Answer:
Refraction
Explanation:
C. The light is bent and transmitted
Answer:
B. It's much harder to provide the right atmospheric environment to cultivate obligate anaerobes, so it's been harder to study them.
Explanation:
Obligate anaerobic bacteria are the ones that can grow only in the absence of oxygen. These bacteria do not derive the energy from aerobic cellular respiration and die when exposed to the presence of oxygen.
Owing to their oxygen sensitivity, the culturing of obligate anaerobic bacteria requires special equipment to ensure the absence of oxygen.
The presence of aerobic conditions in laboratories makes their culture and study harder than that of the aerobic or facultative anaerobic bacteria.
In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. ... If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. ... When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Answer:
The correct answer is D Sister Chromatids may not attach to each other.
Explanation:
Centromeres are the specific point to which the sister Chromatid binds.That means Centromere function to hold the sister Chromatids.
Now according to the question if mutation causes formation of defective centromere then the normal functioning of that centromere will be hampered.
As a result the sister chromatid may not attach to each other.
