Answer:
The phosphate groups of ATP are held together by unstable bonds that can be broken to release energy.
Explanation:
Biological reactions release energy from redox reactions graduallly trapped it as ATP.
ATP is the general molecule that cells use to power most of their activities. The phosphate groups of ATP are held together by unstable bonds that can be broken to release energy. ATP is a molecule under stress with too many negative charges in one place. Release of one phosphate relieves the stress and releases energy which can be used for cellular activities like transport , motility etc.
Answer:
It allows rapid conduction of water from one vessel element to the next.
Explanation:
Vessels are one of the two types of conducting cells of xylem. Vessels are made of vessel elements. Vessel elements are the individual cells with perforation plates. The perforation plates have large holes (perforations). Perforation plates of adjacent vessel elements allow easier conduction of water from one vessel element to the next.
The perforated end walls of vessel elements allow these conducting cells to conduct water more readily than tracheids. Stacking of vessel elements with perforated end walls make the vessel like a water pipe through which water is being readily conducted.
It's determined by the Sperm.
Answer:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus.
