The third and last option is correct.
Species in the past (referring to dinosaurs) were more massive.
levels where higher in the past, which meant that plants prospered during that time since they had a easy access to food. That contributes to the fact that herbivores could grow bigger because there was more food. Which in turn, increases the size of early carnivores which eat bigger herbivores.
Hope it helped,
Happy homework/ study/ exam!
Explanation:
The fruits protect the seeds enclosed in the ovary. The seeds mature in the fruit by taking essential requirements.
The mature seeds retain the capacity of germination for a long period. It may be dispersed individually or along with the fruits to long distances by different agencies. The seeds germinate in the favorable conditions.
These are the advantages of fruits and seeds in the Angiosperms. These advantages help the spread of the Angiosperms in different climatic conditions. Thank you
The relationship between the garter snakes and rough-skinned newts is their evolutionary race.
Grater snakes are resistant to the TTX (the toxin of the rough-skinned newts).
TTX-resistant snakes (resistance was formed via mutation) cause natural selection to favor ever-more poisonous newts (so they can survive), and the “new” newts drive selection for higher resistance in snakes.
It is the spinal cord. Signals reach teh spinal cord, and then are transferred to the brain.<span />
