Answer:
Cyanobacteria are capable of photosynthesizing. The key difference between bacteria and cyanobacteria is that bacteria do not produce free oxygen during their photosynthesis while cyanobacteria are capable of producing free oxygen during the photosynthesis.
A volcano talking to the other volcanoes about how he erupted?
Answer:
1. D. Evaporation
2. A. A closed lake has no outlet stream.
3. C. The angle of the slope
4. C. Granite
Explanation:
1. The process through which water changes its state from liquid to gaseous is known as evaporation. A source of energy is required for this process to occur, energy that is provided by solar heat in this case. The opposite process in which water changes state from gas to liquid, is known as condensation. Precipitation is the process in which the condensed water reaches the Earth’s surface under the force of gravity. During infiltration, water on the ground surface enters the soil.
2. A closed lake is defined by the lack of any outflow. Thus, any water that does not evaporate, will remain in this type of lake indefinitely.
3. The only criterion not used to describe a mass movement event is the angle of the slope. For such an event, the type of motion is the most important characteristic together with the physical characteristics of the material.
4. Granite is a highly consolidated material and thus it has a very high integrity. The other materials listed have inferior characteristics.
5. Soil erosion is a displacement process that occurs naturally though the action of water and wind. On a steep slope, no soil formation occurs, because, due to gravity, all the eroded material will be transported to another location. Thus, at the slope’s location, no soil formation occurs.
The type of solution in each beaker based on cell's reaction are :
- Isotonic solution : Normal reaction
- Hypotonic solution : The cell becomes turgid
- Hypertonic solution : The cell becomes deformed
<h3>Matching each solution to the cell reaction </h3>
When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.
Hence we can conclude that The type of solution in each beaker based on cell's reaction are : Isotonic solution : Normal reaction, Hypotonic solution : The cell becomes turgid, Hypertonic solution : The cell becomes deformed

The statement in the given question that presents a condition of the Hardy-Weinberg principle is that random mating occurs. The correct option among all the options given in the question is option "C".
There are definitely certain
conditions under which the Hardy- Weinberg principle occurs and they are when
there is no gene flow, no mutations happen, no generic drift occurs and random
mating occurs. This principle also states a very important aspect and it is
that genotype and allele frequencies will always remain constant from one
generation to another if there is absence of other evolutionary inflrnce.
