Veta las Somalis con todos
<span>Amniotic cavity is the term used for the sac which protects
an embryo from internal and external pressures. It contains the amniotic fluid which
serves as the cushion for guarding the developing embryo and the system to
which it is being fed on. It is a crucial part of pregnancy to be able to take
tests in diagnosing the fetus for possible defects and abnormalities and one of
the methods used is the amniocentesis wherein samples of the amniotic fluid are
sampled.</span>
Answer:
c. not be able to split water to provide NADH.
Explanation:
Photosynthesis, which is the process by which plant species obtain their energy, occurs in two stages viz: light dependent phase and light independent phase. The light dependent phase of photosynthesis requires the energy from sunlight, which is captured by the chlorophyll pigments in the leaves of the plant.
The light energy captured by the chlorophyll is used to split water molecule in a process called PHOTOLYSIS OF WATER. Overall, ATP and NADH (electron donor) are products of the light dependent stage, which enters the next stage to complete the photosynthetic process.
Therefore, a plant that was grown in the dark i.e. no access to light, continuously would not be able to capture light energy and hence not be able to split water to provide NADH.
Answer: the contractile vacuole
Explanation: The contractile vacuole is a star-like structure located toward the cell's posterior. This organelle aids the cell in the removal of excess water. Without it, the euglena would be able to absorb so much water through osmosis that the cell would burst.
Hope that helps
