Answer:
Roots---xylem vessel-- upper parts of plant.
Explanation:
The plant absorb water from hairs present on the roots and taken this water to the xylem vessel that is responsible for transporting water to all parts of the plant body. Water enters in the root through a process is called osmosis until it reached to the xylem vessel. Osmosis is a movement of molecules through a semi-permeable membrane into a region of higher solute concentration in order to equalize the solute concentration.
Answer:
Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020)
.
Explanation:
Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.
You can read these articles that are certainly clarifying in the description of his experiments and discoveries:

Answer:
True.
Explanation:
Genetic drift occurs when a species migrates into another one, therefore making a new variation of the species.
Answer:
Type II Hypersensitivity
Explanation:
Hypersensitivity reactions are exaggerated immune responses that are detrimental to the host and Type II Hypersensitivity is also known as antibody-mediated hypersensitivity.
This type of hypersensitivity reaction involves humoral immunity and it occurs when IgM or IgG antibodies bind to cell surface antigens which lead to complement activation or IgG/FcγR interaction.
Clinical manifestations of Type II hypersensitivity responses include trans- fusion reactions, hemolytic disease of the newborn, autoimmune reactions to cellular antigens or tissues and hyperacute rejection of transplanted tissue.
