What is the fastest bivalve?

Olives are the fastest burrowers among gastropods.

Explanation:

The major classes of living mollusks include gastropods, bivalves, and cephalopods

Gastropods. Gastropods include snails and slugs. They use their foot to crawl. ...

Bivalves. Bivalves include clams, scallops, oysters, and mussels. ...

Cephalopods. Cephalopods include the octopus and squid.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
