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.

Explanation:
Igneous rock is formed through the cooling and solidification of magma or lava.
The correct answer is B. Contact comfort
Explanation:
Studies with Rhesus monkeys were carried out by the psychologists Harry Harlow to study psychological and emotional aspects related to maternal separation and isolation. In this experiment, Harlow used baby monkeys and observed their behavior in different situations that included separating the baby and the mother, providing a fake mother, isolating baby monkeys for a long time and allowing baby monkeys to choose between their mother or food. The results of this experiment showed mother-infant emotional bonds were key for the development and socialization of monkeys, this could be explained as mother monkeys provided contact comfort which supported a positive development and prevailed over food or nourishment.
The parent cells are diploid.
Answer:
In the most common forms of oculocutaneous albinism, both parents must carry the albinism gene for a child to be born with the condition. Even if both parents carry the gene, the chance of each of their children being born with albinism is one in four.
