Answer:
* Scientists use genes to explain why evolution happens.
A hypertonic solution occurs when the solute leaves the cell as there is a large salt concentration outside of the cell
Answer:
Arthropods invaded land about 100 million years before vertebrates. This fact most clearly implies that a. arthropods have had more time to co-evolve with land plants than have vertebrates
Explanation:
Arthropods are invertebrates animals. Its evolutionary ancestry dates back to the Cambrian period and they have had more time to co-evolve with land plants than have vertebrates. The vertebrates share a common ancestor. Scientists believe that the last common ancestor of all arthropods is a modular organism with each module covered by its own sclerite.
Answer:
The correct options are: A "
vestigial wings, red eyes" and D "full wings, purple eyes"
Explanation:
female parent: vg+pr+/vg pr
(phenotype - full winged and red eyes)
male parent: vgpr/vgpr
(phenotype - vestigial winged and purple eyes)
Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.
