Answer:
The nucleus
Explanation:
It is the control center of the cell. It contains DNA, which tells the cell what proteins are to be made.
Answer:
The water vascular system of echinoderms (B) functions in locomotion and feeding.
Which of the following combinations of phylum and description is correct? (C) Platyhelminthes—flatworms, gastrovascular cavity, no body cavity
Explanation:
Echinoderms are marine animals. They have a water vascular system that make them able to move (locomation), respiration and food and waste transportation. This system is full of different canal along the body.
Echinodermata has not a radial symmetry as a larva, in fact it has a bilateral symmetry and coelom present. When it comes to Nematoda, they are roundworms and have a pseudocoelomate. Finally, porifera has a gastrovascular cavity and no coelom.
The basis of classification of
Linnaeus’ system is sexual reproduction. The
only "natural" taxon in Linnaeus' system is the species. Species defined
as a population with viable, fertile reproduction are separated from
interbreeding with other species.
The two resulting populations will evolve and adapt differently over time to the different ranges as the conditions change in both ranges.
Their color, size, lifespan, and consumption choices may change with that.
After all of this takes place, you're left with 2 new breeds/species of butterflies.
Hope I helped :)
