zone. The phylum incorporates about 7,000 dwelling species, making it the second-biggest grouping of deuterostomes, after the chordates. Echinoderms are the biggest completely marine phylum. The primary definitive echinoderms seemed close to the beginning of the Cambrian.
The echinoderms are critical both ecologically and geologically. Ecologically, there are few other groupings so plentiful inside the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are capable of reproducing asexually and regenerating tissue, organs, and limbs; in a few cases, they are able to undergo entire regeneration from a single limb.

How does the phosphorus cycle work step by step?
The steps of the phosphorus cycle function are:
Phosphorus enters an ecosystem through weathering of rocks and soil, and is taken up by plants through their roots.Animals consume the plants, and phosphorus is passed through the food chain. Animals excrete phosphorus-containing waste, which is absorbed back into the soil.Decomposers break down the phosphorus-containing waste, releasing phosphorus back into the soil.The phosphorus is taken up by plants and the cycle begins again.The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the environment. Phosphorus is an essential nutrient for all forms of life, and it cycles between organisms and the environment.
In the environment, phosphorus cycles between the land, water, and air. It is found in rocks and soil, and it is taken up by plants and animals.

What blood type if parents are AB and O?
If the blood type of parents are AB and O, the blood type of the offspring can be either A or B.
The blood type in humans is determined by the ABO gene. There three types of ABO gene, which are, A, B and O. The O gene is recessive to A and B. An individual can have one of the four blood types namely, A blood type (AA or AO), B blood type (BB or BO), AB blood type (AB) and the O blood type (OO).
If the parents have AB and O blood type, their genotypes must be AB and OO respectively. When we cross these genotypes, we obtain two possible genotypes in the offspring which are AO (A blood type) and BO (B blood type). Therefore, an offspring born to parents with AB and O blood type can only be either a A blood type or B blood type.

initiates DNA synthesis by making short RNA segments at the replication fork, what results?
Initiates DNA synthesis by making short RNA segments at the replication fork, resulting in two branches each consisting of a single strand of DNA.
The replication fork or replication fork is the structure formed when DNA replicates. Replication This fork forms the effect of the enzyme helicase which breaks the hydrogen bonds that identify the two DNA strands, causing them to unfold the double strand into two branches, each consisting of a single DNA strand.
Each of these branches becomes a "mold" for the formation of two new DNA strands based on their complementary nucleotide sequence. DNA polymerase forms a new DNA strand by extending the oligonucleotides that are formed by the primase enzyme and are called primers.

An organic synthesis to make the pain reliever acetominophen is supposed to produce 280 kg of product but instead produces 70 kg of waste in addition to the acetaminophen. What is the percent yield?.
When making acetaminophen which yields 280 kg of product but produces 70 kg of waste other than acetaminophen, the percent yield is 75%.
Here we know that the theoretical weight is the weight of the acetaminophen that should be produced if the reaction occurs efficiently, while the experimental weight is the weight of the acetaminophen obtained in the synthesis.
Percent yield = (trial product weight ÷ product theoretical weight) × 100
The theoretical weight of acetaminophen is = 280kg
The experimental weight of the product obtained in the synthesis is = 280 kg of product -70 kg of waste = 210 kg of acetaminophen
Percent yield = (210 ÷ 280) ×100

What kind of snails reproduce asexually?
Aquarium snails can breed either asexually or sexually, depending on the species. Aquarium snails can either produce live young or deposit eggs that develop into baby snails.
There are two types of water snails: those that can breed on their own and those that require contact with other snails. Once they reach adulthood, these snails use their internal male and female organs to procreate (asexually), which allows them to do so far more quickly than heterosexual species. Since they have both male and female reproductive organs, many aquarium snail species may reproduce on their own.
Snails vary from most other creatures in that they have a very unique method of reproduction. Since they are hermaphrodites, they possess both female and male sex. They have both female and male organs at the same time since they are hermaphrodites.
