Cells destroy the DNA of genes that they do not use.
When cells divide in mitosis, they pass on only the genes that are required.
To become specialized, cells need to control the production of proteins coded for in their DNA.
All genetic information in a cell's DNA is fully expressed at all times.
Answer:
To become specialized, cells need to control the production of proteins coded for in their DNA.
Explanation:
-there is an aquatic biome where fish, whales, sharks, sea snakes, dolphin...etc have to live in water as their gills cannot breathe in oxygen air they need you can say oxygen water and they can filter the waste gasses.
- there is an desert biome you have animlas such as the Fennec fox, camels, lizards, armadillos, scorpions...etc they can live in the desert bc they can make their water stay in they're body's or even save water in they're bodys. some animals even have thick layer skin so that their moisture doesnt loss
- there is the forest biome where snakes, frogs, types of bugs, monkey, fox, birds, bats, even tigers....etc in a forest there is mostly everything you can find for animals of their needings such as rivers, rivers with fish in it, other animal preys, lots of greens for herbivores, shelter, huge tress for birds to live in, caves for bears or other animals to live in dirt for insects to dig in and make a home or even rabbits, alot of fresh air, the enviroment temperature can be cold or hot...etc
- same thing goes for tropical rain forests but tropical rain forests contain more moist and greens (tress, plants..etc) and in a tropical forest its never dry! in a tropical forest you can find animals similar to the regular forest except sloth, toucans, parrots, capybara, anacondas, howler monkeys..etc animals you can find in a regular forest.
- grasslands is where the whole area is coverd in grass, or wheat, or some plant plantation, here you can find horses, cows, sheep( in the more greener grasslands), ferrets, lions, cheetahs, giraffes, zebras, antelopes, you can find too. in grass lands you basically have animals who live with out shelter (or unless under a tree or cave sth) cuz basically animals in grass lands usually travel in pairs and sleep in pairs and eat in pairs cuz its much more safer. and you could find river streams or ponds.
i gave you four biome! and it took long to long to write XD
Biomes are distinct biological communities formed in response to a shared physical climate. They include aquatic, desert, forest, grassland, and tundra biomes, each with organisms that have specific adaptations for survival.
Biomes are distinct biological communities that have formed in response to a shared physical climate. They can be categorized into five major types: aquatic, desert, forest, grassland, and tundra.
In each biome, organisms have developed physical and behavioral adaptations over time to survive within these distinct ecosystems.
