Answer:
body size
more
circulatory system
egg deposition
Explanation:
Because of their large <em>body size</em> , ancestral amphibians likely faced challenges supporting themselves out of the aquatic environment.
Although there was far <em>more</em> oxygen available to gills in air than in water, the delicate structure of gills couldn't be supported in the terrestrial environment.
The costs of locomotion on land and greater oxygen demand from enlarged muscles led to modifications of the heart and <em>circulatory system</em>
These early amphibians could not venture too far away from water because <em>egg deposition</em> was restricted to moist environments.
Answer:
The main natural carbon sinks are plants, the ocean and soil. Plants grab carbon dioxide from the atmosphere to use in photosynthesis; some of this carbon is transferred to soil as plants die and decompose. The oceans are a major carbon storage system for carbon dioxide.
Explanation:
You had the right idea about the other option, generally if something is organic it has some sort of atom of carbon within the molecular compound so that limits between the two answers.
The compound is COOH meaning it is a CO² + H (Carbon dioxide + hydrogen)
It becomes an acid because the Hydrogen is a negatively charged ion and makes the compound acidic when bonded to the O
This is a type of acid that also occurs is amino acids, the building blocks of life.
I can answer it I just need to see the pictures! Message me when you upload them. It will be to do with the turgidity of the cell and the vacuole
