returns freshwater to the earth
occurs after condensation
is roughly equal to the amount of evaporation
Explanation:
Precipitation returns fresh water to the earth, occurs after condensation and is roughly equal to the amount of evaporation.
The process of precipitation is a key component of the hydrologic cycle.
- In the hydrologic cycle, precipitation follows condensation of water vapor in the atmosphere.
- Precipitation often takes the form of rainfall and snow.
- It is any product of condensation of water in the atmosphere that falls back under the influence of gravity.
- In the hydrologic cycle, water leaves the surface of the earth in form of vapor as result of evaporation.
- Most times , the amount of evaporation is roughly equal to that of precipitation.

Answer:
a mucus or a gelatinous sheath
Explanation:
Most species of cyanobacteria are enclosed in a gelatinous sheath which is made up of proteins.
Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. This is called dead air space.
Alveoli are the tiny air sacs present all over the lungs. These are supposed to increase the surface area of the lungs so as to increase the amount of inhaled air. The exchange of oxygen and carbon dioxide takes place through these alveoli.
Dead air space is the unventilated area where air circulation does not take place. This air is supposed to be get trapped somewhere in the respiratory pathway or it reaches an alveoli that is poorly perfused. The dead air space can be of two types: anatomical dead space and physiologic dead space.

Answer:
The correct answer is b.Amplify the gene using PCR. Insert the gene into a plasmid vector. Transform the vector into the bacteria.
Explanation:
If I have a very small amount of gene for a fluorescent protein than the first step is to amplify the gene so that appropriate protein can be produced. PCR is the instrument that is used to amplify the protein.
So after amplification of the gene, the plasmid vector will be used in which the gene will be inserted because the plasmid vector is used to insert this gene in host cells where protein will be expressed.
The final step will be to transform bacteria with recombinant plasmid so that plasmid can make its copy and express a fluorescent protein in bulk.
