One reason that atp is a source of energy is that the products of atp hydrolysis have less free energy
Svetlanka [38]
Correct! molecules going through reactions always want to form products that are less in energy so that molecules can be more stable. ATP molecule when made is not very stable and so it is high in energy. So when hydrolyzed, it breaks down to something simple and releases energy and achieves a less free energy (deltaG) state

Plants and algae most recently shared a common ancestor 480 million years ago, and plants colonized land shortly after that. Lig
densk [106]

Answer:

The correct answer will be- the vascular system

Explanation:

The plants and algae evolved from a common ancestor and studies have also found that the algae-like Chara also evolved into plants.

The plants became adapted to grow in the terrestrial habitat by modifying themselves. The modification was that they developed the vascular system which helps them in conduction of the nutrients and water from the soil to the top of the plants and also the food to every part of the plant.

The plants also added the deposition of the cutin layer over their structure which allows the plants to stand straight and few amounts of loss of water from the plants.

Thus, the vascular system is the correct answer.

Some species of moose are adapted to eat grasses and flowers in the summer and pine needles in the winter.
Shtirlitz [24]

Answer:

The moose are adapted to live in cold regions where it snows throughout the winter.

Explanation:

These moose have adapted this way because in the winter there is snow on the ground so they do not have access to the grass and flowers they are used to eating. They then adapt to eating pine needles when the ground is covered in snow.
