This is possible because when a star dies, it basically expands to its maximum (explodes). Therefore, the materials of the exploded star mix with the primeval hydrogen of the Universe. Later, other stars are formed out of this mixture. Thats also how the sun was formed. :)

Water is able to travel against gravity, from the roots of a plant to the leaves at the top of the plant.

Juliette [100K]

Answer:

<em>The correct option is B) Capillary action, when adhesive forces are stronger than cohesive forces.</em>

Explanation:

When water leaves from the leaves of a plant through events such as transcription, a gap is produced in the capillary action of the xylem tube. As a result, more water is drawn from the roots to fill the void. The forces of attraction between the water and the xylem tube are much greater than the intramolecular forces of water. As a result, the water flows in an upward direction due to these string adhesive forces present between the water and xylem tube.

<h2>Transforming Bacteria</h2>

Explanation:

Archaea and bacteria are different in the qualities of the cell wall and in the lipid composition of their cell membranes
<em>Bacterial cell dividers contain peptidoglycan</em>
Archaean cell wall don't have peptidoglycan, yet they may have <em>, polysaccharides, glycoproteins, or protein-based cell dividers </em>
Bacterial cell walls are made of peptidoglycan (likewise called murein), which is produced using polysaccharide chains cross-connected by abnormal peptides containing D-amino acids
