During meiosis the parent cells are eventually split into four cells that aren't identical at all. During meiosis 1 crossing over occurs which causes the chromosomes to basically get all mixed up
The control center would be the nucleus.
& I believe Messenger RNA attaches to a ribosome during protein synthesis.
The type of organisms that take energy by eating up other organisms in an ecosystem are called 'CONSUMERS'. Now these consumers are further divided into three major classes:
1. Primary consumers: this type of consumers feed directly from the producers (plants) and they only eat grass, leaves, vegetables, etc. Such animals are also called herbivores. Example: rabbit
2. Secondary consumers: these are the animals that eat up primary consumers (animals that feed only on plants). These animals are called carnivores. Example: snake
3. Tertiary consumers: animals that eat carnivores which eats a herbivore are called tertiary consumers. They can be completely carnivore or omnivore (who feed on animals and plants both). Example: humans (they feed on animals and plants both)
B. Embryos are being collected by the student on the field trip.
